Functional characterization of Tn4401, a Tn3-based transposon involved in blaKPC gene mobilization.

چکیده
The carbapenemase gene bla(KPC), which is rapidly spreading worldwide, is located on a Tn3-based transposon, Tn4401. In a transposition-conjugation assay, Tn4401 was able to mobilize bla(KPC-2) gene at a frequency of 4.4 × 10(-6)/recipient cell. A 5-bp target site duplication was evidenced upon each insertion without target site specificity. This study demonstrated that Tn4401 is an active transposon capable of mobilizing bla(KPC) genes at high frequency.

Molecular characterization of newly emerged blaKPC-2-producing Klebsiella pneumoniae in Singapore.
In Asia, bla(KPC) detection has been limited to East Asia and not yet seen in Southeast Asia. We report four bla(KPC-2)-containing Klebsiella pneumoniae isolates from two different hospitals in Singapore. All isolates belonged to strain type 11 (ST11) and were indistinguishable by pulsed-field gel electrophoresis (PFGE). bla(KPC-2) was located on nonconjugative plasmids and flanked by mobile ge...
متن کاملNested Russian Doll-Like Genetic Mobility Drives Rapid Dissemination of the Carbapenem Resistance Gene blaKPC
The recent widespread emergence of carbapenem resistance in Enterobacteriaceae is a major public health concern, as carbapenems are a therapy of last resort against this family of common bacterial pathogens. Resistance genes can mobilize via various mechanisms, including conjugation and transposition; however, the importance of this mobility in short-term evolution, such as within nosocomial ou...
متن کاملWorldwide Diversity of Klebsiella pneumoniae That Produce β-Lactamase blaKPC-2 Gene1
Klebsiella pneumoniaeisolates that produce carbapenemases (KPCs) are rapidly disseminating worldwide. To determine their genetic background, we investigated 16 blaKPC-2-harboring K. pneumoniae isolates from 5 countries. The isolates were multidrug resistant, possessed the blaKPC-2 gene, and differed by additional Beta-lactamase content. They harbored a naturally chromosome-encoded bla gene (bla...
متن کاملCharacterization of Metagenomes in Urban Aquatic Compartments Reveals High Prevalence of Clinically Relevant Antibiotic Resistance Genes in Wastewaters
The dissemination of antimicrobial resistance (AMR) is an escalating problem and a threat to public health. Comparative metagenomics was used to investigate the occurrence of antibiotic resistant genes (ARGs) in wastewater and urban surface water environments in Singapore. Hospital and municipal wastewater (n = 6) were found to have higher diversity and average abundance of ARGs (303 ARG subtyp...
متن کاملChromosomal Integration of the Klebsiella pneumoniae Carbapenemase Gene, blaKPC, in Klebsiella Species Is Elusive but Not Rare
Carbapenemase genes in Enterobacteriaceae are mostly described as being plasmid associated. However, the genetic context of carbapenemase genes is not always confirmed in epidemiological surveys, and the frequency of their chromosomal integration therefore is unknown. A previously sequenced collection of blaKPC-positive Enterobacteriaceae from a single U.S. institution (2007 to 2012; n = 281 is...
