Prevalence of bacteria of division TM7 in human subgingival plaque and their association with disease.

abstract：:There have been few reports on the epidemiological analysis of environmental Leptospira isolates. This is probably because the isolation of leptospires from the environment was usually unsuccessful due to the overgrowth of contaminants and the slow growth of Leptospira. In this study, we collected a total of 88 sample...
