- Abstract
A study published in the Journal of Antimicrobial Chemotherapy examined the development of resistance to ertapenem and meropenem among a type of bacteria called Enterobacterales. The researchers found that resistance to ertapenem occurred more easily than resistance to meropenem. They also observed that using ertapenem could potentially lead to resistance to meropenem. These findings emphasize the need to monitor and manage the use of carbapenem antibiotics to prevent resistance. Another study compared the effects of ertapenem and meropenem on carbapenem-resistant Enterobacteriaceae isolates. The study found that ertapenem isolates showed greater reductions in susceptibility compared to meropenem isolates. The authors suggest that this may support the use of meropenem over ertapenem in hospitals for treating these infections, but more research is needed. The study was funded internally and the authors have no conflicts of interest.
