Serologic survey of small ruminants lentiviruses (Maedi-Visna and caprine arthritis-encephalitis) in São Paulo state
AbstractThe aim of this study was to carry out the serological occurrence of Maedi-Visna virus (MVV) and CAE virus (CAEV) in ovines and caprines breeding in São Paulo state. The test to detect MVV and CAEV antibodies was agar gel immunodiffusion (AGID). The detection of antibodies against MVV was 0,3% (4/1235) and against CAEV was 15,1% (30/199). Was carried analysis of risk factors associated with the presence of positive property for CAEV and Maedi-Visna. Variables were selected for both diseases, however, when these variables were used in multivariate logistic regression model were not identified risk factors for the infections. The CAEV infection in the São Paulo state has a wide spread and a high prevalence while MVV has low prevalence. It emphasizes the importance of prevention and control measures to reduce CAEV occurrence and prevent the spread of Maedi-Visna.
