Since then, it has become a common therapy for non-muscle invasive bladder cancer.

These infections can involve various anatomic sites and have a range of presentations. Diagnosis may require several testing modalities, and treatment typically involves multiple antimicrobials for a long duration. We report three cases of\n                      <jats:italic toggle=\"yes\">M. bovis<\/jats:italic>\n                      BCG infection following intravesical BCG instillation for the treatment of bladder cancer. The patients are men ranging in age from 71 to 83 years old. One had a ruptured mycotic aneurysm of the aorta, another had a presumed anaphylactic reaction, and the final had a bone marrow infection. Isolation of BCG was achieved through mycobacterial blood culture in two cases and also through mycobacterial culture of bone marrow and hematoma aspirate. Nucleic acid amplification testing for\n                      <jats:italic toggle=\"yes\">Mycobacterium tuberculosis<\/jats:italic>\n                      complex (of which BCG is a member) was utilized in two cases, and histologic examination identified granulomas in one case. Two of the patients received mycobacterial treatment, including rifampin, isoniazid, ethambutol, and linezolid. One patient remains living over 3 years after infection, one died despite treatment, and one died from unrelated causes. These cases highlight the diversity of BCG infection symptoms and sites and the various laboratory testing modalities that can inform diagnosis and treatment.\n                    <\/jats:p>\n
