FIG. 5.
Inhibition of parasite antigen secretion by anthelmintic treatment. The levels of parasite antigens in the supernatant of T. solium cysts in culture were assayed by ELISA using MAb B158C11A10 (see Materials and Methods). The graph depicts the mean antigen levels in supernatants from days 1 and 3 of culture, expressed as a ratio of the OD492 values for each test condition to the corresponding control. The differences between days 1 and 3 are statistically significant for ABZ-SO and ABZ-SO plus PZQ (P < 0.05 [Kruskal-Wallis test]).
