Comparative DNA Analysis of Two vanA Plasmids from Enterococcus faecium Strains Isolated from Poultry and a Poultry Farmer in Norway
Antimicrobial agents and chemotherapy, 2007•Am Soc Microbiol
The DNA sequences of two plasmids carrying vanA, pVEF1 (39,626 bp) and pVEF2 (39,714
bp), were determined. Forty-three shared coding sequences were identified, and the only
nucleotide difference was an 88-bp indel. A postsegregational killing system was identified.
This system possibly explains the persistence of the vanA gene cluster in Norwegian poultry
farms.

Abstract
The DNA sequences of two plasmids carrying vanA, pVEF1 (39,626 bp) and pVEF2 (39,714 bp), were determined. Forty-three shared coding sequences were identified, and the only nucleotide difference was an 88-bp indel. A postsegregational killing system was identified. This system possibly explains the persistence of the vanA gene cluster in Norwegian poultry farms.
