Under a magnification of 400X, this 1982 micrograph, reveals some of the ultrastructural details exhibited by an unfertilized egg of the round worm, Ascaris lumbricoides. Fertilized Ascaris lumbricoides eggs are rounded, and have a thick shell (PHIL_410). While unfertilized eggs like this one, are elongated, and larger, thinner shelled, covered by a more visible mammillated layer, which is sometimes covered by protuberances, as in this case.
