Preliminary observations on helminth parasite populations of the dromedary in northern Mali.

An abattoir survey on gastrointestinal parasites of the dromedary (Camelus dromedarius) was carried out in March/April 1987 in northern Mali. Parasitological examination of the digestive tract contents of 11 dromedaries revealed that Haemonchus longistipes was the predominant parasite with a prevalence as high as 85.7%. The genera Impalaia, Trichostrongylus, Cooperia, and Oesophagostomum were also recovered, but with a lower level of infection and frequency. The larval stage of the canine cestode Echinococcus granulosus was recorded in a single instance.
