Faeces samples from a total of 397 presumably healthy students in Norway were collected during April to September, 1979. Twenty strains of Y. enterocolitica and Y. enterocolitica ‐like bacteria were isolated from 10 (3%) of these students. Six students harboured 2–4 antigenically distinct strains. Of the total of 20 strains, 14 were typical Y. enterocolitica isolates, representing five different serogroups (4, 5, 6, 7–8, 13–7 and non‐agglutinable). The remaining six strains were tentatively designated Y. enterocolitica ‐like bacteria. They showed atypical reactions with respect to one or more of the following characters: fermentation of rhamnose, sucrose, cellobiose and sorbose. The strains recovered from healthy humans in this work were similar to strains previously isolated from wild‐living mammals, fish and water in Scandinavia. Nine strains produced enterotoxin at 22°C but not at 37°C.
