Which group of animals is frequently cited as major carriers responsible for shedding *Leptospira* into the environment?
Answer
Rodents, such as rats
Rodents, particularly rats, are frequently identified as major carriers in the reservoir ecosystem for *Leptospira*. These animals can excrete the bacteria in their urine, often without exhibiting any overt signs of illness themselves, which establishes the invisible pathway for environmental contamination. While other mammals like cattle and dogs also serve as reservoirs, rodents are consistently highlighted due to their prevalence in urban and peri-urban settings, significantly contributing to the contamination of soil and water that humans subsequently encounter.
