Multidrug-resistant organisms are increasing in frequency. These organisms are typically resistant to several different pharmacological classes of antibiotics through a wide variety of resistance mechanisms (not just through beta lactamase production). The organisms below were encountered at GVH, displaying resistance to multiple classes of antibiotics or unusual resistance characteristics.
- MRSA
- CRE: carbapenem-resistant Enterobacteriaceae
- VRE: Vancomycin-Resistant Enterococcus
- ESBL: Organism which produce extended-spectrum beta lactamases, which confer resistance to ALL beta lactams except carbapenems; most ESBL+ organisms belong to the Enterobacteriaceae group
- VRSA: Vancomycin-Resistant Staph Aureus
