leptospira illterrogalls are shed into the environment by rats and rodents can cause leptospirosis disease among humans. This study investigated the survival of pathogenic leptospira in different types of soils. In this study, samples of alluvial, arenaceous, peat and red-yellow podzolic soils at different water concentration (20%, 30% and 40%) were inoculated with 108 CFU/ml of leptospira interrogans. The samples were withdrawn at day 3,6, 9 and weekly at day 16 until day 30. This study shows significant difference (p<0.05) in the survival of leptospira illterrogans in alluvial, arenaceous, peat and red-yellow podzolic soils at different water concentration (20%, 30% and 40%). leptospira illterrogans have the highest survival in alluvial soil at 40% water concentration. Result of this study proved that the types of soil and water concentration can affect the survival of leptospira interrogans in environmental soil. Therefore, the result from this study can be used as the background data for future studies related to the survival on pathogenic leptospira.
