| superinfection interference between dengue-2 and dengue-4 viruses in aedes aegypti mosquitoes. | dengue virus consists of four antigenically distinct serotypes (denv 1-4) that are transmitted to humans by aedes aegypti and aedes albopictus mosquitoes. in many dengue-endemic regions, co-circulation of two or more denv serotypes is fairly common increasing the likelihood for exposure of the two vectors to multiple serotypes. we used a model system of denv-2 and denv-4 to investigate how prior exposure of aedes aegypti to one denv serotype affects its susceptibility to another serotype. | 2017 | 28150899 |
| the transovarial transmission in the dynamics of dengue infection: epidemiological implications and thresholds. | the anthropophilic and peridomestic female mosquito aedes aegypti bites humans to suck blood to maturate fertilized eggs, during which dengue virus can be spread between mosquito and human populations. besides this route of transmission, there is a possibility of dengue virus being passed directly to offspring through transovarial (or vertical) transmission. the effects of both horizontal and transovarial transmission routes on the dengue virus transmission are assessed by mathematical modeling. ... | 2017 | 28131789 |
| recent advances in the identification of the host factors involved in dengue virus replication. | dengue virus (denv) belongs to the genus flavivirus of the family flaviviridae and it is primarily transmitted via aedes aegypti and aedes albopictus mosquitoes. the life cycle of denv includes attachment, endocytosis, protein translation, rna synthesis, assembly, egress, and maturation. recent researches have indicated that a variety of host factors, including cellular proteins and micrornas, positively or negatively regulate the denv replication process. this review summarizes the latest findi ... | 2017 | 28124222 |
| aedes aegypti (diptera: culicidae) longevity and differential emergence of dengue fever in two cities in sonora, mexico. | dengue virus, primarily transmitted by the aedes aegypti (l.) mosquito, has rapidly expanded in geographic extent over the past several decades. in some areas, however, dengue fever has not emerged despite established ae. aegypti populations. the reasons for this are unclear and have sometimes been attributed to socio-economic differences. in 2013 we compared ae. aegypti adult density and population age structure between two cities in sonora, mexico: hermosillo, which has regular seasonal dengue ... | 2017 | 28082648 |
| comparison of stable and transient wolbachia infection models in aedes aegypti to block dengue and west nile viruses. | pathogen replication and transmission in wolbachia infected insects are currently studied using three wolbachia infection systems: naturally infected wolbachia hosts, hosts transinfected with wolbachia (stably maintained and inherited infections) and hosts transiently infected with wolbachia. all three systems have been used to test the effect of wolbachia on mosquito transmitted pathogens such as dengue virus (denv), west nile virus (wnv) and plasmodium. from these studies it is becoming increa ... | 2017 | 28052065 |
| optimal control problems of mosquito-borne disease subject to changes in feeding behavior of aedes mosquitoes. | dengue viruses (denv) are transmitted to humans by the bite of aedes mosquitoes. it is known that dengue virus infection in aedes aegypti female mosquitoes makes a change in the feeding behavior of the infected mosquitoes. in this study, using the forces of infection, we incorporated the effect of changes in the feeding behavior of mosquitoes into the standard vector-borne sir-si model. it has been proved that both a single-strain model and a two-strain model exhibit forward bifurcations. moreov ... | 2017 | 28385591 |
| catalase protects aedes aegypti from oxidative stress and increases midgut infection prevalence of dengue but not zika. | digestion of blood in the midgut of aedes aegypti results in the release of pro-oxidant molecules that can be toxic to the mosquito. we hypothesized that after a blood meal, the antioxidant capacity of the midgut is increased to protect cells against oxidative stress. concomitantly, pathogens present in the blood ingested by mosquitoes, such as the arboviruses dengue and zika, also have to overcome the same oxidative challenge, and the antioxidant program induced by the insect is likely to influ ... | 2017 | 28379952 |
| the relationship between entomological indicators of aedes aegypti abundance and dengue virus infection. | routine entomological monitoring data are used to quantify the abundance of ae. aegypti. the public health utility of these indicators is based on the assumption that greater mosquito abundance increases the risk of human denv transmission, and therefore reducing exposure to the vector decreases incidence of infection. entomological survey data from two longitudinal cohort studies in iquitos, peru, linked with 8,153 paired serological samples taken approximately six months apart were analyzed. i ... | 2017 | 28333938 |
