Feline immunodeficiencyvirus (FIV) infection of domestic cats is one of the most promising animal models for the infection by the human immunodeficiency virus (HIV) which causes acquired immunodeficiency syndrome (AIDS). lnfected cats may develop a disease similar to that observed in AIDS patients, with increased susceptibility to opportunistic infections. Ln this study we used the polymerase chain reaction (PCR) to detect proviral DNA of feline immunodeficiency virus on the blood and tissue samples from cats with a clinical diagnosis of immunodeficiency. The PCR primers were used to amplify the gag gene, which is conserved among different isolates. From 40 samples analyzed, 15 were positive and 4 of them were submitted to hybridization to confirm the specificity of the amplified fragments. These results confirm the presence of FIV in domestic cats in Rio Grande do Sul, Brazil. |
