Status of Antibiotic Susceptibility of Polymyxin B And Colistin in the Treatment of Carbapenem Resistant Gram Negative Bacterial Infections: An Observational Study

Polymyxin B and Colistin continue to be vital last-line treatments for carbapenem-resistant gram-negative bacteria. This study found a susceptibility rate of 100% to colistin and polymyxin B among carbapenem-resistant gramnegative bacteria. To maintain the efficacy and reliability of these antibiotics, it is essential to use them judiciously, conduct routine susceptibility testing, and implement ongoing surveillance.
