The purpose of this study regarding isoniazid-epiroprim's association applied to antituberculosis chemotherapy, carried through murine model, initiated into Institut Pasteur of Côte d'Ivoire and worked out at Institut Pasteur of Paris was to evaluate the epiroprim's effect alone and associated with isoniazid on Mycobacterium tuberculosis. Sixteen mouses (lineage C57Bl/6) were inoculated by venous way with 10(5) viable bacillus (strain H37Rv) suspended in 500 microliters sterile physiological aqueous solution and were shared out into 4 sets. Fifteen days later the sets have been submitted or not to a daily treatment by gavage during three weeks (epiroprim, isoniazid, isoniazid plus epiroprim). The mouses were euthanasied, spleen and lung were removed from each animal. The titres of determined bacillus into those organs prove that isoniazid and epiroprim associated seem more efficacious than the isoniazid monotherapy for mouses pulmonary tuberculosis. Bacillus obtained are sensitive to isoniazid.
