the transmission of equine encephalomyelitis virus by aedes aegypti.in confirming kelser's work on the transmission of equine encephalomyelitis of the western type by aëdes aegypti it has been learned that the mosquitoes must be fed virus of high titer if positive results are to be secured. a period of from 4 to 5 days after feeding either on infected guinea pigs or on brain containing virus must elapse before the disease is transmitted by biting, but after this time transmission regularly results for a period of about 2 months. by inoculation, virus can be demo ...193519870442
recent laboratory contributions to the control of yellow fever: (section of tropical diseases and parasitology).the most important recent laboratory contributions to the control of yellow fever will be briefly summarized under three headings: (1) methods of diagnosis, (2) transmission, and (3) protection.(1) methods of diagnosis.-the development of improved methods of identification, in particular by immunity tests, has made it possible to diagnose yellow fever with much greater certainty. moreover, since the immunity following an attack of the disease is usually of life-long duration, it is possible to d ...193319989606
possibility of hereditary transmission of yellow fever virus by aedes aegypti (linn.).attempts to obtain passage of yellow fever virus from one generation to the next in a. aegypti were unsuccessful. subcutaneous injections at varying intervals of a saline emulsion of 200 eggs laid by an infective lot of mosquitoes produced no reaction in six normal m. rhesus monkeys. negative results were also obtained in five biting and two injection experiments with progeny of the same infective lot of mosquitoes in which seven normal monkeys were used. the eggs consisted of batches laid after ...192919869656
the filtrability of yellow fever virus as existing in the mosquito.the virus of yellow fever as it exists in aëdes aegypti mosquitoes, both in their so-called infective stage and in the intermediate condition termed the "incubation period", is capable of passing through berkefeld n filters when suspended in normal monkey serum, although earlier investigators have shown that the virus from infective mosquitoes will not do so when suspended in physiological salt solution. the virus of yellow fever as it exists in mosquitoes behaves with regard to filtration throu ...192919869658
studies on yellow fever in south america : iv. transmission experiments with aedes aegypti.1. batches of aëdes (stegomyia) aegypti which had fed on monkeys in the early febrile stage of yellow fever and which has subsequently passed the usually accepted extrinsic incubation period for the virus, failed to transmit the disease to normal monkeys in approximately fifty per cent of the experiments. during the same time over eighty per cent of blood transfers were successful. 2. the monkeys which failed to show fever following mosquito bites later proved resistant to the inoculation of blo ...192919869665
the incubation period of yellow fever in the mosquito.1. the yellow fever virus was found in infectious form in aedes aegypti throughout the entire period of the extrinsic incubation, as demonstrated by the injection of the bodies of mosquitoes into normal rhesus monkeys at daily intervals after the insects had fed on an infected animal. 2. the virus was transmitted through the bite of the mosquitoes, in one experiment on and after the 9th day, and in two experiments on the 12th day after the initial infecting feed. 3. the pathologic changes produc ...192819869467

larval food quantity affects the capacity of adult mosquitoes to transmit human malaria.adult traits of holometabolous insects are shaped by conditions experienced during larval development, which might impact interactions between adult insect hosts and parasites. however, the ecology of larval insects that vector disease remains poorly understood. here, we used anopheles stephensi mosquitoes and the human malaria parasite plasmodium falciparum, to investigate whether larval conditions affect the capacity of adult mosquitoes to transmit malaria. we reared larvae in two groups; one ...027412284
mechanisms of arthropod transmission of plant and animal viruses.a majority of the plant-infecting viruses and many of the animal-infecting viruses are dependent upon arthropod vectors for transmission between hosts and/or as alternative hosts. the viruses have evolved specific associations with their vectors, and we are beginning to understand the underlying mechanisms that regulate the virus transmission process. a majority of plant viruses are carried on the cuticle lining of a vector's mouthparts or foregut. this initially appeared to be simple mechanical ...010066833
