Field investigations of brucellosis in cattle and small ruminants in Syria, 1990-1996

The authors present the epidemiological status of brucellosis in cattle and small ruminants in Syria from 1990 to 1996, based on laboratory findings at the Brucellosis Centre, Damascus. Initial investigations using the Rose Bengal plate test, the complement fixation test and a miniaturised variant of the slow agglutination test were conducted throughout the country in 1990 and 1991, revealing an overall herd seroprevalence rate of 3.14% in cattle herds and 2.94% in small ruminant flocks. Although partially biased by previous vaccination of young female cattle with S19 vaccine, these figures indicate that brucellosis in cattle is widespread, particularly in the urban governorates (provinces) of Damascus, Aleppo and Suwaydah. Brucellosis seroprevalence in sheep and goats was relatively high in the governorates of Damascus, Aleppo and Dara'a. The results of a second series of investigations, performed between 1992 and 1996, show that herd seroprevalence in cattle decreased steadily from 17.48% in 1992, to 2.59% in 1996, in the Government-owned farms, while seroprevalence increased in the private sector during the same period.
