ABSTRACT:
The prevalence of lentivirus infection of small ruminants (LVPR) was determined in samples of serum from goats and sheep in slaughterhouses from ten districts of Pernambuco State. The serological test was used in agarose gel immunodiffusion (AGID) with antigen caprine arthritis and encephalitis virus (CAE)/Maedi Visna virus. Among the 369 blood serum samples of goats examined, seven (1.89%) (0.8-3.9%) were seropositive, and among the 383 sheep samples examined, just one (0.26%) (0.0-1.4%) was infected. The seven seropositive goats came from public slaughterhouses from Gravatá (n=2), Sertânia (n=4) and Timbaúba (n=1), and the soropositive sheep was from a public slaughterhouse of Serra Talhada. The soroprevalence of LVPR infection in small ruminants from Pernambuco's slaughterhouses, of 1.06% (8/752), is considered low.
