Your healthcare provider may perform additional tests to rule out other clinical conditions to arrive at a definitive diagnosis. Also, not having a risk factor does not mean that an individual will not get the condition. Mycobacterial Infections, Atypical Definition Atypical mycobacterial infections are infections caused by several types of mycobacteria similar to the germ that causes tuberculosis. As a result, the clinical manifestations of NTM lung disease are often similar to those of the underlying disease. Article menu . The author examined computed tomographic (CT) scans of the chest from 40 patients with cultures positive for atypical mycobacteria. Serial scans were obtained in 10 patients and showed new areas of bronchiectasis and progression of existing bronchiectasis, suggesting that the bronchiectasis was not a preexisting condition but resulted from infection.

M. kansasii infections are endemic in cities with infected tap water. The identification of multifocal coexistent bronchiectasis, air-space disease, and nodules at CT should raise the possibility of atypical mycobacterial lung disease, even in an otherwise healthy patient. Marras TK, Wagnetz U, Jamieson FB, Patsios DA. In children, lymphadenitis * is the most common type of MOT T infection, whereas lung infections, which occur less often in children, are the most common in adults.

These germs are commonly found throughout the environment. In a patient with chronic symptoms, infection is less likely, although certain infections, such as atypical mycobacterial and fungal organisms, may have a chronic course, as do diseases with a predisposition to chronic infection, such as cystic fibrosis or immune deficiency. Atypical mycobacterial infection has been described in the medical literature since the mid 1950s. The prognosis is good for a majority of the affected individuals, with prompt diagnosis and appropriate treatment.

Jeong YJ, Lee KS, Koh WJ, Han J, Kim TS, Kwon OJ. They aren't "typical" because they don't cause tuberculosis. Females with these characteristics are especially at risk for infection, A weakened immune system from certain illnesses or drugs, Having esophageal disorders, which may result in spillage of the gastric contents into the lung leading to lung infections, Exposure to environments where atypical mycobacteria are found. Most exposures and infections by these organisms do not cause disease, which usually requires a defect in local or systemic host defenses; the frail elderly and immunocompromised people are at the highest risk. As in the case of patients with lung infiltrates on chest X‐ray, in whom atypical infection is high on the list of differential diagnoses, cases of unusual or treatment‐resistant skin lesions should raise the possibility of atypical mycobacterial infection. NLM Fungi in Bronchiectasis: A Concise Review. NTM are found in the soil, air, and water, so you can get an infection from swimming, gardening, or breathing air with NTM. Mycobacterium avium-intracellulare infection (MAI) is an atypical mycobacterial infection, i.e. Most children affected are typically healthy (i.e., not immunocompromised). Validation of a model for predicting smear-positive active pulmonary tuberculosis in patients with initial acid-fast bacilli smear-negative sputum. There are also nontuberculous (NTM) mycobacteria, ubiquitous in soil, water, food, on the surfaces of many plants and within buildings, particularly within water pipes.
