Much has been said concerning the intestinal flora of infants, both breast fed and bottle fed, but owing to the intangibility of certain aspects of the subject, the field seems to be open to further investigation.Description of the bacteriology of breast fed babies' stools which have been published heretofore are based chiefly on small groups, on very young infants in maternity wards, or on diseased babies. In the Research Laboratories of The Boston Floating Hospital, during the past year, we have had an unusual opportunity in connection with certain metabolism investigations for studying a fairly large group of normal breast fed babies of different ages.The work here described has been undertaken as an independent research subject although no claims are made as to its originality. Its chief aim has been to obtain complete bacteriologic data as a parallel to metabolism work done simultaneously on the same babies.
