Molecular detection of pathogenic leptospiral protein encoding gene (lipL32) in environmental aquatic biofilms

Abstract

Little is known regarding the mechanisms by which pathogenic leptospires persist in aqueous environment, outside the mammalian host. In this view this is the first report of the distribution of Leptospira in environmental biofilm such as sewers and paddy leaf surfaces. This ability of pathogenic Leptospira to survive in aquatic ecosystems especially in biofilms could be one of the main factors which facilitate its survival in the environment, and thus disease transmission among the risk groups, such as sewage and agriculture worker. This study will encourage researchers in the field to consider biofilm as an important factor, when detecting leptospires in environment.
