    Abstract Objectives: This study aimed to investigate the in vitro susceptibility and β-lactamase-encoding genes of Pseudomonas aeruginosa (P. aeruginosa) isolates with discrepant resistance to various carbapenems.
    Methods: Data on P. aeruginosa isolates were obtained from the Antimicrobial Testing Leadership and Surveillance program from 2012-2021. Minimum inhibitory concentrations of P. aeruginosa isolates were determined using the broth microdilution method. β-lactamase-encoding genes were identified using multiplex polymerase chain reaction assays.
    Results: Among the P. aeruginosa isolates that were tested, the percentages of isolates resistant to imipenem, meropenem and doripenem were 26.9% (14 447 of 53 617), 20.5% (14 098 of 68 897) and 17.5% (3660 of 20 946), respectively. Imipenem-resistant P. aeruginosa isolates were more susceptible to all tested antimicrobial agents (except colistin) than the meropenem-resistant or doripenem-resistant P. aeruginosa isolates. Carbapenemase genes were detected in 14.3% (2020 of 14 098) of meropenem-resistant P. aeruginosa isolates. Imipenem-resistant meropenem-susceptible P. aeruginosa isolates had higher susceptibility profiles, fewer carbapenemase genes (0.3% [five of 1858] vs. 4.1% [10 of 242]; P < 0.05) and a lower risk of being classified as multidrug-resistant than the imipenem-susceptible meropenem-resistant isolates (16.1% [299 of 1858] vs. 73.6% [178 of 242]; P < 0.05). Among all β-lactam combination agents, ceftazidime-avibactam and ceftolozane-tazobactam had higher susceptibility rates than meropenem-vaborbactam for meropenem-resistant P. aeruginosa (61.8% and 55.5% vs. 30.2%; P < 0.05).
    Conclusion: Discrepancy in the resistance of different P. aeruginosa isolates to various carbapenems suggests their different underlying resistance mechanisms. These findings can be useful for effective resistance trend monitoring and accurate antimicrobial treatment in the future.

    Abstract Objectives: Trends in the susceptibility to ceftazidime-avibactam (CZA) and tigecycline (TGC) among Enterobacter species from different geographic areas are unknown.This study aimed to analyse the trends in CZA and TGC susceptibility changes across different continents from 2014 to 2021 utilizing Antimicrobial Testing Leadership and Surveillance (ATLAS) data.
    Methods: A total of 23 669 isolates of Enterobacter species were collected over an 8-y period.
    Results: The overall non-susceptibility rate of Enterobacter isolates to both CZA and TGC was 3.2%. India (16.5%), Guatemala (15.4%), and the Philippines (13.1%) exhibited the highest resistance to CZA. The increase in CZA resistance rates was particularly evident in Asia, with an increase from 4.0% to 8.3%, and in Latin America, from 1.5% to 5%. The non-susceptibility rate for TGC mildly increased in Africa/Middle East but decreased in other continents during the study period. The overall rate of carbapenem resistance increased from 2.9% in 2014-2017 to 4.3% in 2018-2021. Among carbapenem-resistant Enterobacter isolates, the CZA resistance rate was highest in Asia (87.4%), followed by Europe (69.2%) and Africa/Middle East (60.8%). Among the 380 Enterobacter isolates resistant to CZA and carbapenem, the most common genotype of carbapenemase genes was bla
    Conclusions: The heterogeneous distribution of CZA resistance rates among different geographical regions highlights the divergent therapeutic options for drug-resistant Enterobacter species.

    Abstract Antimicrobial-resistant Escherichia coli in the aquatic environments is considered a strong indicator of sewage or animal waste contamination and antibiotic pollution. Sewer construction and wastewater treatment plant (WWTP) infrastructure may serve as concentrated point sources of contamination of antibiotic-resistant bacteria and antibiotic resistance genes. In this study, we focused on the distribution of antimicrobial-resistant E. coli in two rivers with large drainage areas and different urbanisation levels. E. coli from Kaoping River with drainage mainly from livestock farming had higher resistance to antibiotics (e.g. penicillins, tetracyclines, phenicols, aminoglycosides, and sulpha drugs) and presented more positive detection of antibiotic-resistance genes (e.g. ampC, bla

    Abstract Stenotrophomonas maltophilia is an emerging opportunistic pathogen for which there are limited therapeutic options because of intrinsic multidrug resistance. S. maltophilia isolates were collected as part of the Antimicrobial Testing Leadership and Surveillance (ATLAS) program and minimum inhibitory concentrations (MICs) were determined using broth microdilution methods. Susceptibility was interpreted according to Clinical and Laboratory Standards Institute (CLSI) breakpoints. Isolates with tigecycline MIC ≤2 mg/L were defined as susceptible, using the United States Food and Drug Administration criteria of Enterobacterales. A total of 2330 S. maltophilia isolates were collected from 47 countries worldwide in the ATLAS program from 2004 to 2020. Most patients were hospitalized (92.3%, 2151/2330) and respiratory tract infections (47.8%, 1114/2330) were the most common source of isolates. Minocycline had the highest susceptibility rate (98.8%), followed by levofloxacin (85.0%), trimethoprim-sulfamethoxazole (TMP-SMX) (84.4%), and ceftazidime (53.7%). A total of 98.3% (2290/2330) of S. maltophilia isolates had tigecycline MIC ≤2 mg/L. Among the S. maltophilia isolates exhibiting resistance to levofloxacin and ceftazidime, 89.3% (150/168) and 97.3% (692/711), respectively, were susceptible to tigecycline. Eight countries provided more than 30 isolates and were selected for comparison. Geographical difference in antimicrobial resistance was significant for levofloxacin, minocycline, and tigecycline (all P<0.05) but not for ceftazidime (P=0.467). These in vitro data demonstrated that minocycline had a higher susceptibility rate than levofloxacin and ceftazidime, and that tigecycline could be an alternative or salvage option for the treatment of S. maltophilia infections.

    Abstract Introduction: Bloodstream infections are associated with high mortality rates and contribute substantially to healthcare costs, but a consensus on the prognostic benefits of appropriate empirical antimicrobial therapy (EAT) for bacteraemia is lacking.
    Methods: We performed a systematic search of the PubMed, Cochrane Library, and Embase databases through July 2021. Studies comparing the mortality rates of patients receiving appropriate and inappropriate EAT were considered eligible. The quality of the included studies was assessed using Joanna Briggs Institute checklists.
    Results: We ultimately assessed 198 studies of 89,962 total patients. The pooled odds ratio (OR) for the prognostic impacts of inappropriate EAT was 2.06 (
    Conclusion: Although the current evidence is insufficient to demonstrate the benefits of prompt EAT in specific bacteraemic populations, we indicated that inappropriate EAT is associated with unfavorable mortality outcomes overall and in numerous subgroups. Prospective studies designed to test these specific populations are needed to ensure reliable conclusions.
