SEROPREVALENCE OF BRUCELLOSIS IN GOAT AT DINAJPUR, RAJSHAHI AND NILPHAMARI

Abstract

Brucellosis is one of the most important zoonotic diseases of both man _ and animals. It is highly contagious for females who take care of the animals and may cause abortion. Due to limitations of my test it is only used for the diagnosis of qualitative test of brucella. But the test is not capable to determine the quantity how much it has been affected. Brucella abortus antigens are used in the test as both the capture and detector materials. These enablean igen rapid B. brucella Ab kit to identify Brucella abortus antibody in specimens with a high accuracy. The test was very expensive so it was not possible as much as required. I have started my thesis from July to December which was about six months in length. My study areas were three different districts of Bangladesh like Dinajpur, Rajshahi and Nilphamari. The procedure was mainly haemaglutination Inhibition test which was mainly known as B. Brucella anigen test. In case of my research I had shown that when the age is increasing the number of infection is increased. The aged animals are highly susceptible than the lower aged animals .But in the farm level, the presence of organism reduced due to more hygienic practiced. On the other hand ,the presence of brucella organism is higher in local sample due to practice of natural breeding. The percentage of brucella infection was 10% in male and in case of female it was 3.3%. (In table-1). The anigen rapid B. Brucella antibody kit has a letter T & C as "Test line" & "Control line" in the result window are not visible before applying any samples. The control line is used for procedural control. The control line should always appeared if this procedure is performed properly and the test regent's of the control line are working. A purple line will be visible in the result window if there are enough brucella abortus antibodies in the specimen.
