This study was carried out to ascertain the magnitude of occupationally-acquired pulmonary TB PTB among health care workers HCWs at two designated DOTS centers in Ibadan Nigeria. Methods One year descriptive study January-December 2008 was carried out at the University College Hospital and Jericho Chest Hospital both located in Ibadan Nigeria. A pre-tested questionnaire was used to obtain socio-demographic data and other relevant information from the subjects. Three sputum samples were collected from each subject. This was processed using Zeihl-Neelsen Z-N stains. One of the sputum was cultured on modified Ogawa egg medium incubated at 37oC for six weeks. Mycobacterium tuberculosis was confirmed by repeat Z-N staining and biochemical tests. Results A total of 271 subjects 117 males and 154 females were studied. Nine had their sputum positive for acid fast bacilli AFB while six were positive for culture. The culture contamination rate was per cent. Significantly all the six culture positive samples were from males while none was obtained from their female counterparts. About half of the AFB positive samples were from subjects who have spent five years in their working units. Eight AFB positive cases were from 21-50 yr age group while students accounted for seven AFB positive cases.
