| Abstract | ||||
| For studying the effect of cryptosporidiosis on the immune response of ducklings vaccinated with Duck Virus Hepatitis vaccine, 120 one day old, white pekin duckling were divided into 5 groups each of 24 ducklings. Two groups were infected at, one day old and vaccinated at either 1 and 7 days. The other 3 groups were kept as controls (one for infection, one for vaccination and the other as blank). It was found that duckling that were infected and vaccinated showed low level of antibody titer compared to the control group. The prepatent period was 5 days in the 3 experimentally infected groups, whereas the patent varied where it was 23, 24 and 21 days in group I, II and III respectively. | ||||
