摘要：Earthworms are soil invertebrates which play a major role in recycling organic matter in soils. The unique microenvironment of the earthworm gut impacts on the catabolic activities of ingested soil microorganisms. The ingested microbial populations play an important role in earthworm nutrition by helping in the breakdown of organic matter. A study was carried out to find out the distribution of microorganisms in the gut of earthworm, Eudrilus eugeniae. The vermibeds were prepared with cow dung and pre-decomposed banyan leaf litter. The population of bacteria, fungi and actinomycetes were determined in the gut regions (foregut, midgut and hindgut) of earthworm E. eugeniae. The predominant microorganisms found in the foregut, midgut and hindgut were bacteria, actinomycetes and fungi respectively. It was observed that there are variations in the population of microorganisms in the foregut, midgut and hindgut. This report shows the distribution of various microorganisms in the gut regions and how it favors the animal to have a healthy life in the environment.
