Comparative genomic analysis of the Hafnia genus reveals an explicit evolutionary relationship between the species alvei and paralvei and provides insights into pathogenicity

tailieu.vn

Comparative genomic analysis of the Hafnia genus reveals an explicit. evolutionary relationship between the species alvei and paralvei and provides insights into pathogenicity. Presence of species-specific core genomes associated with metabolism and transport suggests the putative niche differentiation between alvei and paralvei. These virulence-related profiles identified at the genomic level provide insights into Hafnia pathogenesis and the differentiation between alvei...

Effects of a previously selected antibiotic resistance on mutations acquired during development of a second resistance in Escherichia coli

tailieu.vn

Background: The effect of mutations conferring antibiotic resistance can depend on the genetic background. Results: In a wild-type background, adaptation to any of the antibiotics resulted in the appearance of well-known mutations, as well as a number of mutated genes not known to be associated with antibiotic resistance.. Development of a second resistance in a strain with an earlier acquired...

Dose-dependent impact of oxytetracycline on the veal calf microbiome and resistome

tailieu.vn

Results: In the therapeutic group, OTC levels exceeded MIC values. 16S rRNA gene-based analysis revealed significant changes in the calf gut microbiota. Time-related changes accounted for most of the variation in the sequence data. By metagenomic sequence analysis we identified six antibiotic resistance genes representing three gene classes (tetM, floR and mel) that differed in relative abundance between any of...

doi:10.3906/kim-2011-52. Evaluation of quercetin as a potential β-lactamase CTX-M-15 inhibitor via the molecular docking, dynamics simulations, and MMGBSA. CTX-M-15 is the most common ESBL in Gram-negative bacteria and has been reported in Poland, India, Britain, Bulgaria, Romania, and Turkey. CTX-M-15 has a broad spectrum of β-lactamase activity on various antibiotics and shows high activity against cephalosporins, including cefotaxime and ceftazidime....
