FIG. 7.

Urease activity in the stomachs of conventional BALB/c mice infected with H. felis and treated with LB-SCS or amoxicillin plus omeprazole. Urease activity was measured in the stomachs of mice 29 days postinfection. Each value shown is the mean from 6 or 7 mice (the standard deviations are not shown but were less than 5%). Statistical analysis performed with a Student t test between treatment with the control and LB-SCS or amoxicillin plus omeprazole showed a highly significant difference (P < 0.01).
