説明

8157 strains which showed growth with red or pink colonies on the desoxycholate agar were isolated from 108 samples of foods.<BR>These strains were identified by ordinary methods and classified by IMViC test and the results were summarized as follows.<BR>(1) The confidence of detecting ability of this medium seemed to be low in foods (56.4%).<BR>(2) 4649 out of the isolated strains belonged to coliform group organisms, but it was confirmed an ordinary dispersion between their appearance and the source.<BR>(3) 1537 out of the isolated strains (19.2%) were unclassified by IMViC system, and this problem will be discussed in future.
