Differential PilA pilus assembly by a hospital-acquired and a community-derived Enterococcus faecium isolate.
Pili are hair-like structures protruding from the cell envelope of bacterial cells. Here, we describe the conditional and differential display of PilA-type pili, and PilE and PilF proteins, encoded from pilin gene cluster 1 at the surface of a hospital-acquired Enterococcus faecium bloodstream isolate (E1165) and a community-derived stool isolate (E1039), at two different temperatures. Both str...
متن کاملDetection of an unusual van genotype in a vancomycin-resistant Enterococcus faecium hospital isolate.
We highlight the detection of a rare vanM genotype in Enterococcus faecium. This isolate exhibited a VanB phenotype, with high levels of resistance to vancomycin (MIC, >256 mg/liter) and susceptibility to teicoplanin (MIC, 1 mg/liter). It was, however, vanB negative by PCR. Further screening for other van loci revealed the presence of a complete vanM operon.
متن کاملDisruption of vanS by IS1216V in a clinical isolate of Enterococcus faecium with VanA glycopeptide resistance.
The elements that mediate VanA glycopeptide resistance in enterococci are heterogeneous. Twenty-four distinct VanA elements were identified among a collection of enterococci isolated from hospital patients and nonhuman sources in the United Kingdom (9). Despite their diversity, all these elements showed extensive homology with the prototype VanA transposon, Tn1546, from Enterococcus faecium BM4...
متن کاملComplete Genome Sequence of Enterococcus faecium Commensal Isolate E1002.
The emergence of vancomycin-resistant enterococci (VRE) has been associated with an increase in multidrug-resistant nosocomial infections. Here, we report the 2.614-Mb genome sequence of the Enterococcus faecium commensal isolate E1002, which will be instrumental in further understanding the determinants of the commensal and pathogenic lifestyle of E. faecium.
متن کاملFirst vancomycin-resistant blood isolate of Enterococcus faecium in a children's hospital and molecular analysis of the mechanism of resistance.
The first clinical isolate of vancomycin-resistant Enterococcus spp. in Hacettepe University Children's Hospital was isolated from a blood culture of a patient hospitalized in the intensive care unit. He had been on vancomycin therapy for the last four months for consecutive pneumoniae and sepsis. The isolate was identified as Enterococcus faecium (E. faecium) and minimal inhibitor concentratio...
