| an analysis of community perceptions of mosquito-borne disease control and prevention in sint eustatius, caribbean netherlands. | in the caribbean, mosquito-borne diseases are a public health threat. in sint eustatius, dengue, chikungunya and zika are now endemic. to control and prevent mosquito-borne diseases, the sint eustatius public health department relies on the community to assist with the control of aedes aegypti mosquito. unfortunately, community based interventions are not always simple, as community perceptions and responses shape actions and influence behavioural responses objective: the aim of this study was t ... | 2017 | 28766466 |
| participation of 14-3-3ε and 14-3-3ζ proteins in the phagocytosis, component of cellular immune response, in aedes mosquito cell lines. | better knowledge of the innate immune system of insects will improve our understanding of mosquitoes as potential vectors of diverse pathogens. the ubiquitously expressed 14-3-3 protein family is evolutionarily conserved from yeast to mammals, and at least two isoforms of 14-3-3, the ε and ζ, have been identified in insects. these proteins have been shown to participate in both humoral and cellular immune responses in drosophila. as mosquitoes of the genus aedes are the primary vectors for arbov ... | 2017 | 28764795 |
| cell fusing agent virus and dengue virus mutually interact in aedes aegypti cell lines. | the genus flavivirus contains more than 70 single-stranded, positive-sense arthropod-borne rna viruses. some flaviviruses are particularly medically important to humans and other vertebrates including dengue virus (denv), west nile virus, and yellow fever virus. these viruses are transmitted to vertebrates by mosquitoes and other arthropod species. mosquitoes are also infected by insect-specific flaviviruses (isfs) that do not appear to be infective to vertebrates. cell fusing agent virus (cfav) ... | 2017 | 28761113 |
| a mosquito entomoglyceroporin, aedes aegypti aqp5 participates in water transport across the malpighian tubules of larvae. | the mosquito, aedes aegypti, is the primary vector for arboviral diseases such as zika fever, dengue fever, chikungunya, and yellow fever. the larvae reside in hypo-osmotic freshwater habitats, where they face dilution of their body fluids from osmotic influx of water. the malpighian tubules help maintain ionic and osmotic homeostasis by removing excess water from the hemolymph, but the transcellular pathway for this movement remains unresolved. aquaporins are transmembrane channels thought to p ... | 2017 | 28760831 |
| evidence of dengue and chikungunya virus co-infection and circulation of multiple dengue serotypes in a recent indian outbreak. | in india, dengue endemic areas overlap with chikungunya-affected areas and both the viruses are transmitted by same vector, aedes aegypti - thereby increasing opportunity of co-infection by both viruses. present study was carried out to understand the denv-chikv infection dynamics during recent outbreaks in eastern india (west bengal state) and its implication on disease manifestations. blood was collected from 326 symptomatic febrile patients. patients' serum was subjected to serological diagno ... | 2017 | 28756561 |
| mosquitocidal potential of silver nanoparticles synthesized using local isolates of bacillus thuringiensis subsp. israelensis and their synergistic effect with a commercial strain of b. thuringiensis subsp. israelensis. | control of larval stages of aedes aegypti is considered an effective approach for preventing outbreaks of dengue fever. in this work, silver nanoparticles (ag nps) were synthesized using the supernatant and insecticidal proteins from local isolates of bacillus thuringiensis subsp. israelensis (bti). mosquitocidal activity assays against a. aegypti larvae revealed that the highest toxicity was obtained from the ag nps synthesized using supernatant of bti k55 and the inclusion proteins of bti k46 ... | 2017 | 28754251 |
| amino acid metabolic signaling influences aedes aegypti midgut microbiome variability. | the mosquito midgut microbiota has been shown to influence vector competence for multiple human pathogens. the microbiota is highly variable in the field, and the sources of this variability are not well understood, which limits our ability to understand or predict its effects on pathogen transmission. in this work, we report significant variation in female adult midgut bacterial load between strains of a. aegypti which vary in their susceptibility to dengue virus. composition of the midgut micr ... | 2017 | 28753661 |
| dengue subgenomic flaviviral rna disrupts immunity in mosquito salivary glands to increase virus transmission. | globally re-emerging dengue viruses are transmitted from human-to-human by aedes mosquitoes. while viral determinants of human pathogenicity have been defined, there is a lack of knowledge of how dengue viruses influence mosquito transmission. identification of viral determinants of transmission can help identify isolates with high epidemiological potential. additionally, mechanistic understanding of transmission will lead to better understanding of how dengue viruses harness evolution to cycle ... | 2017 | 28753642 |
