Recommendations for first-line and second-line drug testing and organism group, specific methodologies, and reporting recommendations have been addressed by the Clinical and Laboratory Standards Institute (CLSI) and are important in the selection of appropriate antimicrobial treatment regimens for nontuberculous mycobacteria (NTM) disease. This review also includes recent information on new antimicrobials proposed for the treatment of NTM but not yet addressed by the CLSI and molecular (gene sequencing) methods associated with the detection of antimicrobial resistance of two major therapeutic antimicrobials, clarithromycin and amikacin.

Non-tuberculous mycobacterial skin infection lead to complex and lengthy treatment cycles. Antimicrobial photodynamic therapy (aPDT) is an emerging promising approach for treating infections. This study aims to assess the effects of aPDT using curcumin as a photosensitizer (PS) on non-tuberculous mycobacteria, Mycobacterium abscessus, a subtype that has become common in dermatology in recent years.

The Mycobacterium avium complex (MAC) is a group of closely related nontuberculous mycobacteria that can cause various diseases in humans. In this study, genome sequencing, comprehensive genomic analysis, and antimicrobial susceptibility testing of 66 MAC clinical isolates from King Chulalongkorn Memorial Hospital, Bangkok, Thailand were carried out. Whole-genome average nucleotide identity (ANI) revealed the MAC species distribution, comprising 54 (81.

Non-tuberculous Mycobacteria (NTM) are found extensively in various environments, yet most are non-pathogenic. Only a limited number of these organisms can cause various infections, including those affecting the lungs, skin, and central nervous system, particularly when the host's autoimmune function is compromised. Among these, Non-tuberculous Mycobacteria Pulmonary Diseases (NTM-PD) are the most prevalent.

In the past 20 years infections caused by Mycobacterioides abscessus have become increasingly common in patients with chronic lung conditions. The microorganisms are also resistant to a number of antibiotic classes, making treatment challenging. To begin understanding how the bacterium adapts to the lung environment, pure colonies of M.

Buruli ulcer (BU) a neglected disease induced by the bacterium Mycobacterium ulcerans, predominantly impacts tropical and subtropical areas with its pathophysiology ascribed to the Mycolactone protein. Current antibiotics frequently prove insufficient to manage advanced or chronic ulcers and the rise of drug resistance presents a considerable challenge. This work aims to address these challenges by employing computational methods to identify therapeutic candidates from organic compounds, which may be developed into more effective therapies for Buruli ulcer.
