    The immune response in the stomach mucosa during the primary infection and re-infection with Cryptosporidium muris (TS03 and CB03) in immunocompetent BALB/c mice was characterized using flow cytometry analysis and measurement of IFN-gamma and IL10 by enzyme-linked immunosorbent assays (ELISA). Significantly, elevated migration of T lymphocytes (more than 1,000-fold), especially CD8+ T lymphocytes, to the stomach mucosa occurred during primary infection and persisted for more than 2 months after its resolution. The ex vivo cultures of splenocytes revealed very low levels of IFN-gamma production during the course of the primary infection (0.5 ng/ml), whereas in the following re-exposure to the parasites, the concentration of IFN-gamma rapidly increased 22-fold. These results imply that the CD8+ T lymphocytes are involved in the immune response to gastric cryptosporidiosis and could play an important role in the elimination of C. muris infection in mice.
