“…In nature, TBPs have been reported in different species ranging from small to large animals worldwide (Table 1) as listed for the US [70], Canada [72], South America [65,74], Europe [28,63,68,69,75], Australia [76] Africa [77] and China [78]. Despite tick blood meal being the most common transmission mode of TBPs, oral engulfment of infected ticks by animals, carnivorism, animal bites, and transplacental routes also occur to cause wildlife infection [2].…”

Tick-borne pathogens such as species of Borrelia, Babesia, Anaplasma, Rickettsia, and Ehrlichia are widespread in the United States and Europe among wildlife, in passerines as well as in domestic and farm animals. Transmission of these pathogens occurs by infected ticks during their blood meal, carnivorism, and through animal bites in wildlife, whereas humans can become infected either by an infected tick bite, through blood transfusion and in some cases, congenitally. The reservoir hosts play an important role in maintaining pathogens in nature and facilitate transmission of individual pathogens or of multiple pathogens simultaneously to humans through ticks. Tick-borne co-infections were first reported in the 1980s in white-footed mice, the most prominent reservoir host for causative organisms in the United States, and they are becoming a major concern for public health now. Various animal infection models have been used extensively to better understand pathogenesis of tick-borne pathogens and to reveal the interaction among pathogens co-existing in the same host. In this review, we focus on the prevalence of these pathogens in different reservoir hosts, animal models used to investigate their pathogenesis and host responses they trigger to understand diseases in humans. We also documented the prevalence of these pathogens as correlating with the infected ticks’ surveillance studies. The association of tick-borne co-infections with other topics such as pathogens virulence factors, host immune responses as they relate to diseases severity, identification of vaccine candidates, and disease economic impact are also briefly addressed here.

“…Carnivores are considered the first source of human infections with zoonotic agents, which include tick-borne pathogens [4][5][6]. Tick-borne pathogens have already been detected in coatis and associated ectoparasites from Brazil [7][8][9][10]. Theileria sp., Anaplasma bovis, Anaplasma sp.…”

“…closely related to A. phagocytophilum Ehrlichia sp., and hemoplasmas were detected in coatis from Pantanal wetland, Mato Grosso do sul state, central-western Brazil [7][8][9]. Recently, Rickettsia bellii and Rickettsia amblyommatis were detected in Amblyomma ovale and Amblyomma coelebs, respectively, from coatis sampled in Iguazu National Park, Iguazu Falls, Paraná state, southern Brazil [10]. Therefore, the constant surveillance of species, diversity and ecology of ectoparasites in wild animals is essential for monitoring vector-borne diseases.…”

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.

“…Otras causas de lesiones dermatológicas son las alteraciones metabólicas, nutricionales, genéticas, agresiones físicas o químicas (Novak & Meyer 2009). Las garrapatas por su parte pueden ser vectores de diversos patógenos que se benefician de las laceraciones y la pérdida de sangre de los huéspedes, desatando de forma crónica respuestas inmunes en los individuos afectados (Magalhães-Matos et al 2022). Enfermedades como la toxoplasmosis o la sarna, usualmente incluyen afecciones dermatológicas dentro de sus cuadros clínicos, y su detección temprana puede contribuir a prevenir y manejar adecuadamente estas enfermedades (Villalba-Briones et al 2022).…”

Entre junio 2020 y mayo 2021, se observó un individuo de Nasua nasua en la vereda “La Línea” del municipio de Apía y dos individuos de Potos flavus, uno en la vereda “Agua Linda”- Apía y otro en la vereda “La Esperanza” del municipio de Dosquebradas, los cuales presentaban afecciones cutáneas en diferentes regiones del cuerpo. Las causas de dichas afecciones no fueron descritas, no obstante, se propone estudiar la influencia de enfermedades transmitidas por animales domésticos como posible fuente de las afecciones cutáneas observadas.
