Cutaneous leishmaniasis is frequent in equines from an endemic area in Rio de Janeiro, Brazil.
Abstract: In an endemic area of cutaneous leishmaniasis in Rio de Janeiro State where a mule had been found infected, a systematic search among equines was performed, resulting in the detection of Leishmania parasites in skin lesions of 30.8% of the animals, which included horses and mules. The eventual role of equines in the epidemiology of the human disease is being investigated.

The research study focuses on the common occurrence of cutaneous leishmaniasis, a skin disease, in horses and mules from a region in Rio de Janeiro, Brazil where this disease is endemic. The research further aims to investigate the potential role of these equines in spreading the disease to humans.
Context of the Study
- The researchers undertook this study in a region of Rio de Janeiro State, where a mule was found to be infected with cutaneous leishmaniasis. The region is known to have a high prevalence of the disease.
- Cutaneous leishmaniasis is a skin disease caused by a parasite called Leishmania. While it primarily affects animals, it can be transmitted to humans, often via insect vectors.
Purpose of the Study
- The aim of the study was to determine the prevalence of cutaneous leishmaniasis in equines, which includes horses and mules, within the endemic area.
- The study also intended to explore the potential role played by these animals in spreading the disease to humans. Understanding this aspect might be crucial for disease control strategies targeting the disease transmission cycle involving humans, animals, and insects.
Methodology and Findings
- The researchers conducted a systematic search among equines in the area. They checked for signs of infection, focusing on skin lesions that are a typical feature of this disease.
- The study found that 30.8% of the examined animals were infected with Leishmania parasites, showing that the disease is indeed frequent among equines in this region.
Implications of the Research
- The outcome of this study indicates a potential health risk for humans living in the same area where the equines are infected.
- The high prevalence of the disease among equines suggests they could play a role in the local epidemiology of the disease, acting as a reservoir for the parasite and potentially contributing to its spread to humans.
- Further investigation of this relationship is necessary as it could have significant implications for controlling the disease, both in animals and humans.
