“…As for the marmosets, the marsupial samples collected in the present study all tested negative. Gonçalves et al (2020b) challenged the idea that Brazilian marsupials are natural hosts of Bartonella , given that, in both their research and previous studies ( de Sousa et al, 2018 ; Fontalvo et al, 2017 ), the DNA of Bartonella was not detected in any of the marsupial specimens or their vectors analyzed. Neotropical marsupials are a very diverse group, with both animals specialized for more preserved environments, as well as more generalist species with an ample distribution, such as the species of the genus Didelphis ( Cáceres et al, 2012 ), which are relatively abundant animal, and are common in residential and rural areas.…”

“…Eleven species of bat have also tested positive for Bartonella by PCR ( André et al, 2019 ; Ferreira et al, 2018 ; Ikeda et al, 2017 ), including animals in protected areas in the Amazon and Cerrado biomes, and the Atlantic Forest region of the states of Rio de Janeiro (Pedra Branca State Park), Bahia (APA do Pratigi), and Santa Catarina (Serra do Tabuleiro State Park). Up to now, however, no evidence of infection by Bartonella has been found in Brazilian non-human primates ( Bonato et al, 2015 ; Melo et al, 2017 ) or marsupials ( de Sousa et al, 2018 ; Gonçalves et al, 2020b ).…”

The Bartonella species are zoonotic agents that infect mammals and are transmitted by arthropod vectors. Approximately 18 distinct genotypes cause diseases in humans, and may be spread by both domestic and wild animals. In Brazil, Bartonella genotypes have been identified in several species of wild mammals, and in the present study, we analyzed samples from non-human primates (marmosets), marsupials, rodents, and bats, and compared them with the genotypes described in mammals from Brazil, to examine the distribution of Bartonella genotypes in two impacted areas of Rio de Janeiro state, in southeastern Brazil. We used polymerase chain reaction (PCR) methods to detect the Bartonella DNA using partial sequences of the gltA, ftsZ , and groEL genes. We generated Bayesian inference and maximum likelihood trees to characterize the positive PCR samples and infer the phylogenetic relationships of the genotypes. A total of 276 animals were captured, including 110 bats, 91 rodents, 38 marsupials, and 37 marmosets. The DNA of Bartonella was amplified from tissue samples collected from 12 (4.34%) of the animals, including eight rodents – Akodon cursor (5/44) and Nectomys squamipes (3/27) – and four bats, Artibeus lituratus (3/58) and Carollia perspicillata (1/15). We identified Bartonella genotypes closely related to those described in previous studies, as well as new genotypes in both the rodent and the bat samples. Considering the high diversity of the Bartonella genotypes and hosts identified in the present study, further research is needed to better understand the relationships between the different Bartonella genotypes and their vectors and host species. The presence of Bartonella in the wild rodents and bats from the study area indicates that the local human populations may be at risk of infection by Bartonella due to the spillover of these strains from the wild environment to domestic and peri-domestic environments.

“…A recent study demonstrated that rodent populations that live far from the coast showed a lower infection rate for Bartonella spp. than those near coastline (Gonçalves et al, 2020). In that study, capybaras from Campo Grande municipality, Mato Grosso do Sul State, midwestern Brazil, were infested with ticks (Amblyomma sp.…”

“…Despite many rodents have been identified as reservoirs for Bartonella spp. (Gutiérrez et al, 2015), the role of capybaras (Hydrochoerus hydrochaeris), the biggest rodent in the world, have been scarcely investigated (Gonçalves et al, 2020). This mammal species inhabits wetlands from South America in conserved environments to urban parks, where they coexist with humans (Queirogas, Del Claro, Nascimento, & Szabó, 2012).…”

“…Similarly, ticks (A. dubitatum, Amblyomma sculptum, and Amblyomma sp. larvae) parasitizing Mus musculus, Rattus rattus, capybaras, and opossums (Didelphis albiventris), also tested negative for Bartonella in Midwestern Brazil (Gonçalves et al, 2020). It is a notorious evolutionary adaptation that some bacterial agents are developed as tickborne pathogens, like Ehrlichia, Anaplasma, and Rickettsia (Mccoy, Léger, & Dietrich, 2013).…”

Bartonella is an emerging group of facultative intracellular bacteria causing circulatory and systemic disorders. Hosts for Bartonella are mostly mammals, specifically rodents, having a growing number of Bartonella species related to their infection. Capybaras (Hydrochoerus hydrochaeris) are abundant native rodents of Brazil, commonly found in urban parks. In the present study, we aimed to perform molecular screening of capybaras for Bartonella spp. Blood samples were collected from 17 free-ranging animals captured in Paraná State, Southern Brazil. None of the collected samples tested positive for the Bartonella-nuoG gene by quantitative polymerase chain reaction (qPCR), although all of them successfully amplified the mammal endogenous glyceraldehyde-3-phosphate dehydrogenase (gapdh) gene. Additionally, all animals were infested exclusively by Amblyomma dubitatum ticks at the time of sampling. This study was part of an active surveillance program, which is critical for monitoring animal health status, particularly in capybaras.
