IMMUNOGEN COMPOSITIONS FROM EIMERIA ECERVULINA |
摘要 |
High levels of immunity are achieved in chickens inoculated intramuscularly or orally with E. acervulina extract immunogens. These extracts contain at least 20 polypeptides which induce a protective immune response not only against E. acervulina but also against E. tenella and E. maxima. The resulting immunity prevents intestinal lesions and reduces the number of viable oocysts in vaccinated and challenged birds. One or more of these polypeptides can be used as an immunogen to protect against coccidiosis. |
