Benzidine oxidative activation may proceed by peroxidase-catalyzed one-electron oxidation via free radical intermediates, or by N-acetylation followed by monooxygenase-catalyzed N-hydroxylation. The peroxidase route has been examined by using horseradish peroxidase or prostaglandin H synthase in vitro. In the presence of

Strongyloidiasis is a persistent human parasitic infection caused by the intestinal nematode, Strongyloides stercoralis. The parasite has a world-wide distribution, particularly in tropical and subtropical regions with poor sanitary conditions. Since individuals with strongyloidiasis are typically asymptomatic, the infection can
