Gram negative rod, of the Enterobacteriaceae family.
Nosocomial infections:
May require contact precautions if highly resistant.
Resistance may develop during therapy if treated with cephalosporins or beta-lactam/beta-lactamase inhibitors, even if susceptible in vitro. Piperacillin-tazobactam should only be considered for these pathogens in limited clinical scenarios if susceptibility confirmed; contact a medical-microbiologist for more information
