Numerous inflammatory cells are recruited in response to Cryptosporidium parvum infection. These cells include interferon gamma-producing T lymphocytes, which are of major importance for the resolution of infection. Here, we show that ß7 integrin is not essential for the control of infection in mice but that ß7-deficient neonatal mice are more susceptible during the early stages of infection.
