Susceptibility of two strains of mice to the infection with Schistosoma mansoni: Parasitological and biochemical studies

Abstract

In this article, two strains of mice BALB/C and C57 were infected with Egyptian strain of Schistosoma mansoni. BALB/C mice appeared to harbor fewer parasites than did C57 mice. The hepatic and intestinal tissues of C57 mice were loaded with more eggs than that of BALB/C mice. Regardless the strain of mice, the number of eggs per gram of liver tissues was higher than in the intestinal tissues. Some biochemical parameters were measured in the liver of infected and non-infected mice; a significant decrease in the activities of alkaline phosphatase, catalase, glutathione-s-transferase, glutathione, and total lipids of infected mice compared to their matched control were observed. However, there was a significant increase in malondialdehyde level of infected mice compared to their matched group. Detailed discussion on the parasitological and biochemical differences between the two strains was presented. © 2008 Springer-Verlag.
