The Antibacterial Lectin RegIII-Gamma Promotes the Spatial Segregation of Microbiota and Host in the Intestine

peripheral blood eosinophil count, skin prick tests, and IgE testing. Infants’ microbiota were assessed through collection of fecal samples at 1 and 12 months of life. Polymerase chain reaction fragments from infant stool separated by DGGE (denaturing gradient gel electrophoresis) provided relative assessment of main bacterial strains and were used in assessing variety and richness in microbial genetic diversity. Cultures were used to identify bacteria, fungi, and yeast present in infant stool.
