ABSTRACT
Background:
Goats can be infected by a lentivirus called the caprine arthritis encephalitis virus (CAEV) that causes an infectious disease characterized by a chronic. For replication, the CAEV, integrate as a provirus in the DNA of the host cell genome. By consequence, infection of cells persistent life-long infection of the animal. The CAEV can be found in most body fluids, It has been demonstrated its presence in blood, milk, semen. However, the search for the CAEV in other body fluids besides blood is important to assess possible viral transmission. The aim of this study was to determine whether the presence of proviral DNA sequences in saliva of animals infected.Materials, Methods &Results:
The study was carried out on the farm belonging to the Embrapa Goat and Sheep Research Center, located in the municipality of Sobral, Ceará, Brazil. To assess the oral fluid for the presence of CAEV, samples of saliva from eight infected breeders were collected by suctioning saliva from the oral cavity on the side region of the breeders lower molar teeth using a probe coupled to a plastic 5 mL syringe. And pro-viral DNA was extracted from the samples using NaCl and proteinase K. Two rounds of polymerase chain reaction (nested PCR) were carried out to amplify the final 187 pb fragment of the pro-viral DNA. All the oligonucleotide primers were determined from the gag region...Palavras-chave
