Infectious Agents in Infant Diarrhea: I. A Hemagglutination-Inhibition Procedure for Detection of Bacterial Fractions in Infant Sera

Abstract

Infants with diarrhea do not always respond with a rise in antibody titer against the infecting organism. By means of a simple hemagglutination-inhibition test, described in detail, inhibitors have been detected in the sera of such patients. These inhibitors are antigenically related to, and possibly derived from, the bacteria isolated from the infants'' intestine at the time diarrhea occurs.
