Abstract excerpt
OBJECTIVES: To study at the molecular level the heterogeneity of expression of the two chromosomal beta-lactamases, BlaA and BlaB, in Yersinia enterocolitica strains isolated from clinical samples. METHODS: MIC determination by the agar dilution method and beta-lactamase assays was performed to determine the resistance level conferred by these enzymes. DNA cloning, PCR and direct sequencing were used to detect...