| insecticide resistance, associated mechanisms and fitness aspects in two brazilian stegomyia aegypti (= aedes aegypti) populations. | in brazil, insecticide resistance in stegomyia aegypti (= aedes aegypti) (diptera: culicidae) populations to pyrethroids and to the organophosphate (op) temephos is disseminated. currently, insect growth regulators (igrs) and the op malathion are employed against larvae and adults, respectively. bioassays with mosquitoes from two northeast municipalities, crato and aracaju, revealed, in both populations, susceptibility to igrs and malathion (rr95 ≤ 2.0), confirming the effectiveness of these co ... | 2017 | 28752548 |
| a mosquito hemolymph odorant-binding protein family member specifically binds juvenile hormone. | juvenile hormone (jh) is a key regulator of insect development and reproduction. in adult mosquitoes, it is essential for maturation of the ovary and normal male reproductive behavior, but how jh distribution and activity is regulated after secretion is unclear. here, we report a new type of specific jh-binding protein, given the name mosquito juvenile hormone-binding protein (mjhbp), which circulates in the hemolymph of pupal and adult aedes aegypti males and females. mjhbp is a member of the o ... | 2017 | 28751377 |
| a cross-sectional survey of aedes aegypti immature abundance in urban and rural household containers in central colombia. | aedes aegypti, the major vector of dengue, breeds in domestic water containers. the development of immature mosquitoes in such containers is influenced by various environmental, ecological and socioeconomic factors. urban and rural disparities in water storage practices and water source supply may affect mosquito immature abundance and, potentially, dengue risk. we evaluated the effect of water and container characteristics on a. aegypti immature abundance in urban and rural areas. data were col ... | 2017 | 28750651 |
| transmission risk of two chikungunya lineages by invasive mosquito vectors from florida and the dominican republic. | between 2014 and 2016 more than 3,800 imported human cases of chikungunya fever in florida highlight the high risk for local transmission. to examine the potential for sustained local transmission of chikungunya virus (chikv) in florida we tested whether local populations of aedes aegypti and aedes albopictus show differences in susceptibility to infection and transmission to two emergent lineages of chikv, indian ocean (ioc) and asian genotypes (ac) in laboratory experiments. all examined popul ... | 2017 | 28749964 |
| aedes ægypti control in urban areas: a systemic approach to a complex dynamic. | the available strategy for controlling the diseases transmitted by aedes ægypti (dengue fever, zika, and chikungunya) relies on continued community participation. despite slogans emphasizing how easy it should be, no country has achieved it since the seventies. to better investigate potentially sustainable interventions, we developed a systemic model based on a multidisciplinary approach, integrating as deeply as possible specialized knowledge and field experience. the resulting model is compose ... | 2017 | 28749942 |
| larvicidal activity prediction against aedes aegypti mosquito using computational tools. | aedes aegypti is an important vector for transmission of dengue, yellow fever, chikun- gunya, arthritis, and zika fever. according to the world health organization, it is estimated that ae. aegypti causes 50 million infections and 25,000 deaths per year. use of larvicidal agents is one of the recommendations of health organizations to control mosquito populations and limit their distribution. the aim of present study was to deduce a mathematical model to predict the larvicidal action of chemical ... | 2017 | 28748838 |
| could the recent zika epidemic have been predicted? | given knowledge at the time, the recent 2015-2016 zika virus (zikv) epidemic probably could not have been predicted. without the prior knowledge of zikv being already present in south america, and given the lack of understanding of key epidemiologic processes and long-term records of zikv cases in the continent, the best related prediction could be carried out for the potential risk of a generic aedes-borne disease epidemic. here we use a recently published two-vector basic reproduction number m ... | 2017 | 28747901 |
| copper ii - polar amino acid complexes: toxicity to bacteria and larvae of aedes aegypti. | control strategies using insecticides are sometimes ineffective due to the resistance of the insect vectors.in this scenario new products must be proposed for the control of insect vectors.the complexes l-aspartate cu (ii) and l-glutamate-cu (ii) complexes were synthesized and characterized by elemental analysis, visible ultraviolet, infrared spectroscopy and potentiometric titration. the toxicity of these complexes was analyzed in aedes aegypti (diptera: culicidae) larvae and gram-negative and ... | 2017 | 28746551 |
