The black-eared opossum (Didelphis aurita) is a South American synanthropic marsupial. The presence of opossums in domestic spaces is relevant in the One-Health context since they are hosts of pathogens and ectoparasites that may affect the health of domestic animals and humans. In this study, we aim to determine the occurrence of hemoplasmas and selected tick-borne pathogens in free-ranging black-eared opossums, along with their molecular characterization, hematological and biochemical evaluation and factors associated with infection, in the municipality of Viçosa, State of Minas Gerais, southeastern Brazil. Thirty black-eared opossums were trapped between March 2021 and June 2022. Ectoparasites were collected. Hematological and biochemical analyses were performed. DNA from EDTA-blood samples were analyzed by PCR and qPCR assays. By molecular analyses, ‘Candidatus Mycoplasma haemoalbiventris’ was the most prevalent hemoparasite (73.3%), followed by Hepatozoon sp. (22.2%). Significant differences were observed in the number of platelets, and in the concentration of protein and globulins in the animals infected by ‘Ca. M. haemoalbiventris’ when compared with the negative group. This is the first report of ‘Ca. M. haemoalbiventris’ infection in D. aurita.

“…This tick species has already been found parasitizing coatis from São Paulo state [33]. All stages of A. dubitatum are primarily associated with capybaras (H. hydrochaeris), although there are reports of immature and adult stages in other mammals, such as tapirs (Tapirus terrestris) [51], crab-eating foxes (C. thous) [29], humans [23,52] as well as larvae and nymphs in black-eared opossums (Didelphis aurita) [53], white-eared opossums (Didelphis albiventris) [36,53], and Cricetidae rodents [54]. Interestingly, an interspecific association between coatis and capybaras was found in the Parque das Nações Unidas [55] located aside the PEP (where the present study was carried out).…”

“…This behavior may lead to higher prevalence and intensity of ectoparasites and parasitic infections in males than in females because they tend to disperse in a larger territory [70]. However, studies about dietary patterns and behavior of N. nasua showed different features, with adult males observed living together with females and offspring outside of the mating season in five different coati populations in Brazil (Mangabeiras Park, Minas Gerais; Tiete Ecological Park, São Paulo; Nhumirim ranch, Pantanal; Parque Estadual do Prosa, Mato Grosso do Sul; and Campeche Island, Santa Catarina) and in Foz do Iguaçu, Argentina, [1,13,[34][35][36]. It seems that both in natural [69] and anthropized areas (such as those sampled in the present study) males remain together with the group outside of the mating season.…”

“…The area has become a tourist spot for visitors from cities in the state of Mato Grosso do Sul as well as from different regions of Brazil, so there is a high daily circulation of people (approximately 2000 visitors attend the PEP during the week, and on weekends, it can exceed 6000 users) [34]. It is an important refuge for wildlife, where many species of mammals can be found, such as ring-tailed coatis (N. nasua) [34,35], anteaters (Myrmecophaga tridactyla and Tamandua tetradactyla) [34], capybaras (Hydrochoerus hydrochaeris) [34] opossums (Didelphis albiventris) [36][37][38], bats (e.g., Artibeus sp. and Myotis nigricans [39], birds (e.g., Cuculidae and Psittacidae) and reptiles (Tupinambis spp.)…”

Understanding the diversity and ecology of ectoparasites in wild animals is essential for surveillance of vector-borne diseases. Coatis (Nasua nasua) easily adapt to anthropized areas, favoring close contact with domestic animals and humans, with the possibility of exchange of ectoparasites and pathogens. The present study aimed to identify the diversity of ticks parasitizing coatis from forest urban areas of midwestern Brazil, to evaluate the seasonal dynamics of ticks during the seasons of the year, and to assess the correlation between tick species and gender and age of the sampled coatis. For this purpose, 103 coatis were captured in two Conservation areas, both located in Campo Grande city, Mato Grosso do Sul state, Midwestern Brazil. The animals’ entire body was inspected for the presence of ectoparasites, and ticks were removed for taxonomic identification. In total, 168 captures were performed in both areas during the observational study considering the first capture and recaptures. In total, 2242 ticks were collected: 838 Amblyomma larvae, 1241 A. sculptum nymphs, and 150 A. dubitatum nymphs. Thirteen adult ticks were identified as three males and five females of A. sculptum and two males and three females of A. ovale. While a quantity of Amblyomma larvae was observed in the first months of the year (January, April and May), Amblyomma nymphs showed a higher quantity during the months of July, August, October and November. No statistical difference was observed when comparing mean intensity and prevalence of Amblyomma larvae, nymphs of A. sculptum and A. dubitatum between the two sampled areas, males vs. females and immature vs. mature animals. In conclusion, three tick species were identified parasitizing coatis from forested urban fragments in midwestern Brazil, namely A. dubitatum nymphs, A. sculptum adults and nymphs, and A. ovale adults. Coatis from anthropized areas seem to present tick species diversity lower than those from natural areas. The lack of statistical difference regarding mean intensity and prevalence of Amblyomma larvae and nymphs between males vs. females and immature vs. mature animals might have reflected the gregarious behavior of coatis, since adult males live together with females and offspring outside and inside the mating season, forming large groups of individuals.
