RESUMEN
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).

The aim of this work was to analyze the content of total protein and nitrogen degradation products in Biomphalaria glabrata infected with Schistosoma mansoni and exposed to Euphorbia splendens var. hislopii latex. The LC(50) of this latex was 1.0mg/l. Concentrations of uric acid, urea and total proteins were determined in the hemolymph of B. glabrata infected with five S. mansoni miracidia and exposed to a sublethal concentration of E. splendens var. hislopii latex for 24h. The exposure to this molluscicide caused total depletion of the alterative sources of energy (total proteins) and significant variation in the nitrogen degradation products. The urea content increased while the uric acid level decreased. These results reflect a disturbance in the snails regulation of their metabolism due to intoxication caused by the latex exposure.
