Effect of GC_(02) coccidiosis vaccine on erythrocyte immune function in chicken

In order to study the influences of GC02 coccidiosis vaccine on the immune function of chicken erythrocyte,a total of 100 one-day-old cross broilers were randomly divided into 2 groups,50 chickens each group,one as control group,the other as experiment group,inoculated with GC02 coccidiosis vaccine,and all the chickens were kept under standard managemental conditions.Every chicken of experiment group was inoculated with 8000 sporulated oocysts of GC02 coccidiosis vaccine at the days of 7 and 14 respectively,and the E-C3bR and E-IC rosette rates of the two groups were tested respectively at the days of 21,28,35and 42.The result showed that after inoculating of GC02 coccidiosis vaccine,there were no significant difference in the E-C3bR and E-IC rosette rates between experiment and control group at the days of 21,28,35 and 42(P0.05).The erythrocyte immune function of chickens was normal after inoculating of GC02 coccidiosis vaccine.
