Abstract
Earthworm increases the soil fertility and is often referred to
as a farmer’s friend. The bacterial pathogen Pseudomonas (P)
aeruginosa associated with the earthworm, penetrate into the body,
cause diseases to the host and leads to the opportunistic infection.
Eisenia (E) foetida collected from the local soil and P. aeruginosa spp.
were isolated. The bacterial strain was confirmed through
morphological and biochemical tests. In order to control the
pathogenicity of P. aeruginosa, we used chloroform and
isoamylalcohol extracts of medicinal plant including Cinnnamomum
zylanicum, Cuminum cyminum, Syzygium aromaticum, Curcuma long
Linn, Trachyspermum ammi as well as the n-Hexane, chloroform,
ethanol, methanol and ethyl acetate extracts of Momordica charantia
were investigated. On the other hand antibiotic sensitivity showed that
isolated P. aeruginosa was highly sensitive to streptomycin,
gentamycin and ciproflaxin. It was concluded that the extracts of these
medicinal plants have considerable effect on the bacterial pathogens.
Isolation and purification of different phytochemicals may further yield
significant antibacterial agents.
