membrane-spanning domain of a homodimeric ABC transporter
Overview
Acquired bacitracin resistance in Enterococcus faecalis is mediated by an ABC transporter and a novel regulatory protein, BcrR.
The study identifies the bcrABD operon and the regulatory gene bcrR as essential for acquired bacitracin resistance in Enterococcus faecalis. The bcrABD genes encode a homodimeric ABC transporter that mediates bacitracin efflux, and bcrR acts as a transcriptional activator of this operon.
Characterization of genes encoding for acquired bacitracin resistance in Clostridium perfringens.
The study identifies and characterizes the bcrABDR operon in Clostridium perfringens, which includes genes encoding an ABC transporter (bcrA, bcrB), an undecaprenol kinase (bcrD), and a regulatory gene (bcrR) associated with high-level bacitracin resistance.
Characterization of Multi-Drug Resistant Enterococcus faecalis Isolated from Cephalic Recording Chambers in Research Macaques (Macaca spp.).
The study identified various AMR genes and mutations in Enterococcus faecalis isolates from macaque cephalic implants, highlighting the presence of high-level aminoglycoside resistance, tetracycline resistance, and bacitracin resistance. These findings emphasize the complexity of AMR in clinical settings and the need for targeted antimicrobial strategies.
Genomic insights into the pathogenicity and environmental adaptability of Enterococcus hirae R17 isolated from pork offered for retail sale.
The study identified multiple antimicrobial resistance genes in Enterococcus hirae R17, including genes conferring resistance to beta-lactam antibiotics, lincosamides, streptogramins, pleuromutilins, polymyxins, tetracyclines, and others. Notably, the strain exhibited resistance to bacitracin, ciprofloxacin, daptomycin, erythromycin, and tetracycline.
Agricultural Origins of a Highly Persistent Lineage of Vancomycin-Resistant Enterococcus faecalis in New Zealand.
The study identifies the ST108 lineage of vancomycin-resistant Enterococcus faecalis as having an agricultural origin, with multiple resistance genes including vanA, ermB, tetL, tetM, and bcr operon components contributing to its persistence in New Zealand.
Surveillance of Enterococcus spp. reveals distinct species and antimicrobial resistance diversity across a One-Health continuum.
The study identified several AMR genes in Enterococcus spp., including erm(B), tet(M), optrA, dfrE, lsa(A), aac(6')-Ib, eat(A), ant(6)-Ia, aph(3')-IIIa, sat4, tet(L), bcrB, bcrC, dfrF, and dfrG, which confer resistance to various antibiotics such as macrolides, tetracyclines, oxazolidinones, trimethoprim, and aminoglycosides.
Biocide-tolerance and antibiotic-resistance in community environments and risk of direct transfers to humans: Unintended consequences of community-wide surface disinfecting during COVID-19?
The paper discusses the mechanisms of biocide tolerance and antibiotic resistance in bacteria, highlighting the role of mutations, horizontal gene transfer, efflux pumps, membrane alterations, and biofilms in developing resistance to disinfectants and antibiotics. It emphasizes the risks posed by the extensive use of disinfectants during the COVID-19 pandemic and the potential for increased antimicrobial resistance.
Genomic characterization of Bacillus cereus sensu stricto 3A ES isolated from eye shadow cosmetic products.
The study identified several antimicrobial resistance (AMR) genes in B. cereus s.s. 3A-ES, including VanB-type, VanRB, CAT15/16, BcrA, BcrB, Lsa(B), and recA, which contribute to resistance against various antibiotics and preservatives in cosmetic products.
