Effect on biochemical parameters in naturally infected calves with giardiasis after treatment with albendazole in van province, Turkey

The aim of this study was to investigate the changes in the blood serum levels of some biochemical parameters, lipid-soluble vitamins and trace elements in the calves naturally infected with Giardia spp. in Van region, before and after treatment with orally 20 mg/kg⁻¹ albendazole three successive days. Serum samples were analyzed for biochemical parameters and some vitamins. In the infected animals, concentrations of creatinine, amylase levels were lower (p< 0.05). Glucose, urea, total protein, AST, ALT, sodium, potassium, retinol and α-tocopherol levels were seen significantly higher in the after treatment group (p< 0.05). There was no statistically significant difference in the concentration of total bilirubin, chloride and vitamin D₃ between groups. All the animals were not encountered cysts or trophozoites of Giardia at the end of the treatment. The results of this study would suggest albendazole to be 100% effective against giardiasis in all of the calves in Van region.
