Phylogenetic analysis showed that the Gp38 adhesin of phages AV119, AV120, and AV121 are most closely related to Gp38 of phage AV111 dependent on OmpA and LPS for infection, suggesting that these phages depend on both receptors for infection of ECOR4 (Figures 5A and 5C). The gene discussed is PDPN; the disease is infection.
