Abstract
SUMMARY A new technique to study the prevalence of circulating antibodies directed against different morphological groups (‘morphotypes’) of bacteria in fresh faeces is presented. The technique combines quantitative indirect immunofluorescence with digital image analysis. Plasma antibody titres and patterns of IgA, IgG and IgM isotype against morphotypes of faecal bacteria were determined in ten healthy individuals.
