Background and Objectives: Brucellosis is one of the most important zoonosis and economic diseases in many areas of the world. The aim of this study was to estimate the seroprevalence of brucellosis in rural cattle, sheep and goats population of Bushehr province.

 Methods: This cross-sectional survey was conducted in 2012-2014. For cattle population a total of 118 villages and 891 cattle and for sheep and goats population a total of 202 villages, 526 flocks and 3064 sheep and 7182 goats were included. Samples were examined with Rose Bengal screening test and then positive samples were tested with 2-mercaptoethanol and wright.

 Among cattle population, 28 out of 118 villages (20.34%, CI 95%: 13.94%-28.73%) and 20 out of 891 cattle (3.36%, CI 95%:2.28-4.77%) were seropositive. Additionally in sheep and goats population, 89 out of 202 villages (44.06%, CI 95%: 37.10%-51.20%), 142 out of 526 flocks (27%, CI 95%: 23.25%-31%) and 335 out of 10246 sheep and goats (3.27%, CI 95%: 2.93%-3.63%) were seropositive.

Results: The prevalence of brucellosis at individual level of all animals in 2012 was 3.53% and was significantly higher than in 2013 that was 2.59% (P=0.02). Totally in 3 years, the prevalence of brucellosis in sheep (3.88%) was significantly higher than goats (3%) (P = 0.02) and the prevalence in female (3.52%) was significantly higher than male animals (1.58%)(P <0.001).

Conclusion: Due to the reduction of the prevalence of brucellosis, the test and slaughter policy together with the vaccination of the susceptible animals could further reduce and control the spread of disease in the animal population.
