FIG. 3.

PCR-RFLP profiles of Bacteroides and Prevotella strains from different sites in the pig hindgut digested with restriction endonuclease HhaI. Regions of extracted DNA are denoted as colonic (Co) lumen (L), wall (W), and wall surface (S) and cecal (Ca) lumen. The reference strains are as follows: lane 1, Prevotella ruminicola 23; lane 2, Prevotella albensis M384; lane 3, Bacteroides uniformis 1100; lane 4, Bacteroides thetaiotaomicron 5482. Some residual uncut material is present in lane 4.
