ABSTRACT
To estimate Brucella seropositivity among slaughterhouse workers of Lahore district and to elucidate risk factors associated with seropositivity to Brucella. During the year 2008, a cross-sectional study was conducted in four slaughterhouses of Lahore district. A sample of 360 workers was selected from these slaughterhouses through stratified random sampling on proportional basis. Workers were interviewed using a structured questionnaire to obtain risk factor information and their blood samples were collected to be screened for the presence of anti-Brucella IgG using Enzyme Linked Immunosorbent Assay [ELISA] technique. Data management and analysis were performed using SPSS [statistical package for social sciences] version 16. Risk factors associated with seropositivity to anti-Brucella IgG were identified by constructing a logistic regression model. Of the 360 serum samples tested, 21.7% [95% Cl 17.44% - 25.96%] were positive by ELISA test. The logistic regression model identified age [OR 0.96, 95% Cl 0.94-0.99], assistance in parturition of animal [OR 0.47, 95% Cl 0.23-0.96], consuming raw milk [OR 2.25, 95% Cl 1.04-4.87] and handling sheep [OR 0.30, 95% Cl 0.09- 0.92] as risk factors for Brucella seropositivity among slaughterhouse workers of Lahore district. To reduce the burden of brucellosis, a national brucellosis control programme should be initiated with special emphasis on the high risk population of slaughterhouse workers
