Introduction: The ability of Spanish microbiology laboratories to (a) determine antimicrobial susceptibility (AS), and (b) correctly detect the vancomycin resistance (VR) phenotype in vancomycin-resistant Enterococcus spp. (VRE) was evaluated.
Methods: Three VRE isolates representing the VanA (E.

Inhibitor-resistant TEM- and OXA-1-producing Escherichia coli isolates resistant to amoxicillin-clavulanate are more clonal and possess lower virulence gene content than susceptible clinical isolates.

Article Synopsis
- A previous study identified OXA-1 and inhibitor-resistant TEM β-lactamases as major mechanisms of amoxicillin-clavulanate resistance in E. coli in Spain.
- The current research analyzed the genetic and virulence characteristics of clinical AMC-resistant E. coli strains compared to AMC-susceptible strains, revealing different prevalent clones for each resistance group.
- Results indicated that AMC-susceptible E. coli had a more diverse population structure and higher virulence factor presence compared to OXA-1 and IRT producers.
Twenty blood isolates of Acinetobacter baumannii were studied, representing eight pulsed-field gel electrophoresis patterns and all different antimicrobial susceptibility patterns observed during 1995-97 at the University Hospital Virgen Macarena, Seville, Spain. The MIC(90)s (mg/L) of imipenem and meropenem decreased from 16 to 0.5 and from 8 to 4, respectively, in the presence of BRL 42715 (BRL) but not clavulanic acid.
