Abstract

 
 

Objective: The current study aimed to assess BTB as a possible risk factor for human TB in the rural community of North Eastern and Western parts of Ethiopia.

 Method: A case-control design conducted among cattle owning households with TB and without TB. Comparative cervical intradermal test using purified protein derivatives were used to test cattle.  Reading of the reaction was done 72 + 4hrs after antigen injection. Based on the skin test reaction measurement, cattle categorized as negative, doubtful and positive. Questionnaires were used to collect factors.

Results:  Thirty five with TB and 105 households without TB households participated in this study. Of which 49.3% and 61.4% were having the habit of drinking raw milk and eating uncooked meat, respectively. About 70.7% knew chance of disease transmission from animals to humans. Among the TB house holds 31.43% were used house sharing with their cattle.  Of the attendants approximately 38% were shared utensil. Based on >2mms as a cutoff value 23.6% an overall apparent bovine tuberculosis (BTB) and 48.6% apparent BTB in households with TB were recorded. The odds for households having bovine TB in their cattle to get tuberculosis was more than 8 times (95% CI; 2.82-24.60) higher to those owned by households without TB.

Conclusion: Bovine TB has been seen as an exposure to human pulmonary TB occurrence. A separate house for cattle should be constructed to minimize the fear of cross infections and further study regarding the possible infection of cattle with M. tuberculosis is suggested.
