Antibiotic resistant Escherichia coli strains in healthy pets from Tamaulipas, Mexico.

Antibiotic resistance constitutes a significant public health challenge, with diverse reservoirs of resistant bacteria playing pivotal roles in their dissemination. Among these reservoirs, pets are carrying antibiotic-resistant strains. The objective of this study was to assess the resistance profiles of Escherichia coli, and the prevalence of extended-spectrum β-lactamase (ESBL) producing E.

Molecular and Antimicrobial Susceptibility Characterization of Isolates from Bovine Slaughterhouse Process.

Antimicrobials are routinely used in human and veterinary medicine. With repeated exposure, antimicrobials promote antibiotic resistance, which poses a threat to public health. In this study, we aimed to determine the susceptibility patterns, virulence factors, and phylogroups of isolates during the killing process in a bovine slaughterhouse.

Multidrug Resistance of Strains Isolated From Bovine Feces and Carcasses in Northeast Mexico.

In this work, the antimicrobial resistance profile of strains ( = 248) isolated from bovine feces and carcass samples from Tamaulipas, Mexico, was evaluated. Susceptibility to 12 antibiotics conventionally used in human and veterinary treatments was determined according to Clinical and Laboratory Standards Institute guidelines. Genes encoding resistance to tetracycline ( and ), streptomycin (A), aminoglycoside (A), and β-lactamase ( and ) were investigated by PCR.
