First report of detection and molecular characterization of porcine parvovirus in domestic and wild pigs in Kerala, India.

ABSTRACT: Porcine parvovirus (PPV) is a DNA virus of the genus Parvovirus of family Parvoviridae. It is the causative agent of many disease problems in pigs such as maternal reproductive failure, stillbirth, mummification, embryonic or fetal death, infertility, abortion and neonatal death. A study was conducted to assess the incidence of the virus in pigs in Kerala State in South India. A total of 38 samples were collected from domestic and wild pigs from different districts of the State. Polymerase chain reaction targeting a 265 bp fragment of the NS1 gene of the virus was carried out. Of the samples tested, 2 (5.26 %) were found to be positive for PPV virus genome, one of which was from a wild pig. One of the positive samples was sequenced and the nucleotide sequence obtained was compared with other sequences of PPV from India and abroad. The results revealed that the sequence had very close similarity to PPV sequences previously reported from India and to that of Chinese isolates. This is the first report of the existence of PPV in domestic and wild pigs in Kerala, India. The study highlights the need to test for the presence of PPV in addition to other infectious agents in diagnosis of cases of reproductive disorders in pigs.
