Abstract

Peste des petits ruminants (PPR) is an important transboundary animal disease of small ruminants which causes serious damage to the livelihood and food security of millions of small-scale farmers. PPR is endemic in goats in Bangladesh since 1993. The aim of this study was to determine the seroprevalence of PPR in sheep, cattle, and buffaloes in Bangladesh. A total of 434 blood samples from sheep (n = 100), cattle (n = 190) and buffalo (n = 144) were collected aseptically. Sera were separated and antibody titer was determined using a commercially available c-ELISA kit. The overall seroprevalence was 16% and 3.68% in sheep and cattle, respectively, while buffaloes had a considerably higher seroprevalence of 42.36%. The study suggests that buffaloes are more prone to the PPR virus (PPRV) infection and cattle. This study provides serological evidence of PPRV infection in cattle and buffaloes. These results may warrant further studies to find out the role of large ruminants in transmitting PPRV infection to small ruminants and vice versa and inclusion of all domestic and wild ruminants for regular surveillance program.

Highlights

Peste des petits ruminants (PPR) is an important transboundary animal disease of small ruminants which causes serious damage to the livelihood and food security of millions of small-scale farmers
A total of 434 sera from sheep, cattle, and buffaloes from different areas of Bangladesh were tested by Competitive Enzyme linked Immunosorbant assay (cELISA) using two different ELISA kits
A total of 16 out of 100 sera samples from sheep showed PPR virus (PPRV)-specific antibody collected from Dhaka, Mymensingh, and Netrokona districts with seroprevalence of 6.67% (4/60), 55% (11/20), and 5% (1/20), respectively

Summary

Introduction

Peste des petits ruminants (PPR) is an important transboundary animal disease of small ruminants which causes serious damage to the livelihood and food security of millions of small-scale farmers. Conclusions: This study provides serological evidence of PPRV infection in cattle and buffaloes These results may warrant further studies to find out the role of large ruminants in transmitting PPRV infection to small ruminants and vice versa and inclusion of all domestic and wild ruminants for regular surveillance program. The virus has been reported in many geographic regions and endemic in most of the Saharan and sub-Saharan Africa, Middle East, Indian subcontinent, China, Turkey and recently has been reported in Kazakhstan, Mongolia and Tajikistan [2-3]. Both goats and sheep are susceptible to natural infection, but comparatively goats show increased mortality [4]. In the past few years, PPR antibodies have been detected in a wide range of domestic and wild animal species from different geographic locations [16-18]
