title: Peste des petits ruminants virus (PPRV) infection; its association with species, seasonal variations and geography.
abstract: The present investigation included a detailed description of the factors directly associated with PPRV infection in Pakistan. A total of 1,056 suspected serum samples were analyzed for the presence of antibodies to PPRV with no history of vaccination against PPR. The samples were collected from sixty two (62) suspected outbreaks from twenty five (25) major regions of the country. Samples were collected from the animals suffering from diarrhea and showing severe respiratory signs. Competitive enzyme linked immuno-sorbant assay (cELISA) was performed to detect the presence of antibodies in the serum against PPRV. Findings suggested that the overall PPR antibody sero-prevalence recorded in sheep was 54.09% as compared to 44.15% in goats. Geography, species, sex, age and season are the major factors associated with PPRV infection. Among various age groups, the animals showed the higher prevalence (67.48% and 52.28% in sheep and goats, respectively) at >2 years as compared with the other age groups. The area-wise highest sero-prevalence was in Sindh province which was 55.10%. It was highest in the plains of Punjab and Sindh province and also in hilly areas (AJK, northern areas and northern Punjab). These findings may be correlated with variations in the sheep and goats husbandry practices within different geographic regions and the topography of different areas. The study also indicated the scenario of antibodies circulation in the population and proving that PPR is now becoming endemic and is one of the major emerging TAD in Pakistan.
