Microscopic and Molecular Detection of Camel Piroplasmosis in Gadarif State, Sudan

Abstract

The socioeconomic importance of camels (Camelus dromedarius) could not be neglected in the Sudan. The present study was planned to confirm the presence of piroplasmosis in camels from the Eastern region of the Sudan (Gedarif State) using microscopical (blood film) and molecular technique (PCR). A total of 55 camels of different sexes (34 females and 21 males) were sampled from four localities of the state between January 2011 and January 2012. The prevalence rates using parasitological and molecular examinations were 43.6% and 74.5%, respectively. The prevalence rates significantly vary between the localities (p=0.011) but not between the different sexes (p=0.515). PCR technique showed higher sensitivity than microscopy. The present paper was to be the first report investigating camel piroplasmosis using both parasitological and molecular methods in the Eastern region of the Sudan. Further studies in the phylogenetic sequencing are to be continued for parasite speciation. Moreover, studies on the clinical and economic consequences of camel piroplasmosis are recommended.
