Description:These are 3 fertilized A. lumbricoides eggs with the one on the right being decorticated, for its outer layer is absent.
After fertile eggs embryonate, they become infective after 18 days to several weeks. If ingested, larvae, i.e., immature worms, can hatch, causing the intestinal infection “Ascariasis”, which infects children more often than adults.
