Intestinal washes taken at the indicated time points were analyzed by IgA-specific ELISA and live bacterial flow cytometry and LogEC50 values of IgA E. In contrast PGF mice had a relatively normal albeit attenuated inflammatory response but were less prone to haemorrhage and epithelial injury than GF mice. Germ-free organisms are multi-cellular organisms that have no microorganisms living in or on them.
