Abstract
It is known that highly reactive oxygene species produced during normal cellular metabolism represent a powerful effector mechanism against parasites. Superoxide dismutase (SOD) and glutathione peroxidase (GPx) belong to the main defense anti-oxidants that prevent the formation of new free radical species. The aim of this study was to assess the activities of SOD and GPx in cattle tissues infected with Taenia saginata. We observed a statistically significant increase in the SOD and GPx activities (p=0.00003, 0.00008, respectively, Student’s t-test) in skeletal muscles infected with T. saginata in spectrophotometric analysis. With the use of western blot technique, SOD synthesis stimulation has appeared in the host tissues containing cysticerci in contrast with the control samples. There was no statistically significant increase in the GPx band intensity observed in the studied samples in comparison to controls (Gene Tools Version 4.01 program). These results support the significance of anti-oxidant processes in host defense mechanism during parasitic infections.
