This study revealed the dose dependency of prednisolone tertiary-butylacetate (PTBA) treatment on the establishment of Echinococcus multilocularis in the small intestine of Mongolian gerbil (Meriones unguiculatus) and that some of the physiological parameters of host were correlated with the doses of PTBA and establishment of the worm. Twenty Mongolian gerbils were divided into 5 groups, according to the doses of PTBA ; 0mg, 0.5mg, 2mg, 5mg and 10mg per head. All animals were injected intraperitoneally with PTBA every other day from 6 days before to 6 days after infection. Doses of PTBA and the number of worms recovered at 7 days post-infection showed a positive correlation (r=0.929, P<0.0001). The increase of total protein (TP) and the decrease of the percentage of lymphocytes in the peripheral leukocytes were dependent on doses of PTBA (TP : r=0.811, P<0.0001, percentage of lymphocyte : r=-0.92, P<0.0001). The TP and the percentage of lymphocyte also correlated with the number of worms recovered (TP : r=0.617, P=0.0049 ; percentage of lymphocyte : r=-0.800, P<0.0001).
