Popis výsledku v původním jazyce

Background: VIM metallo-β-lactamases are enzymes characterized by the ability to hydrolyze all β-lactams. Usually, blaVIM-like genes are carried by class 1 integrons. In the Czech Republic, only sporadic cases of VIM-producing Enterobacterales have been reported in which those isolates carried the VIM-1 carbapenemase-encoding integron In110. However, during 2019-2020, an increased number was reported. Therefore, the aim of the current study was to characterize the genetic elements involved in the increased spread of blaVIM genes.Materials and methods: 32 VIM-producing Enterobacterales collected between 2019 and 2020 were subjected to: antimicrobial susceptibility testing, integron analysis, and short reads sequencing. Based on the results, 19 isolates were selected as representative and sequenced using Sequel I platform.Results: The 32 VIM-producing isolates exhibited variations in the MICs of carbapenems. Based on short-read data, 26 of the 32 sequenced isolates harbored the blaVIM-1 allele while six isolates carried the blaVIM-4 gene. The most prevalent was the In110 integron (n = 24) and two isolates carried the In4873 class 1 integron. The blaVIM-4 allele was identified in class 1 integrons In1174 (n = 3), In416 (n = 1), In2143 (n = 1) and In2150. Long reads sequencing revealed that the blaVIM was carried by: pKPC-CAV1193-like (n = 6), HI1 (pNDM-CIT; n = 4), HI2 (n = 3), FIB (pECLA; n = 2) and N (n = 1) incompatibility groups. Two blaVIM-carrying plasmids could not be typed by the database, while another one was integrated into the chromosome.Conclusion: We observed the spread of VIM-encoding integrons, mainly of In110, among Enterobacterales isolated from Czech hospitals, but also an increased number of novel elements underlining the ongoing evolution.
