Life-Threatening Cache Valley Virus Infection

New England Journal of Medicine, 1997
The Bunyamwera serogroup (family Bunyaviridae, genus bunyavirus) contains more than 20 serologically cross-reactive viruses, 7 of which have been isolated in North America.1 Cache Valley virus, first isolated in Utah in 1956,2 has been recovered mainly from mosquitoes (genera culiseta, aedes, and anopheles) and occasionally from vertebrates and has the

Isolations of cache valley virus in Texas, 1981

Veterinary Microbiology, 1987
Two strains of the same virus (isolates AR 168 and 7856), were isolated in 1981 from an apparently healthy cow and a sick sheep in TX, U.S.A. These isolates were shown to be members of the Bunyamwera serogroup (family Bunyaviridae, genus Bunyavirus) by complement-fixation tests. Serum dilution-plaque reduction neutralization test results indicated that

Cache Valley virus infection in Texas sheep flocks

Journal of the American Veterinary Medical Association, 1991
Summary Cache Valley virus (cvv), an arbovirus indigenous to the United States, has been implicated as an important teratogenic agent in sheep. The prevalence and distribution of Texas sheep with cvv-specific antibody were investigated. In 1981, 19.1% of 366 sheep located in 22 counties of Texas had antibodies specific for cvv. Of 50 flocks examined in

Cache Valley Virus, a Previously Undescribed Mosquito-Borne Agent

Science, 1959
Cache Valley virus was isolated from Culiseta inornata mosquitoes collected in Utah. The newly isolated agent causes signs of encephalitis in mice inoculated intracerebrally. It has been classified with the Bunyamwera group of anthropod-borne (Arbor) viruses.

Cache Valley virus: an emerging arbovirus of public and veterinary health importance

Journal of Medical Entomology, 2023
AbstractCache Valley virus (CVV) is a mosquito-borne virus in the genus Orthobunyavirus (Bunyavirales: Peribunyaviridae) that has been identified as a teratogen in ruminants causing fetal death and severe malformations during epizootics in the U.S. CVV has recently emerged as a viral pathogen causing severe disease in humans. Despite its emergence as a

Cache Valley Virus

Veterinary Clinics of North America: Food Animal Practice, 1994
Cache Valley Virus (CVV) is a causative agent of a mosquito-borne disease syndrome of sheep and, possibly, of all ruminants, characterized by embryonic and fetal death, stillbirths, and multiple congenital malformations. CVV is endemic in Canada, Mexico, and the United States. Several related Bunyaviruses also may play a role in syndromes of congenital

Cache Valley virus: isolations from mosquitoes in Saskatchewan, 1972–1974

Canadian Journal of Microbiology, 1979
Eighteen isolations of Cache Valley virus (Bunyaviridae) were obtained from a total of 113 694 mosquitoes collected in Saskatchewan during the summers of 1972 to 1974. Most of the isolations were from mosquitoes collected during August. Culiseta inornata, the most abundant mosquito (38% of total collected), had the highest minimum vector-infection ...

Evidence that cache valley virus induces congenital malformations in sheep

Veterinary Microbiology, 1990
An outbreak of congenital abnormalities occurred in sheep at San Angelo, Texas, between December 1986 and February 1987. Of 360 lambs born, 19.2% had arthrogryposis or other musculo-skeletal problems and hydranencephaly (AGH), and the total neonatal loss was 25.6%.

Cache Valley virus: experimental infection in Culiseta inornata

Canadian Journal of Microbiology, 1980
Experiments were conducted to examine the dynamics of Cache Valley virus in Culiseta inornata, the probable chief vector of the virus. Of about 1500 laboratory reared C. inornata exposed to viraemic suckling mice, 72 took a blood meal. A relatively high percentage (93%) of the latter mosquitoes became infected.

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 ...
