  • We have found that E. innesii carries a gene that makes the bacterium resistant to the antibiotic vancomycin. (jic.ac.uk)
  • For instance, two inpatient samples, or 24 percent, had the vancomycin regulatory resistance gene, while none had that gene in the outpatient group. (genomeweb.com)
  • Meanwhile, more than half of the outpatient cohort had an AmpC resistance gene, while 24 percent of inpatient samples had that gene. (genomeweb.com)
