OBJECTIVES To investigate the presence and the genetic environment of the multiresistance gene cfr in naturally occurring Gram-negative bacteria of pigs. METHODS A total of 391 bacterial isolates with florfenicol MICs of ≥16 mg/L, obtained from 557 nasal swabs of individual pigs, were screened by PCR for the known florfenicol resistance genes. The species assignment of the cfr-carrying isolat...
Tn5385 is a ca. 65-kb element integrated into the chromosomes of clinical Enterococcus faecalis strains CH19 and CH116. It confers resistance to erythromycin, gentamicin, mercuric chloride, streptomycin, tetracycline-minocycline, and penicillin via beta-lactamase production. Tn5385 is a composite structure containing regions previously found in staphylococcal and enterococcal plasmids. Several ...
Antibiotic resistance is a worldwide public health concern. Conjugative transfer between closely related strains or species of bacteria is an important method for the horizontal transfer of multidrug-resistance genes. The extent to which nanomaterials are able to cause an increase in antibiotic resistance by the regulation of the conjugative transfer of antibiotic-resistance genes in bacteria, ...
BACKGROUND Dissemination of antimicrobial resistance genes has become an important public health and biodefense threat. Plasmids are important contributors to the rapid acquisition of antibiotic resistance by pathogenic bacteria. PRINCIPAL FINDINGS The nucleotide sequence of the Klebsiella pneumoniae multiresistance plasmid pMET1 comprises 41,723 bp and includes Tn1331.2, a transposon that ca...
