Journal ArticleDOI
Vancomycin-resistant enterococci isolated from animals and food.
TL;DR: The high rate of colonization of chicken products by vanA containing enterococci detected 6 months to 1 year after the banning of avoparcin as a growth promoter, supports other studies suggesting that the food chain could be a source of VRE colonization in humans and thus a sourceof VRE infections.
Journal ArticleDOI
Rapid Identification of Enterococcus hirae and Enterococcus durans by PCR and Detection of a Homologue of the E. hirae mur-2 Gene in E. durans
Cesar A. Arias,Beatriz Robredo,Kavindra V. Singh,Carmen Torres,Diana Panesso,Barbara E. Murray +5 more
TL;DR: PCR using primers for two genes (copY and murG) of E. hirae strains showed amplification with E. durans strains only, and PCR (under high-stringency conditions) withPrimers for the mur-2ed gene gave the expected amplification product only with E.'s durans strain.
Journal ArticleDOI
From vanA Enterococcus hirae to vanA Enterococcus faecium: a study of feed supplementation with avoparcin and tylosin in young chickens.
Beatriz Robredo,Kavindra V. Singh,Fernando Baquero,Barbara E. Murray,Barbara E. Murray,Carmen Torres +5 more
TL;DR: The data suggest that E. hirae may be a significant source of vanAdeterminants with the potential of transfer to other enterococcal species from humans or animals, and the level of glycopeptide resistance was higher in the transconjugants than in the donor E. Hirae strains.
Journal ArticleDOI
Tn1546 structures and multilocus sequence typing of vanA-containing enterococci of animal, human and food origin
María López,Yolanda Sáenz,Míriam J. Álvarez-Martínez,Francesc Marco,Beatriz Robredo,Beatriz Rojo-Bezares,Fernanda Ruiz-Larrea,Myriam Zarazaga,Carmen Torres +8 more
TL;DR: A moderate variability in Tn1546 structure has been detected among unrelated vanA-containing enterococci of different origins, showing three new structures including two new ISs.
Journal ArticleDOI
Streptogramin resistance and shared pulsed-field gel electrophoresis patterns in vanA-containing Enterococcus faecium and Enterococcus hirae isolated from humans and animals in Spain.
TL;DR: Based on the presence of indistinguishable PFGE patterns among VR E. faecium and E. hirae from humans and chickens, it is concluded that horizontal transfer of these strains could occur between both groups.
