Abstract EN

The study was carried out in four Awassi sheep research stations that belong to the General Commission for Scientific Agricultural Research in various regions of Syria during 2009 and 2010, in order to determine the prevalence of Coenurus cerebralis.

The total number of examined animals was 5044 heads.

The mean prevalence of the disease was 1.96%, the highest prevalence was at Bir Alhashem research station 4.1% followed by Gasr Alhalabat, Wadi Elazeeb, and Alshola (3.6%, 1.1 and 0.7%) respectively.

Both sexes were affected with higher prevalence in females 60.6% than males 39.4 %.
