Survey of Trypanosoma and Leishmania in wild and domestic animals in an Atlantic rainforest fragment and surroundings in the state of Espírito Santo, Brazil.
Abstract: Trypanosoma and Leishmania infections affect wild and domestic animals and human populations. The growing process of deforestation and urbanization of Atlantic Rainforest areas has given rise to introduction of humans and domestic animals to the sylvatic cycles of Trypanosoma and Leishmania species. Serological, parasitological, and molecular surveys among wild and domestic animals in the Corrego do Veado Biological Reserve, which is an Atlantic Rainforest fragment in the state of Espírito Santo, southeastern Brazil, were evaluated. In total, 154 wild animals of 25 species and 67 domestic animals (47 dogs and 20 horses) were sampled. All the domestic animals were serologically negative for anti-Leishmania infantum chagasi antibodies and negative in parasitological approaches. Only the Order Chiroptera presented positive blood cultures and cryopreserved isolates. The phylogenetic trees based on SSU rDNA and gGAPDH genes confirmed the occurrence of Trypanosoma dionisii and provided the first record of Trypanosoma cruzi marinkellei in southeastern Brazil. The studies conducted in Atlantic Rainforest remaining trees provide the knowledge of parasite diversity or detect parasites that can accelerate the loss of hosts diversity.

The research article discusses a study conducted to identify and analyse Trypanosoma and Leishmania infections in both wild and domestic animals, within the Corrego do Veado Biological Reserve in southeastern Brazil.
Research Background
- Trypanosoma and Leishmania are parasitic infections that affect various animal species, including humans.
- The increasing reduction of the Atlantic Rainforest due to deforestation and urbanisation has led to greater human and domestic animal interaction with these parasites.
- The aim of this research was to conduct a parasitological and molecular investigation of these infections among animals within a fragment of the Atlantic Rainforest.
Methodology
- The study was conducted in the Corrego do Veado Biological Reserve in Espírito Santo, southeastern Brazil.
- 154 wild animals from 25 species and 67 domestic animals (47 dogs and 20 horses) were sampled for the research.
- The blood samples of these animals were checked for Leishmania infantum chagasi antibodies and other parasitic indicators.
Findings
- All the domestic animals tested negative for anti-Leishmania infantum chagasi antibodies. They were also negative on other parasitological checks.
- Among wild animals, only those belonging to the Order Chiroptera showed positive blood cultures and cryopreserved isolates.
- The researchers confirmed the presence of Trypanosoma dionisii.
- Interestingly, the team recorded the first known case of Trypanosoma cruzi marinkellei in southeastern Brazil, based on phylogenetic analysis of SSU rDNA and gGAPDH genes.
Implication
- The research contributes to our understanding of parasitic diversity in remaining Atlantic Rainforest fragments and could help in the detection of parasites that accelerate the loss of host diversity.
