Action mechanism of blood cell immune response in water buffaloes against acute infection with F. Hepatica was studied. The results showed that after water buffaloes were infected, the total levels of WBC surpassed control group during whole infection period; Eosinophiles (%) of DC were higher than control group at the 2nd week until 19th week, and then dropped and was close to control group; Neutrophiles(%)was low or significantly lower than control group within the 5 - 16th weeks; The total levels of lymphocytes (%) was lower than control group during the whole infection period; T-lymphocytes (%) dropped significantly, but B-lymphocytes(%) had opposite changes from the first week of infection, and they were close to the control group after 11 weeks; RBC-CR1 and RBC-IC rosette rates dropped and rose during 2 - 16 and 2- 18 weeks, respectively, and then approached the same between both groups. It was suggested that the violent changes of specific and nonspecific immune responses in water buffaloes with acute F. hepatica infection are related with the mechanism against infection with F. hepatica together.
