Indicative parameters for liver fascioliasis at pre-clinical and clinical phases in cows from Al-Diwaniyah City, Iraq
Iraqi Journal of Veterinary Sciences,
The current work emphasized on understanding the liver functions while having a pre-clinical or clinical fascioliasis for the accurate detection of the disease phase from cows in Al-Diwaniyah City, Al-Qadisiyah Province, Iraq. The experimental design included the use of 30 cows in a farm divided into 10 clinically healthy cows , 10 acutely infested cows with no obvious clinical signs (pre-clinical group), and 10 chronically infested cows with observed clinical signs (clinical group), such as yellowish discoloration of the mucus membranes. Blood samples were collected from each cow for performing the following tests: Alkaline phosphatase , alanine transaminase , aspartate transaminase (AST), gamma-glutamyl transferase , pyruvate, lactate, and cholesterol. The results showed that all the enzymes from the pre-clinical group were significantly (p˂0.05) higher in their serum levels compared with those from the control group to elevate to significantly (p˂0.05) higher levels in the clinical group in comparisons with those from the control and pre-clinical groups, excluding the ALT that revealed no significant (p˃0.05) difference between the pre- and clinical groups. For the cholesterol, significant (p˂0.05) increases were seen in the pre-clinical group compared to those from the control group with no significant (p˃0.05) difference between the pre- and clinical groups. At the levels of serum pyruvate and lactate, no significant (p˃0.05) differences were recorded between all study group. The present study reveals that the fascioliasis, dependent on the infestation phase, can progressively change the serum levels of the above mentioned parameters.
