In Vitro Susceptibility Testing of Omadacycline against Nontuberculous Mycobacteria (NTM) Antimicrob Agents Chemother. 2020 Dec 7;AAC.01947-20. doi: 10.1128/AAC.01947-20. Online ahead of print Omadacycline is a novel aminomethylcycline antimicrobial agent and a member of the tetracycline class of drugs. Its mechanism of action is similar to that of other tetracyclines, i.e. binding to the bacterial ribosome, resulting in inhibition of protein synthesis
Mycobacterium avium complex (MAC) and Mycobacterium abscessus complex are the most frequently encountered NTM, and oral treatment options are extremely limited for these pathogens, especially for the M. abscessus complex. In this study, the in vitro potency of omadacycline, a new tetracycline derivative, was tested against 111 isolates of NTM Omadacycline is an aminomethylcycline antimicrobial approved by the US Food and Drug Administration in 2018 for community-acquired bacterial pneumonia and acute bacterial skin and skin structure infections Arikayce (amikacin liposome inhalation suspension) for Mycobacterium avium complex lung disease; Xofluza (baloxavir marboxil) for acute uncomplicated influenza; and Nuzyra (omadacycline) for community-acquired bacterial pneumonia and/or acute bacterial skin and skin structure infections

MAC includes two closely related species, Mycobacterium avium and Mycobacterium intracellulare, and may also be referred to as MAI.MAC is one of a large group of nontuberculous mycobacteria (NTM), and the most common cause of NTM lung disease in the U.S Mycobacterium avium complex (MAC) infection is caused by bacteria and is not an inherited condition. To become infected with MAC bacteria and get sick, a person must first be exposed to one of the associated types of bacteria. There have been a few reports of families with more than one family member with a MAC infection Mycobacterium avium Complex (MAC) The organism. M. avium complex or MAC (also referred to as MAI) includes at least two mycobacterial species, M. avium and M. intracellulare. These two species cannot be differentiated on the basis of traditional physical and biochemical tests

Evolving Nomenclature. Mycobacterium abscessus (MABS), a rapidly growing non-tuberculous mycobacterium (NTM) (Howard and Byrd, 2000) is an emerging pathogen worldwide.Perhaps the earliest case of MABS was reported in 1951 and described infection which occurred in the setting of traumatic knee injury. This infection was characterized by subcutaneous, abscess-like lesions with a peripherally. . The drug is an inhaled treatment taken through a nebulizer.
