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
