Abstract
Peste des Petits Ruminant (PPR) is an infectious viral disease of small ruminants caused by PPR virus. Although goat and sheep are the primary hosts of PPR, studies have continuously reported the prevalence of circulating antibodies in large ruminants, which could bring a potential challenge to effectively control and eradicate PPR. In Nepal, seroprevalence of PPRV antibodies in cattle have not been monitored yet. To address this, a total of 255 cattle sera were collected from Rupandehi, Banke, Bara and Chitwan districts of Nepal where outbreak of PPR in small ruminants was reported previously. The sera samples were tested by competitive ELISA and the result indicated the prevalence of 5.88% PPRV antibodies in cattle which indicates the exposure of cattle to PPR virus. To make the disease control program effective, intensive monitoring of both domestic and wild animals is very important.
