Dissemination and characterization of Escherichia coli resistant to extended-cephalosporins in feedlot lambs: A two-year two-population study.

Dissemination of antimicrobial resistance in food animals is a One Health concern, but sheep production has been overlooked. This study aimed to explore the dissemination of Escherichia coli resistant to extended-spectrum cephalosporins (ESC) in feedlot lambs. Two pens were sampled on two occasions, and carcasses and other mammals living around were also tested.

Prevalence of Antimicrobial Resistance and Clonal Relationship in ESBL/AmpC-Producing Isolated from Meat Products and Community-Acquired Urinary Tract Infection (UTI-CA) in Southern Brazil.

The present study aimed to evaluate the prevalence of antimicrobial resistance and clonal relationships in isolated from chicken meat, beef, pork, and community-acquired urinary tract infections (UTI-CA). Chicken meat isolates showed the highest multidrug resistance (MDR), followed by those from pork and UTI-CA, whereas beef had relatively few MDR strains. All sources had strains that carried , whereas and were only detected in chicken meat and UTI-CA isolates.

Genomic analysis of Escherichia coli circulating in the Brazilian poultry sector.

Escherichia coli are gut commensal bacteria and opportunistic pathogens, and the emergence of antimicrobial resistance threatens the safety of the food chain. To know the E. coli strains circulating in the Brazilian poultry sector is important since the country corresponds to a significant chicken meat production.

Proteus mirabilis from community-acquired urinary tract infections (UTI-CA) shares genetic similarity and virulence factors with isolates from chicken, beef and pork meat.

Proteus mirabilis is an opportunistic pathogen associated with a variety of infections in humans, especially those in the urinary tract. The isolation of this pathogen in foods of animal origin such as meat is poorly documented and should not be neglected, in view of the zoonotic risk that this can pose to human health. Thus, the objective of this study was to evaluate the prevalence, virulence profile, and similarity between P.

Potentially Pathogenic Multidrug-Resistant in Lamb Meat.

Extended-spectrum cephalosporin (ESC) resistance remains a threat since ESC are important antimicrobials used to treat infections in humans and animals. is an important source of ESC-resistance genes, such as those encoding extended-spectrum β-lactamases (ESBLs). is a common commensal of lambs.

Molecular and phenotypic characterization of diarrheagenic Escherichia coli isolated from groundwater in rural areas in southern Brazil.

Water-borne diseases like diarrheagenic Escherichia coli (DEC)-induced gastroenteritis are major public health problems in developing countries. In this study, the microbiological quality of water from mines and shallow wells was analyzed for human consumption. Genotypic and phenotypic characterization of DEC strains was performed.

Dissemination of Multidrug-Resistant Commensal in Feedlot Lambs in Southeastern Brazil.

Antimicrobial resistance (AR) is a public health issue since it limits the choices to treat infections by in humans and animals. In Brazil, the ovine meat market has grown in recent years, but studies about AR in sheep are still scarce. Thus, this study aims to investigate the presence of AR in isolated from lambs during feedlot.
