Figure 1

Images of a scolex with the neck and several immature proglottids obtained from a T. solium tapeworm recovered from the experimental hamster model are seen under contrast phase microscopy or with filters for PI or FITC. The first row corresponds to the section of the scolex-neck and the second row to proglottids. Only results with anti-TSOL18 are included because these, as those with anti-TSOL45-1A or GST, were negative. Magnifications 20×.
