Abstract

Febrile neutropenic patients are at a high risk of life-threatening bacterial infections. Tigecycline was developed to treat multidrug-resistant isolates, however resistance to tigecycline in has been reported. Here, we investigated tigecycline resistance among isolated from febrile neutropenic patients admitted to Hematology ICU, Egypt. Out of 75 enrolled febrile neutropenic patients, 48 cases showed bacteriologically confirmed infection. The majority of cases were infected with , of which nine were tigecycline non-susceptible. Expression levels of the efflux pump genes and and their regulatory genes and were analysed. Six isolates had overexpression of the four efflux-related genes while one showed baseline expression. This study emphasizes the importance of growing tigecycline resistance in infecting febrile neutropenic patients. Concerning the mechanism of resistance, it was clear that the gene plays the major role, although alternative resistance mechanisms may also exist.
