treatment. However, histological evaluation showed a mild to
moderate degree of inflammation composed of eosinophils,
macrophages, lymphocytes, plasmocytes, and fibroblasts with
connective tissue in the surrounding parenchyma (Figure 1) in
all samples from this group. On the other hand, OFZ killed
100% of cysts in treated pigs, and all animals in this group
showed only degenerated cysts. The inflammatory reaction
around cysts from the OFZ group was severe, and also
demonstrated areas of dystrophic calcification (Figure 2). No
inflammatory reaction was observed in pericystic tissue samples
from pigs in the control group.
