Enterococci were obtained from 410 samples (45.2%) of 906 various poikilothermal materials. Of these samples examined, enterococcal strains were isolated at fairly high level (70%) from intestinal contents of fish and insects, while they were not frequently detected from those of frogs, plants and soils.
The bacterial counts of enterococci in certain samples tested were at the level from 103 to 105 per g.
The classification method for enterococcus group reported by Shimazaki et al. was used in this stndy.
According to biological properties, the majority of the isolated strains were identified as the type B-II (Str. faecium). Most of the remainders were classified as the type A-II (Str. faecalis and Str. faecalis var. liquefaciens), and only a few strains showing the beta-haemolysis were isolated.
Furthermore, some strains among the isolated could not be clearly classified.
