| [investigation of plasmid-mediated quinolone resistance determinants in enterobacteriaceae: a multicenter study]. | fluoroquinolones which are in use since 1986, are effective agents both against gram-positive and gram-negative bacteria. quinolones show bactericidal effect as a result of inhibition of dna gyrase and topoisomerase iv enzymes. main quinolone resistance mechanisms are chromosomal mutations in these enzymes and decreased intracellular accumulation due to efflux pumps or decreased membrane uptake. recently a new quinolone resistance mechanism mediated by plasmids has been defined. these plasmids c ... | 2012 | 22951649 |
| identical bacterial populations colonize premature infant gut, skin, and oral microbiomes and exhibit different in situ growth rates. | the initial microbiome impacts the health and future development of premature infants. methodological limitations have led to gaps in our understanding of the habitat range and subpopulation complexity of founding strains, as well as how different body sites support microbial growth. here, we used metagenomics to reconstruct genomes of strains that colonized the skin, mouth, and gut of two hospitalized premature infants during the first month of life. seven bacterial populations, considered to b ... | 2017 | 28073918 |
