Abstract

         We conducted a study to find out the concurrent occurrence of porcine circovirus 2 (PCV2) and porcine parvovirus(PPV) in pigs affected with reproductive disorders and post weaning multisystemic wasting syndrome along with the genetic characterization of the identified agents. Out of 150 samples which were screened by PCR, 57 were stillbirths and mummified, 41 were pre-weaned piglets and 52 were post-weaned animals. The co-infection of viruses was detected in 9 out of 150 pigs (6%) by conventional PCR. The pathological lesions in the co infected cases were more severe, indicating a synergistic action between the PCV2 and PPV. BLAST analysis of VP2 gene sequence of two isolates of parvovirus named IVRI- 312-2015 and IVRI-350-2015 showed maximum identity (98-99%) with different isolates of China, Hungary, Romania and Germany. In the present study, we report cases of both reproductive failures and postweaning multi systemic wasting syndrome (PMWS), due to concurrent infection with PCV2 and PPV in Indian pigs.
