Cassia alata: Helminth and Bacteria Fighter.

Introduction: The concurrent presence of helminthiasis and bacterial diseases imposes a dual burden, worsening the challenges associated with each condition independently. This cohabitation intensifies the economic impact, creating a compounding effect on public health and economic well-being.

Method: Phytochemical analysis of Cassia alata Extract (CAE) using infrared spectroscopy has revealed the presence of various functional groups. In addition, GC mass analysis has confirmed the presence of 26 active compounds. An assessment of the anthelmintic activity of CAE against mature earthworms has demonstrated comparable efficacy to the conventional anthelmintic, albendazole. The optimal dosage of 500 mg/ml has induced a rapid onset of paralysis (2.7 ± 0.5 min) and death (20.1 ± 1.7 min), outperforming albendazole (20 mg/mL) in terms of faster paralysis and death times (21.8 ± 1.1 and 30.14 ± 3.2 min, respectively). Structural modifications induced by CAE have been observed through light microscopy and Scanning Electron Microscopy (SEM). Control worms have exhibited normal body architecture, while CAE-treated worms have displayed size reduction, uniform body wall shrinkage, and increased cuticular thickness. Similar alterations have been observed in albendazole-treated worms.

Results: The antibacterial activity of CAE has been evaluated through a broth dilution assay, which has revealed a dose-response effect. At 6.25 mg/ml, CAE has exhibited 100% inhibitory action against both Gram-positive and Gram-negative bacteria. Significant differences in bacterial viability have been noted at lower concentrations, with no significant variation at 0.3906 mg/ml of CAE.

Conclusion: The findings have highlighted the multifaceted bioactivity of CAE, showcasing its potential as an anthelmintic agent and antimicrobial agent against a spectrum of bacterial strains. The observed structural alterations in treated worms have provided insights into the potential mechanisms underlying the anthelmintic effects.
