372.Ascaridiosis is one of the most prevalent helminthoses in fowl. It is caused by various species from the Ascaridia genus. The ascarids have a direct life cycle. Sometimes, it could involve paratenic hosts (earth worms). Infected birds are progressively emaciated, anaemic and sometimes diarrhoeic.
