WebBackground: A rare member of metallo-β-lactamases genes, bla SIM-1, carried by a 316-kb plasmid designated pSIM-1-BJ01 was isolated from a clinical cephalosporins- and carbapenem-resistant Klebsiella pneumoniae 13624. This is the first sequence report of a transferable bla SIM-1-carrying conjugative plasmid isolated from K. pneumoniae. WebIncHI plasmid conjugation is thermodependent and all transfer‐related genes are encoded in six operons (tra operons). Using R27, the prototype of IncHI1 plasmids, we reported that the plasmid‐encoded factor HtdA represses four of the six tra operons.
WebSep 17, 2024 · IncHI plasmids represent 20% of all plasmids transmitting colistin resistance worldwide and 40% in Europe. When analyzing the interactions of the IncHI1 plasmid R27 with Salmonella, we identified a large-molecular-mass protein that is encoded by this plasmid and is exported to the external medium. WebThe common regions of the IncHI plasmids contain genes that are essential for plasmid replication, maintenance, and transmission (which might define the general backbone for the group), as well as an extensive series of homologous core genes. Acquired DNA, that is not common among plasmids core, includes class 1 integrons,

WebJun 1, 2024 · Introduction. Plasmids of the H incompatibility (IncH) complex can be divided into two major Inc groups, IncHI and IncHII [1]. Incompatibility interactions between IncHI and IncHII can be explained by a negative control model: the IncHII repressor binds more strongly to the IncHI operator site than the IncHI repressor binds to the IncHII operator; …
