Pleiotropic cellular responses underlying antibiotic tolerance in .

Antibiotic tolerance enables antibiotic-susceptible bacteria to withstand prolonged exposure to high concentrations of antibiotics. Although antibiotic tolerance presents a major challenge for public health, its underlying molecular mechanisms remain unclear. Previously, we have demonstrated that develops tolerance to clinically important antibiotics, including ciprofloxacin and tetracycline.

Prevalence of CTX-M types among ESBL-producing pathogenic isolates from foodborne diarrheal patients in Gyeonggi-do, South Korea.

Unlabelled: Prevalence and characteristics of extended-spectrum β-lactamase (ESBL)-producing pathogenic from foodborne diarrheal patients were studied. Analysis of 495 isolates revealed that 80 isolates were ESBL-producing pathogenic , and enteroaggregative and enterotoxigenic were two of the most prevalent pathotypes. In silico Clermont phylo-typing of the 80 ESBL-producing showed that phylogroup A (49/80) and D (22/80) were the predominant phylogroups.

Cold tolerance in Campylobacter jejuni and its impact on food safety.

Campylobacter jejuni is a major cause of foodborne illnesses worldwide and is primarily transmitted to humans through contaminated poultry meat. To control this pathogen, it is critical to understand its cold tolerance because poultry products are usually distributed in the cold chain. However, there is limited information regarding how this thermotolerant, microaerophilic pathogen can survive in cold and aerobic environments in the poultry cold chain.

Phylogenetic Association and Genetic Factors in Cold Stress Tolerance in Campylobacter jejuni.

Campylobacter jejuni is a major foodborne pathogen transmitted to humans primarily via contaminated poultry meat. Since poultry meat is generally processed, distributed, and stored in the cold chain, the survival of C. jejuni at refrigeration temperatures crucially affects human exposure to C.

Bacteriophage-Mediated Modulation of Bacterial Competition during Selective Enrichment of Campylobacter.

Selective media using antimicrobial supplements generate unique microbial ecology to facilitate bacterial isolation. However, antibiotic-resistant bacteria indigenous to samples can interfere with the isolation process using selective media. Recent studies showed that extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli is highly prevalent on retail raw chicken and compromises the efficacy of Campylobacter isolation because ESBL-producing E.
