Seroprevalence of Q fever in Goats in the Sudan

Abstract

Aim: The survey was carried out to detect anti- C. burnetii antibodies in goat's sera samples in eight States in the Sudan during September 2010-July 2011. Materials and Methods: In a preliminary study, four hundred and sixty caprine sera samples collected from eight States in the Sudan were screened for anti- Coxiella burnetii (the causative agent of Q fever) antibodies using a commercial indirect ELISA (iELISA) kit. Results: The results showed an overall prevalence rate 24.22% of Q fever antibodies. The prevalence rate of antibodies ranged from 6.7% in Kassala to 40% in South Darfur. The prevalence rates were highest in South Darfur (40%) and South Kordofan (34.7%), moderate in El Gazira (29.7%), Khartoum (29.1%), the Northern (24%) and the River Nile (20.2%) States. It was lowest in the White Nile (7.5%) and Kassala (6.7%) States. Conclusion: It could be concluded that Q fever is prevalent in goats in the Sudan. Therefore, further epizootiological investigations on Q fever in other farm animals and man at the country level is important to monitor and determine the magnitude of Q fever infection in order to estimate its economic impact on animal industry and its public health hazard in the Sudan. In addition, the impact of Q fever among shepherds should be studied.
