A new method is described which makes it possible to treat metal materials with microwaves. In consequence scalpel blades as well as cover glasses contaminated with four species of bacteria (Salmonella typhi, Proteus mirabilis, Escherichia coli and Pseudomonas aeruginosa) were sterilized. With this method sterilization can be achieved quite rapidly (1.5-2 min). Scanning electron microscopy revealed a progressive alteration in the morphology of micro-organisms and this proved proportional to the microwave exposure time. Only in Proteus mirabilis were no modifications found, even after long periods of microwave exposure.

Introduction: The exact triggers of gallstone formation remain incompletely understood, but research indicates that microbial infection is a significant factor and can interfere with treatment. There is no consensus on the bile microbial culture profiles in previous studies, and determining the microbial profile could aid in targeted prevention and treatment. The primary aim of this study is to investigate the differences in microbial communities cultured from bile specimens of patients with gallstones.

The reliability of ceftriaxone for inferring susceptibility to higher-generation oral cephalosporins is unknown. Overall, ceftriaxone susceptibility predicted susceptibility to cefuroxime (89%), cefdinir (86%), cefpodoxime (90%), and cefixime (94%) based on disk diffusion results for 409 consecutive Enterobacterales bloodstream isolates from unique patients. Susceptibility percentages to the four oral cephalosporins ranged from 92% to 99% when limited to , isolates susceptible to ceftriaxone.

Introduction: Urinary tract infections (UTIs) are one of the most prevalent infections in North America and are caused by a diverse range of bacterial species. Although uropathogenesis has been studied extensively in the context of macromolecular interactions, the degree to which metabolism may contribute to infection is unclear. Currently, most of what is known about the metabolic capacity of uropathogens has been derived from genomics, genetic knockout studies or transcriptomic analyses.

Antimicrobial resistance (AMR) poses a significant global threat to public health systems, rendering antibiotics ineffective in treating infectious diseases. Combined use of bio compounds, including bacteriophages and plant extracts, is an attractive approach to controlling antibiotic resistance. In this study, the combination of phage cocktail (Isf-Pm1 and Isf-Pm2) and crude extract (AME) was investigated in controlling biofilm-forming multi-drug resistant isolates, and a phantom bladder model.

The prevalence of foodborne diseases has raised concerns due to the potential transmission of zoonotic bacterial pathogens through meat products. The objective of this study was to determine the occurrence and antimicrobial resistance (AMR) profiles of pathogenic bacteria in cooked donkey meat products from Beijing. Twenty-one cooked donkey meat samples were collected from different delis, subjected to homogenization, and analyzed for bacterial contamination.
