MBLs, Rather Than Efflux Pumps, Led to Carbapenem Resistance in Fosfomycin and Aztreonam/Avibactam Resistant Elizabethkingia anophelis.

Our findings will help clinicians to identify high-risk patients and suggests that minocycline should be considered as a therapeutic option for E. anophelis infections. Additionally, carbapenem resistance in E. anophelis is mainly associated with the MBLs, BlaB and GOB, rather than various putative efflux pumps.
