Abstract
Semen and peripheral blood mononuclear cells (PBMCs) samples of four naturally infected, four experimentally infected (endangered breeds) and four non-infected bucks (endangered breeds) were evaluated for the presence of CAEV proviral-DNA by nested polymerase chain reaction (n-PCR). Three out of the eight PBMC samples from infected bucks were positive for CAEV-DNA and four out of the eight semen samples were positive for CAEV proviral-DNA. This is the first report describing the presence of CAEV proviral-DNA in semen from seropositive Anglo-Nubian, Moxotó and Canindé bucks, providing useful information towards the design of efficient methods to prevent CAEV dissemination in the endangered goat livestock genetic resources in Brazil.
