| description | Purpose. To study the effect of the use of indirect (express-) method for the detection of infectious pancreatic necrosis virus of trout by investigating aspartate aminotransferase and alanine aminotransferase activities in fish liver, as the most sensitive enzymes for the diagnostics of many pathological conditions of human and animal organisms associated with liver diseases.
Methodology. The determination of aspartate aminotransferase and alanine aminotransferase activities in trout liver was performed by Reitman-Frankel method. The functional status of liver was also evaluated using De Ritis coefficient (AST/ALT ratio), which serves as an integral index of the changes related to the degree of the damage of this organ.
Findings. The determination of aspartate aminotransferase and alanine aminotransferase activities in the liver of rainbow trout (Oncorhynchus mykiss) found out a considerable increase in the activity of these enzymes under the effect of the virus of infectious pancreatic necrosis. It is set that direction of aspartate aminotransferase reactions in the conditions of viral infection takes place mainly in the side of formation of keto-acids, providing the synthesis of glucose which is needed above all things for energetic supply of synthetic processes. The increase of activity of AsAT plays an important role in synchronization of energetic and nitrous exchange which is carried out at the level of mitochondrias. Increase of DeRitisa (DRr) coefficient in the conditions of our experiment characteristic for viral hepatitis and can specify on activating of synthesis of glucose which is needed for support of adequate level in the conditions of viral intoxication and determines the orientation of metabolic streams toward predominance of catabolytic reactions.
According to the results of the performed tests, the most informative was the test of the determination of alanine aminotransferase activity.
Originality. Evaluation of the effect of infectious pancreatic necrosis virus on aspartate aminotransferase and alanine aminotransferase activities in the liver of rainbow trout was performed for the first time.
Practical value. Due to the simplicity of the implementation of the analysis of alanine aminotransferase activity, this method can become effective express-method for the diagnostics of trout infectious pancreatic necrosis virus in fish farms. |
