Summary: Retail meat products are potential reservoirs and conduits for antimicrobial resistance, with the prevalence of Escherichia coli contamination varying significantly based on meat type and sampling season. Antimicrobial susceptibility testing revealed a high percentage of E. coli isolates resistant to multiple drugs, particularly in poultry counterparts. Whole-genome sequencing identified numerous antimicrobial resistance genes, indicating the heterogeneous nature of genomic AMR determinants in retail meat.

Summary: This study found 49 strains of Shiga toxin-producing Escherichia coli (STEC) in retail raw meats in Southeast China, belonging to 33 divergent O:H serotypes. These STEC strains carried multiple virulence factors, showed resistance to various antibiotics, and had the ability to form biofilms, posing potential health risks to consumers.

Summary: Analysis of food samples collected at retail stores in Beijing, China, showed high contamination levels of E. coli and enterococci in food-animal products, vegetables, aquatic products, and fruits, with significant multidrug resistance. Food-animal products were identified as the primary reservoir of antimicrobial resistance, while the role of vegetables, fruits, and aquatic products in spreading AMR should not be underestimated. Food-borne isolates displayed high resistance to antibiotics commonly used in agriculture, as well as those rarely used in agriculture/aquaculture, highlighting the potential for animal-to-human transmission of antibiotic resistance genes.

Summary: Campylobacter jejuni and C. coli are major causes of gastrointestinal illnesses transmitted to humans mainly through chicken meats. This study examined the levels of bacterial contamination in retail chicken meats in Japan and found that 45.7% of the samples were positive, with 8.4% exceeding the safe limit. Bacterial counts were higher in fall compared to spring and summer, and younger slaughtered chickens were more contaminated. The study also identified antimicrobial resistance genes and clonal complexes of C. jejuni isolates.

Summary: This study investigated the prevalence and risk factors for multidrug-resistant Klebsiella pneumoniae infection among hospitalized patients in southern Saudi Arabia. The study found that 66.8% of patients were infected with multidrug-resistant K. pneumoniae strains. Factors such as gender, age, intensive care unit admission, invasive medical devices, and chronic illness were significantly associated with the infection.

Summary: This study estimated the prevalence and antimicrobial resistance of Escherichia coli O157:H7 in raw beef sold in butcher shops in Addis Ababa, Ethiopia. Out of the 384 samples examined, 3.64% carried E. coli O157:H7, with 57.14% of the isolates showing resistance to three or more antimicrobial agents. Thus, stricter monitoring of antimicrobial use and further studies on contamination sources and risk mitigation strategies are needed.

Summary: This study investigated the prevalence, antimicrobial resistance, and virulence characteristics of Enterococcus faecalis and Enterococcus faecium in food animals and meats in Bangladesh. The findings suggest a high prevalence of multidrug-resistant enterococci in food animals and retail meats, posing a risk to consumers and limiting therapeutic options.

Summary: This study found that the presence of Staphylococcus aureus can enhance the survival of Campylobacter in adverse conditions such as low temperature and aerobic conditions, especially during biofilm formation. However, the results were inconclusive when extracts from cell-free media of S. aureus were used.

Summary: Natural ecosystems can serve as reservoirs and pathways for antimicrobial resistance dissemination, potentially affecting nearby communities. This study investigated the presence of antimicrobial resistance and co-selective stressors in rural groundwater supplies. The results suggest that antimicrobial resistance may originate from agricultural practices and occur prior to groundwater ingress.

Summary: This study investigated the prevalence of fluoroquinolone resistance in E. coli and Klebsiella spp isolated from children discharged from two hospitals in Kenya. The findings showed a high proportion of isolates that were non-susceptible to ciprofloxacin and carried multiple resistance genes. This suggests that discharged children may play a significant role in the transmission of antimicrobial-resistant bacteria to the community, highlighting the need for enhanced surveillance and interventions to control the spread of resistant bacteria.

Summary: This study analyzed the prevalence and genetic characteristics of Stx2e-STEC strains from humans, animals, and meats in China, finding a high proportion of Stx2e-STEC among human STEC strains; animal and meat-derived Stx2e-STEC strains showed multidrug resistance, while human strains were only resistant to azithromycin and tetracycline; the study suggests that animal and food-derived Stx2e-STEC strains may pose a risk of causing human disease.
