Summary: This study investigated the phenotypic and genotypic characteristics of FQ-resistant E. coli isolates from broiler breeder farms in Korea, revealing that all isolates had mutations in quinolone resistance determining regions, with double mutations in gyrA being the predominant type. The presence of various plasmid-mediated quinolone resistance genes in PMQR-positive isolates was also identified. Monitoring and studies at the broiler breeder level are essential to prevent the pyramidal transmission of FQ-resistant E. coli.

Summary: Campylobacter jejuni and Salmonella typhimurium are leading causes of bacterial food contamination in chicken carcasses. This study isolated these bacteria from chicken carcass samples in Riyadh, Saudi Arabia, and identified them using phenotypic and genetic methods. The isolates showed multidrug resistance, and the identification was successful using specific molecular sizes and gene sequencing.

Summary: This study investigated antimicrobial resistance in turkeys in Canada and found a high prevalence of resistant Campylobacter isolates. Despite minimal use of tetracyclines and fluoroquinolones, a significant proportion of C. jejuni and C. coli isolates exhibited resistance to these drugs. Regional differences in resistance prevalence were observed, and certain antimicrobial classes may have contributed to the maintenance of resistance.

Summary: This study investigated the AMR patterns and tetracycline-resistant gene profiles of E. coli in broiler meat and livers from live bird markets and supermarkets in Chattogram, Bangladesh. The results showed high prevalence of resistance against multiple antibiotics and the presence of multi-drug resistant E. coli strains. It also revealed the widespread presence of tetracycline-resistant genes in E. coli isolates. This highlights the need for proper management of antimicrobial use in poultry farming and emphasizes the public health risks associated with AMR in broiler-associated pathogens.

Summary: The study conducted in poultry farms of coastal Southern Karnataka, India, found high levels of antibiotic resistance in Escherichia coli and Klebsiella pneumoniae isolates, with a focus on resistance to fluoroquinolones and tetracycline. The most common resistance genes detected were qnrB, qnrS, and qnrA, with most isolates showing high MAR indices reflecting widespread antibiotic use.

Summary: This study investigated the spread of ESBL-producing and fluoroquinolone-resistant avian pathogenic E. coli (APEC) in Kagoshima, Japan. The results showed the presence of various ESBL genes and fluoroquinolone-resistant strains. The study emphasizes the importance of prudent use of antimicrobials and careful monitoring of resistant strains in poultry farms and hatcheries.

Summary: In a four-year active surveillance study at four metropolitan hospitals in Michigan, an increasing trend in Campylobacter jejuni infections was observed. Analysis of 214 C. jejuni isolates revealed widespread antibiotic resistance, with differences in infection rates by hospital type and patient characteristics associated with disease severity.

Summary: Campylobacter, a Gram-negative bacteria, is the main cause of acute bacterial enteritis in humans, mainly transmitted through contaminated chicken meat. Prevention and reduction of Campylobacter colonization in poultry farms can help cut off infection transmission routes, leading to increased research in natural and safe alternatives in the future.

Summary: This study utilized data from the Canadian Integrated Program for Antimicrobial Resistance Surveillance to investigate factors associated with the isolation of FQr C. jejuni in broiler flocks. The findings suggest that bird type, use of virginiamycin, rodent control measures, flock size, and water line disinfection methods are key factors influencing the prevalence of FQr C. jejuni. Biosecurity and sanitation procedures play a significant role in the dissemination of FQr C. jejuni in broiler flocks.

Summary: The study analyzed the drug resistance prevalence and genetic characteristics of fecal E. coli isolated from healthy children at a kindergarten in Beijing, China. The results showed high resistance to multiple antibiotics and observed clonal spread of certain prevalent sequence types among the isolates. The findings highlight the seriousness of multidrug resistance and potential pathogenicity of E. coli in healthy children, emphasizing the need for increased surveillance and control measures.

Summary: This study aimed to determine the prevalence of three genes (htrA, htrB, and ppk1) related to environmental persistence in C. jejuni and C. coli isolates obtained from abattoir samples at different stages. The overall prevalence of these genes was 40.3%, 93.3%, and 68.9%, respectively. Significant differences were found between the prevalence in C. jejuni and C. coli, with higher prevalence of htrA and htrB in C. coli, and higher prevalence of ppk1 in C. jejuni. Furthermore, a significant increase in the frequency of htrA and htrB genes in the final meat products compared to initial broiler samples was observed in C. jejuni. These results suggest the involvement of htrA and htrB genes in the environmental persistence of Campylobacter jejuni.
