Types of ova (A. Lumbricoides)
Unfertilized (left) and fertilized (right) Ascaris lumbricoides eggs. The unfertilized eggs are longer and narrower than fertilized eggs, measuring 75-85µm by 35-50µm wide. The fertilized eggs have a thick and bumpy outer wall which is stained golden brown with bile. (Saline wet prep) (SOURCE: PHIL 411/4821 - CDC/Dr. Mae Melvin)

Note the gross features of the typical, unembryonated, fertilize egg, ie, the bile-stained, thick, smooth shell with polar prominences, often called polar “plugs.”

This illustration demonstrates the gross features of male and female adult worms. Note that both are whip-like, that the male, in contrast to the female, has a characteristically coiled tail. These worms, though small, are readily seen but rarely found in feces, except following treatment.

Enterobius VermicularisPurely UST Slides
Enterobius vermicularis (adult male) Adult male worms are much smaller than females and are detected less frequently in feces or on cellulose tape. The oral end lacks a true buccal capsule but is provided with three lips and dorsoventral bladder-like expansion of the cuticula. Note the posterior end strongly curved ventrad. It has a single conspicuous copulatory spicule.
Enterobius vermicularis (adult male) Higher magnification of the posterior end of the adult male showing strongly curved ventral end and the conspicuous copulatory spicule.
Female and male adult worms.
The female worms of E. vermicularis (pinworm) is white and measures from 8 to 15 mm in length by approximately 0.4 mm in width. In contrast, the male adult worm is much smaller, measuring 2 to 3 mm in length by 0.1 to 0.2 mm in width. The dilated cephalic region is similar in both sexes, while the tail is pointed in the females (left) and blunted in the males (right).
Clear adhesive tape applied to the perianal area of a child reveals numerous football – shaped Enterobius vermicularis embryonated ova. Scratching the perianal area leads to hand contamination with infected ova and retroinfections of the host.
