Description: Caption:
This photomicrograph reveals ultrastructural details exhibited by an embryonated Ascaris lumbricoides egg with no outer mammillated layer, which makes this a decorticated ovum. Embryonated, fertilized eggs, become infective after 18-days to several weeks. If ingested, larvae can hatch from the eggs and cause intestinal infection, which infects children more often than adults.
