Methods Isolates from 17890 clinical specimens were identified by API20E. Antibiotic
susceptibility testing and MIC were done for MDR isolates. For investigating class 1 …

Background The aim of this study was to characterize class 1, 2 and 3 integrons in clinical
MDR Klebsiella pneumoniae isolates in Kashan, Iran. Methods One hundred-eighty one …

We investigated the prevalence of multidrug resistance, production of extended-spectrum b-
lactamases (ESBLs), and presence of class 1 and 2 integrons in 150 clinical isolates of …

Klebsiella pneumoniae is by far one of the most common Enterobacteriaceae associated
with hospital-acquired infections. The dissemination of multi drug resistant Klebsiella …

Objectives This study describes the distribution of integrons and phylogenetic groups among
clinical highly virulent serotype (HVS) Klebsiella pneumoniae isolates in a Chinese tertiary …

Background Klebsiella pneumoniae strains carrying class 1 integrons are becoming more
common worldwide, and their role in the dissemination of drug resistance is significant. The …

Background Integrons are mobile genetic elements that play an important role in the
distribution of antibiotic-resistance genes among bacteria. This study aimed to investigate …

To investigate molecular mechanism of multi-resistance of Klebsiella pneumoniae and its
spreading, 179 strains isolated from different clinical samples in the period of 2002-2007 …

Klebsiella is an opportunistic human pathogen and responsible for many of nosocomial
infections. Gram-negative bacteria can acquire antibiotic resistance genes through several …

Objective Klebsiella pneumoniae is one of most opportunistic pathogens that can be related
to nosocomial infections. Increased acquisitions of multidrug resistance in this bacterium as …
