The status of nitric oxide oxidation products and antioxidant vitamins were investigated in goats infected with endoparasites and blood parasites (Trichostrongylidae sp. + Protostrongylidae sp. + Eimeria sp. + Babesia sp.). Eighteen goats were naturally infected with these parasites and ten healthy goats served as controls. The concentrations of nitrates and nitrites, vitamins E and C, beta-carotene and retinol were determined spectrophotometrically in the blood serum of all goats. Nitrate concentrations were higher (P0.05), whereas those of vitamin E were lower (P0.05) in infected than in control animals. These results suggest that the parasitic infections have direct effects on the concentrations of vitamin E, an important antioxidant, and on the increase of nitrate levels which may result from the pathophysiological effects of the parasitic infections.
