Prevalence of gastro-intestinal nematode infection in the dromedary camel (Camelus dromedarius) in the Butana plains, Sudan

Abstract

The prevalence and intensity of gastro-intestinal nematode infection in their relation to season and rainfall were investigated from 429 female dromedary camels at Tambul market in the Butana plains (Sudan), during 1985-1986. The investigation revealed a similar seasonal pattern in the prevalence as well as the intensity of egg output. The seasonality is mainly brought about by Haemonchus spp. and Impalaia spp. while Trichostrongylus spp. seem to be present as adults throughout the year. There is a good correlation between high egg counts and rainfall ensuring optimal development of preparasitic stages.
