FIG. 7.

Effects of autologous primed lymphocytes on killing of macrophages incubated with or without M. avium subsp. paratuberculosis (M. paratuberculosis) or M. avium subsp. avium (M. avium) added. Bovine monocyte-derived macrophages (10⁶) were incubated with autologous primed lymphocytes (10⁷) and with or without gamma interferon. The mean and SE for three separate experiments are shown. Asterisks indicate statistically significant differences relative to control values and M. avium subsp. paratuberculosis values (P < 0.05).
