Changes in selected serum components were investigated to elucidate metabolic profile in cattle naturally infected with T. annulata. Statistically significant increases were observed in the mean serum activity of aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transferase, bilirubin, creatinine, urea, and creatinine kinase, and statistically significant decreases were seen in the mean serum contents of glucose, total protein, albumin, triglycerides, cholesterol, calcium, and phosphorus, along with a non-significant decrease in iron level in infected animals when compared with controls (uninfected). The study has shown that T. annulata infection in cattle is associated with profound biochemical changes.
