From: Lsr operon is associated with AI-2 transfer and pathogenicity in avian pathogenic Escherichia coli

Tissue and organAPEC strainsFold change

Bacteria in liver (CFU/g)5.9 × 1083.6 × 1051639↓
Bacteria in spleen (CFU/g)1.9 × 10106.0 × 105316 667↓
Bacteria in kidney (CFU/g)6.1 × 1088.1 × 105735↓
  1. “↓” means the fold change of bacterial loads of APEC94Δlsr(Cm) in infected animals decreased compared with APEC94.
