Ginger-Derived Compounds Alleviate Oxidative Stress and Genotoxicity in Trypanosoma evansi Infection: An Integrated In Vivo and In Silico Study

Background/Objectives: Trypanosoma evansi (T. evansi) is an etiological agent of surra, and it causes significant economic losses in livestock. Rising trypanocide resistance demands alternatives that control parasitemia while mitigating oxidative and genotoxic damage. Therefore, the present study was designed to explore both the in vivo and in silico potential of Zingiber officinale (Z. officinale) as a novel phytotherapy to counter growing resistance against conventional trypanocides. Methods: Methanolic extract of Z. officinale (MZ) was orally administered at dosages of 200 mg/kg (MZ 200), 400 mg/kg (MZ 400), and 800 mg/kg (MZ 800) on a daily basis to the experimentally infected mice and compared against treated control (TC) and untreated control (UC) groups. After the infection, different parameters such as parasitemia counts, body weight changes, and the survival of infected mice were monitored for up to 7 days post-infection, while hematobiochemical parameters, oxidative stress profiles (catalase, malondialdehyde, and superoxide dismutase), and genotoxicity in brain tissues were compared at the end of the trial. Moreover, computational tools were used to predict the affinities of key bioactive compounds with twenty-one essential proteins of T. evansi. Results: The findings showed that the administration of MZ significantly (p < 0.05) reduced parasitemia and improved the survival rates in the experimentally infected mice in a dose-dependent manner. Noteworthy, significant (p < 0.05) improvements in hematological parameters and liver enzyme profiles were also recorded in MZ-treated groups. Compared to the untreated control, MZ-treated groups showed a significant amelioration in oxidative stress and genotoxicity in brain tissue in a dose-dependent fashion. The current study’s findings suggest that MZ potentially inhibits various essential proteins of T. evansi, including adenosine transporter-1, casein kinase, leucyl-tRNA synthetase, and multidrug resistance E protein. Among its constituents, 6-Isoshogaol and 6-Gingerol showed the most stable interactions in the molecular dynamics simulation. Conclusions: MZ efficiently reduced parasitemia, oxidative stress, and genotoxicity, and increased the survival rate in infected mice, suggesting it as a promising natural trypanicidal agent.
