Correlation of landscape features present on individual farms in Puerto Rico to Leptospira prevalence among host species collected from five farms in Puerto Rico during summers 2014 and 2015.

Host species included Rattus rattus, R. norvegicus, Mus musculus, and Herpestes auropunctatus. Distances between host species and selected landscape features were calculated from GPS coordinates using the haversine equation. Welch’s t-tests were used to determine if the average distance of positive samples to the landscape features were closer than the average distance of negative samples using an aloha value of 0.05. Significant results are denoted in bold.
