  1. Adhesion, invasion, intra-macrophage replication, and biofilm formation indices are specified. Abbreviators: AIEC: AIEC phenotype (+: strains that adhere to and invade Intestine-407 cells and that were able to survive and/or replicate within J774 macrophages in vitro); I_ADH: adhesion index; I_INV: invasion index; I_REPL: replication index; SBF: specific biofilm formation index; BFC: Biofilm formation category; W: weak biofilm producer; M: moderate biofilm producer; and S: strong biofilm producer.
