Characterisation of the first CTX-M-10-producing isolate of Salmonella enterica serotype Virchow

Microbiological analysis of a urine sample from an outpatient with symptoms of urinary infection detected >105 CFU/mL urine of Salmonella enterica serotype Virchow with resistance to cefotaxime. Molecular analysis demonstrated the presence of the gene encoding CTX-M-10 β-lactamase in this clinical isolate. This is the first report of this enzyme in Salmonella spp.
