Recent reports from hospitals of infectious diarrhea in the new-born present a baffling bacteriologic picture. Barenberg, Levy and Grand1 reported four epidemics of this type of infection which occurred within a year in hospitals of New York city and the near vicinity. The mortality averaged around 50 per cent. In none of these epidemics could one be sure of the causative agent.
Dulaney and Michelson2 reported a succession of cases of diarrhea in the new-born at the Memphis General Hospital in which 47 per cent of the patients died. In this epidemic 67 per cent of the babies had stools containing Bacterium coli-mutabile. It may berecalled that the interesting characteristic of this organism is its similarity to the Salmonella, or paratyphoid, group. The organism when first isolated appears to be a true member of the Salmonella family. Dissociation then occurs if the culture is made on a medium
