An Outbreak of (X6)-Carrying Tigecycline-Resistant Isolates with a New Capsular Type at a Hospital in Taiwan.

Dissemination of multidrug-resistant, particularly tigecycline-resistant, is of critical importance, as tigecycline is considered a last-line antibiotic. Acquisition of (X), a tigecycline-inactivating enzyme mostly found in strains of animal origin, imparts tigecycline resistance to . Herein, we investigated the presence of (X) variants among 228 tigecycline-non-susceptible isolates from patients at a Taiwanese hospital via polymerase chain reaction using a newly designed universal primer pair.
