Shankar BP, Patil SS, Narayanaswamy HD, Veeresh H, Sindhoora SC, Gajendragad MR, Prabhudas K., An outbreak of classical swine fever in Karnataka, India, Onl J Vet Res., 24 (2):114-118, 2020. Swine fever by Pestivirus has recently decimated pigs in China (2019). We report an outbrake in swine from Karnataka, India. Symptoms were dullness, anorexia, pyrexia (103-107oC), constipation followed by diarrhea, reddish purple skin, champing jaws, closed eyes with conjunctivitis, apnoea, convulsions, webbling gait and occasional purulent-blood discharge from nostrils and ascites. In blood, we found severe leucopoenia, increased ESR and reduced platelets. Gross lesions were hyperemia, hemorrhage and inflammation. Submaxillary, parotid, retropharyngeal and mesenteric glands showed peripheral congestion with dark red haemorrhagic areas alternating with pale white lymphoid tissue strawberry-like appearance. The salient histological lesions were vascular engorgement, haemorrhages in various tissues and organs and ulceration of the mucosa of the gastro-intestinal tract. These lesions include turkey egg appearance of kidney, infarction and haemorrages on spleen and mulberry fruits like appearance of lymph nodes. This is a first report of classical swine fever in Karnataka. We believe the swine fever had spread to pigs from neighboring states like Kerala, Andrapradesh and Tamilnadu where the disease had been prevalent from 1961.
