Sequence Type 48 Escherichia coli Carrying the blaCTX-M-1 IncI1/ST3 Plasmid in Drinking Water in France.

Drinking water has rarely been recognized as a source of antimicrobial resistance for humans, and only in low-income countries. Here, a sequence type 48 Escherichia coli isolate carrying the blaCTX-M-1 IncI1/ST3 plasmid was recovered from drinking water in France. This plasmid was similar to other blaCTX-M-1 IncI1/ST3 plasmids found previously in animals and humans.

High prevalence of international ESBL CTX-M-15-producing Enterobacter cloacae ST114 clone in animals.

Objectives: The objective of this study was to characterize ESBL-producing Enterobacter cloacae isolated from animals and to compare their clonal distribution with that of human-related isolates.

Methods: Among 635 clinical E. cloacae from horses, dogs and cats collected in France between 2010 and 2013, 36 were resistant to ceftiofur as determined by disc diffusion.

Population structure and antimicrobial susceptibility of Pseudomonas aeruginosa from animal infections in France.

Background: Pseudomonas aeruginosa is a major human pathogen, which also affects animals. It is thought that P. aeruginosa has a non-clonal epidemic population structure, with distinct isolates found in humans, animals or the environment.

Characterization of resistance genes in multidrug-resistant Salmonella enterica serotype Typhimurium isolated from diseased cattle in France (2002 to 2007).

We report here the results of the survey of antimicrobial resistance in 148 serotype Typhimurium strains isolated from cattle in France from 2002 to 2007 and displaying more than two antimicrobial resistances. Salmonella enterica serotype Typhimurium of definitive phage type 104 strains that are commonly resistant to ampicillin-amoxicillin, chloramphenicol-florfenicol, streptomycin-spectinomycin, sulfonamides, and tetracycline (ACSSuT phenotype) harbored resistance genes clustered on a complex class 1 integron In104 of the Salmonella genomic island 1 (SGI1). In our isolates, the most common antimicrobial resistance pattern was ACSSuT (77.
