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.
Population genomics of the food-borne pathogen Vibrio fluvialis reveals lineage associated pathogenicity-related genetic elements.
The study identified 21 antimicrobial resistance genes in Vibrio fluvialis, with 19 of them predominantly present in VflPop2. The tetracycline resistance gene tet(35) was found in 95% of VflPop2 strains, highlighting its significance in the population. Additionally, the plasmid pBD146 was associated with resistance to trimethoprim-sulfamethoxazole, and the presence of dfr6 gene in pBD146 was linked to this resistance.
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.