| dengue serotype circulation in natural populations of aedes aegypti. | ae. aegypti is the main vector of dengue (denv), zika (zikv), and chikungunya (chikv) viruses. the transmission dynamics of these arboviruses, especially the arboviral circulation in the mosquito population during low and high transmission seasons in endemic areas are still poorly understood. we conducted an entomological survey to determine dengue infection rates in ae. aegypti and aedes albopictus. these collections were performed in 2012-2013 during a rio de janeiro epidemic, just before the ... | 2017 | 28743449 |
| tracking the return of aedes aegypti to brazil, the major vector of the dengue, chikungunya and zika viruses. | aedes aegypti, commonly known as "the yellow fever mosquito", is of great medical concern today primarily as the major vector of dengue, chikungunya and zika viruses, although yellow fever remains a serious health concern in some regions. the history of ae. aegypti in brazil is of particular interest because the country was subjected to a well-documented eradication program during 1940s-1950s. after cessation of the campaign, the mosquito quickly re-established in the early 1970s with several de ... | 2017 | 28742801 |
| insecticide resistance is mediated by multiple mechanisms in recently introduced aedes aegypti from madeira island (portugal). | aedes aegypti is a major mosquito vector of arboviruses, including dengue, chikungunya and zika. in 2005, ae. aegypti was identified for the first time in madeira island. despite an initial insecticide-based vector control program, the species expanded throughout the southern coast of the island, suggesting the presence of insecticide resistance. here, we characterized the insecticide resistance status and the underlying mechanisms of two populations of ae. aegypti from madeira island, funchal a ... | 2017 | 28742096 |

| wolbachia and dengue virus infection in the mosquito aedes fluviatilis (diptera: culicidae). | dengue represents a serious threat to human health, with billions of people living at risk of the disease. wolbachia pipientis is a bacterial endosymbiont common to many insect species. wolbachia transinfections in mosquito disease vectors have great value for disease control given the bacterium's ability to spread into wild mosquito populations, and to interfere with infections of pathogens, such as dengue virus. aedes fluviatilis is a mosquito with a widespread distribution in latin america, b ... | 2017 | 28732048 |
| assessment of the probability of autochthonous transmission of chikungunya virus in canada under recent and projected climate change. | chikungunya virus (chikv) is a reemerging pathogen transmitted by aedes aegypti and aedes albopictus mosquitoes. the ongoing caribbean outbreak is of concern due to the potential for infected travelers to spread the virus to countries where vectors are present and the population is susceptible. although there has been no autochthonous transmission of chikv in canada, there is concern that both ae. albopictus and chikv will become established, particularly under projected climate change. we devel ... | 2017 | 28731409 |
| conditions for success of engineered underdominance gene drive systems. | engineered underdominance is one of a number of different gene drive strategies that have been proposed for the genetic control of insect vectors of disease. here we model a two-locus engineered underdominance based gene drive system that is based on the concept of mutually suppressing lethals. in such a system two genetic constructs are introduced, each possessing a lethal element and a suppressor of the lethal at the other locus. specifically, we formulate and analyse a population genetics mod ... | 2017 | 28728996 |
| zika virus transmission to mouse ear by mosquito bite: a laboratory model that replicates the natural transmission process. | zika disease has transformed into a serious global health problem due to the rapid spread of the arbovirus and alarming severity including congenital complications, microcephaly and guillain-barré syndrome. zika virus (zikv) is primarily transmitted to humans through the bite of an infective mosquito, with aedes aegypti being the main vector. | 2017 | 28728607 |
| rhanterium epapposum oliv. essential oil: chemical composition and antimicrobial, insect-repellent and anticholinesterase activities. | the essential oil (eo) of the aerial parts of rhanterium epapposum oliv. (asteraceae), was obtained by hydrodistillation. the oil was subsequently analyzed by both gc-fid and gc-ms, simultaneously. forty-five components representing 99.2% of the oil composition were identified. the most abundant compounds were camphene (38.5%), myrcene (17.5%), limonene (10.1%) and α-pinene (8.7%). referring to the ethnobotanical utilization, an insecticidal assay was performed, where the oil repelled the yellow ... | 2017 | 28725142 |
