The caprine arthritis encephalitis is a multisystemic infectious disease caused by a Lentivirus may affect animals at all ages and sex. The major symptoms are leukoencephalomyelitis, cronical interstitial pneumonia, arthritis and hardening interstitial mastitis. It was described that mammary glands from infected animals had a gradual non inflammatory diffuse nodular hardening, and also decreased milk production and abnormal physical-chemical milk parameters. The detection on milk samples by PCR and nested-PCR techniques are characterized as methods with high specificity and sensibility that provides fast results. The techniques are able to identify nucleic acids on samples with no living virus. In this study, 72 milk samples from infected and seroreagent to IDAG test animals were evaluated. DNA generation with specifics primers, PCR and nested-PCR was conducted for individual amplification from a genomic fragment corresponding to the Pol gene. Fourteen samples (19, 4%) presented positive by PCR at 600 bp length bands and 16 samples (22, 2%) by nested-PCR at 278 bp length bands. Our results show the adequacy for detecting pro viral DNA on milk samples and may be used as a complementary means of Caprine Arthritis and Encephalitis diagnosis.Additional Files
