ABSTRACT
Peste des petits ruminants virus (PPRV) causes an economically important disease of small ruminants that causes extensive livestock losses across areas where it is endemic. A serological survey on the prevalence of antibodies to PPRV was carried out in sheep and goats of Jatoi and surrounding areas in Muzaffargarh districts South Punjab of Pakistan. A total of 965 serum samples were collected from sheep and goat’s farms from January to December 2015 with no history of vaccination. Haemagglutination inhibition (HI) test was performed using PPRV antigen to determine antibody titres level. The overall prevalence of antibodies to PPRV in goats and sheep were 66.22% (521 samples) and 65.76% (444 samples), respectively. Sero-prevalence of anti-PPRV antibodies was found higher in adults (69.14% with GMT 17.91) than in young (62.47% with GMT 12.85). Furthermore, seasonal seropositivity seasons was recorded and sero-prevalence during summer was found to be higher (72.84% with GMT 20.18) than other seasons with an overall PPRV seroprevalence of 66.01%. Moreover, related to sex discrimination, 69.80:63.83% (GMT 14.83:15.92) antibody titre has been screened in female and male, respectively. So, based on the sero-prevalence, the evaluation of intrinsic (age groups and sex) and extrinsic factors (season fluctuation) clearly indicated the occurrence of previous outbreaks of PPR virus due to persistency of virus in endemic regions.
