Article Synopsis
- Habitat fragmentation is a major threat to primate survival, and this study focused on understanding pathogens in the free-living primates of Rio Grande do Sul, Brazil, particularly looking for antibodies against Neospora caninum, Toxoplasma gondii, and Sarcocystis spp.
- Researchers analyzed serum samples from 105 monkeys, including black howler monkeys and capuchin monkeys, using specific tests to detect antibodies and explored how various landscape features influenced exposure to these pathogens.
- Findings showed that 13.3% of samples were positive for N. caninum, 4.8% for T. gondii, and 5.7% for Sarcocystis
Leptospirosis is an endemic disease in the State of Rio Grande do Sul, Brazil, and presents a broad diversity of exposure routes, reservoirs, etiological agents, and clinical features. The main objective of this work is to identify transmission areas and possible ecological components of leptospirosis transmission. This was accomplished through the aggregation of epidemiological data into spatial units that represent the State's socio-environmental diversity.
