The earthworm perionyx excavatus exhibits a rudimentary immune system. For this study young earthworms were injected with 0.05ml of 1.0×106 cfu /ml of Staphylococcus aureus .The coelomic fluid were collected and noted the total cell counting of Perionyx excavatus before and after the pathogen infection. The data indicated a marked proliferation in total cell counts in comparison to the control worms. This trend of increasing total cell counts continued over the five days. The pathogen would be inhibited through the cellular activity of coelomic fluid.
