چکیده

The study was undertaken to determine transmission of mycobacterium tuberculosis within the prison environment. in total,168 aba federal prison inmates in nigeria were evaluated for tuberculosis (tb) by sputum-smear microscopy and sputum culture,simultaneously,and for hiv status by serology. they were subsequently followed up for one year for fresh mycobacterium-associated infection by tuberculin skin testing or for development of tb and for hiv infection or aids. ninety-one (54.2%) of the 168 prison inmates had infection due to mycobacterium,and three (3.3%) of them were sputum-smear- and culture-positive while 41 (24.4%),including one (2.4%) with concomitant tb,were hiv-infected. in a one-year follow-up study,11 (19.3%) of 57 tuberculin skin test (tst)- and hiv-negative inmates became tst-positive and one (1.8%) hiv-positive,eight (13.8%) of the 58 tst-positive but hiv-negative inmates developed tb,and one (1.7%) became hiv-infected: six (24.0%) of 25 tst- and hiv-positive inmates developed tb while five (33.3%) of 15 tst-negative but hiv-positive inmates became tst-positive,and one (6.7%) progressed to aids. the duration of imprisonment did not influence the rates of infection,and the transmission of mycobacterium tuberculosis did not necessarily require sharing a cell with a tb case. © international centre for diarrhoeal disease research,bangladesh.
