Colistin-resistant Escherichia coli belonging to different sequence types: genetic characterization of isolates responsible for colonization, community- and healthcare-acquired infections

Intestinal colonization with multidrug-resistant Enterobacterales: screening, epidemiology, clinical impact, and strategies to decolonize carriers

“…In particular, community-onset infections due to ESBL-Ent were increasingly being reported in the early to mid-2000s, while reports about community-associated CRE infections started to emerge around 2010 [82,83]. More recently, there have also been an increasing number of reports for communityassociated COL-R isolates that simultaneously possessed resistance mechanisms against other antimicrobials such as carbapenems, 3GCs, and aminoglycosides [84][85][86].…”

Hybrid genome assembly of colistin-resistant mcr-1.5-producing Escherichia coli ST354 reveals phylogenomic pattern associated with urinary tract infections in Brazil

“…In silico analysis based on MLST, Clermont typing, serotype, and fimH subtyping revealed that E. coli strain 14005RM belonged to ST354, phylogroup F, O153:H34, and fimH38 , respectively. The ST354 has been globally recovered from human, animal, soil, and raw vegetable samples [8 , 9 , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] ], supporting its potential for dissemination and adaptation to different settings and representing a One Health concern. Noteably, previous studies also reported phylogroup F E. coli ST354 causing human bloodstream and urinary tract infections (UTIs) in China [21] and Brazil [22] , as well as UTIs in a dog in Thailand [23] .…”

Noteably, previous studies also reported phylogroup F E. coli ST354 causing human bloodstream and urinary tract infections (UTIs) in China [21] and Brazil [22] , as well as UTIs in a dog in Thailand [23] . In this regard, the high ability to infect both the bladder and the kidney of phylogroup F isolates has also been reported [20] .…”

Identification of mcr-1 Genes and Characterization of Resistance Mechanisms to Colistin in Escherichia coli Isolates from Colombian Hospitals

“…IncI2 plasmids are considered important drivers of the rapid mobilization and acquisition of mcr genes [ 46 ]. In fact, a recent study observed significant geographic clustering in the regional spread of mcr-1 -bearing IncI2 plasmids in Asia and Brazil [ 47 , 48 ].…”
