Publication Multisite Detection of Tn 1549-Mediated vanB Vancomycin Resistance in Multidrug-Resistant Enterococcus faecalis ST6 in Texas and Florida(2023) Simar, Shelby; Tran, Truc; Rydell, Kirsten; Panesso, Diana; Contreras, German; Munita, Jose M.; Cifuentes. Renzo; Abbo, Lilian; Sahasrabhojane, Pranoti; Dinh, An; Axell-House, Dierdre; Savidge, Tor; Shelburne, Samuel; Hanson, Blake; Arias, CesarIn the United States, vanB-mediated resistance in enterococci is rare. We characterized three sequence type (ST) 6, vancomycin-resistant Enterococcus faecalis isolates causing bacteremia in unique patients in spatiotemporally distinct settings. Isolates were recovered between 2018 and 2020 in two cities in the United States (Houston, TX; Miami, FL). The isolates harbored the vanB operon on a chromosomally located Tn1549 transposon, and epidemiological data suggested multiple introductions of the vanB gene cluster into ST6 E. faecalis.
