Abstract | Leptospirosis, a zoonosis caused by pathogenic Leptospira, primarily a ects tropical,
developing regions, especially communities without adequate sanitation. Outbreaks of leptospirosis
have been linked with the presence of pathogenic Leptospira in water. In this study, we measured the
physicochemical characteristics (temperature, pH, salinity, turbidity, electrical conductivity, and total
dissolved solids (TDS)) of surface waters from an urban slum in Salvador, Brazil, and analyzed
their associations with the presence and concentration of pathogenic Leptospira reported previously.
We built logistic and linear regression models to determine the strength of association between
physicochemical parameters and the presence and concentration of Leptospira. We found that salinity,
TDS, pH, and type of water were strongly associated with the presence of Leptospira. In contrast,
onlypHwas associated with the concentration of the pathogen in water. The study of physico-chemical
markers can contribute to a better understanding of the occurrence of Leptospira in water and to the
identification of sources of risk in urban slum environments. | pt_BR |
