SERO-PREVALENCE STUDY OF BRUCELLOSIS IN CATTLE AND CONTACT HUMAN IN MYMENSINGH DISTRICT

Abstract

A cross-sectional survey was conducted to determine the seroprevalence of brucellosis in cattle and in contact human in Veterinary Clinic and Dairy Farm of Bangladesh Agricultural University (BAU) from June 2007 to November 2007. A total of 200 sera samples from cattle and 50 sera samples from human were collected from BAU Veterinary Clinic and USDA funded Red Chittagong cattle project at BAU Dairy Farm. Questionnaire based data on risk factors were collected both in cattle and in contact human. Sera were separated from blood samples and tested with the Rose Bengal Test (RBT) and Standard Tube Agglutination Test (STAT) parallely. Multiple logistic regression was used to identify risk factors of brucellosis both in cattle and in contact human using SPSS^®. The overall seroprevalence of brucellosis in cattle and in contact human were found 4.5% and 6% respectively. Statistically insignificant higher seroprevalence of brucellosis was found in cattle aged above 4 years and in human aged above 30 years, in Red Chittagong cattle of BAU dairy farm, in female of cattle and in male of human, in cattle with grazing, in pregnant cows, in animal owner and in human with smoking.
