Overview
Aeromonas hydrophila AmpH and CepH beta-lactamases: derepressed expression in mutants of Escherichia coli lacking creB.
Biofilm Formation Potential of Heat-Resistant Escherichia coli Dairy Isolates and the Complete Genome of Multidrug-Resistant, Heat-Resistant Strain FAM21845.
The study identified multiple antimicrobial resistance genes in the multidrug-resistant, heat-resistant E. coli strain FAM21845, including beta-lactamase blaTEM-1, aminoglycoside resistance genes strA, strB, aadA1, aph(3')-Ic, aph(4)-Ia, aac(3)-IVa, sulfonamide resistance gene sul1, trimethoprim resistance gene dfrA1, tetracycline resistance gene tet(B), disinfectant resistance gene qacEΔ1, and biofilm-related genes mrkABCDF. Additionally, the strain carried genes for resistance to arsenic, silver, and copper.
Aeromonas caviae mimicking Vibrio cholerae infectious enteropathy in a cholera-endemic region with possible public health consequences: two case reports.
The study identified Aeromonas caviae causing cholera-like symptoms, which was initially mistaken for Vibrio cholerae. The isolates carried genes encoding resistance to beta-lactam, sulfonamide, and trimethoprim.
Acquisition and dissemination of cephalosporin-resistant E. coli in migratory birds sampled at an Alaska landfill as inferred through genomic analysis.
The study identified various beta-lactam resistance genes, including bla CTX-M-55, bla CTX-M-14, and bla CMY-2, in cephalosporin-resistant E. coli isolates from gulls and bald eagles in Alaska. These genes were found to confer resistance to beta-lactam antibiotics.
Forensic genomics of a novel Klebsiella quasipneumoniae type from a neonatal intensive care unit in China reveals patterns of colonization, evolution and epidemiology.
The study identifies two beta-lactamase genes, ampH and blaOKP-B-10, in the novel ST2727 strain of Klebsiella quasipneumoniae subsp. similipneumoniae, which contribute to antimicrobial resistance.
Acquisition and loss of CTX-M plasmids in Shigella species associated with MSM transmission in the UK.
The study identifies the presence of bla CTX-M-27, erm(B), mph(A), aph(3')-Ib, aph(6)-Id, sul2, and tet(A) in Shigella isolates associated with MSM transmission in the UK, highlighting the role of plasmids in the spread of antimicrobial resistance.
Mucilaginibacter sp. Strain Metal(loid) and Antibiotic Resistance Isolated from Estuarine Soil Contaminated Mine Tailing from the Fundão Dam.
The study identifies multiple AMR genes in Mucilaginibacter sp. 21p, including genes for resistance to quinolones, aminoglycosides, beta-lactamases, sulfonamides, tetracyclines, daptomycin, arsenic, zinc, manganese, cobalt, and cadmium. These genes are part of efflux pumps and other resistance mechanisms, indicating the strain's adaptability to metal(loid) and antibiotic stressors in contaminated environments.
Differential response to prolonged amoxicillin treatment: long-term resilience of the microbiome versus long-lasting perturbations in the gut resistome.
The study found that prolonged amoxicillin treatment leads to an increase in the abundance and diversity of antimicrobial resistance genes (ARGs) in the gut microbiome, particularly beta-lactamase genes such as cfxA and its variants, as well as tetracycline and macrolide resistance genes.
In Vitro Microevolution and Co-Selection Assessment of Florfenicol Impact on Escherichia coli Resistance Development.
Florfenicol exposure leads to increased resistance to fluoroquinolones and cephalosporins through mutations in efflux pump genes such as acrB, acrR, emrR, and robA, as well as the presence of resistance genes like ampC, ampH, bacA, and emrB.
Potential involvement of beta-lactamase homologous proteins in resistance to beta-lactam antibiotics in gram-negative bacteria of the ESKAPEE group.
The study identifies and characterizes beta-lactamase homologous proteins in gram-negative bacteria of the ESKAPEE group, highlighting their potential role in resistance to beta-lactam antibiotics.
Genomic analysis of Enterobacteriaceae from colorectal cancer patients at a tertiary hospital in Ghana: a case-control study.
The study identified various antimicrobial resistance genes in Enterobacteriaceae isolated from colorectal cancer patients and healthy controls, including ampC2, ampH, strA, strB, mphA, sul1, sul2, tetA, tetR, and dfrA14.
Genomic features, antimicrobial resistance and pathogenicity assessment of Escherichia coli serotype O177:H51 strain JS01 isolated from a diseased chicken.
The study identified 64 AMR genes and 177 virulence factor genes in the E. coli strain JS01, highlighting its multidrug resistance and high pathogenicity.
Regulatory relationships among aldB, ampH, and acoR and their impact on β-lactam susceptibility in Phytobacter diazotrophicus.
The study identifies aldB, ampH, and acoR as key regulators of β-lactam resistance in Phytobacter diazotrophicus, demonstrating that aldB and acoR reduce resistance by upregulating ampH and aldB expression, respectively.
Resistance evolution under potentiated sulphonamide pressure in Escherichia coli.
The study identified multiple antimicrobial resistance genes and mutations in E. coli under potentiated sulphonamide pressure, highlighting the role of efflux pumps and folate pathway modifications in resistance development.
