Abstract

Background: Brucellosis is one of the most prevalent zoonotic diseases. Using serological tests are valid and rapid methods that could be used in the detection of the history of getting brucellosis. Considering that Iran is an endemic country for brucellosis, we aimed to investigate the rate of seroprevalence of brucellosis among livestock and human in Kurdistan province.

Material and method: Serum sampling was performed from 51 slaughterhouse workers, veterinarians, and husbandry workers, along with 260 livestock (80 cattle, 120 sheep, and 60 goats). Rose Bengal plate test (RBPT), and Enzyme-linked immunosorbent assay (ELISA) were used for livestock and the anti-Brucella IgG antibody was evaluated in human participants.

Results: The seroprevalence (based on ELISA assay) in sheep, goats, and cows was 5.8%, 5%, and 1.2%, respectively. Also, the rate of anti-Brucella IgG was 3.9% among human participants.

Discussion: the current study, provided some valuable information on the seroprevalence of brucellosis in animal and human participants from the west of Iran. Considering the effects of brucellosis on causing reproductive disorders, including abortion, placental retention, andendometritis controlling the infection could have a significant impact on terms of economy.
