Here, we mentioned that representative six genes (ANPEP; Alanyl Aminopeptidase, Membrane, BGLAP; Bone gamma-carboxyglutamic acid-containing protein, CMC4; C-X9-C Motif Containing 4, COL1A1; Collagen Type I Alpha 1 Chain, COL1A2; Collagen Type I Alpha 2 Chain, SLC14A2; Solute Carrier Family 14 Member 2) which showed highest expression change (down regulation) with fold change (log2) of ‘ <−2.0’ on at least two infection groups. The gene discussed is COL1A1; the disease is infection.
