Abstract

In this study 400 blood samples were collected from apparently healthy animals (100 Cows, 100 Buffaloes, 100 Sheep and 100 Pigs) for screening of serogical prevalence of Y. enterocolitica agglutinins. 172 ((43%) strongly displayed antibodies against Y. enterocolitica seovars 0:3 and / or 0:9. Among these Yersinia positive sera, 164 (41%) were indeed against Y. enterocolitica after elimination of 8 sera samples which demonstrated cross-reactivity with B. abortus. The rather high antibody prevalence was seen in buffaloes and sheep 46% each. While in pigs and cows was 43% and 37% respectively. It is believed that this is the first report on serological features of Y. enterocolitica in animals in Egypt.
