A four-year longitudinal study of the structure sylvatic transmission cycles Trypanosoma cruzi , reservoir host competence and parasite discrete typing units was conducted in a disturbed rural area humid Chaco Argentina. Among 190 mammals examined by xenodiagnosis polymerase chain reaction amplification, composite prevalence infection substantially higher Dasypus novemcinctus armadillos (57.7%) Didelphis albiventris opossums (38.1%) than Euphractus sexcinctus (20.0%), Tolypeutes matacus...
We conducted a cross-sectional survey of Trypanosoma cruzi infection Triatoma infestans as well dogs and cats in 327 households from well-defined rural area northeastern Argentina to test whether the household distribution differed between local ethnic groups (Tobas Creoles) identify risk factors for host infection. Overall prevalence bugs (27.2%; 95% confidence interval = 25.3-29.3%), (26.0%; 23.3-30.1%), examined (28.7%; 20.2-39.0%) was similar. A multimodel inference approach showed that...
Abstract Mortality events of marsh deer ( Blastocerus dichotomus ) have been historically described in the southern margins its geographical range. Few documented cases show how environmental changes and pathogens interact to trigger mortality scenarios reveal their causes. Here, using a participatory surveillance framework, we document most extensive event observed last three decades occurring Ibera ecoregion, Corrientes, Argentina. Local stakeholders monitored disease or mortality, upon...
El zorro de monte se distribuye en el noreste y centro la Argentina, incluyendo diversas áreas protegidas, siendo su registro más austral Delta bonaerense. Este trabajo presenta los primeros cinco avistajes especie Parque Nacional Ciervo Pantanos (Campana, Buenos Aires, Argentina), que representan registros australes hasta fecha confirman presencia 19 protegidas nacionales. Estos hallazgos añaden un nuevo carnívoro a lista del respaldan evidencia migración nuevas especies hacia Paraná.
As a significant zoonotic disease, rabies poses substantial economic challenges for the livestock sector, highlighting need effective wildlife monitoring as part of One Health approach. This study documents first case paralytic in lowland tapir (Tapirus terrestris) at Guaycolec Wildlife Station Formosa, Argentina. The 12-year-old male exhibited neurological symptoms, including limb paralysis and dysphagia, leading to its death. virus was confirmed through direct immunofluorescence, isolation...
The discrete typing units (DTUs) of Trypanosoma cruzi that infect domestic dogs and cats have rarely been studied. With this purpose we conducted a cross-sectional xenodiagnostic survey dog cat populations residing in 2 infested rural villages Pampa del Indio, the humid Argentine Chaco. Parasites were isolated by culture from 44 12 with positive xenodiagnosis. DTUs identified parasite samples using strategy based on multiple polymerase-chain reactions. TcVI was 37 10 cats, whereas TcV 5 -a...
A near-threatened species, the maned wolf's (Chrysocyon brachyurus) range extends from central Brazil, northern and eastern Bolivia, southeastern Peru to southeast of Gran Chaco ecoregion adjacent scrubland in Argentina. Rural domestic dogs under ownership may pose threats wolves as reservoir hosts multiple pathogens. serologic survey rural was conducted document exposure canine pathogens Santiago del Estero, Argentina, with a parallel questionnaire knowledge, attitudes, perception local...
Abstract Background In an era of unprecedented socio-ecological changes, managing wildlife health demands high-quality data collection and the engagement local communities. Blastocerus dichotomus , largest South American deer, is Vulnerable to extinction mainly due habitat loss. Diseases have been recognised as a potential threat, winter mortality has historically described in marsh deer populations from Argentina. Field difficulties have, however, prevented in-depth studies their status....
The distribution of parasite load across hosts may modify the transmission dynamics infectious diseases. Chagas disease is caused by a multi-host protozoan, Trypanosoma cruzi, but association between host parasitemia and infectiousness to vector has not been studied in sylvatic mammalian hosts. We quantified T. cruzi mammals, modeled with compared these results previous ones for local domestic bloodstream each 28 naturally infected mammals from six species captured northern Argentina was...
Vector-borne pathogens are responsible for serious emerging diseases and have been widely described in wildlife. Ehrlichia chaffeensis causes the zoonotic "monocytic ehrlichiosis" humans, is transmitted by tick Amblyomma americanum its reservoir host white-tailed deer (Odocoileus virginianus) North America. Little known about native vectors involved transmission cycle South We report here detection of E. a study on marsh (Blastocerus dichotomus) mortality Argentina, different time periods...
The marsh deer (Blastocerus dichotomus) is the largest South American native species and listed as "Vulnerable" by IUCN due to population reduction. As part of a conservation disease surveillance program, muscle samples from 14 found dead in 2016 2017 northeast Argentina were obtained at necropsy. Samples each animal processed pooled muscles (heart, diaphragm, tongue hindlimb) homogenization direct microscopical observation detect intracellular Sarcocystis spp. cysts. Sarcocysts observed six...
The transmission of pathogens between domestic dogs and generalist wildlife species may be modified by environmental degradation, biodiversity losses, host densities, increased contact rates in remnant forest patches. A serologic survey canine parvovirus (CPV) rural wild mammals was conducted two neighboring areas (disturbed protected) from Pampa del Indio, northeastern Argentina, 2008 2011. total 174 26 mammals—4 crab-eating foxes (Cerdocyon thous), 3 raccoons (Procyon cancrivorus), 17...
Abstract Vaccines to prevent Trypanosoma cruzi infection in humans or animals are not available, and many settings, dogs an important source of domestic for the insect vector. Identification infected canines is crucial evaluating peridomestic transmission dynamics parasite control strategies. As immune T. dependent on humoral cell-mediated responses, we aimed define a serodiagnostic assay T cell phenotypic markers identifying studying canine -specific response. Plasma samples peripheral...
SUMMARY Establishing the putative links between sylvatic and domestic transmission cycles of Trypanosoma cruzi , etiological agent Chagas disease, is public health relevance. We conducted three surveys to assess T. infection in wild mammals from a rural preserved area Misiones Province, Northeastern Argentina, which had recently been declared free vector- blood-borne human infection. A total 200 were examined by xenodiagnosis (XD) and/or polymerase chain reaction (PCR) amplification...
Anaplasma marginale is a well-known cattle pathogen of tropical and subtropical world regions. Even though, this obligate intracellular bacterium has been reported in other host species different than bovine, it never documented Myrmecophaga tridactyla (giant anteater) or Hippocamelus antisense (taruca), which are two native endangered species. Samples from sick wild animals: (blood) (blood serum) were studied for the presence A. DNA through msp5 gene fragment amplification. Further...
