Abstract

Erythrograms determined from whole blood analyses and serum analyses for aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT) and alkaline phosphatase (ALP) activities, and iron concentration, were used in infected and uninfected cattle to determine the type of anaemia and degree of hepatic damage caused by Fasciola hepatica. Blood samples from 86 infected and 30 uninfected cattle were taken at slaughter. Haematological analyses revealed decreased levels of packed cell volume (PCV), haemoglobin concentration, mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) in infected compared with uninfected cattle (P < 0.05). A decrease in the concentration of serum iron was also observed in infected cattle compared with uninfected cattle (P < 0.05). Significant increases in AST, GGT and ALP activities were observed in cattle infected with F. hepatica when compared with uninfected cattle (P < 0.05). It was concluded that the anaemia observed in cattle infected with F. hepatica is a normocytic, hypochromic anaemia and the most important aetiology of the anaemia is the chronic blood loss due to the blood-sucking activity of the adult flukes and leakage of blood from the bile duct to the intestine, which results in iron deficiency. The increased activities of serum enzymes indicated chronic hepatic and bile duct injuries associated with chronic infection with F. hepatica.
