Carbapenem-resistant Klebsiella pneumoniae (CRKP) has emerged as a formidable health challenge in recent years owing to the shortage of effective antibiotics. Colistin is the last and sometimes the only therapeutic option for CRKP infections. Unfortunately, resistance to colistin monotherapy is likely to develop. CRKP in China reportedly exhibit low rates of resistance to trimethoprim-sulfamethoxazole. The aim of this study was to evaluate the in vitro efficacy of trimethoprim-sulfamethoxazole in combination with colistin against four CRKP clinical isolates...
