Abstract: Spotted Fever Rickettsioses (SFR) are diseases caused by bacteria of the genus Rickettsia, and are transmitted mainly by ticks. Its eco-epidemiological scenarios vary spatially, and may also vary over time due to environmental changes. It is the main disease transmitted by ticks to humans in Brazil, with the state of Paraná (PR) having the sixth highest number of notified incidences in the country. However, information is lacking regarding the SFR disease cycles at likely infection sites within PR. During case… Show more

“…Although two R. sanguineus from dogs sampled were found infected by Rickettsia spp., the participation of dogs in the BSF cycle and the risk of human infection must be considered (Moerbeck et al., 2016; Szabó, Pinter, et al., 2013). Rickettsia parkeri strain Atlantic rainforest infection was confirmed in four A. ovale specimens, corroborating to previous report of A. ovale infection in a dog from nearby preserved area of Atlantic rainforest biome in Paraná State seashore (Durães et al., 2021), and other Brazilian states within the Atlantic rainforest (Acosta et al., 2018; Barbieri et al., 2014; de Oliveira et al., 2019; Faccini‐Martínez et al., 2020). Domestic dogs with access to areas of Brazilian Atlantic Forest have frequently demonstrated parasitism of A. ovale , which may increase the risk of infection by Rickettsia spp.…”

“…Capybaras occur in several biomes in preserved and anthropized areas including urban areas of Minas Gerais as observed in Juiz de Fora and Belo Horizonte municipalities. In the present study, contact with capybaras did not appear as a relevant factor in the suspicion of FM, both in mild cases and in cases that progressed to death, as was also noted in RJ and Paraná (29,30). However, direct contact with capybaras is not necessary for human tick bite to occur.…”

“…However, the results obtained have shown that the control of spotted fever is highly complex because of the many factors involved, requiring strategic control [ 39 ]. Therefore, actions are needed to enable population control of capybaras, environmental control of the evolutionary forms of A. sculptum , isolation of the most critical areas of parks to minimize human contact with ticks and, last but not least, the search for tools that enable tick control at the time they are parasitizing capybaras.…”
