Our research showed that even single-day dose use of carbapenems caused CRKP colonization and continuous bacterial shedding, which reminds clinical doctors to prescribe carbapenems cautiously. Whenever possible, ertapenem should be the preferred choice over other carbapenems especially when the identified or highly suspected pathogens can be effectively targeted by ertapenem.
