Abdominal non-tuberculous mycobacterial infection is a rare condition in healthy patients. When it occurs, it leads to the appearance of typical findings of peritoneal involvement, such as thickening of the peritoneal leaflets and the omentum, ascites and enlargement of lymph nodes and of mesenteric nodules. These findings may be misdiagnosed as tumour peritoneal implants. In case of spontaneous regression of the peritoneal involvement and ascites, as well as in the absence of malignancy, the suspicion of infectious disease, including abdominal nontuberculous mycobacterial infection, should be considered.

Unlabelled: is an acid-fast, aerobic, non-motile, and biofilm-forming bacterium. The increasing prevalence of mycobacterial infections makes it necessary to find new methods to combat the resistance of bacteria to conventional antibiotics. is an emerging pathogen that is intrinsically drug resistant due to several factors, including an impermeable cell envelope, drug efflux pumps, target-modifying enzymes, and the ability to form thick, robust biofilms.

Background: Subjects with immune-mediated inflammatory diseases (IMID), such as rheumatoid arthritis, with tuberculosis infection (TBI), have a high probability of progressing to tuberculosis disease (TB). We aim to characterize the impact of IMID on the immune response to (Mtb) in patients with TBI and TB disease.
Methods: We enrolled TBI and TB patients with and without IMID.

We present a rare case of asymptomatic allergic bronchopulmonary aspergillosis (ABPA) concurrent with active pulmonary tuberculosis. Allergic bronchopulmonary aspergillosis is an immunological pulmonary disorder characterized by hypersensitivity to Aspergillus fumigatus, while pulmonary tuberculosis (PTB) is a complex infection caused by Mycobacterium tuberculosis (MTB). The association between pulmonary tuberculosis infections and Aspergillus infections remains a fascinating area of inquiry.

Our qualitative study in Zambia explored the acceptability and preferences for designing TB active case finding (ACF) strategies to reach non-household contacts of people with TB.
Methods: We conducted 56 in-depth interviews with persons with TB ( = 12), TB healthcare workers (HCWs) ( = 10), TB lay HCWs ( = 10), and leaders/owners ( = 12) and attendees ( = 12) of community venue types identified as potential TB transmission locations.

Objectives: Amikacin is crucial for treating Mycobacterium abscessus (Mab) infections, with resistance primarily attributed to rrs gene mutations. The correlation between specific mutations and amikacin susceptibility, along with the associated fitness cost, requires further investigation.
Methods: We isolated spontaneous amikacin-resistant mutants in vitro and identified their mutation sites in the rrs gene via Sanger sequencing, which were then compared with existing reports.
