We determined nucleotide sequences of rpoB, hsp65, and sodA in 59 clinical isolates (from 58 patients) of the Mycobacterium abscessus group. Identification to the species level, based on three target genes, was concordant for 44 isolates (25 M. abscessus, 13 Mycobacterium massiliense, and 6 Mycobacterium bolletii isolates) and discordant for 15 isolates which had "interspecific composite patterns." Sequence analysis of five housekeeping genes also showed composite patterns in 8 of these 15 isolates.

Introduction: In response to continued public health emergency of antimicrobial resistance (AMR), a significant key strategy is the discovery of novel mycobacterial efflux-pump inhibitors (EPIs) as potential adjuvants in combination drug therapy. Interest in identifying new chemotypes which could potentially synergize with the existing antibiotics and can be deployed as part of a combination therapy. This strategy could delay the emergence of resistance to existing antibiotics and increase their efficacy against resistant strains of mycobacterial species.

Nontuberculous mycobacteria (NTM) are emerging opportunistic pathogens with limited treatment options due to resistance to multiple antibiotic classes. This study aimed to evaluate the in vitro activity of omadacycline and comparator antibiotics against rapidly growing mycobacteria (RGM) clinical isolates. Minimum inhibitory concentration (MIC) evaluation of RGM clinical isolates was performed by two independent laboratories (EU and Japan).

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.
Mixed Pulmonary Infection, Asthma, and Nephrotic Syndrome in a Patient Diagnosed with Selective IgA Deficiency: A Case Report.

Patients with selective IgA deficiency could have various clinical presentations ranging from asymptomatic to severe respiratory or gastrointestinal tract infection, as well as autoimmune disease and allergic reactions. Selective IgA deficiency is relatively common in Caucasians, but it is rare in the Asian population, meaning it could be easily missed in the clinic. In this study, we report a 26-year-old man with a history of asthma and nephrotic syndrome.
