Emergence of OXA-48 carbapenemase-producing Enterobacter cloacae ST89 infection in Poland

Abstract

We report a case of infection caused by a unique carbapenem-resistant E. cloacae ST89 producing OXA-48 carbapenemase. Interestingly, these pathogens developed resistance to other 'last-resort' agents, namely colistin and tigecycline. There is a crucial need for surveillance programs aimed at screening for carbapenemase-producing Gram-negative bacteria, especially in patients transferred from high-incidence areas.
