In Vivo Antischistosomicidal and Immunomodulatory Effects of Dietary Supplementation with .

Bilharziasis is a widespread trematode parasite that poses a severe public health burden. Dandelion () has several pharmacological and traditional properties critical for treating several hepatic disorders. The present study was designed to assess the potential efficacy of root (TOR) dietary supplementation with or without praziquantel (PZQ) against liver and intestinal disorders in mice infected with . This study was conducted on five groups; G1: uninfected control, G2: untreated -infected mice, G3: infected animals treated with 250 mg/kg PZQ for three alternative days, G4: infected animals were orally administered 600 mg/kg bw TOR daily for 10 days, and G5: infected animals that received both PZQ and TOR as previously described. The current findings after different treatments indicated topographical scanning electron microscopy alterations of male adult worms and a critical reduction in worm burden, ova count, granuloma diameter, hepatic and intestinal histological abnormalities, fibrosis, immunohistochemical expression of CD3 and CD20 cells, oxidative stress, and interleukin-10, also upregulation of interferon-gamma, and antioxidant enzymes, when compared to the infected untreated mice. The best results were obtained in mice administered PZQ+TOR together because of their antioxidant properties and ability to promote the host immune response to parasitic infection.
