Ascaridiasis in peafowl Pavo cristatus (Phasianidae) due to Ascaridia galli Schrank, 1788.

Twelve white peafowl (Pavo cristatus) affected by an outbreak of an intestinal disease were referred for more detailed examination at the Universidade Estadual de Santa Cruz-BA, Brazil. During the course of the disease, peachicks were severely affected, with enteric signs such as diarrhea plus dehydration, decreased feed intake and progressive weight loss. After examination, 8 of 12 samples (66.6%) presented single or mixed nematode infection and Ascarid eggs were the most frequent finding on fecal examination. Adult peafowl did not present clinical signs even when positive after fecal exam. Morphological analysis, clinical signs, fecal and gross examinations resulted in a diagnosis of ascaridiasis caused by Ascaridia galli Schrank (1788).
