Since the old times, the camels are considered as an influential animal used in different purposes, like transportation and the production of a wool, milk, and meat. They can live and settle in different desert conditions all around the world. Blood parasitic infection of one-humped camels Camelus dromedarius, like Anaplasmosis, Babesiosis, Theileriosis, Trypanosomiasis and Mycoplasmosis, is more common as an infectious diseases transmitted mostly via arthropod ticks and some other ectoparasites. Increase body temperature, progressive  haemolytic  anaemia, digestive disorders, generalized weakness, and emaciation which might terminate by death are the main characteristics of those diseases, However, An epidemiological studies must always conducted to investigate the occurrence, incidence and the prevalence of those diseases around the world. It could be concluded that, The common blood parasitic infection of camels,  could associated with loss of productivity among the affected individuals and might be a zoonotic risk for camel breeders, Clearly, it is of utmost importance to undergo periodical studies to track its prevalence in camels and contact people, The role of veterinary services is also important to advise farmers about the importance of those diseases and to maintain their animals free from ectoparasites by keeping the animals under hygienic conditions. Moreover, Further future programmed control measures will the best and final choice to eliminate these pathologies.
