Opportunistic Co-infections in Pulmonary Tuberculosis

Pulmonary tuberculosis is a pathology caused by <i>Mycobacterium</i> <i>tuberculosis</i> or Koch's bacillus. Some patients with tuberculosis present co-infection with <i>Streptococcus</i> genus bacteria. Nevertheless, this co-infection is very rare, mainly in HIV patients. Here, we report the case of a 38-year-old male patient, previously healthy, who presented with subacute cough and fever, in whom two uncommon <i>Streptococcus</i> species were identified. Because symptoms persisted despite directed antibiotic therapy, bronchofibroscopy was performed, and <i>M.</i> <i>tuberculosis</i> was identified in the lavage. After diagnosis, the patient was referred to the Center for Pneumological Diseases for continued treatment.
