Investigation of Antibacterial Properties of Mucus and Coelomic Fluid Obtained from Eisenia Fetida
Abstract
In several researches
it was found that earthworms are protected from the infective effects of many
pathogen microorganisms, with which they live together, by their strong immune
systems and secreted fluids; in addition, vermicompost, their coelomic fluid and
mucus are effective against certain bacteria. In this study, Disk Diffusion,
Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration
(MBC) tests were applied to determine the activities of the extracts obtained
from coelom-mucus fluids of Eisenia fetida type earthworm against seven
pathogenic bacteria causing diseases in plants.
At the end of the study, zone diameters of the coelom-mucus fluids
obtained from earthworms were measured to be between 8-54 mm, whereas their MIC
and MBC values
varied between 0.06-0.5 mg/mL and 0.25-2 mg/mL, respectively. The
findings showed that antibacterial activity of coelom-mucus fluids obtained from E. fetida type earthworms on
plant pathogens is remarkable. This study is expected to enlighten
future studies investigating antimicrobial effects, structure and activity
mechanisms of the isolates and extracts obtained from E. fetida and other types of earthworm.
