Disseminated infections have been commonly documented in the immunocompromised and patients who undergo treatment for non-muscle invasive bladder cancer with the Bacillus Calmette-Guerin vaccine; however, it was unique to our patient's case that she had no record of receiving vaccination in her native country, was immunocompetent, and had exposure to bovine livestock before immigrating to the United States. A 57-year-old woman with no significant medical history presented with complaints of abdominal pains and yellowing of her skin. Laboratory workup was consistent with cholestatic hepatitis. One month prior to presentation, she underwent biopsy and culture of an unspecified bladder mass, which turned out to be positive for . All antituberculosis medications were discontinued, without improvement of her symptoms and hepatic function tests. Subsequent liver biopsy showed the presence of granulomas with acid-fast bacilli; hence, disseminated infection was highly suspected. Multiple sputum cultures and quantiferon tests were negative, and other diagnostic tests were unremarkable. Initiation of appropriate antibiotics resulted in marked symptomatic improvement and gradual normalization of hepatic function parameters. Disseminated mycobacterial infection may present differently in patients; however, it is important to note that the source of primary infection may vary. Prompt diagnosis and treatment of these pathogens may lead to improved outcomes.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Unlabelled: Non tuberculous mycobacteria (NTM) are important opportunistic infection in patients with AIDS.
Aim: To present 4 cases of disseminated infections by NTM in patients with AIDS.
Results: These cases were associated with prolonged symptoms of fever, weight loss, diarrhea or cough, with hepatosplenomegaly, anemia and thrombocytopenia.

Interferon-gamma (IFN-γ) autoantibody syndrome is an emerging clinical entity that has been associated with disseminated non-tuberculous mycobacterial infection (dNTM) particularly in healthy young people, a population not previously thought to be at particular risk. A 29-year-old South-East Asian man presented with several weeks of fever, cough, lymphadenopathy, and constitutional symptoms while working on an international cargo ship, deteriorating rapidly with a sepsis-like syndrome. Eventually lymph node and sputum cultures revealed a diagnosis of dNTM infection with growth of both Mycobacterium persicum and Mycobacterium abscessus.

Mycobacterial infections of the cardiovascular system are rare and only a few reports provide detailed pathological information. This report presented a rare case of asymptomatic myocardial mycobacterial infection identified at autopsy. The patient died from pulmonary thromboembolism.

Worldwide, a variety of mycobacterial species have been associated with skin lesions in dogs and cats. Lesions may result from systemic dissemination or local cutaneous inoculation. Only infections with Mycobacterium tuberculosis complex organisms have the potential to be transmitted from companion animals to humans, but even then, zoonotic risk is considered low.
