Mycobacterium is a genus of over 190 species in the phylum Actinomycetota, assigned its own family, Mycobacteriaceae. This genus includes pathogens known to cause serious diseases in mammals, including tuberculosis (M. tuberculosis) and leprosy (M. leprae) in humans.

Nontuberculous mycobacteria (NTM) infections are any illnesses caused by one of the bacteria in the genus (group) Mycobacterium. NTM don’t include Mycobacterium species that cause tuberculosis (M. tuberculosis complex) or leprosy/Hansen’s disease (M. leprae).

2021年12月1日 · A group of bacteria called Mycobacterium avium complex (MAC) causes MAC lung disease. Most people who breathe in or swallow these germs don’t get sick. But some pre-existing conditions can make some people more susceptible to developing a slow-growing infection once MAC enters their airway.

2016年8月11日 · Mycobacteria are a type of germ. There are many different kinds. The most common one causes tuberculosis. Another one causes leprosy. Still others cause infections that are called atypical mycobacterial infections. They …

Mycobacterium, genus of rod-shaped bacteria of the family Mycobacteriaceae (order Actinomycetales), the most important species of which, M. tuberculosis and M. leprae, cause tuberculosis and leprosy, respectively, in humans. M. bovis causes tuberculosis in …

2024年4月15日 · When you see a patient with potential nontuberculous mycobacteria (NTM) disease, carefully evaluate for risks and potential exposures. Signs and symptoms can be vague and are dependent on the site of infection. Both rapid and slow-growing species can cause infections at different body sites.

We investigate the virulence factors, pathogenicity, and diagnostic methods of this bacterium, alongside the clinical symptoms and interpretation of different types of tuberculosis, including cerebral, miliary, nerve, and tubercular tuberculosis.

1. an individual organism of the genus Mycobacterium. 2. a slender, acid-fast microorganism resembling the bacillus that causes tuberculosis.

Mycobacterium are acid-fast bacilli that are slow-growing opportunistic pathogens. Mycobacterium is a genus of Actinobacteria, given its own family, the Mycobacteriaceae. Over 190 species are recognized in this genus 1.

Mycobacteria comprise obligate and opportunistic pathogens that infect a wide range of hosts, including humans, wildlife and livestock. Infections can either be asymptomatic or lead to clinical diseases which vary widely in presentation depending on the species.
