  • Relationships between vector-borne parasites and free-living mammals at the Brazilian Pantanal
    Parasitology Research, 2021
    Co-Authors: Filipe Martins Santos, Marcos Rogério André, Keyla Carstens Marques De Sousa, Rosangela Zacarias Machado, Nayara Yoshie Sano, Wesley Arruda Gimenes Nantes, Sany Caroline Liberal, Heitor Miraglia Herrera
    Abstract:

    In nature, parasitic infections must be addressed as complex systems involving parasite-host relationships on a temporal and spatial scale. Since the parasites cover a great biological diversity, we can expect that wildlife are exposed simultaneously to different parasites. In this sense, the objective of this work was to determine the relationships between free-living mammals and their associated hemoparasites in the Brazilian Pantanal. We used the data published during 2017 and 2018 by de Sousa et al. regarding the detection of vector-borne pathogens (VBP), namely Anaplasma , Babesia , Bartonella , Cytauxzoon , Ehrlichia , Hepatozoon , Mycoplasma , and Theileria , in nine species of free-living mammals belonging to orders Carnivora, Rodentia, and Didelphimorphia. We assume as infected an individual positive on any of parasitological, molecular, and/or serological tests. We observed a strong association between the wild felid Leopardus pardalis with Cytauxzoon , the wild canid Cerdocyon thous with Hepatozoon , the small rodent Thrichomys fosteri with Bartonella , and the procyonid Nasua Nasua with Mycoplasma and Theileria . Therefore, N . Nasua , C . thous , T . fosteri , and the small rodent Oecomys mamorae can be considered key species for the maintenance of selected VBP in the Pantanal region, because they showed a high number of single and coinfections. Together, our results highlighted the importance of coinfection as a common phenomenon in nature.

  • Anaplasmataceae agents among wild mammals and ectoparasites in Brazil.
    Epidemiology and infection, 2017
    Co-Authors: Keyla Carstens Marques De Sousa, Heitor Miraglia Herrera, Rosangela Zacarias Machado, Ana Cláudia Calchi, J S Dumler, Darci Moraes Barros-battesti, Marcos Rogério André
    Abstract:

    Anaplasmataceae agents comprise obligate intracellular bacteria that can cause disease in humans and animals. Between August 2013 and March 2015, 31 Nasua Nasua (coati), 78 Cerdocyon thous (crab-eating fox), seven Leopardus pardalis (ocelot), 110 wild rodents, 30 marsupials, and 42 dogs were sampled in the Pantanal wetland, Brazil. In addition, ectoparasites found parasitizing the animals were collected and identified. The present work aimed to investigate the occurrence of Anaplasmataceae agents in wild mammals, domestic dogs and ectoparasites, by molecular and serological techniques. Overall, 14 (17·9%) C. thous, seven (16·6%) dogs and one (3·2%) N. Nasua were seroreactive to Ehrlichia canis. Nine dogs, two C. thous, one N. Nasua, eight wild rodents, five marsupials, eight Amblyomma sculptum, four Amblyomma parvum, 13 A. sculptum nymphal pools, two Amblyomma larvae pools and one Polygenis (Polygenis) bohlsi bohlsi flea pool were positive for Ehrlichia spp. closely related to E. canis. Seven N. Nasua, two dogs, one C. thous, one L. pardalis, four wild rodents, three marsupials, 15 A. sculptum, two Amblyomma ovale, two A. parvum and one Amblyomma spp. larval pools were positive for Anaplasma spp. closely related to A. phagocytophilum or A. bovis. The present study provided evidence that wild animals from Brazilian Pantanal are exposed to Anaplasmataceae agents.

