Parasitological studies on abomasal nematodes of Sudanese camels slaughtered at Cairo abattoir with special reference to their seasonally

ABSTRACT

At Cairo abattoir, the abomasa of 141 Sudanese camels were examined for abomasal nematodes, allover a one year period, extended from July 1995 to June 96. The camels were moderately infested [53.2%] with these parasites. Haemonchus spp. represented the bulk of these infestations [48.9%], Trichostrongylus spp. were of low prevalence [10.6%], while Impalaia aegyptiaca was of much lower prevalence [4.3%]. Spring season showed the highest prevalence with the abomasal nematodes [88.9%], while Impalaia aegyptiaca was only prevalent during that season. T. longispicularis was recovered in one case only from camel's abomasa. It was concluded that the problem of parasitic gastritis in Sudanese camels, is mainly a [haemonchosis] problem. The author suggests more future studies about the nature and the epizootology of Impalaia spp. It was concluded also that we must pay attention to the possibility of being camels as reservoirs for the abomasal nematodes transmitting them to the farm animals [sheep, goat, cattle and buffaloes], as T. axei, T. longispicularis and H. contortus, which are recovered from camels in this study, are principally parasities of farm animals. Finally, it was concluded to emphasize on the necessity of drenching anthelmintics to the camels in North Sudan periodically allover the year, especially during spring, as the camel breeders there, usually neglect these measures:
