Effects of Eimeria labbeana and E. stiedai infection on the activity of some enzymes in the serum and liver of their hosts

Abstract

Glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), alkaline phosphatase and acid phosphatase activities were measured in the serum and liver of both normal and Eimeria-infected palm doves and rabbits. No significant increase in GOT activity was noticed in the serum of infected male or female palm doves. In contrast, GOT activity decreased insignificantly in the liver of both sexes of infected birds. On the other hand inoculated rabbits showed a significant increase in the serum GOT activity of both sexes. In the liver, however, a non-significant increase in GOT activity was obtained in males and a non-significant decrease, in females subsequent to infection. Serum GPT activity showed a highly significant increase in infected male doves and a significant increase in females; liver GPT activity decreased non-significantly in both sexes. Infected rabbits showed a non-significant increase in GPT activity in the serum and liver of both males and females. The activity of alkaline phosphatase in infected male palm doves was found to increase significantly in serum and highly significantly in liver. In contrast, enzyme activity in both the serum and the liver of female doves was found to decrease insignificantly after infection. In infected male and female rabbits, the activity of serum alkaline phosphatase increased non-significantly, whereas liver alkaline phosphatase activity decreased significantly in male animals and non-significantly in female rabbits. Acid phosphatase activity showed a highly significant decrease in both the serum and the liver of infected male palm doves; on the other hand, it increased non-significantly in both the serum and the liver of infected females.(ABSTRACT TRUNCATED AT 250 WORDS)