transcriptional pausing controls a rapid antiviral innate immune response in drosophila.innate immune responses are characterized by precise gene expression whereby gene subsets are temporally induced to limit infection, although the mechanisms involved are incompletely understood. we show that antiviral immunity in drosophila requires the transcriptional pausing pathway, including negative elongation factor (nelf) that pauses rna polymerase ii (pol ii) and positive elongation factor b (p-tefb), which releases paused pol ii to produce full-length transcripts. we identify a set of g ...023084920
the status of infectious disease in the amazon region.the amazon river basin region is a vast territory with an area >7 million km2, encompassing parts of 9 south american countries: bolivia, brazil, colombia, ecuador, french guiana, guyana, peru, suriname, and venezuela. the amazon river, the longest river in the world, traverses the region from west to east, fed by multiple tributaries. the region also contains the largest tropical rainforest in the world, situated on a massive plain whose altitude is near sea level. with a climate characterized ...019331757
assessing the epidemic potential of rna and dna viruses.many new and emerging rna and dna viruses are zoonotic or have zoonotic origins in an animal reservoir that is usually mammalian and sometimes avian. not all zoonotic viruses are transmissible (directly or by an arthropod vector) between human hosts. virus genome sequence data provide the best evidence of transmission. of human transmissible virus, 37 species have so far been restricted to self-limiting outbreaks. these viruses are priorities for surveillance because relatively minor changes in ...027869592
molecular modeling and docking study to elucidate novel chikungunya virus nsp2 protease inhibitors.chikungunya is one of the tropical viral infections that severely affect the asian and african countries. absence of any suitable drugs or vaccines against chikungunya virus till date makes it essential to identify and develop novel leads for the same. recently, nsp2 cysteine protease has been classified as a crucial drug target to combat infections caused by alphaviruses including chikungunya virus due to its involvement viral replication. here in, we investigated the structural aspects of the ...026664062
novel genetic and molecular tools for the investigation and control of dengue virus transmission by mosquitoes.aedes aegypti is the principal vector of dengue virus (denv) throughout the tropical world. this anthropophilic mosquito species needs to be persistently infected with denv before it can transmit the virus through its saliva to a new vertebrate host. in the mosquito, denv is confronted with several innate immune pathways, among which rna interference is considered the most important. the ae. aegypti genome project opened the doors for advanced molecular studies on pathogen-vector interactions in ...024693489
microbiota-dependent priming of antiviral intestinal immunity in drosophila.enteric pathogens must overcome intestinal defenses to establish infection. in drosophila, the erk signaling pathway inhibits enteric virus infection. the intestinal microflora also impacts immunity but its role in enteric viral infection is unknown. here we show that two signals are required to activate antiviral erk signaling in the intestinal epithelium. one signal depends on recognition of peptidoglycan from the microbiota, particularly from the commensal acetobacter pomorum, which primes th ...026567510
rna interference-mediated antiviral defense in insects.small interfering rna (sirna)-mediated rna interference (rnai) pathways are critical for the detection and inhibition of rna virus replication in insects. recent work has also implicated rnai pathways in the establishment of persistent virus infections and in the control of dna virus replication. accumulating evidence suggests that diverse double-stranded rnas produced by rna and dna viruses can trigger rnai responses yet many viruses have evolved mechanisms to inhibit rnai defenses. therefore, ...026034705
mosquito immune responses to arbovirus infections.the principal mosquito innate immune response to virus infections, rna interference (rnai), differs substantially from the immune response to bacterial and fungal infections. the exo-sirna pathway constitutes the major anti-arboviral rnai response and its essential genetic components have been identified. recent research has also implicated the piwi-interacting rna pathway in mosquito anti-arboviral immunity, but piwi gene-family components involved are not well-defined. arboviruses must evade o ...025401084
host inflammatory response to mosquito bites enhances the severity of arbovirus infection.aedes aegypti mosquitoes are responsible for transmitting many medically important viruses such as those that cause zika and dengue. the inoculation of viruses into mosquito bite sites is an important and common stage of all mosquito-borne virus infections. we show, using semliki forest virus and bunyamwera virus, that these viruses use this inflammatory niche to aid their replication and dissemination in vivo. mosquito bites were characterized by an edema that retained virus at the inoculation ...027332734
