The intestine appears darker beside the two sections of the uterus. (Magnification × 40) 5B: Section of the same onchocercoma as seen in 5A. The nucleus (nc) is visible in the hypodermis. Intact microfilariae (mf) and pretzel stages (pz) are shown. (Magnification × 60) 5C: Part of the hypodermis and the cuticle of a female adult O. volvulus.
