| Biopsy from a peritoneal granuloma showed caseation necrosis and acid-fast bacilli. |
| Acid-fast bacilli were numerous, both intracellularly in histiocytes and extracellularly in necrotic areas. |
| Results of a Mantoux test and sputum test for acid-fast bacilli were negative. |
| All the patients had bacilli sensitive to streptomycin, isoniazid and rifampicin initially. |
| The role of macrophage apoptosis in containing the growth of the bacilli is also discussed. |
| Cultures of right and left lung tissues were obtained for bacteria, acid-fast bacilli, and fungi. |
