The aim of the present study was to determine serum concentrations of the products of nitric oxide oxidation (nitrate and nitrite) and some vitamins (retinol acetate, alpha- and delta-tocopherol, and vitamin D 3) in sheep naturally infected with Babesia ovis. The investigation included 30 infected and 10 control sheep. Serum a- tocopherol levels were significantly lower (P < 0.05), and nitrate and nitrite concentrations were significantly higher (P < 0.05) in infected animals than in controls. It is thought that the elevated nitrate and nitrite levels of the sheep infected with babesiosis were due to the result of damage caused by Babesia. On the other hand, a significant decrease was observed in a- tocopherol levels in sheep with babesiosis because of damage and pathophysiological changes to erythrocytes.
Serum Concentration of Copper, Zinc, Iron, and Cobalt and the Copper/Zinc Ratio in Horses With Equine Herpesvirus-1
(Humana Press inc, 2007) Yoeruek, Ibrahim; Deger, Yeter; Mert, Handan; Mert, Nihat; Ataseven, Veysel
The serum concentrations of copper, zinc, iron, and cobalt and copper/zinc ratio were investigated in horses infected with equine herpesvirus-1 (EHV-1). Nine horses were naturally infected with the virus and nine healthy horses served as controls. The concentrations of copper, zinc, iron, and cobalt were determined spectrophotometrically in the blood serum of all horses. The results were (expressed in micrograms per deciliters) copper 2.80 +/- 0.34 vs 1.12 +/- 0.44, zinc 3.05 +/- 0.18 vs 0.83 +/- 0.06, iron 2.76 +/- 0.17 vs 3.71 +/- 0.69, cobalt 0.19 +/- 0.37 vs 0.2 +/- 0.45, and copper/zinc ratio 0.72 +/- 0.38 vs 1.41 +/- 0.36 for control vs infected group, respectively. In conclusion, copper and zinc concentrations of the infected group were lower than the control group (p < 0.001), whereas iron concentration and the copper/zinc ratio of the infected group were higher than the control group (p < 0.05 and p < 0.001). The cobalt concentration was not found to be statistically different between two groups. It might be emphasized that copper/zinc ratio was significantly affected by the EHV-1 infection, so it could be taken into consideration during the course of infection.
