Tick-borne rickettsiosis are zoonoses caused by obligatory intracellular bacteria of the genus Rickettsia. Rocky Mountain spotted fever (FM), caused by the bacterium Rickettsia rickettsii, is the deadliest tick-borne disease with 489 deaths recorded between 2001-2018, many in the state of Sao Paulo. Despite the diversity of entomological fauna, there are no confirmed reports of FM in huma…
Rickettsioses are zoonoses caused by bacteria of the genus Rickettsia, endemic in nature and present in all continents of the world. Rickettsia spp. inhabit the salivary glands and ovaries of tick vectors, which are among the most common groups of arthropod hosts for these bacteria. In the Northeast region of Brazil there are few studies on this disease and in the state of Pernambuco, alm…
Argasid ticks can transmit microorganisms to their vertebrate hosts, which include humans. More specifically, some species of anthropophilic Ornithodoros transmit spirochetes of the genus Borrelia, which are the causative agents of Tick-Borne Relapsing Fever (TBRF). In South America, two species of this group were described in the first half of the 20th century. Among them, Borrelia vene…
The tick fauna of Brazil is composed of 77 species. Remarkably, 19 (25%) of these species have been discovered by science in the last 20 years, making Brazil the country with the largest number of new tick species described in the 21st century. In contrast to the vast knowledge about tick-borne diseases in the Northern hemisphere, in Brazil only two tick-borne zoonotic agents (Rickettsia …

This research project uses the One Health approach to investigate the epidemiology of Brazilian spotted fever and Q fever in indigenous and quilombola communities in the states of São Paulo and Rio de Janeiro. The study includes the collection of blood samples, ticks, vaginal swabs, feces and environmental samples for molecular and serological analysis of Rickettsia spp. and Coxiella burn…
Q fever is a zoonosis caused by the bacterium Coxiella burnetii, which has a cosmopolitan distribution and infects humans and domestic and wild mammals. In Brazil, where several human cases have already been described, including in the form of epidemic outbreaks, epidemiological studies have mostly involved domestic ruminants. Despite the growing number of human cases of Q fever diagnosed…

The expansion of Brazilian spotted fever (BSF) transmission areas in the interior of the state of São Paulo has been associated with the population expansion of capybaras, the main amplifying hosts of the etiological agent of BSF (Rickettsia rickettsii) for the tick vector Amblyomma sculptum. However, many areas with the presence of capybaras and A. sculptum remain free of R. rickettsii, …
This project is directly linked to a FAPESP Research Grant (process 2021/02976-1) within the UKRI/NERC/FAPESP Cooperation Agreement between researchers from the UK and the state of São Paulo, with a focus on researching the impacts caused by invasive species on human disease vectors, through analyses based on community and ecosystem ecology. Invasive plants can cause wide-ranging ecologic…
The expansion of areas of Brazilian spotted fever (FMB) transmission in the interior of the state of São Paulo has been associated with the expansion of the population of capybaras, the main amplifying hosts of the etiologic agent of FMB (Rickettsia rickettsii) for the tick vector Amblyomma sculptum. However, many areas with the presence of capybaras and A. sculptum remain free of R. rick…

In South America, interest in tick-borne relapsing fever begun in the early 20th century and extended almost for 50 years. After this period, research on the disease vanished, opening a gap that has prevented a current approach with contemporary tools. Recently, its etiologic agent, the spirochete Borrelia venezuelensis, was re-isolated from its vector Ornithodoros rudis, in the Maranhão …
Capybaras (Hydrochoerus hydrochaeris) are the largest rodent species globally and one of the most abundant mammals in Brazil. Capybaras populations reach high demographic rates in anthropic landscapes because of its great capability of adaptation. For this reason, they are cause of conflicts with human population, like crop damage and significant role in the natural history of tick-borne …
Rickettsia bellii is a bacterium with wide geographical distribution in the Americas, from the United States to Argentina, including Brazil. The aims of this project are the molecular characterization and phylogeographic analysis of R. bellii isolates from different species of ticks and regions of the Americas, including newly unpublished isolates that have been obtained during the presen…
