Bacterial resistance evolution by recruitment of super-integron gene cassettes.
Bacterial resistance evolution by recruitment of super-integron gene cassettes.
Bacterial resistance evolution by recruitment of super-integron gene cassettes.
Bacterial resistance evolution by recruitment of super-integron gene cassettes.
Identification of acquired antimicrobial resistance genes.
The study presents ResFinder, a web-based tool for identifying acquired antimicrobial resistance genes in whole-genome data. It successfully identifies resistance genes with high accuracy and agrees with phenotypic testing. The tool detects various resistance genes across different bacterial species, including beta-lactamases, aminoglycoside modifying enzymes, tetracycline resistance genes, and others.
Diversity of Class 1 Integron Gene Cassette Rearrangements Selected under Antibiotic Pressure.
The study shows that the catB9 gene cassette can be rearranged closer to the Pc promoter under chloramphenicol pressure, enhancing chloramphenicol resistance. This rearrangement occurs through excision of upstream gene cassettes rather than direct relocalization of catB9.
Phenotypic and Genotypic Antimicrobial Resistance Traits of Vibrio cholerae Non-O1/Non-O139 Isolated From a Large Austrian Lake Frequently Associated With Cases of Human Infection.
The study identified beta-lactam resistance genes bla CARB–7 and bla CARB–9, the phenicol resistance gene catB9, and the tetracycline resistance gene tet (34) in Vibrio cholerae non-O1/non-O139 isolates from a large Austrian lake. These genes were associated with resistance to ampicillin, chloramphenicol, and tetracycline, respectively.
Phenotypic and Genotypic Properties of Vibrio cholerae non-O1, non-O139 Isolates Recovered from Domestic Ducks in Germany.
Proximity ligation strategy for the genomic reconstruction of microbial communities associated with the ectoparasite Caligus rogercresseyi.
The study identified four antibiotic resistance genes (ARGs) in the microbiota of the sea louse Caligus rogercresseyi, including tet(35), QnrS2, catB9, and OXA-209, which confer resistance to tetracycline, quinolone, chloramphenicol, and beta-lactam antibiotics, respectively.
Prediction of Antibiotic Susceptibility Profiles of Vibrio cholerae Isolates From Whole Genome Illumina and Nanopore Sequencing Data: CholerAegon.
The study presents CholerAegon, a bioinformatics pipeline for predicting antimicrobial resistance profiles from whole genome sequencing data of Vibrio cholerae. It identifies AMR genes such as dfrA1, sul2, catB9, and floR, and detects mutations like D476N in parE that contribute to fluoroquinolone resistance.
Clinical and Environmental Vibrio cholerae Non-O1, Non-O139 Strains from Australia Have Similar Virulence and Antimicrobial Resistance Gene Profiles.
The study identified antimicrobial resistance genes such as catB9, blaCARB-9, and intSXT in clinical and environmental Vibrio cholerae non-O1, non-O139 strains from Australia, highlighting the presence of multidrug resistance mechanisms in these strains.
Whole Genome Sequencing and Pan-Genomic Analysis of Multidrug-Resistant Vibrio cholerae VC01 Isolated from a Clinical Sample.
The study identified multiple AMR genes in the multidrug-resistant V. cholerae VC01 strain, including catB9, floR, tet(34), sul2, and dfrA1, which confer resistance to chloramphenicol, florfenicol, oxytetracycline, sulfonamide, and trimethoprim, respectively.
Complete genome sequence and comparative analysis of a Vibrio vulnificus strain isolated from a clinical patient.
Emergence of multidrug resistant, ctx negative seventh pandemic Vibrio cholerae O1 El Tor sequence type (ST) 69 in coastal water of Kerala, India.
The study identifies multidrug-resistant Vibrio cholerae O1 El Tor sequence type 69 in coastal waters of Kerala, India, which lacks the ctx gene but contains several antimicrobial resistance genes including sul2, dfrA1, strA, strB, parC, parE, catB9, and floR.
Surveillance of travel-associated isolates elucidates the diversity of non-pandemic Vibrio cholerae.
The study identified various AMR genes in travel-associated V. cholerae isolates, including catB9, floR, sul2, and tetA, which confer resistance to chloramphenicol, sulfonamide, and tetracycline. These genes were detected in both 7PET and non-7PET lineages.
Antimicrobial resistance and virulence factors analysis of a multidrug-resistant Acinetobacter baumannii isolated from chickens using whole-genome sequencing.
The study identified 41 antimicrobial resistance genes in the multidrug-resistant Acinetobacter baumannii Y03 isolate, including genes conferring resistance to beta-lactams, phenicols, macrolides, lincosamides, aminoglycosides, and nitrofurans.
Vibrio cholerae endemic to the lower Rio Grande Delta segregate into urban and rural phylotypes.
Urban V. cholerae isolates from the lower Rio Grande Delta (LRGD) exhibit resistance to beta-lactam antibiotics due to the presence of the CARB-7 beta-lactamase gene, while rural isolates show variations in OmpU expression and lack certain virulence factors.
Genomic diversity and antimicrobial resistance of Vibrio cholerae isolates from Africa: a PulseNet Africa initiative using nanopore sequencing to enhance genomic surveillance.
The study identified a high prevalence of trimethoprim resistance genes (dfrA1, dfrA15, dfrA31) and other resistance genes such as floR, strA, strB, varG, blaCARB-2, aadA1, aadA2, sul1, sul2, catB9, tet(C), tet(G), tet(59), qacEdelta, and blaCMY-4 in Vibrio cholerae isolates from Africa. Fluoroquinolone resistance mutations (gyrA_S83I and parC_S85L) and nitrofuran resistance mutations (nfsA_R169C and nfsB_Q5*) were also prevalent.