factors shaping the adaptive landscape for arboviruses: implications for the emergence of disease.many examples of the emergence or re-emergence of infectious diseases involve the adaptation of zoonotic viruses to new amplification hosts or to humans themselves. these include several instances of simple mutational adaptations, often to hosts closely related to the natural reservoirs. however, based on theoretical grounds, arthropod-borne viruses, or arboviruses, may face several challenges for adaptation to new hosts. here, we review recent findings regarding adaptive evolution of arboviruse ...023374123
chikungunya virus and prospects for a vaccine.in 2004, chikungunya virus (chikv) re-emerged from east africa to cause devastating epidemics of debilitating and often chronic arthralgia that have affected millions of people in the indian ocean basin and asia. more limited epidemics initiated by travelers subsequently occurred in italy and france, as well as human cases exported to most regions of the world, including the americas where chikv could become endemic. because chikv circulates during epidemics in an urban mosquito-human cycle, con ...023151166
innate antiviral immunity in drosophila.the study of drosophila, and other genetically tractable insects, has expanded our understanding of innate immunity and more recently antiviral innate mechanisms. the drosophila antiviral program includes inflammatory signaling cascades as well as antiviral rna silencing and autophagy. this review will highlight the recent discoveries in antiviral immunity in insects and will reveal some of the lessons learned.020137906

wing shape as an indicator of larval rearing conditions for aedes albopictus and aedes aegypti (diptera: culicidae).estimating a mosquito's vector competence, or likelihood of transmitting disease, if it takes an infectious bloodmeal, is an important aspect of predicting when and where outbreaks of infectious diseases will occur. vector competence can be affected by rearing temperature and inter- and intraspecific competition experienced by the individual mosquito during its larval development. this research investigates whether a new morphological indicator of larval rearing conditions, wing shape, can be us ...022897054
specificity of resistance to dengue virus isolates is associated with genotypes of the mosquito antiviral gene dicer-2.in contrast to the prevailing view that invertebrate immunity relies on broad-spectrum recognition and effector mechanisms, intrinsic genetic compatibility between invertebrate hosts and their pathogens is often highly specific in nature. solving this puzzle requires a better understanding of the molecular basis underlying observed patterns of invertebrate host-pathogen genetic specificity, broadly referred to as genotype-by-genotype interactions. here, we identify an invertebrate immune gene in ...023193131
a genome-wide rnai screen reveals that mrna decapping restricts bunyaviral replication by limiting the pools of dcp2-accessible targets for cap-snatching.bunyaviruses are an emerging group of medically important viruses, many of which are transmitted from insects to mammals. to identify host factors that impact infection, we performed a genome-wide rnai screen in drosophila and identified 131 genes that impacted infection of the mosquito-transmitted bunyavirus rift valley fever virus (rvfv). dcp2, the catalytic component of the mrna decapping machinery, and two decapping activators, ddx6 and lsm7, were antiviral against disparate bunyaviruses in ...023824541
rna interference in infectious tropical diseases.introduction of double-stranded rna (dsrna) into some cells or organisms results in degradation of its homologous mrna, a process called rna interference (rnai). the dsrnas are processed into short interfering rnas (sirnas) that subsequently bind to the rna-induced silencing complex (risc), causing degradation of target mrnas. because of this sequence-specific ability to silence target genes, rnai has been extensively used to study gene functions and has the potential to control disease pathogen ...018344671
transgene-mediated suppression of the rna interference pathway in aedes aegypti interferes with gene silencing and enhances sindbis virus and dengue virus type 2 replication.rna interference (rnai) is the major innate antiviral pathway in aedes aegypti that responds to replicating arboviruses such as dengue virus (denv) and sindbis virus (sinv). on the one hand, the mosquito's rnai machinery is capable of completely eliminating denv2 from ae. aegypti. on the other, transient silencing of key genes of the rnai pathway increases replication of sinv and denv2, allowing the viruses to temporally overcome dose-dependent midgut infection and midgut escape barriers (meb) m ...023331493
