Summary: The study aimed to determine the suitability of FAA as a medium for disk diffusion for rapidly growing anaerobic bacteria, and results showed that FAA is suitable. Factors such as incubation temperature and manufacturer had an impact on zone diameters and quality of growth, with incubation at 35 degrees Celsius resulting in slightly larger zones and good agreement among manufacturers for FAA performance.

Summary: Anaerobes play a crucial role in clinically relevant infections and their resistance is becoming more widespread. In this study, 120 rare anaerobic isolates from 16 genera were tested for antimicrobial resistance using two different methods. Results showed low resistance to certain antibiotics, while moderate to high rates of resistance were observed for others, depending on the testing methodology. The findings highlight the importance of routine susceptibility testing and further investigations are needed to improve testing for fastidious anaerobes.

Summary: The application of droplet-based methods in antimicrobial resistance research allows for faster detection, increased sensitivity, characterization of heterogeneity in bacterial populations' response to antibiotics, and expanded screening of antibiotic combinations. This article discusses the key steps and parameters of droplet-based experiments, reviews recent findings achieved with these methods, and highlights their advantages and capacity to provide new insights into the problem of antimicrobial resistance.

Summary: Gram-negative bacteria producing carbapenemases are resistant to beta-lactam antibiotics, posing a significant health risk. Taniborbactam is an investigational broad-spectrum beta-lactamase inhibitor effective against serine- and metallo-beta-lactamases, including KPC. This study demonstrated the effectiveness of taniborbactam in restoring the antibacterial activity of cefepime against KPC-3-producing Escherichia coli, highlighting its potential in combating beta-lactamase-mediated antibiotic resistance.

Summary: This study aimed to determine the prevalence and antimicrobial susceptibility profile of diarrhea-causing bacteria in Ghana. The study found that Escherichia coli, Salmonella, Vibrio, and Shigella were common bacteria implicated in diarrhea cases in Ghana, with Escherichia coli and Salmonella being the most prevalent. These isolates showed resistance to commonly used drugs, which may render treatment nearly impossible in the future. Routine antimicrobial susceptibility testing and nationwide surveillance of antimicrobial resistance pathogens should be implemented.

Summary: The study reviewed whether mutations and reduced susceptibility to disinfectants occur in bacteria during disinfectant exposure. It found significant deviations in the minimum inhibitory concentration for disinfectants based on triclosan and chlorhexidine, indicating a potential increase in disinfectant resistance and related issues with antibiotic resistance in clinically important bacterial strains.

Summary: This study analyzed the susceptibility of anaerobic strains to moxifloxacin from a multicenter research in Italy. The results showed that the resistance rates of Bacteroides spp. and other non-Bacteroides anaerobes to moxifloxacin varied when using different criteria. However, overall, an alarming increase in moxifloxacin resistance among anaerobes in Italy was observed.

Summary: The article discusses the use of antibiotics against anaerobic bacteria and reevaluates the concept of anti-anaerobic spectrum in light of developments in the microbiota field. By highlighting the diversity of anaerobic bacteria species and the lack of antibiotic susceptibility profiles for many anaerobic bacteria, the relevance of the anti-anaerobic spectrum is challenged from clinical and ecological perspectives.

Summary: This study compared the flow cytometry method with current standardized methods for determining the antibiotic susceptibility of bacterial strains. The results showed a high level of correlation between the two methods. Flow cytometry provided faster results within the same day and shortened the duration of the antibiotic susceptibility tests.

Summary: The study shows that the residues of rice parboiling industries in Brazil can be used to produce biogas, increasing the sector's self-sufficiency in energy. Adding 1% glycerol in anaerobic digestion significantly boosts methane production. However, higher doses of glycerol may lead to the interruption of methanogenic activity.

Summary: This study aimed to identify anaerobic bacteria isolated from clinical specimens and determine their antibiotic susceptibility. The most commonly isolated anaerobic bacteria were Clostridium spp. and Peptostreptococcus spp. The highest resistance was found against penicillin G, while the sensitivity to ceftolozane/tazobactam varied widely among different bacterial species.

Summary: The purpose of this study is to establish a method for evaluating the anaerobic environment for the EUCAST disk diffusion antimicrobial susceptibility testing (AST) of anaerobic bacteria. The method is based on the association between a decrease in the metronidazole disk zone diameter and increasing oxygen levels. The results indicate that a zone diameter of >= 25 mm using a metronidazole 5 μg disk and the C. perfringens strain, tested with EUCAST recommendations, can be used to indicate that the anaerobic environment is of sufficient quality for culture and disk diffusion AST.

Summary: Investigations on different ventilation strategies for concentrated landfill leachate and food waste co-bioevaporation revealed that intermittent ventilation with 10 min on and 20 min off (IV1) was the most effective strategy. This strategy resulted in higher removal efficiency of water and organics compared to continuous ventilation (CV) while consuming less energy. The diversity of bacteria and archaea were distinct between IV1 and CV, with IV1 showing higher diversity but lower richness. Anaerobic methanogens were significantly more abundant in IV1 than in CV, indicating a significant impact of ventilation strategy on microorganism colonization in co-bioevaporation piles.
