Abstract

Prevention, control and eradication of brucellosis in areas where the disease is endemic requires sufficient epidemiological information to apply policies. The present study was conducted with the aim of epidemiological investigation of brucellosis among the ruminant population of Lorestan province. In this cross-sectional descriptive study, all studies related to brucellosis in livestock were analyzed in Lorestan province. The results obtained from this study show that brucellosis has a high prevalence (22%) in three ruminant species (including cows, sheep and goats) of Lorestan province. The highest prevalence of brucellosis in sheep, goat, and cow milk was determined to be 25.6%, 23.5%, and 21.3%, respectively. Brucella abortus is the predominant species in milk obtained from ruminants in Lorestan province. Rev. 1 vaccine strain is excreted to a high extent (7.5%) in sheep and goats' milk. In general, unpasteurized milk is introduced as a threat to public health in Lorestan province. More extensive studies should be conducted, and existing methods of controlling and eradicating brucellosis should be modified.
