PENGARUH KONSENTRASI EKSTRAK CACING TANAH (Lumbricus rubellus)TERHADAP PERTUMBUHAN BAKTERI Salmonella typhi L.Soedjoto,S.Si Prodi D3 Analis Kesehatan UM Surabaya Abstract Earthworms (Lumbricus rubellus) is one organism that is widely used as a traditional medicine. Earthworms contains very high levels of protein, enzyme, collagenase enzyme, enzyme Fibrionolycin and Prottibinolycin and seyawa class of alkaloids that contain nitrogen atoms that are bakteriostatik.Berdasarkan description above research was conducted by taking issue with the influence of earthworms and this study aims to determine the effect on growth Salmonella typhi.

While at a concentration of 20%, 10% showed a growth of Salmonella typhi. Chi-square test results showed that the mean value of p = 0.01 p <(0.05).
