ABSTRACT
A Parasitological survey was carried out on 530 camels of different ages, sex and seasons to clear- up the prevalence of gastrointestinal parasites at Shalatin region, Red Sea Governorate, Egypt in period of Jan. 2005 till Dec. 2005. It was found that 72.83% of the examined camels were positives. Out of positive cases 45.66% were harbouring helminthes eggs, 10.94% coccidian oocysts and 16.22% mixed infection. Prevalence of infection with nematodes eggs: Trichostrongylus sp. was the most common parasites detected 35.06%, followed by Oesophagostomum sp., 16.15%, Trichuris sp., 12.19%, Haemonchus sp., 10.67%, Ostertagia sp., 8.84%, Chabertia sp., 8.53%, Nematodirus sp., 4.87% and Strongyloides sp. 1.82%. Prevalence of infection with cestodes eggs: Moniezia sp. 1.82% and coccidian oocysts as Eimeria cameli oocysts 48.61%, Eimeria dromedary oocysts 27.87 and Eimeria Rajathani oocysts 5.6%. Coproculture producing third stage larvae of Trichostrongylus sp., Strongyloides sp., Haemonchus sp., and Ostertagia SP. The prevalence rate of infection was lower in young ages and higher in older ages. Females tend to be highly affected than males. The highest rate of infection was noticed in winter and spring. Therapeutical trials with different anthelmintic drugs were carried out on some infested camels and concluded that Albendazole was the choice drug in treatment of camel's helminthiosis. Conversely, Zanide was less effective
