SEROLOGICAL EVIDENCE OF PORCINE RESPIRATORY CORONAVIRUS IN A OUTBREAK OF PORCINE RESPIRATORY COMPLEX IN VENEZUELA

摘要

The swine viral respiratory primary pathogens capable of inducing clinical disease and lesions by themselves are porcine respiratory reproductive syndrome (PRRS), swine influenza (SI), porcine respiratory coronavirus (PRCV) and Aujeszky disease (AD).The Porcine Respiratory Corononavirus (PRCV),appeared in Europe in 1983 and in USA in 1989. This virus is antigenically similar to TGEV and conventional serologic test do not distinguish between the two virus. In order to be able to continue serologicalsurveys of swine TGE-PRCV specific antibodies, competitive ELISA based on TGEV specific monoclonal antibodies were developed. At this moment it has been identified in Venezuela viral activity for PRRS, AD and TGE, but non PRCV.
