A panel of six imidazo[1,2-a]pyridine-3-carboxamides (IAPs) were shown to have low-micromolar activity against Mycobacterium avium strains. Compound ND-10885 (compound 2) showed significant activity in the lung, spleen, and liver in a mouse M. avium infection model. A combined regimen consisting of ND-10885 (compound 2) and rifampin was additive in its anti-M. avium activity in the lung. Our data indicate that IAPs represent a new class of antibiotics that are active against M. avium and could potentially serve as an effective addition to a combined treatment regimen.

Objectives: Nontuberculous mycobacteria (NTM) are increasingly recognized opportunistic pathogens found ubiquitously in the environment. The presence of multiple NTM species at the site of disease complicates diagnosis and treatment.
Case And Management: A 40-year-old patient who tested positive for HIV, with an absolute clusters of differentiation 4+ T-cell count of 3 cells/µl and cryptococcaemia, presented with hemoptysis, productive cough, and weight loss.
Background: Due to its increasing prevalence and suboptimal treatment, non-tuberculous mycobacterial (NTM) infection is an emerging problem in patients with cystic fibrosis (CF). Detailed description of regional NTM prevalence and distribution, and identification of predictors of NTM acquisition in CF are essential to optimise treatment and surveillance guidelines.
Methods: A retrospective, multi-center analysis was conducted between the years 2020 and 2022 on data from 232 adult patients registered in the Hungarian CF Registry in 2022.

Unlabelled: The complex (MAC) is a common causative agent causing nontuberculous mycobacterial (NTM) pulmonary disease worldwide. Whole-genome sequencing was performed on a total of 203 retrospective MAC isolates from respiratory specimens. Phylogenomic analysis identified eight subspecies and species.

Paratuberculosis, a chronic wasting disease affecting domestic and wild ruminants worldwide, is caused by Mycobacterium avium subsp. paratuberculosis (MAP). Various diagnostic tests exist for detecting MAP infection; however, none of them possess perfect accuracy to be qualified as a reference standard test, particularly due to their notably low sensitivity.

Objective: The global prevalence of nontuberculous mycobacterial pulmonary disease (NTM-PD) has been steadily increasing. A few small retrospective studies have reported a poor prognosis associated with chronic pulmonary aspergillosis (CPA) as a complication of NTM-PD. Furthermore, the prognostic impact of CPA may have been inadequately assessed due to differences in background factors.
