These worms are large and typically appear thick, with a yellowish-white coloration. They primarily parasitize the small intestine of susceptible hosts, occasionally infecting the ceca as well. Female Ascaridia worms tend to be larger than males. These parasites follow a simple, direct life cycle. The eggs they produce are nonembryonated, elliptical, and have a thick shell. They contain fine granular brownish contents and have a colorless outer shell. These eggs are excreted in the host’s feces and require appropriate humidity and temperature in the environment to embryonate, a process that typically takes 2 to 3 weeks.
