Development of monoclonal antibodies to Rift Valley Fever Virus and their application in antigen detection and indirect immunofluorescence.

Rift Valley fever virus is a mosquito-borne virus which is associated with acute hemorrhagic fever leading to large outbreaks among ruminants and humans in Africa and the Arabian Peninsula. RVFV circulates between mosquitoes, ruminants, camels and humans, which requires divergent amplification and maintenance strategies that have not been fully explored on the cellular and molecular level. We therefore assessed monoclonal antibodies for their applicability to monitor the expression pattern and kinetics of viral proteins in different RVFV infected cell species.

Seroprevalence of Rift Valley fever virus in livestock during inter-epidemic period in Egypt, 2014/15.

Background: Rift Valley fever virus (RVFV) caused several outbreaks throughout the African continent and the Arabian Peninsula posing significant threat to human and animal health. In Egypt the first and most important Rift Valley fever epidemic occurred during 1977/78 with a multitude of infected humans and huge economic losses in livestock. After this major outbreak, RVF epidemics re-occurred in irregular intervals between 1993 and 2003.

Rift Valley fever virus infections in Egyptian cattle and their prevention.

Rift Valley fever virus (RVFV) causes consistently severe outbreaks with high public health impacts and economic losses in livestock in many African countries and has also been introduced to Saudi Arabia and Yemen. Egypt with its four large outbreaks in the last 40 years represents the northernmost endemic area of RVFV. The purpose of this study was to provide an insight into the current anti-RVFV antibody status in immunized as well as non-immunized dairy cattle from the Nile Delta of Egypt.

Vaccination of alpacas against Rift Valley fever virus: Safety, immunogenicity and pathogenicity of MP-12 vaccine.

Rift Valley fever (RVF) is an emerging zoonosis of major public health concern in Africa and Arabia. Previous outbreaks attributed camelids a significant role in the epidemiology of Rift Valley fever virus (RVFV), making them an important target species for vaccination. Using three alpacas as model-organisms for dromedary camels, the safety, immunogenicity and pathogenicity of the MP-12 vaccine were evaluated in this study.

A competitive ELISA for species-independent detection of Crimean-Congo hemorrhagic fever virus specific antibodies.

Crimean-Congo hemorrhagic fever virus (CCHFV) circulates in many countries of Asia, Africa, and Europe. CCHFV can cause a severe hemorrhagic fever in humans with case-fatality rates of up to 80%. CCHF is considered to be one of the major emerging diseases spreading to and within Europe.
