Incidence of brucellosis in Sri Lanka: an overview.

Infection by Brucella abortus seems to be a major cause of abortions among cattle and buffaloes in Sri Lanka. The incidence of this disease is more prominent among the animals in the Dry zone of the country raised under extensive management systems. The present low incidence of this disease and the small size of the country may facilitate launching of an effective disease control scheme. The milk ring test (MRT) has proven to be usable in testing milk for the infection at farm level. An ELISA technique could be employed to test the seroprevalence of infection among MRT-positive animals. A program to purchase the diseased animals by the state for slaughter, and a countrywide vaccination program with B. abortus strain RB51 would enable the country's livestock industry to eventually eradicate this disease.
