Studies on the prevalence of antibodies for Peste des Petits Ruminants [PPR] and Rinderpest [RP] virus in sheep and goats sera

ABSTRACT

A total of 182 sera samples were collected from two sheep breeds [mixed and Barki sheep] as well as goats raised under arid conditions and examined by serum neutralization test [SNT] for neutralizing antibodies of PPR and RP viruses. The results showed that at 1 4 serum dilution, 29.41% of mixed breed sheep, 29.82% of Barki sheep and 29.82% of goats sera contained antibodies to PPR virus, while 2.9%, 12.28% of the two sheep breeds, respectively, and 7% of goats sera had antibodies to RP virus. It could be concluded that the prevalence of neutralizing antibodies to PPR virus is equal in sheep and goats. There is no significant difference between the two sheep breeds tested for PPR virus antibodies, but RP virus antibodies is higher in the sera of Barki sheep than that of the mixed breed sheep and the antibodies for PPR virus in the two sheep breeds are more prevalent than in goats
