Objective: Nigeria has a high burden of tuberculosis but the drug resistant situation was previously unknown. This report evaluates the first line drug resistance and associated factors among chronic tuberculosis cases from the tuberculosis control programme in South south and South east zones of Nigeria. Methods: Descriptive study of chronic tuberculosis patients consecutively referred from March 2003 to December 2005. Information collected by indepth interview of patients and tuberculosis microscopy, culture and sensitivity of patients sputum. Results: Of 82 patients infected with M. tuberculosis strains, 57(64.0%) were males while their mean age was 38.0 13.2 years. Fifty nine (72.0%) patients had multidrug-resistance tuberculosis with 35(42.7%) resistant to rifampicin, isoniazid, ethambutol, streptomycin while 14(17.1%) had poly-drug resistance and one patient had monoresistance to isoniazid. Within and outside the national control programme, drug therapy was inappropriate (69.5-81.7%) and treatment poorly supervised (26.8-39.0%). Factors associated with multidrug resistance were a male age less than 45years and Category 1 treatment in a private health facility. Conclusion: The multidrug resistance burden in chronic tuberculosis cases is very high in southern Nigeria and should be urgently and adequately controlled in the interest of public health.
