Abstract: | An outbreak of suspected tick paralysis occurred in one-humped camels in Southern Darfur, the Sudan, between latitudes 11-12 degrees N and longitudes 24-25 degrees E, when the camels were herded in tick infested areas. It involved 251 camels of different ages, in ten herds causing 34.3% mortality. The symptoms were incoordination of movements, unsteady gait and recumbency followed by death or recovery. Hyalomma adults and/or Rhipicephalus nymphs and adults were incriminated to be the cause of the disease. Transient paralysis in a guinea pig was produced after experimental feeding of ticks. Removal of the camels from the tick infested areas and treatment against the ectoparasites with Lindane at the concentration of 0.23% contributed to controlling the disease. |
