ABSTRACT
Peste des petits ruminant’s virus (PPRV) causes a highly contagious disease in both domestic, wild ruminants and camels. Sera from non-vaccinated sheep (n=683), goats (n=624) and camels (n=155) of all ages and sexes were collected in a cross-sectional study in Hail, Bagaa, Shenan and Ghazalah. Saudi Arabia. The seroprevalece was determined by NP-epitopes based competitive ELISA. The overall prevalence was 59.9%, goats had a significantly higher sero-prevalence of 75.3% compared to 59.4% obtained from sheep, whereas camels were seronegative. The prevalence of PPR was increasing from 27.9% in 2011 to 77.3% in 2016. Seropositivity was higher in wet seasons (60.9 to 61.4%) to 56.7% in dry hot season. Species, year and location appeared to be having significant effect (p<0.01) on the frequency of circulating antibodies in the study. The results highlight that PPR in Hail is alarming and warrants mass vaccination along with appropriate control measures.
