Abstract

RODRIGUES, Apoliana de Sousa et al. Evaluation of caprine arthritis-encephalitis virus transmission in newborn goat kids. Arq. Inst. Biol. [online]. 2017, vol.84, e0542016.  Epub Feb 01, 2018. ISSN 1808-1657.  https://doi.org/10.1590/1808-1657000542016.

Caprine arthritis encephalitis causes considerable losses in goat production. The main form of the caprine arthritis encephalitis virus transmission is through the ingestion of colostrum or milk from infected females. However, some transmissions cannot be explained in this manner. Therefore, this study aimed to evaluate transplacental transmission of caprine arthritis encephalitis virus. Blood samples were collected from 283 newborn kids of Anglo-Nubian and Saanen breeds born from seropositive and seronegative goats. Samples were collected immediately after birth and analyzed with agarose gel immunodiffusion and western blot. All samples were negative in the agarose gel immunodiffusion. However, the western blot test demonstrated that four kids were born positive for caprine arthritis encephalitis virus. This result indicates that although in a low frequency (1.4%), there is a possibility of transplacental transmission of small ruminant lentivirus.

Keywords : small ruminant lentivirus; agarose gel immunodiffusion; western blot.
