Following reports of increased mortality in the small ruminant population of the Sahrawi territories, western Algeria, between January and May 2010, local veterinary authorities suspected an outbreak of peste des petits ruminants (PPR). An investigation was implemented in…

The protective immune response generated by a commercial monovalent inactivated vaccine against bluetongue virus serotype 1 (BTV1) was studied. Five sheep were vaccinated, boost-vaccinated, and then challenged against BTV1 ALG/2006. RT-PCR did not detect viremia at any time…

African swine fever virus (ASFV) causes a haemorrhagic fever in domestic pigs which results in high mortality and has a severe socio-economic impact in affected countries. The disease is endemic in many sub-Saharan countries in Africa and the virus is maintained in an…

Eukaryotic cells make many types of primary and processed RNAs that are found either in specific subcellular compartments or throughout the cells. A complete catalogue of these RNAs is not yet available and their characteristic subcellular localizations are also poorly…

The regulation and control of gene expression in response to differing environmental stimuli is crucial for successful pathogen adaptation and persistence. The regulatory gene vru of Streptococcus uberis encodes a stand-alone response regulator with similarity to the Mga of…

Experimental challenge protocols that consistently reproduce clinical signs of peste des petits ruminants in Alpine goats infected with a tissue culture-passaged peste des petits ruminants virus are described. The protocols can be used to carry out quality-controlled vaccine…

Major histocompatibility complex (MHC) genes play a key role in immunity to infectious pathogens. Their high level of diversity is a functionally important characteristic. In cattle our knowledge of MHC diversity and the functional distinction between genes is limited…

Epizootic hemorrhagic disease virus (EHDV), an arthropod-borne orbivirus (family Reoviridae), is an emerging pathogen of wild and domestic ruminants that is closely related to bluetongue virus (BTV). The present study examines the outcome of an experimental EHDV-7 infection…
