All positive sites in Puerto Rico illustrating the relationship between <i>lipL32</i> genotypes found in soil and water.

In total, 15 sites were positive for pathogenic Leptospira DNA; eight sites wherein only soil was positive, two sites wherein only water was positive, and five sites wherein both soil and water were positive (highlighted in gray). At four of the latter sites, the clades present in water were a subset of the clades identified in soil (bolded text), suggesting that soil reservoirs may lead to the contamination of water.
