The effect of Eimeria acervulina infection on plasma lipids and lipoproteins in young broiler chicks

Veterinary Parasitology

Abstract

In young broiler chicks inoculated with 2 x 10(6) sporulated oocysts of Eimeria acervulina per bird, total plasma lipids were significantly depressed compared with controls in the first week after inoculation. The lowest level observed was at 5 days post-inoculation (d.p.i.), at which time the chick host is known to experience malabsorption in the chick host (Ruff and Wilkins, 1980). Analysis of plasma components of infected chicks at 4 and 7 d.p.i. showed that triglycerides, total cholesterol, free fatty acids, pigments and total protein were significantly decreased compared with controls. At 7 d.p.i., reduction of total cholesterol reflected mainly reduction in high density lipoprotein (HDL) cholesterol. However, the ratio of HDL cholesterol/total plasma cholesterol was not significantly different from the control ratio. Density gradient ultracentrifugation of chick plasma separated lipoproteins into three main fractions: portomicrons plus very low density lipoproteins (PM + VLDL), low density lipoproteins (LDL) and HDL. These fractions were analyzed for lipid content. Infection with E. acervulina caused (1) significant reduction in the triglyceride and cholesterol contents of the PM + VLDL fraction at 3 and 5 d.p.i., (2) sig...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
