| a study of the host selection patterns of the mosquitoes of the kisumu area of kenya. | the results of 12,168 precipitin tests on blood meals of mosquitoes of the kano plain caught by a variety of catching techniques indicate that to gain an accurate overall picture of feeding patterns both the indoor and the outdoor biotope must be sampled. cdc light traps operated inside houses and monkswood type light traps operated under the outside eaves of houses were found to collect larger numbers of blood fed specimens from a wider range of species than battery driven aspirators collecting ... | 1975 | 2997 |
| [the wesselsbron virus, a new arbovirus for madagascar]. | wesselsbron virus, an african arbovirus group flavivirus, has been isolated in 1989 for the first time in madagascar from aedes circumluteolus collected inside primary forest near the village of marovitsika. serological studies in man using haemagglutination inhibition test have permitted to think that wesselsbron virus have circulated quietly in madagascar. the detection of wesselsbron antibodies in lemurs sets the problem of the biological cycle. | 1990 | 1964039 |
| transmission of rift valley fever virus by adult mosquitoes after ingestion of virus as larvae. | we studied the ability of culex pipiens, aedes circumluteolus, and ae. mcintoshi, exposed as larvae to liver tissue from a rift valley fever (rvf) virus-infected hamster, to become infected and transstadially transmit virus to the adult and for the adults to transmit virus by bite to hamsters. after exposure as larvae, 9% (5/54) of adult cx. pipiens and 8% (38/505) of the adult ae. (neomelaniconion) species were infected. all of the infected cx. pipiens and about half of the infected ae. circuml ... | 1990 | 2267972 |
| a bionomic study of adult aedes (neomelaniconion) circumluteolus in northern kwazulu, south africa. | sixteen monthly visits were made to the ndumu game reserve when resting aedes circumluteolus mosquitoes were collected on the ground. the population density reached exceedingly high levels 7 or more days after the usutu and/or pongola rivers inundated their flood plains, and was related mainly to river flooding and far less to local rainfall. during dry months male ae. circumluteolus disappeared while females persisted at very low levels. blood-feeding and ovarian development occurred throughout ... | 1987 | 3504902 |
| vector competence of selected african mosquito (diptera: culicidae) species for rift valley fever virus. | outbreaks of rift valley fever (rvf) in egypt, yemen, and saudi arabia have indicated the potential for this disease to spread from its enzootic areas in sub-saharan africa. because little is known about the potential for most african mosquito species to transmit rvf virus (family bunyaviridae, genus phlebovirus, rvfv), we conducted studies to determine the vector competence of selected african species of mosquitoes for this virus. all eight species tested [aedes palpalis (newstead), aedes mcint ... | 2008 | 18283949 |
| genetic characterization of spondweni and zika viruses and susceptibility of geographically distinct strains of aedes aegypti, aedes albopictus and culex quinquefasciatus (diptera: culicidae) to spondweni virus. | zika virus (zikv) has extended its known geographic distribution to the new world and is now responsible for severe clinical complications in a subset of patients. while substantial genetic and vector susceptibility data exist for zikv, less is known for the closest related flavivirus, spondweni virus (sponv). both zikv and sponv have been known to circulate in africa since the mid-1900s, but neither has been genetically characterized by gene and compared in parallel. furthermore, the susceptibi ... | 2016 | 27783682 |
| full-genome characterisation of orungo, lebombo and changuinola viruses provides evidence for co-evolution of orbiviruses with their arthropod vectors. | the complete genomes of orungo virus (oruv), lebombo virus (lebv) and changuinola virus (cglv) were sequenced, confirming that they each encode 11 distinct proteins (vp1-vp7 and ns1-ns4). phylogenetic analyses of cell-attachment protein 'outer-capsid protein 1' (oc1), show that orbiviruses fall into three large groups, identified as: vp2(oc1), in which oc1 is the 2nd largest protein, including the culicoides transmitted orbiviruses; vp3(oc1), which includes the mosquito transmitted orbiviruses; ... | 2014 | 24475112 |
| molecular characterization of human pathogenic bunyaviruses of the nyando and bwamba/pongola virus groups leads to the genetic identification of mojuí dos campos and kaeng khoi virus. | human infection with bwamba virus (bwav) and the closely related pongola virus (pgav), as well as nyando virus (ndv), are important causes of febrile illness in africa. however, despite seroprevalence studies that indicate high rates of infection in many countries, these viruses remain relatively unknown and unstudied. in addition, a number of unclassified bunyaviruses have been isolated over the years often with uncertain relationships to human disease. | 2014 | 25188437 |
| mosquitoes of western uganda. | the mosquito fauna in many areas of western uganda has never been studied and is currently unknown. one area, bwamba county, has been previously studied and documented but the species lists have not been updated for >40 yr. this paucity of data makes it difficult to determine which arthropod-borne viruses pose a risk to human or animal populations. using co2 baited-light traps, from 2008 through 2010, 67,731 mosquitoes were captured at five locations in western uganda including mweya, sempaya, m ... | 2012 | 23270157 |
