The filarial parasite of Bos indicus, Setaria digitata is reported to have many unique characteristics such as cyanide insensitivity and mitochondrial hydrogen peroxide production. The latter is more sensitive to the alternative oxidase inhibitor salicylhydroxamic acid (SHAM). Studies on the
Spermine and spermidine were found to be the principal polyamines in the bovine filarial parasite Setaria cervi, whereas putrescine was observed in very low amounts. Studies conducted on the enzymes of polyamine biosynthesis revealed low activity for S-adenosyl-methionine decarboxylase, questionable
Antioxidant enzymes are the parasite's premier resource to defend themselves against reactive oxygen species generated by macrophages, neutrophils and eosinophils of the host. These enzymes may be particularly important for parasites involved in chronic infections, such as parasitic helminths.
BACKGROUND
Lymphatic filariasis is a major neglected tropical disease. Diospyros perigrena Gurke (Ebenaceae) was selected for antifilarial chemotherapy because of unavailability of proper medicine. In India, different parts of this plant were used for the treatment of diabetes, diarrhea, dysentery,
The main problem regarding the chemotherapy of filariasis is that no safe and effective drug is available yet to combat the adult human filarial worms. Setaria cervi, the causal organism of setariasis and lumbar paralysis in cattle, is routinely employed as a model organism for conducting
beta-D-galactosidase (beta-D-galactoside galactohydrolase, E.C. 3.2.1.23) activity was localised in the digestive tract of Setaria digitata. The enzyme extract shows maximum activity in the pH range between 3.5 and 5.0 and at 45 degrees C. The enzyme shows the Km value of 3.636 mM for the substrate