| asymptomatic transmission and the dynamics of zika infection. | following the 2013-14 outbreak in french polynesia, the zika virus (zikv) epidemic spread widely to many countries where aedes aegypti as the main transmitting vector is endemic. the lack of a second wave of zikv infection in most affected regions may suggest that a sufficiently high level of herd immunity was reached during the first wave. we developed an agent-based transmission model to investigate the role of asymptomatic infection on the likelihood of observing a second wave, while accounti ... | 2017 | 28724972 |
| first record of natural vertical transmission of dengue virus in aedes aegypti from cuba. | while horizontal transmission (human-mosquito-human) of dengue viruses largely determines the epidemiology of the disease, vertical transmission (infected female mosquito- infected offspring) has been suggested as a mechanism that ensures maintenance of the virus during adverse conditions for horizontal transmission to occur. the purpose of this study was to analyze the natural infection of larval stages of aedes aegypti (diptera: culicidae) with the dengue virus (denv) in cuba. here, we report ... | 2017 | 28720490 |
| experimental infection with and maintenance of cell fusing agent virus (flavivirus) in aedes aegypti. | during the past two decades, there has been a dramatic increase in the recognition and characterization of novel insect-specific flaviviruses (isfvs). some of these agents are closely related to important mosquito-borne flavivirus pathogens. results of experimental studies suggest that mosquitoes and mosquito cell cultures infected with some isfvs are refractory to superinfection with related flavivirus pathogens; and it has been proposed that isfvs potentially could be used to alter the vector ... | 2017 | 28719335 |
| american aedes vexans mosquitoes are competent vectors of zika virus. | abstractstarting in 2013-2014, the americas have experienced a massive outbreak of zika virus (zikv) which has now reached at least 49 countries. although most cases have occurred in south america and the caribbean, imported and autochthonous cases have occurred in the united states. aedes aegypti and aedes albopictus mosquitoes are known vectors of zikv. little is known about the potential for temperate aedes mosquitoes to transmit zikv. aedes vexans has a worldwide distribution, is highly abun ... | 2017 | 28719283 |
| low density lipopolyprotein inhibits flavivirus acquisition in aedes aegypti. | aedes aegypti is the primary vector of a number of human pathogens including dengue virus (denv) and zika virus (zikv). ae. aegypti acquires these viruses during the processing of bloodmeals obtained from an infected vertebrate host. vertebrate blood contains a number of factors that have the potential to modify virus acquisition in the mosquito. interestingly, low density lipopolyprotein (ldl) levels are decreased during severe denv infection. accordingly, we hypothesized that ldl is a modifiab ... | 2017 | 28718976 |
| zika virus alters the microrna expression profile and elicits an rnai response in aedes aegypti mosquitoes. | zika virus (zikv), a flavivirus transmitted primarily by aedes aegypti, has recently spread globally in an unprecedented fashion, yet we have a poor understanding of host-microbe interactions in this system. to gain insights into the interplay between zikv and the mosquito, we sequenced the small rna profiles in zikv-infected and non-infected ae. aegypti mosquitoes at 2, 7 and 14 days post-infection. zika induced an rnai response in the mosquito with virus-derived short interfering rnas and piwi ... | 2017 | 28715413 |
| mosquitoes can harbour yeasts of clinical significance and contribute to their environmental dissemination. | there is still a lack of studies on fungal microbiota in mosquitoes, compared with the number available on bacterial microbiota. this study reports the identification of yeasts of clinical significance in laboratory mosquito species: anopheles gambiae, anopheles stephensi, culex quinquefasciatus, aedes albopictus and aedes aegypti. among the yeasts isolated, they focused on the opportunistic pathogen candida parapsilosis, since there is a need to better understand breakthrough candidaemia with r ... | 2017 | 28714286 |
| toward mosquito control with a green alga: expression of cry toxins of bacillus thuringiensis subsp. israelensis (bti) in the chloroplast of chlamydomonas. | we are developing chlamydomonas strains that can be used for safe and sustainable control of mosquitoes, because they produce proteins from bacillus thuringiensis subsp. israelensis (bti) in the chloroplast. chlamydomonas has a number of advantages for this approach, including genetic controls that are not generally available with industrial algae. the bti toxin has been used for mosquito control for > 30 years and does not engender resistance; it contains three cry proteins, cry4aa (135 kda), c ... | 2017 | 28713202 |
