Summary: This study characterized AFM-2 and AFM-3 metallo-beta-lactamase from clinical Pseudomonas aeruginosa isolates. The results showed that these enzymes exhibited beta-lactamase activity comparable to NDM-1, and the co-carriage of bla(AFM) and bla(KPC) genes rendered P. aeruginosa resistant to antipseudomonal beta-lactams. Furthermore, the association of bla(AFM) genes with translocatable genetic elements and plasmids highlighted their potential for dissemination.

Summary: This study aimed to analyze the resistance mechanisms of ceftolozane-tazobactam and ceftazidime-avibactam in multidrug-resistant or extensively drug-resistant P. aeruginosa isolates. The findings revealed that most of the resistant isolates were recovered after treatment with ceftolozane-tazobactam or ceftazidime-avibactam. Chromosomal mutations and specific gene substitutions were identified as the main resistance mechanisms. The study emphasized the potential selection of MDR/XDR P. aeruginosa strains producing certain variants or metallo-beta-lactamases by cephalosporin/beta-lactamase inhibitors, and encouraged judicious use of these agents.

Summary: The study evaluated the effectiveness of a semi-automated antimicrobial susceptibility testing system in detecting ceftazidime-avibactam resistance in carbapenem-resistant, metallo-beta-lactamase-producing bacteria. The system showed good performance in detecting susceptibility to ceftazidime-avibactam, providing a reliable method for identifying phenotypic resistance in these bacteria.

Summary: In this study, the researchers optimized 1H-imidazole-2-carboxylic acid (ICA) derivatives guided by X-ray structure to develop inhibitor 55 that can interact ingeniously with metallo-beta-lactamases (MBLs) and reverse carbapenem resistance. In experiments, inhibitor 55 demonstrated potent antibacterial activity and showed good pharmacokinetics and safety in vivo.

Summary: Resistance to beta-lactam antibiotics is a growing concern due to the spread of serine-beta-lactamases (SBLs) and metallo-beta-lactamases (MBLs), which efficiently break down beta-lactam antibiotics. While inhibitors for SBLs have been successful in clinical use, there are currently no inhibitors for MBLs. MBLs are particularly worrisome as they can break down most beta-lactam antibiotics and are rapidly disseminating across bacterial species worldwide.

Summary: Treatment options for Pseudomonas aeruginosa infections are limited, and Imipenem/relebactam (I/R) plus aztreonam (ATM) may be an option. This study evaluated the effect of this combination on different strains of P. aeruginosa and found that it exhibited synergy at physiological concentrations. However, further research is needed to understand the dynamic concentration effect of this combination.

Summary: The study investigated the mechanisms behind the in vivo switch in resistance phenotype of P. aeruginosa after ceftazidime-avibactam treatment. It was found that a single SNP difference can lead to a change in resistance profile, reverting a carbapenemase phenotype back into an ESBL phenotype. Through genetic analysis, it was discovered that certain mutations can alter the resistance patterns of bacteria in vivo.

Summary: Metallo-beta-lactamase (MBL)-producing Gram-negative bacteria are increasing globally, with few effective agents against them. Taniborbactam is a newly developed bicyclic boronate beta-lactamase inhibitor that shows promising activity against MBL-producing isolates when used in combination with cefepime or meropenem.

Summary: This nationwide study aimed to investigate the molecular characteristics, resistance mechanisms, genetic context, and clonal relationship of metallo-beta-lactamase (MBL)-producing Pseudomonas aeruginosa in Serbia. The study found that 320 out of 5334 isolates collected from 2018 to 2021 were identified as P. aeruginosa, and 43.1% of carbapenem-resistant isolates carried the bla(NDM-1) gene. The study also revealed the presence of high-risk clones ST235 and ST654, which are important vectors of MBL and ESBL and are associated with multidrug resistance.

Summary: UTI, caused by UPEC, is a common bacterial infectious disease with significant morbidity. The genetic structure and virulence factors of UPEC vary between clinical and commensal isolates, with B2 and D phylogenetic groups strongly associated with UPEC. Understanding the epidemiology and characteristics of UPEC isolates in different regions is crucial for controlling UTI. Interfering with intestinal colonization, particularly in pathogenic clonal lineages like B2, may help reduce the burden of UTI.

Summary: Avian pathogenic Escherichia coli (APEC) is a significant bacterial pathogen causing avian colibacillosis with high economic losses in the poultry industry. This study investigated and compared virulence-associated genes (VAGs), antimicrobial resistance (AMR), and phylogenetic groups distribution between APEC and avian fecal E. coli (AFEC) strains. Most strains were multi-drug resistant (MDR) and carried three or more VAGs, with higher virulence scores in pathogenic strains.

Three best producers of biosurfactants were selected from 15 isolated bacteria based on related tests. These bacteria exhibited tolerance to salinity and were classified as resistant and very resistant. The bacterial strains identified as Bacillus sp., Bacillus toyonensis, Bacillus cereus, and Bacillus tropicus showed appreciable laccase, peroxidase, CMCase activity, and biosurfactant production potentials.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