  • Occurrence and molecular characterization of hemoplasmas in domestic dogs and wild mammals in a Brazilian wetland

    Abstract:

    Hemotropic mycoplasmas are known to cause anemia in several mammalian species. The present work aimed to investigate the occurrence of Mycoplasma spp. in wild mammals, domestic dogs and their respective ectoparasites, in southern Pantanal region, central-western Brazil. Between August 2013 and March 2015, 31 Nasua Nasua, 78 Cerdocyon thous, seven Leopardus pardalis, 42 dogs, 110 wild rodents, and 30 marsupials were trapped and ectoparasites (ticks and fleas) found parasitizing the animals were collected. Mammals and ectoparasites DNA samples were submitted to conventional PCR assays for Mycoplasma spp. targeting 16S rRNA and RnaseP genes. Twenty-four N. Nasua, three C. thous, two domestic dogs, one L. pardalis and one wild rodent were positive for 16S rRNA PCR protocols. Fourteen N. Nasua samples were also positive in RnaseP PCR. No marsupial or arthropod showed positivity for Mycoplasma spp. The phylogenetic analyses based on 16S rRNA gene showed that all sequences obtained from dogs, two sequences obtained from C. thous and ten sequences obtained from N. Nasua showed to be closely related to Mycoplasma haemocanis/Mycoplasma haemofelis species. Genotypes closely related to 'Candidatus Mycoplasma haemominutum' and Mycoplasma haemomuris were detected in the L. pardalis and in the wild rodent, respectively. Probably a novel Mycoplasma genotype, closely related to a sequence obtained from a Brazilian capybara was detected in 14 N. Nasua, based on a concatenated phylogenetic analysis of 16S rRNA and RnaseP genes. The present study revealed that wild animals in southern Pantanal region, Brazil, are exposed to different species of hemoplasmas.

  • modulating variables of trypanosoma cruzi and trypanosoma evansi transmission in free ranging coati Nasua Nasua from the brazilian pantanal region

  • Experimental Trypanosoma evansi infection in South American coati (Nasua Nasua): hematological, biochemical and histopathological changes.
    Acta tropica, 2002
    Co-Authors: Heitor Miraglia Herrera, Antonio Carlos Alessi, Luiz Carlos Marques, A.e Santana, L.p.c.t Aquino, R.f Menezes, M.a.v Moraes, R. Z. Machado
    Abstract:

    The course of an experimental Trypanosoma evansi infection in coatis (Nasua Nasua, carnivora, Procyonidae) was followed for 262 days. Hematological analysis of the infected coatis revealed a marked decline in hemoglobin, packed-cell volume, and total erythrocyte count. An intense anemia followed the first wave of parasitemia and persisted until the end of the experimental period. Biochemical analysis showed increased serum levels of alanine aminotransferase and aspartate aminotransferase and decreased albumin. The main histopathological features consisted of myocarditis with the presence of degenerate cardiac fibers and meningoencephalitis. This study has shown that coatis infected with T. evansi develop a chronic disease.

  • The communicative life of a social carnivore: acoustic repertoire of the ring-tailed coati (Nasua Nasua)
    2018
    Co-Authors: Aline Gasco, Humberto F. Ferro, Patrícia Ferreira Monticelli
    Abstract:

    The coati is a highly social mammal that features sophisticated cognitive and social abilities. We hypothesized that the ring-tailed coati, Nasua Nasua, uses an extensive acoustic repertoire that correlates to their diverse range of social interactions. We tested this hypothesis by observing and recording a free-ranging managed population of N. Nasua in Tietê Ecological Park (PET), in the municipality of São Paulo, State of São Paulo, Brazil. Of 404 h of sampling, 47 h of coati vocalizations were recorded over 3 years. Additional records were obtained opportunistically on other free-living populations at PET by using passive acoustic monitoring. We describe here an acoustic repertoire composed of 15 calls (12 basic calls, 2 rhythmic calls and the non-random complex calls composed of three or four different units). This diverse repertoire of signals was used in contact/cohesion regulation, foraging activities, alert or potential threat situations, playing and fighting interactions and during social isolation and acute distress. The contact call (chirp) is produced through biphonation, and other non-linear phenomena are present. Our study found a complex vocal repertoire that encourages further studies to describe the evolution of the cognitive characteristics and social abilities of ring-tailed coatis.

  • Hematological mean values of coatis (Nasua Nasua) infected with Trypanosoma evansi (TE), Trypanosoma cruzi (TC), and in coinfected (TE/TC) animals in the sub-region of Nhecolândia, Pantanal, between November 2015 and October 2016.
