Background:
Fasciolosis is a parasitic disease affecting the hepatobiliary system of livestock worldwide. The control of the fluke is important to be performed in endemic regions.
Aim:
This study aims to evaluate the effect of Etlingera elatior ethanolic extract on egg and adult stadia of Fasciola gigantica.
Methods:
F. gigantica in different stages were incubated with Etlingera elatior ethanolic extract in different concentrations and time points.
Results:
The number of developed eggs with different concentrations of 1.25%, 2.5%, and 5% was significantly decreased by 36.67, 56.67%, and 56.67% on day 11 post-incubation, which showed an ovicidal effect of the herb. The developed eggs on day 14, which was represented by hatched larvae, were also decreased by 70%, 50%, and 13.33%, respectively. Significant flukicidal effects were observed in the incubation time of 80 minutes for the concentration of 20% (P= 0.007) and 640 minutes for 10% concentration (P= 0.003). Surface microscopy of adult F. gigantica showed damaged skin and spina with the erosion of the inner membrane and detached syncytium from the tegument.
Conclusion:
Overall, the results indicate that E. elatior has a promising anthelmintic property against F. gigantica in both ova and adult stages.