| specificity and putative mode of action of a mosquito larvicidal toxin from the bacterium xenorhabdus innexi. | reduction of mosquito-borne diseases relies, in part, on the use of synthetic pesticides to control pest mosquitoes. this reliance has led to genetic resistance, environmental contamination and the nondiscriminatory elimination of both pest and non-pest species. to expand our options for control, we screened entomopathogenic bacteria for potential larvicidal activity. a lipopeptide from the bacterium, xenorhabdus innexi, was discovered that displayed potent larvicidal activity. the lc50s of the ... | 2017 | 28712711 |
| characterization and productivity profiles of aedes aegypti (l.) breeding habitats across rural and urban landscapes in western and coastal kenya. | aedes aegypti, the principal vector for dengue and other emerging arboviruses, breeds preferentially in various man-made and natural container habitats. in the absence of vaccine, epidemiological surveillance and vector control remain the best practices for preventing dengue outbreaks. effective vector control depends on a good understanding of larval and adult vector ecology of which little is known in kenya. in the current study, we sought to characterize breeding habitats and establish contai ... | 2017 | 28701194 |
| understanding the role of micrornas in the interaction of aedes aegypti mosquitoes with an insect-specific flavivirus. | the flavivirus genus contains some of the most prevalent vector-borne viruses, such as the dengue, zika and yellow fever viruses that cause devastating diseases in humans. however, the insect-specific clade of flaviviruses is restricted to mosquito hosts, albeit they have retained the general features of the genus, such as genome structure and replication. the interactions between insect-specific flaviviruses (isfs) and their mosquito hosts are largely unknown. pathogenic flaviviruses are known ... | 2017 | 28699859 |
| camino verde (the green way): evidence-based community mobilisation for dengue control in nicaragua and mexico: feasibility study and study protocol for a randomised controlled trial. | since the aedes aegypti mosquitoes that transmit dengue virus can breed in clean water, who-endorsed vector control strategies place sachets of organophosphate pesticide, temephos (abate), in household water storage containers. these and other pesticide-dependent approaches have failed to curb the spread of dengue and multiple dengue virus serotypes continue to spread throughout tropical and subtropical regions worldwide. a feasibility study in managua, nicaragua, generated instruments, interven ... | 2017 | 28699570 |
| which green way: description of the intervention for mobilising against aedes aegypti under difficult security conditions in southern mexico. | community mobilisation for prevention requires engagement with and buy in from those communities. in the mexico state of guerrero, unprecedented social violence related to the narcotics trade has eroded most community structures. a recent randomised controlled trial in 90 coastal communities achieved sufficient mobilisation to reduce conventional vector density indicators, self-reported dengue illness and serologically proved dengue virus infection. | 2017 | 28699562 |
| mobilising communities for aedes aegypti control: the sepa approach. | camino verde (the green way) is an evidence-based community mobilisation tool for prevention of dengue and other mosquito-borne viral diseases. its effectiveness was demonstrated in a cluster-randomised controlled trial conducted in 2010-2013 in nicaragua and mexico. the common approach that brought functional consistency to the camino verde intervention in both mexico and nicaragua is socialisation of evidence for participatory action (sepa). in this article, we explain the sepa concept and its ... | 2017 | 28699561 |
| aedes aegypti breeding ecology in guerrero: cross-sectional study of mosquito breeding sites from the baseline for the camino verde trial in mexico. | understanding the breeding patterns of aedes aegypti in households and the factors associated with infestation are important for implementing vector control. the baseline survey of a cluster randomised controlled trial of community mobilisation for dengue prevention in mexico and nicaragua collected information about the containers that are the main breeding sites, identified possible actions to reduce breeding, and examined factors associated with household infestation. this paper describes fin ... | 2017 | 28699559 |
| beyond efficacy in water containers: temephos and household entomological indices in six studies between 2005 and 2013 in managua, nicaragua. | a cluster-randomized controlled trial of community mobilisation for dengue prevention in mexico and nicaragua reported, as a secondary finding, a higher risk of dengue virus infection in households where inspectors found temephos in water containers. data from control sites in the preceding pilot study and the nicaragua trial arm provided six time points (2005, 2006, 2007 and 2011, 2012, 2013) to examine potentially protective effects of temephos on entomological indices under every day conditio ... | 2017 | 28699558 |