biological transmission of arboviruses: reexamination of and new insights into components, mechanisms, and unique traits as well as their evolutionary trends.among animal viruses, arboviruses are unique in that they depend on arthropod vectors for transmission. field research and laboratory investigations related to the three components of this unique mode of transmission, virus, vector, and vertebrate host, have produced an enormous amount of valuable information that may be found in numerous publications. however, despite many reviews on specific viruses, diseases, or interests, a systematic approach to organizing the available information on all f ...016223950
emerging and re-emerging viruses: a global challenge illustrated by chikungunya virus outbreaks.in recent decades, the issue of emerging and re-emerging infectious diseases, especially those related to viruses, has become an increasingly important area of concern in public health. it is of significance to anticipate future epidemics by accumulating knowledge through appropriate research and by monitoring their emergence using indicators from different sources. the objective is to alert and respond effectively in order to reduce the adverse impact on the general populations. most of the eme ...024175207
the role of environmental variables on aedes albopictus biology and chikungunya epidemiology.aedes albopictus is a vector of dengue and chikungunya viruses in the field, along with around 24 additional arboviruses under laboratory conditions. as an invasive mosquito species, ae. albopictus has been expanding in geographical range over the past 20 years, although the poleward extent of mosquito populations is limited by winter temperatures. nonetheless, population densities depend on environmental conditions and since global climate change projections indicate increasing temperatures and ...023916332
protective and pathogenic responses to chikungunya virus infection.chikungunya virus (chikv) is an arbovirus responsible for causing epidemic outbreaks of human disease characterized by painful and often debilitating arthralgia. recently chikv has moved into the caribbean and the americas resulting in massive outbreaks in naïve human populations. given the importance of chikv as an emerging disease, a significant amount of effort has gone into interpreting the virus-host interactions that contribute to protection or virus-induced pathology following chikv infec ...026366337
larval feeding behavior of three co-occurring species of container mosquitoes.interspecific differences in foraging behavior may help to determine whether the outcome of interspecific competition is coexistence or exclusion. mosquitoes in the genus culex are commonly described as foraging primarily by filtering the water column. this behavior contrasts with that of other container-dwelling genera, such as aedes and ochlerotatus, that are thought to forage primarily by browsing on container and detritus surfaces. we compared the feeding behavior of cx. pipiens, ae. albopic ...015707290
identification of mosquito avian-derived blood meals by polymerase chain reaction-heteroduplex analysis.a polymerase chain reaction (pcr) heteroduplex assay (hda) was developed to identify avian derived mosquito blood meals to the species level. the assay used primers amplifying a fragment of the cytochrome b gene from vertebrate but not invertebrate species. in culex tarsalis fed on quail, pcr products derived from the quail cytochrome b gene were detected seven days post-engorgement. in an analysis of wild-caught mosquitoes, 85% of blood-fed mosquitoes produced detectable pcr products. heterodup ...012201598
risk of transmission of viral haemorrhagic fevers and the insecticide susceptibilitystatus of aedes aegypti (linnaeus) in some sites in accra, ghana.dengue is one of the emerging diseases that can mostly only be controlled by vector control since there is no vaccine for the disease. although, dengue has not been reported in ghana, movement of people from neighbouring countries where the disease has been reported can facilitate transmission of the disease.027752187
barriers to success: how baculoviruses establish efficient systemic infections.the mechanisms used by baculoviruses to exit the midgut and cause systemic infection of their insect hosts have been debated for decades. after being ingested, baculoviruses reach the midgut, where several host barriers need to be overcome in order to establish successful infection. one of these barriers is the basal lamina, a presumably virus-impermeable extracellular layer secreted by the epithelial cells lining the midgut and trachea. this review discusses new evidence that demonstrates how t ...021300392
climate, environmental and socio-economic change: weighing up the balance in vector-borne disease transmission.arguably one of the most important effects of climate change is the potential impact on human health. while this is likely to take many forms, the implications for future transmission of vector-borne diseases (vbds), given their ongoing contribution to global disease burden, are both extremely important and highly uncertain. in part, this is owing not only to data limitations and methodological challenges when integrating climate-driven vbd models and climate change projections, but also, perhap ...025688012
