title: Plasma high density lipoprotein in anemic cattle infected with Theileria sergenti.
abstract: Changes in plasma concentration of lipid composition were analysed in cattle with anemia due to Theileria sergenti infection. Plasma levels of phospholipids, cholesterol, free cholesterol, high density lipoprotein cholesterol, and vitamin E decreased to 40-67% of the pre-infection levels, corresponding to the decrease of PCV due to the infection. However, no definite changes were detected in plasma level of triglyceride. By gradient centrifugation, it was confirmed that lipid components, other than triglyceride, occur in high density lipoprotein (HDL) and these decreases lowered the HDL value. There was no correlation between this phenomenon and liver function. As similar changes in lipid composition were also observed in phlebotomized calves, it was considered that this phenomenon might partially depend on the acceleration of erythropoiesis as a reaction to anemia caused by T. sergenti infection.
