This study was carried out to evaluate the frequency of some occupational infections in veterinarians. The study was performed in 2005. A hundred and eight (80.6%) of 134 veterinary doctors working in Kayseri agreed to be involved in this study. From each of them, a questionnaire consisting of 19 questions was answered by the volunteers and 5 ml venous blood sample was taken for serological analysis. Hydatidosis, toxoplasmosis and brucellosis were evaluated in the samples. All of the volunteers were negative for hydatidosis. Among them, 39.8% were positive for Toxoplasma IgG and 0.9% for Toxoplasma IgM, while Rose Bengal test was positive in 24.1% of them. The tube agglutination test was performed on Rose Bengal positive samples, and in 2 volunteers the titration was determined to be over 1/160. Whereas Rose Bengal test positivity was higher among male volunteers, toxoplasmosis seropositivity was higher among non-surgeons, and brucellosis seropositivity was higher among surgeons. Toxoplasmosis seropositivity rates were found to be increasing with age. Symptoms like fever, sweating, weight loss, and loss of appetite were higher in Rose Bengal positive volunteers. Brucellosis and toxoplasmosis were more frequent in veterinarians so which it will be beneficiary for the health of people working in this profession to be more sensitive about the occupational infections and protection ways from them.
