Leminorella spp
Gram Stain- Gram negative bacilli - fermenter
These organisms have been associated with nosocomial infections including urinary tract, respiratory tract, surgical site, skin and soft tissue infections, bacteremia, and peritonitis.
Usual Susceptibility Pattern
These organisms produce a chromosomal extended spectrum beta-lactamase (CTX-M ESBL) and should be considered resistant to all penicillins and 1st/2nd generation cephalosporins.
Third generation cephalosporins may have diminished activity.
Carbapenems retain activity.
They are typically susceptible to TMP/SMX, quinolones, and aminoglycosides.
