Holothuria polii Extract as a Potential Anticoccidial Agent: Evidence of Its MUC2 Regulatory Impact in Murine Jejunum.

Simple Summary: Natural products offer significant potential in the fight against parasitic diseases. Coccidiosis is a disease caused by the Eimeria genus of parasites that infect many animals all over the world. The development of resistance to anticoccidial medications has refocused attention on finding new compounds for alternative therapeutic approaches. The purpose of this study was to determine the efficacy of Holothuria polii extract (HpE) in treating eimeriosis in mice. The results indicated that animals treated with 200 mg/kg of HpE showed a significant decrease in oocyst count and higher expression of the MUC2 gene. In conclusion, HpE functions as an anticoccidial substance. Eimeria is a parasite that causes coccidiosis in a variety of animals, leading to nutritional imbalances, issues with food digestion and absorption, low weight, and intestinal inflammation of varying degrees in its hosts. Anticoccidial medication resistance has become a significant obstacle to disease control efforts, leading to a renewed focus on discovering novel chemicals for alternative therapeutic approaches. The purpose of this study was to determine the efficacy of Holothuria polii extract (HpE) in treating eimeriosis in mice. Five groups of mice were studied, with E. papillata sporulated oocysts (1 × 10³) used to infect three groups experimentally. The first group was treated with 200 mg/kg of HpE, the second group with Amprolium (120 mg/kg), and the third group was left untreated as a control. The fourth and fifth groups were uninfected, with one of them treated with 200 mg/kg of HpE and the other used as a negative control. The results revealed that HpE has 10 phytochemical compounds according to GC-MS analysis. Treatment with HpE resulted in a substantial decrease in oocyst output in feces. Also, the parasitic stages showed morphometric alterations, with reductions in the measurements compared with the infected, untreated mice. Moreover, expression of the mucin gene (MUC2) was higher in treated mice compared to infected ones, with significant increases in goblet cell numbers, which provided additional evidence for the activity of HpE as an anticoccidial product. In conclusion, there are a wide variety of natural products and many have been employed in folk medicine for treating a range of parasitic diseases. [ABSTRACT FROM AUTHOR]
