Selection of strains of Poultry Eimeria sporozoites through extra - intestinal

摘要

A method to obtain a useful immunogenic Strain to produce a Vaccine against coccidiosis infection Cycle includes at least a First Group of donors with specific pathogen free Birds of a species of Eimeria oocytes. Then, It collects Blood Donors of these Birds, and then used to Infect a second group of Specific Pathogen Free Chickens.Oocytes were collected from the second group of Birds. These oocytes are then multiplied to complete the Cycle. Then the cycle is repeated using oocytes multiplied. After a total of approximately three cycles, an Antigen can be collected and used as a source to generate oocytes for a vaccine.Claim: (1) a Strain isolated oocytes to generate useful immunogens for Vaccination against coccidiosis. Claim (3): an effective Vaccine against coccidiosis comprising at least approximately 104 Eimeria oocytes per dose attenuated, together with a pharmaceutically acceptable Carrier. Vindication (27): Eimeria oocytes derived from acervulina, and such.Acervulina attenuated by approximately three cycles of Passage through specific pathogen free Chickens. Vindication (28): a Eimera strain that has the characteristics of the strain and immunogenic.Acervulina deposited in the European Collection of Cell Cultures under the Access Number 02010911 Claim (29) taking the vaccine: a vaccine Antigen Response Properties of a Vaccine against coccidiosis inmunogenizante containing a number of oocytes obtained from the CEP To e.Acervulina deposited in the European Collection of Cell Cultures under the Access Number 02010911
