Detection of porcine parvovirus in domestic pigs in North Kerala

During the period from 2019 to 2021, a total of 45 tissue samples were collected from pigs in Kerala and tested for the presence of porcine parvovirus (PPV) by polymerase chain reaction (PCR) targeting NS1 gene of the virus. Of the samples tested, 4 (8.89 per cent) were found to be positive which was higher than the positivity reported for the virus in Kerala in 2016. Sequence analysis of the amplicons revealed a high degree of similarity to PPV sequences previously reported from India. Biosecurity measures should be adopted to control the spread of viral diseases.
