Summary: Escherichia coli is a commensal of the human and animal intestinal tract, but certain pathogenic strains can cause severe infections. Wildlife may carry and transmit these pathogenic strains, posing a potential source of infection for humans and domestic animals. Red foxes, in particular, seem to play a role in the epidemiology of these infections, especially when they invade human settlements in rural and urban areas.

Summary: Escherichia coli are versatile microorganisms found in the normal intestinal microbiota of humans and animals. They can become emerging human pathogens by acquiring genes encoding virulence factors. Nine enteric E. coli pathotypes have been characterized, utilizing various virulence factors to cause intestinal and extraintestinal diseases.

Summary: Recent foodborne illness outbreaks have increased pressure on farmers to keep wildlife out of farms, but it is still unclear which species pose the greatest risk to food safety. Through testing and surveys of wild birds in the western United States, it was found that traits associated with pathogen exposure predicted pathogen prevalence, and species associated with feedlots were more likely to enter fields and defecate on crops.

Summary: Some bacterial resistance mechanisms can degrade antibiotics, potentially protecting neighboring susceptible cells. However, the effects of such mechanisms on bacterial communities of more than two species are not well understood. By conducting experiments on multispecies communities, we found that resistance in one species reduced antibiotic inhibition of other species, but the extent of benefit varied among species.

Summary: Transfer of wild mouse gut microbiota to laboratory mice enhances immune status and resistance to diseases, with Helicobacter spp. being enriched in wild mice. Experiments with non-SPF Helicobacter spp. in mice show interference with Citrobacter rodentium colonization and gut inflammation, suggesting a protective function against intestinal infection. Results indicate that Helicobacter spp. interfere with C. rodentium tissue attachment, potentially by reducing mucus-derived sugars.

Summary: Enterotoxigenic Escherichia coli (ETEC), a diarrheal pathogen, can utilize ethanolamine (EA) as a nitrogen source, which enhances its virulence phenotype and causes damage to host intestinal cells. The concentration of EA in the intestine also impacts the metabolic profile and pathogenicity of ETEC.

Summary: This study investigates the relationship between flagella expression and the type III secretion system (T3SS) in enteropathogenic Escherichia coli (EPEC). The results suggest that the assembly of an intact T3SS is required for flagella production, and certain regulator genes play a role in activating or inhibiting flagella expression.

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 investigates the antimicrobial resistance and virulence threats of Escherichia coli isolates recovered from intestinal and fecal samples of chickens, turkeys, and sparrows. The study finds that sparrows could be a vector in the dissemination of ESBL-producing E. coli isolates to other environments. Additionally, this study reports the first detection of the bla(CTX-M-14) gene from sparrows at a global level and in turkeys in Algeria.

Summary: In this study, it was found that Probiotic Escherichia coli Nissle 1917 (EcN) inhibits the growth of Salmonella by producing the antimicrobial substance MccM. EcN::mcmA strain also reduced the adhesion and invasion ability of Salmonella to intestinal epithelial cells and decreased the secretion of inflammatory factors. These findings suggest that EcN::mcmA can be developed as engineered probiotics to combat pathogenic enterobacteria colonization in the gut.

Summary: Extraintestinal pathogenic Escherichia coli (ExPEC) is a globally distributed pathogen associated with human and companion animal diseases, while avian pathogenic pathotype (APEC) severely impacts poultry health and production. The similarities between APEC and human ExPEC suggest a potential for zoonotic transmission.

Summary: Salmonella serovars Heidelberg and Minnesota with resistance to third-generation cephalosporins and fluoroquinolones are frequently found in Brazilian poultry. Genomic analysis revealed the presence of virulent and multidrug-resistant characteristics in these isolates, with AmpC beta-lactamase (bla(CMY-2)) predominance in Salmonella Minnesota (SM) and some Salmonella Heidelberg (SH) on IncC plasmid replicons. The study also identified close genetic similarity between the Brazilian isolates and poultry/food isolates from Europe, as well as human isolates from European countries importing Brazilian poultry meat. Overall, this research highlights the ongoing acquisition and dissemination of antimicrobial resistance in SH and Minnesota, raising concerns for importing countries and emphasizing the need to control AMR in major poultry-exporting countries like Brazil.

Summary: This study determined the nasal carriage rate of coagulase-positive staphylococci (CoPS) in healthy dogs and in-contact people and investigated their genotypic characteristics and phylogenetic relatedness. The results showed clonally related CoPS in humans and dogs within some households, highlighting the importance of continuous surveillance from a One Health perspective.

Summary: The study investigated whether apparently healthy birds in protected areas in northeastern Brazil were shedding bacterial pathogens to the environment and found that different protected areas did not show a significant relationship in bacteria distribution. The birds in the sampled protected areas may host a variety of potentially pathogenic microorganisms, with antibiotic-resistant Enterobacterales posing a potential impact on bird populations and environmental conservation.
