The lom gene of bacteriophage λ is involved in Escherichia coli K12 adhesion to human buccal epithelial cells

Abstract

The role of the lom gene of bacteriophage lambda in adhesion of Escherichia coli to human buccal epithelial cells (HBC) was studied testing the adherence of lamda lom+ and lambda lom::TnphoA E. coli lysogens. lambda lom+ prophage increased 50% E. coli adhesion. This effect was not observed with lambda lom::TnphoA. These results suggest that the normal Lom protein participates directly in adhesion or regulates the synthesis of other protein(s), which may be involved in adhesion.
