The porcine kobuvirus (PKV) is suspected to cause large outbreaks of diarrhea and dehydration along with vomiting in suckling piglets with a high morbidity rate. Despite of its global importance only few studies are available on the pathology of PKV. The present study was conducted with the objective to investigate the pathology of PKV in naturally infected Indian pigs. A total of 41 intestinal content and tissue samples from dead pigs were collected from post-mortem facility of, ICAR-IVRI during April 2019 to July 2020 and subjected to histopathological examination and molecular investigation. The 3D region of PKV was amplified using RT-PCR and 3D gene based Genetic characterization of Indian isolate of the PKV was done. A total of six out of 41 necropsied piglets were found positive for the PKV with the thickening and clouding of brain meninges, congestion of brain, pneumonia along with catarrhal and haemorrhagic enteritis as common gross lesions. Mild to moderate perivascular cuffing, congestion of meningeal and cerebral vessels, focal gliosis and neuronophagia along with mild to severe interstitial pneumonia and emphysema was observed as common microscopic findings. Intestinal mucosa revealed severe inflammatory changes along with sloughing of villi. This study reported the first pathological investigation of PKV from Indian pigs. In addition, the molecular characterization revealed maximum identity of 91 - 93% with Chinese strain of PKV, FJ459905 and Indian isolate of PKV, MH394282. Further explorative surveillance along with epidemiological studies is highly warranted to find out the real impact of the PKV on Indian pigs.
