Mycobacteroides abscessus (formerly Mycobacterium abscessus[1]) is a species of rapidly growing, multidrug-resistant, nontuberculous mycobacteria (NTM) that is a common soil and water contaminant. Although M. abscessus most commonly causes chronic lung infection and skin and soft tissue infection (SSTI), it can also cause infection in almost ...
Human disease is believed to be acquired from environmental exposures. Unlike tuberculosis and leprosy, animal-to-human or human-to-human transmission of NTM rarely occurs. [9] NTM diseases have been seen in most industrialized countries, where incidence rates vary from 1.0 to 1.8 cases per 100,000 persons.
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. The Greek prefix myco- means 'fungus', alluding to this genus' mold -like ...
Mycobacteroides is a genus of Gram-Positive rod-shaped bacteria in the family Mycobacteriaceae from the order Mycobacteriales. [1]Members of Mycobacteroides were demarcated from the larger genus Mycobacterium in 2018 by Gupta et al. based on evidence from various phylogenetic trees constructed based on conserved genome sequences, comparative genomic analyses and average amino acid identity ...
Veterinary medicine. Paratuberculosis is a contagious, chronic and sometimes fatal infection that primarily affects the small intestine of ruminants. [1] It is caused by the bacterium Mycobacterium avium subspecies paratuberculosis. Infections normally affect ruminants (mammals that have four compartments of their stomachs, of which the rumen ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
The Mycobacterium tuberculosis complex (MTC or MTBC) is a genetically related group of Mycobacterium species that can cause tuberculosis in humans or other animals. It includes: Mycobacterium tuberculosis. Mycobacterium africanum. Mycobacterium orygis [1] Mycobacterium bovis and the Bacillus Calmette–Guérin strain. Mycobacterium microti.
Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. [1][2] First discovered in 1882 by Robert Koch, M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid.
