It has been proved that the Kazakh sheep with MHC-DRB1 haplotype, Mva Ibc-Sac IIab-Hin1 Iab, had a strong resistance on Cystic ehinococcosis(CE). However, the mechanism is still unclear. It is supposed that disease resistance is closely allied to novel transcripts result from alternative splicing in small intestine tissues. So the PCR-RFLP were employed to select the disease resistant and non-resistant Kazakh sheep. Sheep were grouped as follows: group A, The sheep with the MHC-DRB1 Mva Ibc-Sac IIab-Hin1 Ia...
