From: Mutational and transcriptional analyses of an avian pathogenic Escherichia coli ColV plasmid
Strain or Plasmid | Relevant Characteristicsa | Reference and/or Source |
---|---|---|
APEC O2 | Virulent to chick embryos; contains pAPEC-O2-ColV and pAPEC-O2-R | Diseased Chicken [1–3] |
pAPEC-O2-ColV | ColV plasmid of APEC O2; contains iss, tsh, and traT genes, along with the aerobactin, ColV, sit and iro operons | [1,3] |
pAPEC-O2-R | R plasmid of APEC O2; encodes resistance to multiple antimicrobial agents | [2,3] |
NC | Relatively avirulent to chick embryos and lacks iss, tsh, and the aerobactin, ColV, and iro operons | Healthy Chicken [3] |
NC/pAPEC-O2 | Transconjugant derivative of NC containing pAPEC-O2-ColV and pAPEC-O2-R; has enhanced abilities to kill chick embryos and grow in human urine relative to strain NC | [3] |
pKD46 | ampR ; temperature sensitive plasmid which expresses the λ Red recombinase proteins when induced by arabinose | [30] |
pSKY5000 | camR derivative of pKD46 | [42] |
