chromate efflux protein
Overview
High-level chromate resistance in Arthrobacter sp. strain FB24 requires previously uncharacterized accessory genes.
The study identifies three novel genes (chrJ, chrK, and chrL) along with chrA and chrB that contribute to chromate resistance in Arthrobacter sp. strain FB24. These genes are part of a chromate resistance determinant (CRD) and are specifically induced in response to chromate exposure.
Natural hot spots for gain of multiple resistances: arsenic and antibiotic resistances in heterotrophic, aerobic bacteria from marine hydrothermal vent fields.
The study identifies multiple antibiotic and heavy metal resistance genes in marine hydrothermal vent bacteria, highlighting the presence of plasmid-encoded resistance mechanisms and the coexistence of resistance to various metals and antibiotics.
Living in an Extremely Polluted Environment: Clues from the Genome of Melanin-Producing Aeromonas salmonicida subsp. pectinolytica 34melT.
The study identifies several heavy metal resistance genes in Aeromonas salmonicida subsp. pectinolytica 34melT, including merA, copA, arsA, chrA, and zntA, which confer resistance to mercury, copper, arsenite, chromate, and heavy metals respectively.
Identification and Characterization of New Resistance-Conferring SGI1s (Salmonella Genomic Island 1) in Proteus mirabilis.
The study identifies and characterizes five new SGI1 variants in multidrug-resistant Proteus mirabilis strains, highlighting their role in the dissemination of antibiotic and heavy metal resistance genes.
Characterization of an Environmental Multidrug-Resistant Acinetobacter seifertii and Comparative Genomic Analysis Reveals Co-occurrence of Antimicrobial Resistance and Metal Tolerance Determinants.
The study characterizes an environmental multidrug-resistant Acinetobacter seifertii isolate (SAb133) and identifies multiple antimicrobial resistance genes, metal tolerance genes, and virulence factors. Key findings include the presence of bla ADC–25, bla TEM, and various efflux pump genes, along with metal tolerance genes and virulence factors.
First Report of Coexistence of Three Different MDR Plasmids, and That of Occurrence of IMP-Encoding Plasmid in Leclercia adecarboxylata.
The study reports the first identification of three different multidrug-resistant (MDR) plasmids in a single clinical isolate of Leclercia adecarboxylata, including the blaIMP-8 gene encoded on an IMP-encoding plasmid. These plasmids harbor various AMR genes such as blaIMP-8, aacC2, aadA2, mph(A), sul1, qacED1, mer, chrA, dfrA12, tmrB, catA1, catB8, tet(C), blaCTX-M-9, and blaTEM-1.
Genomic analysis of trimethoprim-resistant extraintestinal pathogenic Escherichia coli and recurrent urinary tract infections.
The study identified seven trimethoprim-resistance genes, including dfrA17 and dfrA12, along with bla CTX-M-15 and bla CTX-M-14, which are associated with extended-spectrum beta-lactam resistance. Additionally, the study found chrA, qacEΔ1, and other resistance genes in the analyzed isolates.
Genomic comparisons of Escherichia coli ST131 from Australia.
The study identifies multiple AMR genes and mutations in Australian E. coli ST131 isolates, including bla CTX-M-15 and bla CTX-M-27 for beta-lactam resistance, aadA5, strA, strB, mphA, dfrA17, sul1, qacEΔ1, and chrA for resistance to aminoglycosides, macrolides, trimethoprim, sulfonamides, quaternary ammonium compounds, and chromate. Fluoroquinolone resistance mutations in gyrA and parC were also found.
Roles of the rpoEc-chrR-chrA operon in superoxide tolerance and β-lactam susceptibility of Stenotrophomonas maltophilia.
The rpoEc-chrR-chrA operon contributes to superoxide tolerance and ceftazidime (CAZ) susceptibility in Stenotrophomonas maltophilia. Additionally, the smlt2375-smlt2367 gene cluster, regulated by σ Ec, plays a role in increasing menadione (MD) tolerance and CAZ susceptibility.
