Complexity and multi-factoriality of Trypanosoma cruzi sylvatic cycle in coatis, Nasua nasua (Procyonidae), and triatomine bugs in the Brazilian Pantanal. Repositório Alice
ALVES, F. M.; LIMA, J. S.; ROCHA, F. L.; HERRERA, H. M.; MOURAO, G.; JANSEN, A. M..
Trypanosoma cruzi is dispersed in nature through many transmission mechanisms among a high diversity of vectors and mammalian species, representing particular behaviors and habitats. Thus, each locality has a unique set of conditions underlying the maintenance of this parasite in the wild. The aim of the present study was to evaluate the life-cycle of T. cruzi in free-ranging coatis from the central region of the Brazilian Pantanal using a multi-factorial approach. Three methodological blocks were used in the present study: (i) We evaluated T. cruzi infection using serological (ELISA) and parasitological (hemoculture) tests in free-ranging coatis captured from October 2010 to March 2012. In addition, we characterized T. cruzi isolates as DTUs (Discrete...

Health and epidemiological approaches of Trypanosoma evansi and equine infectious anemia virus in naturally infected horses at southern Pantanal. Repositório Alice
PARREIRA, D. R.; JANSEN, A. M.; ABREU, U. G. P. de; MACEDO, G. C.; SILVA, A. R. S.; MAZUR, C.; ANDRADE, G. B.; HERRERA, H. M..
Equine infectious anemia virus (EIAV) and Trypanossoma evansi are endemic in Brazilian Pantanal Biome,an important area for livestock production. In this sense, we evaluated the epidemiological single andco-infection effects of T. evansi and EIAV in naturally infected horses in the southern Pantanal wetland byserological tests and hematological assays. Both higher seroprevalence and heath poor condition of thesampled animals were associated with differences in horse management between farms. We found thatthe negative animals for both infectious agents (NN) represented the major group in F1 (37%), and thesmallest group in F2 (19%). Furthermore, we recorded higher EIAV seroprevalence (56%) in F2, comparedto F1 (38%). We observed that T. evansi infection was...

Outcomes of Trypanosoma cruzi and Trypanosoma evansi infections on health of Southern coati (Nasua nasua), crab-eating fox (Cerdocyon thous), and ocelot (Leopardus pardalis) in the Brazilian Pantanal. Repositório Alice
SANTOS, F. M.; MACEDO, G. C. DE; BARRETO, W. T. G.; OLIVEIRA-SANTOS, L. G. R.; GARCIA, C. M.; MOURAO, G. de M.; PORFÍRIO, G. E. de O.; MARINO, E. D.; ANDRE, M. R.; PERLES, L.; OLIVEIRA, C. E. de; ANDRADE, G. B. de; JANSEN, A. M.; HERRERA, H. M..
The occurrence of Trypanosoma spp. in wild carnivore populations has been intensively investigated during the last decades. However, the impact of these parasites on the health of free-living infected animals has been largely neglected. The Pantanal biome is the world's largest seasonal wetland, harboring a great diversity of species and habitats. This includes 174 species of mammals, of which 20 belong to the order Carnivora. The present study aimed to investigate the effect of Trypanosoma evansi and Trypanosoma cruzi infections and coinfections on the health of the most abundant carnivores in the Pantanal: coati (Nasua nasua), crab-eating fox (Cerdocyon thous), and ocelot (Leopardus pardalis). We captured 39 coatis, 48 crab-eating foxes, and 19 ocelots....

Triatominae (Hemiptera, Reduviidae) in the Pantanal region: association with Trypanosoma cruzi, different habitats and vertebrate hosts. Repositório Alice
SANTOS, F. M.; JANSEN, A. M.; MOURAO, G.; JURBERG, J.; NUNES, A. P.; HERERRA, H. M..
The transmission cycle of Trypanosoma cruzi in the Brazilian Pantanal region has been studied during the last decade. Although considerable knowledge is available regarding the mammalian hosts infected by T. cruzi in this wetland, no studies have investigated its vectors in this region. This study aimed to investigate the presence of sylvatic triatomine species in different habitats of the Brazilian Pantanal region and to correlate their presence with the occurrences of vertebrate hosts and T. cruzi infection. Methods: The fieldwork involved passive search by using light traps and Noireau traps and active search by visual inspection. The light traps were placed at five selected points along forested areas for seven nights during each of the nine...