arbovirus infections.arbovirus (arthropod-borne virus) infections are increasingly important causes of neurologic disease in the united states through both endemic transmission and travel-associated infections. this article reviews the major arbovirus infections that can cause neurologic disease likely to be encountered in the united states.026633778
chikungunya vaccines in development.chikungunya virus has become a global health threat, spreading to the industrial world of europe and the americas; no treatment or prophylactic vaccine is available. since the late 1960s much effort has been put into the development of a vaccine, and several heterogeneous strategies have already been explored. only two candidates have recently qualified to enter clinical phase ii trials, a chikungunya virus-like particle-based vaccine and a recombinant live attenuated measles virus-vectored vacc ...026554522
genetic linkage map of the edible basidiomycete pleurotus ostreatus.we have constructed a genetic linkage map of the edible basidiomycete pleurotus ostreatus (var. florida). the map is based on the segregation of 178 random amplified polymorphic dna and 23 restriction fragment length polymorphism markers; four hydrophobin, two laccase, and two manganese peroxidase genes; both mating type loci; one isozyme locus (est1); the rrna gene sequence; and a repetitive dna sequence in a population of 80 sibling monokaryons. the map identifies 11 linkage groups correspondi ...011097904
drug-resistant drosophila indicate glutamate-gated chloride channels are targets for the antiparasitics nodulisporic acid and ivermectin.the fruit fly drosophila melanogaster was used to examine the mode of action of the novel insecticide and acaricide nodulisporic acid. flies resistant to nodulisporic acid were selected by stepwise increasing the dose of drug in the culture media. the resistant strain, glc(1), is at least 20-fold resistant to nodulisporic acid and 3-fold cross-resistant to the parasiticide ivermectin, and exhibited decreased brood size, decreased locomotion, and bang sensitivity. binding assays using glc(1) head ...011095718
chorion peroxidase-mediated nadh/o(2) oxidoreduction cooperated by chorion malate dehydrogenase-catalyzed nadh production: a feasible pathway leading to h(2)o(2) formation during chorion hardening in aedes aegypti mosquitoes.a specific chorion peroxidase is present in aedes aegypti and this enzyme is responsible for catalyzing chorion protein cross-linking through dityrosine formation during chorion hardening. peroxidase-mediated dityrosine cross-linking requires h(2)o(2), and this study discusses the possible involvement of the chorion peroxidase in h(2)o(2) formation by mediating nadh/o(2) oxidoreduction during chorion hardening in a. aegypti eggs. our data show that mosquito chorion peroxidase is able to catalyze ...011042391
molecular characterization of the abp1 5'-flanking region in maize and the teosintes.auxin-binding protein 1 subsp. mays (abp1) has been suggested as a receptor mediating auxin-induced cell expansion and differentiation. in maize (zea mays), abp1 is encoded by a single gene, abp1. the tata and caat promoter elements as well as the transcriptional start site were previously identified and all were found to be located within a transposable element (te), tourist-zm11. in this study we report the cloning and characterization of the abp1 5'-flanking region in maize and its wild relat ...010982450
a repressible female-specific lethal genetic system for making transgenic insect strains suitable for a sterile-release program.we have developed a tetracycline-repressible female-specific lethal genetic system in the vinegar fly drosophila melanogaster. one component of the system is the tetracycline-controlled transactivator gene under the control of the fat body and female-specific transcription enhancer from the yolk protein 1 gene. the other component consists of the proapoptotic gene hid under the control of a tetracycline-responsive element. males and females of a strain carrying both components are viable on medi ...010890889
purification and characterization of chorion peroxidase from aedes aegypti eggs.previous study has shown that a peroxidase is present in the mature eggs of aedes aegypti mosquitoes, and the enzyme is involved in the formation of a rigid and insoluble chorion by catalyzing chorion protein crosslinking through dityrosine formation. in this study, chorion peroxidase was solubilized from egg chorion by 1% sds and 2 m urea and purified by various chromatographic techniques. the enzyme has a relative molecular mass of 63,000 as estimated by sds-page. spectral analysis of the enzy ...010871050
