Abstract

Jejunal biopsies from volunteers challenged with Cryptosporidium parvum were examined for tumor necrosis factor alpha (TNF-α) and interleukin (IL)-1β mRNA. Postchallenge biopsies from 15 of 28 (54%) volunteers expressed TNF-α; 14% expressed IL-1β. Cytokine expression did not correlate with enteric symptoms, suggesting that TNF-α and IL-1β are not key mediators of diarrhea in human cryptosporidiosis.
