Mosquito Feeding-Induced Enhancement of Cache Valley Virus (Bunyaviridae) Infection in Mice

Journal of Medical Entomology, 1998
Cache-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 ...

Seroepidemiology of California and Bunyamwera serogroup (Bunyaviridae) virus infections in native populations of Alaska.

The American journal of tropical medicine and hygiene, 1999
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 L-A9 cells and Aedes albopictus cells infected with Marituba (Bunyaviridae) virus

Virus Research, 1987
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.

Experimental Infection of Six Species of Ixodid Ticks with Dugbe Virus (Family Bunyaviridae, Genus Nairovirus)

The American Journal of Tropical Medicine and Hygiene, 1989
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.

Selective inhibition of protein synthesis by hypertonic medium in Marituba (Bunyaviridae) virus-infected L-A9 cells

Journal of Virological Methods, 1987
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.

Spontaneous Flight Activity of Aedes trivittatus (Diptera: Culicidae) Infected with Trivittatus Virus (Bunyaviridae: California Serogroup)

Journal of Medical Entomology, 1987
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

Infections by viruses of the families Bunyaviridae and Filoviridae.

Revue scientifique et technique (International Office of Epizootics), 2002
Rift Valley fever is the most important bunyaviral disease of animals in Africa. The virus, transmitted by mosquitoes, causes abortions and mortality in young animals in addition to haemorrhagic fevers in humans. Although vaccines against this virus are available, the uses of these vaccines are limited because of deleterious effects or incomplete ...

ASSOCIATION BETWEEN MOVEMENT AND SIN NOMBRE VIRUS (BUNYAVIRIDAE: HANTAVIRUS) INFECTION IN NORTH AMERICAN DEERMICE (PEROMYSCUS MANICULATUS) IN COLORADO

Journal of Wildlife Diseases, 2013
Capture data from long-term, mark-recapture studies were used to evaluate movements of North American deermice (Peromyscus maniculatus) on mark-recapture webs in Colorado with respect to Sin Nombre virus (SNV) infection status, age, sex, and trapping site.

Serological evidence of infection with California serogroup viruses (family Bunyaviridae) in residents of Long Hua, suburb of Shanghai, People's Republic of China

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1984
Sera from 126 residents of Long Hua, a suburb of Shanghai, in the People's Republic of China, were studied. Sera were tested for haemagglutination inhibiting antibodies to alphavirus (eastern equine encephalitis, western equine encephalitis), flavivirus (St.

[Serological evidence of hanta virus infection (Bunyaviridae: Hantavirus) in rodents from the Sucre Department in Colombia].

Revista de salud publica (Bogota, Colombia), 2015
The main goal of this research was to determine the frequency of hantavirus-specific antibodies in rodents from the municipality of San Marcos in the Sucre department of Colombia.144 rodents were captured in San Marcos' urban and rural areas using Sherman traps between December 2007 and July 2009.
