Immunopathological results of colonic biopsies in cryptosporidiosis and controls
| Cryptosporidiosis (group I) | AIDS without intestinal infection (group II) | Control (group III) | |
|---|---|---|---|
| Phenotypic analysis of infiltrating lymphoid cells within the lamina propria and surface epithelium. Values are expressed as percentage of cells of phenotype shown as a subset of all nucleated cells within six representative grids (lamina propria) or cells of phenotype/100 epithelial cells (surface epithelium). | |||
| Values are means (SE) of samples. | |||
| Cryptosporidiosis v HIV negative controls: *, p <0.001; **, p <0.00001. | |||
| Cryptosporidiosis v AIDS without intestinal infection: §, p <0.05; §§, p <0.01; §§§, p <0.0001. | |||
