Immunological Studies of Trypsin Treated Epsilon Toxins of C.perfringens Type D,Used in Vaccine Production
Abstract: Different concentrations of trypsin (0.005, 0.01, 0.05,0.1 and 0.3%) were used for activation of epsilon protoxin. The maximum activation was obtained with the concentrations of 0.05, 0.1 and 0.3% as they gave toxicity of 8.000, 10.000 and 10.000 MLD/ml, respictively. Bivalent and polyvalent vaccines produced from theses high batches gave satisfactory antibody titers in immunized sheep.
