A coprological examination was conducted on 528 camels slaughtered at Maiduguri abattoir to determine the prevalence of gastrointestinal parasites of camels in the semi-arid region of Nigeria. Faecal samples were examined by saturated sodium chloride solution floatation and sedimentation methods. Six genera of nematodes, 2 of cestode and one each of trematodes and coccidian were detected. Haemonchus, Esophagostomum and Trichstrongylus spp were most prevalent. An overall prevalence of 68.9% was recorded in all animals examined. More male (n=319 or 60.4%) than female camels (n=208 or 39.4%) were slaughtered during the period of this investigation. Of the positive samples 219 (582%) had single parasite infection while 145 (41.8%) had multiple infection. More females (82.8%) harboured helminths than male (59.8%). Most male (71.7%) camels had single infection compared to female 47.4%. There was a positive correlation between prevalence of parasite eggs with age of camels; e.g. 65.2, 68.3 and 79.8% for 3-6, 7-10 years and those over 10 years, respectively. Nematodes accounted for 80.8% of the single infection while trematodes and cestodes each accounted for 9.6%. Intestinal protozoa, Eimeria spp as single infection accounted for 1.3% of examined animals.
