Abstract

Human milk contains antibodies to a variety of enteropathic agents. We utilized the method of enzyme-linked immunosorbent assay to investigate anti-rotavirus secretory IgA in 113 human milk and colostral specimens from a rural area in Guatemala, 32 colostral specimens from an urban area of Costa Rica, and 12 from an urban area of the United States. Anti-rotavirus SCIgA was found in all colostral samples and in 94% of the milk specimens. Both the absolute concentration of anti-rotavirus SCIgA and concentration relative to total SCIgA were highest in colostrum, falling to lower but detectable levels from one week to two years after birth. No significant differences were noted in the results from the specimens from the three different geographic areas. The possible role of this antibody in immunity to rotavirus infection is discussed.
