Partial characterization of superoxide dismutase activity in the Barber pole worm-Haemonchus contortus infecting Capra hircus and abomasal tissue extracts
Objective: To determine the activity of superoxide dismutase (SOD) in the male and female haematophagous caprine worms, Haemonchus contortus infecting Capra hircus, and their E/S products and also to analyse the effect of Haemonchus infection on the level of host SOD. Methods: The SOD activity was a...
