Description Brucellosis in small ruminants is caused by Brucella melitensis and appears to have established on many sheep or goat farms in the country where losses occur in the form of abortion, premature or stillbirth, birth of weak lamb from females and epididymo-orchitis in males, year after year. Vaccination of small ruminants against brucellosis to control the disease is not practiced in India. A sheep breeding farm in Haryana was established in 1969, and brucellosis at this farm is prevalent for more than 3 decades. An epidemiological study of more than 10 years revealed continuous presence of the disease at the farm. Culling of positive animals did not help in controlling the disease and reducing the losses. A strategy of vaccination of serologically negative population with Brucella melitensis Rev.1 vaccine coupled with segregation and culling of positive animals was implemented to control the disease at the farm. Vaccination of all the serologically negative animals was carried out in 2007 with simultaneous culling of positive population. More than 3 years have passed but the cases of abortion in ewes and epididymo-orchitis in rams have not been recorded in animals subsequent to vaccination, which otherwise were noticed every year at the farm prior to vaccination. This study could serve as an effective model for many sheep or goat farms in the country where the disease is endemic.
