A kinetic in vitro study of cell mediated immunity (C.M.I.) has been made in the turkey and the chicken experimentally infected with Syngamus trachea. The method used for this purpose was an indirect test based on the inhibition of macrophage spreading. In the turkey, C.M.I. appeared by the 4th day following the infection, reached its maximum by the 15th day, then decreased slowly and disappeared by the 13th week. Reinfection induced a C.M.I. significantly greater than those observed in the case of a single infection. In the chicken also, C.M.I. appeared by the 1st week but its maximum was reached earlier and had disappeared as early as the 5 th week. The results we have observed are in agreement with those previously reported in other parasitic models such as schistosomiasis caused by Schistosoma mansoni and trichinellosis.
