Article Abstract
Drug resistance (DR) in is the main problem in fighting tuberculosis (TB). This pathogenic bacterium has several types of DR implementation: acquired and intrinsic DR. Recent studies have shown that exposure to various antibiotics activates multiple genes, including genes responsible for intrinsic DR. To date, there is evidence of the acquisition of resistance at concentrations well below the standard MICs. In this study, we aimed to investigate the mechanism of intrinsic drug cross-resistance induction by subinhibitory concentrations of antibiotics. We showed that pretreatment of with low doses of antibiotics (kanamycin and ofloxacin) induced drug resistance. This effect may be caused by a change in the expression of transcriptional regulators of the mycobacterial resistome, in particular the main transcriptional regulator .

Black mouth disease (BMD) serves as the principal bacterial affliction of the cultivated sea urchin Strongylocentrotus intermedius, commonly breaking out in spring and winter. In January 2024 (winter), two predominant bacterial strains (SIBMPM04 and SIBMIT01) closely associated with BMD were isolated from the peristomial membrane and intestine of diseased S. intermedius from a farming area in the Yellow Sea of China.

Background: The aim of this study was to determine differences in susceptibility of exoU and exoS Pseudomonas aeruginosa to multi-purpose disinfecting solutions (MPDS) and antibiotics and their association with disinfectant resistance genes.
Methods: A total of 16 exoU and 24 exoS P. aeruginosa keratitis isolates were tested for susceptibility against four multipurpose disinfecting solutions (OPTI-FREE PureMoist, Acuvue RevitaLens, Biotrue, and Renu Advanced Formula) using minimum inhibitory (MIC) and minimum bactericidal (MBC) concentrations.

To compare the diagnostic yield of various bioinformatics tools for predicting Mycobacterium tuberculosis drug resistance. A systematic review of PubMed, Embase, Scopus, Web of Science, CINAHL and the Cochrane Library was performed to identify studies reporting the effectiveness of bioinformatic tools for predicting resistance to anti-tuberculosis (TB) drugs. Data were collected and pooled using random-effects meta-analysis and Bayesian network meta-analysis (NMA).
