Hypothesis
The study aims to compare the density and diversity of leptospires in urban versus rural environmental water sources in the Peruvian Amazon.
Conclusion
The study found that urban water sources had significantly higher densities of leptospires compared to rural sources, and identified a new branch of the leptospiral phylogenetic tree.
Supporting Evidence
- Leptospirosis is a widespread public health problem in tropical regions.
- High densities of leptospires were found in urban water sources, particularly in areas with open sewers.
- A new branch of the leptospiral phylogenetic tree was discovered in the study.
Takeaway
Scientists looked at water in cities and farms in the Amazon to see how many germs that can make people sick were there, and they found a lot more in the city water.
Methodology
Water samples were tested using quantitative polymerase chain reaction to identify leptospiral pathogens.
Limitations
The relevance of the new leptospire(s) to human disease is unknown.
