Abstract
The prevalence and biology of Toxoplasma, Neospora, mange, ticks and gastrointestinal parasites among Saudi Arabian camels (Camelus dromedarius) were investigated. The results of the study revealed that 35.8% (N=190) were Toxoplasma seropositive and 40% (N=169) were Neospora seropositive. Examination of 2449 camels showed that 61.7% (N=1512) were infested with hard ticks of H. dromedarii and H. anatolicum and 15.6% (N=382) were infected with Sarcoptic scabiei. Out of 203 camels 31.5% (N=64) were found to be infested with gastrointestinal parasites. The parasites encountered were Haemonchus, Camelostrogylus, Trichostrongylus, Nematodirs and coccidian spp.
