Summary: This study characterized 376 extraintestinal pathogenic E. coli strains collected from hospitals in Catalonia, Spain, between 2016 and 2017. The strains showed high resistance to several antibiotics and varied biofilm formation ability. Various virulence and antimicrobial resistance genes were detected, including the colibactin-encoding genes associated with colorectal cancer. The study also investigated the relationship between colibactin and biofilm formation.

Summary: This study investigated the presence, pathogenic potential, and antimicrobial susceptibility profile of Escherichia coli in raw milk cheese in the Banat region, Romania. The findings revealed that these products may harbor virulent and multidrug-resistant E. coli strains, highlighting a potential public health risk.

Summary: Lower urinary tract, renal, and bloodstream infections caused by phylogroup B2 extraintestinal pathogenic Escherichia coli (ExPEC) are a leading cause of morbidity and mortality. ST1193 is a multidrug-resistant sequence type of B2 phylogroup E. coli that is associated with various human infections. This study analyzed the virulence plasmids carried by ST1193 and found that they are similar to pUTI89, a key F virulence plasmid found in dominant extraintestinal pathogenic E. coli lineages. The findings of this study have significant implications for the epidemiological source tracking of ExPEC.

Summary: The study determined the phylogenetic background and prevalence of diarrheagenic E. coli and antimicrobial resistance in healthy riding-horses in Iran. The most prevalent antimicrobial resistance phenotypes were against amoxicillin/clavulanic acid and ceftriaxone. The study also found that 26.15% of the E. coli isolates were multi-drug resistant (MDR).

Summary: This study investigated the effects of yeast and bacteria administered in drinking water on broiler chickens. The results showed that probiotics did not impact growth performance or microbial populations significantly. Additionally, there was no significant effect on antimicrobial resistance or virulence genes. Furthermore, the population of coliforms, Lactobacillus sp. and yeast decreased with age.

Summary: This study investigated E. coli strains isolated from raw milk of dairy cattle in Northern China, as well as their antibacterial susceptibility and essential virulence genes. The results showed that most E. coli strains were multidrug resistant and possessed multiple virulence genes, posing a potential hazard to public health, and antibiotic resistance was prevalent in dairy herds in Northern China.

Summary: This study investigated the antibiotic resistance and multilocus sequence typing (MLST) characteristics of Escherichia coli in neonatal intensive care units (NICUs) across China. The results showed that neonatal E. coli isolates had high levels of antibiotic resistance and different ST types were associated with different resistance patterns. ST410 had the highest resistance rate to cefotaxime and the most severe multidrug resistance.

Summary: High and often inappropriate antibiotic use in residential aged care facilities (RACFs) contributes to the development of antimicrobial resistance (AMR). However, limited surveillance of AMR prevalence and scope in RACFs has been conducted. In this study, wastewater-based epidemiology was used to analyze the prevalence of antimicrobial-resistant Escherichia coli in two RACFs and one retirement facility. The findings revealed a higher prevalence of AMR and multidrug-resistant E. coli in one RACF, including the presence of the high-risk E. coli clone ST131 carrying CTX-M-like extended-spectrum beta-lactamases. The resistome analysis also identified a higher prevalence of mobile resistance genes in this facility. The study highlights the need for measures to limit AMR development in RACFs, potentially through antimicrobial stewardship.

Summary: This study investigated the antimicrobial resistance and virulence genes of 181 Escherichia coli strains isolated from anal swab samples of pigs and chickens in Eastern China. The results revealed high levels of multidrug resistance and the presence of various virulence genes in these strains, emphasizing the need for routine surveillance of antimicrobial resistance using genomic approaches.

Summary: Pathogenic Escherichia coli causes disease in humans and food-producing animals. Its pathogenesis depends on virulence factors and antimicrobial resistance genes. Contaminated and undercooked food products are highly associated with food-borne outbreaks. It is important to identify the genetic factors that contribute to the virulence and antimicrobial resistance of E. coli.

Summary: The prevalence of ST131, especially among ciprofloxacin resistant isolates, increased from fecal to clinical samples in women, men, and children. ST131 isolates showed higher virulence potential compared to non-ST131 isolates, particularly in urinary samples. There was a strong association between ST131 prevalence and fluoroquinolone resistance, with FQ resistant ST131 isolates harboring more virulence genes.

Summary: This study isolated pathogenic E. coli from pigs with diarrhea in Korea post-antibiotic ban, revealing an overall increasing trend in antibiotic resistance among the bacteria. Most isolates exhibited multidrug resistance, highlighting the need for effective control measures in piggeries to address enteric colibacillosis.

Summary: Pathogenic E. coli in sheep from large-scale farms in China exhibit differences in antimicrobial resistance, virulence genes, and biofilm formation. Free-range sheep have fewer antibiotic-resistant strains but higher levels of virulence genes and biofilm formation compared to intensively farmed sheep.