| "where we put little fish in the water there are no mosquitoes:" a cross-sectional study on biological control of the aedes aegypti vector in 90 coastal-region communities of guerrero, mexico. | in the mexican state of guerrero, some households place fish in water storage containers to prevent the development of mosquito larvae. studies have shown that larvivorous fish reduce larva count in household water containers, but there is a lack of evidence about whether the use of fish is associated with a reduction in dengue virus infection. we used data from the follow up survey of the camino verde cluster randomised controlled trial of community mobilisation to reduce dengue risk to study t ... | 2017 | 28699557 |
| pupal productivity in rainy and dry seasons: findings from the impact survey of a randomised controlled trial of dengue prevention in guerrero, mexico. | the follow-up survey of a cluster-randomised controlled trial of evidence-based community mobilisation for dengue control in nicaragua and mexico included entomological information from the 2012 rainy and dry seasons. we used data from the mexican arm of the trial to assess the impact of the community action on pupal production of the dengue vector aedes aegypti in both rainy and dry seasons. | 2017 | 28699555 |
| coverage and beliefs about temephos application for control of dengue vectors and impact of a community-based prevention intervention: secondary analysis from the camino verde trial in mexico. | temephos in domestic water containers remains a mainstay of latin american government programmes for control of aedes aegypti and associated illnesses, including dengue. there is little published evidence about coverage of routine temephos programmes. a cluster randomised controlled trial of community mobilisation in mexico and nicaragua reduced vector indices, dengue infection, and clinical dengue cases. secondary analysis from the mexican arm of the trial examined temephos coverage and beliefs ... | 2017 | 28699554 |
| assessing the effects of interventions for aedes aegypti control: systematic review and meta-analysis of cluster randomised controlled trials. | the aedes aegypti mosquito is the vector for dengue fever, yellow fever, chikungunya, and zika viruses. inadequate vector control has contributed to persistence and increase of these diseases. this review assesses the evidence of effectiveness of different control measures in reducing aedes aegypti proliferation, using standard entomological indices. | 2017 | 28699552 |
| the camino verde intervention in nicaragua, 2004-2012. | camino verde (the green way) is an evidence-based community mobilisation tool for prevention of dengue and other mosquito-borne viral diseases. its effectiveness was demonstrated in a cluster-randomised controlled trial conducted in 2010-2013 in nicaragua and mexico. the nicaraguan arm of the trial was preceded, from 2004 to 2008, by a feasibility study that provided valuable lessons and trained facilitators for the trial itself. here, guided by the template for intervention description and repl ... | 2017 | 28699551 |
| when communities are really in control: ethical issues surrounding community mobilisation for dengue prevention in mexico and nicaragua. | we discuss two ethical issues raised by camino verde, a 2011-2012 cluster-randomised controlled trial in mexico and nicaragua, that reduced dengue risk though community mobilisation. the issues arise from the approach adopted by the intervention, one called socialisation of evidence for participatory action. community volunteer teams informed householders of evidence about dengue, its costs and the life-cycle of aedes aegypti mosquitoes, while showing them the mosquito larvae in their own water ... | 2017 | 28699548 |
| informed community mobilization for dengue prevention in households with and without a regular water supply: secondary analysis from the camino verde trial in nicaragua. | studies in different countries have identified irregular water supply as a risk factor for dengue virus transmission. in 2013, camino verde, a cluster-randomised controlled trial in managua, nicaragua, and mexico's guerrero state, demonstrated impact of evidence-based community mobilisation on recent dengue infection and entomological indexes of infestation by aedes aegypti mosquitoes. this secondary analysis of data from the trial impact survey asks: (1) what is the importance of regular water ... | 2017 | 28699544 |
| randomised controlled trials and changing public health practice. | one reason for doing randomised controlled trials (rcts) is that experiments can be convincing. early epidemiological experimenters, such as jenner and the smallpox vaccine and snow and his famous broad street pump handle, already knew the answer they were demonstrating; they used the experiments as knowledge translation devices to convince others.more sophisticated modern experiments include cluster randomised controlled trials (crcts) for experiments in the public health setting. the knowledge ... | 2017 | 28699541 |
