Studies on Neurotropic Rift Valley Fever Virus:
The neurotropic strain of Rift Valley fever virus produces encephalitis when inoculated intracerebrally in lambs. Subcutaneous inoculation into sheep and lambs does not cause illness. Immunity against the pantropic strain follows the subcutaneous injection of neurotropic virus in sheep and lambs. Two species of monkey, Macaca mulatta, the rhesus monkey, and M. irus, the crab-eating macacque, ar...
متن کاملImmunogenicity of combination DNA vaccines for Rift Valley fever virus, tick-borne encephalitis virus, Hantaan virus, and Crimean Congo hemorrhagic fever virus.
DNA vaccines for Rift Valley fever virus (RVFV), Crimean Congo hemorrhagic fever virus (CCHFV), tick-borne encephalitis virus (TBEV), and Hantaan virus (HTNV), were tested in mice alone or in various combinations. The bunyavirus vaccines (RVFV, CCHFV, and HTNV) expressed Gn and Gc genes, and the flavivirus vaccine (TBEV) expressed the preM and E genes. All vaccines were delivered by gene gun. T...
متن کاملWidespread Rift Valley Fever Emergence in Senegal in 2013–2014
Rift Valley fever (RVF), which caused epizootics and epidemics among human and livestock populations, occurred in Senegal in 2013-2014. A multidisciplinary field investigation was carried out in 3 regions of Senegal. We found 11 confirmed human cases of Rift Valley fever, including severe cases with encephalitis and retinitis, 1 pool of mosquito (Aedes ochraceus), and 52 animals tested positive...
متن کاملNew vectors of Rift Valley fever in West Africa.
After an outbreak of Rift Valley fever in Southern Mauritania in 1987, entomologic studies were conducted in a bordering region in Sénégal from 1991 to 1996 to identify the sylvatic vectors of Rift Valley fever virus. The virus was isolated from the floodwater mosquitoes Aedes vexans and Ae. ochraceus. In 1974 and 1983, the virus had been isolated from Ae. dalzieli. Although these vectors diffe...
متن کاملTowards a better understanding of Rift Valley fever epidemiology in the south-west of the Indian Ocean
Rift Valley fever virus (Phlebovirus, Bunyaviridae) is an arbovirus causing intermittent epizootics and sporadic epidemics primarily in East Africa. Infection causes severe and often fatal illness in young sheep, goats and cattle. Domestic animals and humans can be contaminated by close contact with infectious tissues or through mosquito infectious bites. Rift Valley fever virus was historicall...
متن کاملTemperature-sensitive mutations for live-attenuated Rift Valley fever vaccines: implications from other RNA viruses
Rift Valley fever (RVF) is a mosquito-borne zoonotic disease endemic to the African continent. RVF is characterized by high rate of abortions in ruminants and hemorrhagic fever, encephalitis, or blindness in humans. RVF is caused by the Rift Valley fever virus (RVFV: genus Phlebovirus, family Bunyaviridae). Vaccination is the only known effective strategy to prevent the disease, but there are n...
