Effect of parasitic infection on levels of some biochemical parameters in serum of Cattle in Mosul city

Abstract

The objective of this study was to diagnose internal parasites in cattle, and examine the changes in total proteins and lipids associated to the parasitic infection. with total of 85 cow was included in this study. Fecal samples were examined by direct smear, flotation, and sedimentation methods to diagnose internal parasites and Blood samples were collected to harvest serum for estimation of total proteins (TP), total Cholesterol (TCHO), and triglycerides (TG) levels using commercial kits. High density lipoproteins (HDL), very low density lipoproteins (VLDL), and low density lipoproteins (LDL) were calculated using specific equations.The Results indicated that the overall prevalence of parasitic infection in cattle was 50.48% .with different trematodes, cestodes, nematodes eggs and larvae, protozoa oocysts were diagnosed, including single and mixed infection. In infected cattle, there was significant decrease in cholesterol, HDL, and LDL; no significant decrease in total proteins; and no significant differences in triglycerides and VLDL between infected and non-infected cattle. In conclusion, different internal parasites can infect cattle, and the parasitic infection can change the metabolism leading to changes in proteins and lipids metabolism.