| effect of an intervention in storm drains to prevent aedes aegypti reproduction in salvador, brazil. | aedes aegypti, the principal vector for dengue, chikungunya and zika viruses, is a synanthropic species that uses stagnant water to complete its reproductive cycle. in urban settings, rainfall water draining structures, such as storm drains, may retain water and serve as a larval development site for aedes spp. reproduction. herein, we describe the effect of a community-based intervention on preventing standing water accumulation in storm drains and their consequent infestation by adult and imma ... | 2017 | 28697811 |
| the medicinal chemistry of chikungunya virus. | arthropod-borne viruses (arboviruses) are an important threat to human and animal health globally. among these, zoonotic diseases account for billions of cases of human illness and millions of deaths every year, representing an increasing public health problem. chikungunya virus belongs to the genus alphavirus of the family togariridae, and is transmitted mainly by the bite of female mosquitoes of the aedes aegypti and/or a. albopictus species. the focus of this review will be on the medicinal c ... | 2017 | 28689975 |
| potential risk of re-emergence of urban transmission of yellow fever virus in brazil facilitated by competent aedes populations. | yellow fever virus (yfv) causing a deadly viral disease is transmitted by the bite of infected mosquitoes. in brazil, yfv is restricted to a forest cycle maintained between non-human primates and forest-canopy mosquitoes, where humans can be tangentially infected. since late 2016, a growing number of human cases have been reported in southeastern brazil at the gates of the most populated areas of south america, the atlantic coast, with rio de janeiro state hosting nearly 16 million people. we sh ... | 2017 | 28687779 |
| comparative genomics shows that viral integrations are abundant and express pirnas in the arboviral vectors aedes aegypti and aedes albopictus. | arthropod-borne viruses (arboviruses) transmitted by mosquito vectors cause many important emerging or resurging infectious diseases in humans including dengue, chikungunya and zika. understanding the co-evolutionary processes among viruses and vectors is essential for the development of novel transmission-blocking strategies. episomal viral dna fragments are produced from arboviral rna upon infection of mosquito cells and adults. additionally, sequences from insect-specific viruses and arboviru ... | 2017 | 28676109 |
| protection against mosquito vectors aedes aegypti, anopheles stephensi and culex quinquefasciatus using a novel insect repellent, ethyl anthranilate. | growing concern on the application of synthetic mosquito repellents in the recent years has instigated the identification and development of better alternatives to control different mosquito-borne diseases. in view of above, present investigation evaluates the repellent activity of ethyl anthranilate (ea), a non-toxic, fda approved volatile food additive against three known mosquito vectors namely, aedes aegypti, anopheles stephensi and culex quinquefasciatus under laboratory conditions followin ... | 2017 | 28666890 |
| high risk for chikungunya virus to initiate an enzootic sylvatic cycle in the tropical americas. | chikungunya virus (chikv) has dispersed in the americas since 2013, and its range of distribution has overlapped large forested areas. herein, we assess vector competence of two sylvatic neotropical mosquito species, haemagogus leucocelaenus and aedes terrens, to evaluate the risk of chikv to initiate a sylvatic cycle in the continent. | 2017 | 28662031 |
| effects of rearing salinity on expression and function of ion-motive atpases and ion transport across the gastric caecum of aedes aegypti larvae. | larvae of aedes aegypti, the yellow fever vector, inhabit a variety of aquatic habitats ranging from freshwater to brackish water. this study focuses on the gastric caecum of the larvae, an organ that has not been widely studied. we provide the first measurements of h+, k+ and na+ fluxes at the distal and proximal gastric caecum, and have shown that they differ in the two regions, consistent with previously reported regionalization of ion transporters. moreover, we have shown that the regionaliz ... | 2017 | 28659305 |
| wolbachia infection in aedes aegypti mosquitoes alters blood meal excretion and delays oviposition without affecting trypsin activity. | blood feeding in aedes aegypti is essential for reproduction, but also permits the mosquito to act as a vector for key human pathogens such as the zika and dengue viruses. wolbachia pipientis is an endosymbiotic bacterium that can manipulate the biology of aedes aegypti mosquitoes, making them less competent hosts for many pathogens. yet while wolbachia affects other aspects of host physiology, it is unclear whether it influences physiological processes associated with blood meal digestion. to t ... | 2017 | 28655666 |
