Inoculum Effect Impacts CZA-Colistin Efficacy in K. pneumoniae

The in vitro study showed that increasing inoculum of KPC-3 K. pneumoniae reduced the activity of ceftazidime/avibactam (CZA) and colistin (CST), with the combination preventing resistance at moderate inocula. However, eradication failed at the highest inoculum. CZA and CST showed separate inoculum effects without interaction, suggesting IE should be considered in combination therapy strategies.
