Development of in-house ELISA based on recombinant gag proteins of small ruminant lentiviruses isolated from goats in Thailand.

Small ruminant lentiviruses (SRLVs), are grouped in Retroviridae family, remain a significant loss in the small ruminant husbandry. As a result of unavailability of vaccine and effective treatment, the diagnosis plays a crucial role for the control of SRLV infection. However, the major challenge of diagnosis of SRLV infection is the genetic and antigenic variability of the viruses that can lead to a failure in serological detection.

Seroprevalence of small ruminant lentivirus infection in goats in Thailand.

Small ruminant lentivirus (SRLV), which causes caprine arthritis encephalitis in goats and ovine progressive pneumonia (maedi-visna disease) in sheep, is classified in genus Lentiviruses belonging to Retroviridae family. It persists in infected goats and sheep, which mostly are sub- clinical. A serological survey was conducted to determine the prevalence of small ruminant lentivirus infection in Thai goat population.
