Conclusion: This infection causes respiratory illness in birds, pigs, and humans, especially in immunocompromised people. The virus weakens a person’s immune system making them less able to fight off germs, including TB and NTM. There are also nontuberculous (NTM) mycobacteria, ubiquitous in soil, water, food, on the surfaces of many plants and within buildings, particularly within water pipes. A retrospective review of 219 transplant procedures (60 single lung transplants and 159 double lung transplants) in 210 patients was conducted. today = new Date(); document.write("Copyright © ", today.getFullYear()); Moore EH(1). Symptoms may include a cough that produces sputum or blood, fever, fatigue, weight loss, and night sweats. At least four of five patients had nontuberculous mycobacterium (one showed acid fast bacilli and granuloma on a biopsy specimen that was not sent for culture). BAL samples were processed routinely for mycobacterium. Mycobacterium abscessus [mī–kō–bak–tair–ee–yum ab–ses–sus] (also called M. abscessus) is a bacterium distantly related to the ones that cause tuberculosis and Hansen’s Disease (Leprosy).It is part of a group of environmental mycobacteria and is found in water, soil, and dust. Once in the lungs, the pathophysiology of these infections is believed to be relatively NTM infections persist because mucus gets trapped in the lungs. Ocular mycobacterial infection represents an important form of extra pulmonary infection which encompasses tubercular (TB) as well as nontubercular mycobacterial (NTM) diseases in and around the eye.
