Detection of multiple extensively-drug resistant hypervirulent clones from patients with ventilator-associated pneumonia in Egypt.

Hypervirulent- (hvKP) is an evolving pathotype that is more virulent than the classical- (cKP) and causes serious fatal illnesses. Although there are few reports on hvKP isolated from Egyptian patients, the molecular characteristics and clonal relatedness of MDR-hvKP have not been adequately investigated. To investigate the microbiological and genetic characteristics as well as the epidemiology of hvKP induced ventilator-associated pneumonia (VAP).
