ABSTRACT: Tuberculosis is Zoonotic disease and
infected animals continue to spread the disease to other animals and humans by
excreting the germs in milk, meat, feces, and respiratory droplets, this study
used bPPD (Bovine purified protein derivative) to observe TST (Tuberculin skin
test) reactivity in the Sheep population in the Sadar and Parbatipur Upazilas
of Dinajpur District. The research conducted from January to June of 2018.
There is no history for sheep tuberculosis in the study area. Overall, 5
percent (7/140) of 140 sheep were positive, 15% (21/140) were doubtful, and 80%
(112/140) were negative based on sex, age, breed, and body condition score,
while lactation stage and reproduction status prevalence was 6.4 percent, 14.9
percent, and 78.7% positive, doubtful, and negative, respectively. Our findings
suggest the presence of a skin test reaction response when employing the bPPD
reagent, but this needs to be validated by pathological and serological
techniques. Nevertheless, my preliminary investigation suggests that abattoirs
must implement effective control systems and raise public awareness.
