Predicting Distribution of Aedes Aegypti and Culex Pipiens Complex, Potential Vectors of Rift Valley Fever Virus in Relation to Disease Epidemics in East Africa. [PDF]

, 2013
The East African region has experienced several Rift Valley fever (RVF) outbreaks since the 1930s. The objective of this study was to identify distributions of potential disease vectors in relation to disease epidemics.

Characterisation of immune responses and protective efficacy in mice after immunisation with Rift Valley Fever virus cDNA constructs

Virology Journal, 2009
Background Affecting both livestock and humans, Rift Valley Fever is considered as one of the most important viral zoonoses in Africa. However, no licensed vaccines or effective treatments are yet available for human use.

Exploratory Space-Time Analyses of Rift Valley Fever in South Africa in 2008-2011 [PDF]

, 2012
Background: Rift Valley fever (RVF) is a zoonotic arbovirosis for which the primary hosts are domestic livestock (cattle, sheep and goats). RVF was first described in South Africa in 1950-1951.

Arbovirus Prevalence in Mosquitoes, Kenya

Emerging Infectious Diseases, 2011
Few studies have investigated the many mosquito species that harbor arboviruses in Kenya. During the 2006–2007 Rift Valley fever outbreak in North Eastern Province, Kenya, exophilic mosquitoes were collected from homesteads within 2 affected areas ...

Genome Analysis of Rift Valley Fever Virus, Mayotte

Emerging Infectious Diseases, 2012
As further confirmation of a first human case of Rift Valley fever in 2007 in Comoros, we isolated Rift Valley fever virus in suspected human cases. These viruses are genetically closely linked to the 2006–2007 isolates from Kenya.

Generation and characterization of a recombinant Rift Valley fever virus expressing a V5 epitope-tagged RNA-dependent RNA polymerase [PDF]

, 2011
The viral RNA-dependent RNA polymerase (RdRp; L protein) of Rift Valley fever virus (RVFV; family Bunyaviridae) is a 238 kDa protein that is crucial for the life cycle of the virus, as it catalyses both transcription of viral mRNAs and replication of the

Factors Affecting on Production of Clostridium novyi type (B) Alpha Toxin

Journal of Applied Veterinary Sciences, 2022
Clostridium novyi type B is an anaerobic bacterium that causes black disease (infectious necrotic hepatitis). The alpha toxin is considered as a major virulence factor. The disease has been controlled using toxoid vaccines.
