THE “BULGARIAN BUG.”
SCIENTIFIC RESEARCHES
BACTERIAL FRIENDS AND FOES.
A communication appears in a late number of the Dublin Journal of Medical Science, by Dr. J. C. Johnson, entitled “Bacterial Symbiosis.” It contains a reference to the kephirgrain, known as the Bulgarian bug. In view of the interest attaching to the soured-milk treatment, it may be noted that the kephirgrain is mentioned as an example of symbiosis, i.e., two .organisms, mutually helpful, living side by side, in this case a yeast and a bacillus. Among moulds and bacteria this condition is somewhat unusual, as “the action of two such species grown in the same culture medium is mutually antagonistic and destructive.” How each helps the other ’is not cpiite clear.
Professor Marshall Ward holds that the products of one bacterium may simulate the other by containing “some body which a els as an exciting drug to the other.” Organisms are coupled symbiotically in the “rising” of yeast bread, maturation of wines, and formation of rice bi’andies of Oriental nations..
