Arboviruses from the families Flaviviridae, Togaviridae, and Bunyaviridae are suspected to cause widespread morbidity in sub-Saharan African populations, but little research been done to document the burden and distribution of these pathogens. We tested serum samples from 256 Cameroonian adults from nine rural villages for the presence of Dengue-2 (DEN-

Cache Valley virus (CVV) and Potosi virus (POTV) are two closely related mosquito-borne viruses (Bunyaviridae: Bunyamwera group) that appear to circulate in several regions of the United States, especially the Midwest. We determined the prevalence of specific neutralizing antibodies to both viruses in Indiana white-tailed deer and conducted infection ...

Mosquito Feeding-Induced Enhancement of Cache Valley Virus (Bunyaviridae) Infection in Mice
Journal of Medical Entomology, 1998Cache-Valley (CV) virus, an arthropod-borne bunyavirus, recently has emerged as a significant veterinary pathogen causing infertility and congenital malformations in North American ruminants. To investigate the role of vector feeding on CV infection, adult mice were injected subcutaneously with CV, CV and vector thorax extract (a source of vector ...

The vector potential of each of 6 species of colonized North American and African ixodid ticks was assessed by intracoelomic inoculation with Dugbe virus (IbAr 1792, 14th passage in suckling mouse brain) and viral titers were monitored after selected incubation periods.

Spontaneous flight activity of Aedes trivittatus (Coquillett) infected with trivittatus (TVT) virus was evaluated by using an acoustic activity chamber system on days 11 through 17 postinfection. Peak flight activity occurred at the beginning of the photophase, with a second activity period at the beginning of the scotophase. Circadian activity pattern

In November 1984 a case of Crimean-Congo haemorrhagic fever (CCHF) occurred in a worker who became ill after slaughtering ostriches (Struthio camelus) on a farm near Oudtshoorn in the Cape province of South Africa. The diagnosis was confirmed by isolation of CCHF virus from the patient's serum and by demonstration of a specific antibody response.

This study investigated the geographic distribution and prevalence of antibodies to California and Bunyamwera serogroup viruses in Native populations of Alaska, and demographic and ecologic risk factors associated with exposure. Sera (n = 1,635) from 18 communities were screened using an ELISA.

The surface charge of Marituba virus infected L-A9 cells and Aedes albopictus cells was estimated by direct measurement of their electrophoretic mobilities. Uninfected L-A9 cells and A. albopictus cells have mean electrophoretic mobilities of -1.083 microns/s X cm/V and -1.019 microns/s X cm/V, respectively.

Elevation of the NaCl concentration in the growth medium of L-A9 cells caused an inhibition of the protein synthesis accompanied by a complete breakdown of polyribosomes. However, a complete recovery of the rate of protein synthesis was observed when isotonicity was restored.
