A serological survey in free-ranging crab-eating foxes (Canidae: Cerdocyon thous) and brown-nosed coatis (Procyonidae: Nasua nasua) was performed in the Nhecolândia sub-region of the Brazilian Pantanal to evaluate the presence of anti-smooth Brucella antibodies on those wild populations. The detection of anti-smooth Brucella antibodies was performed by the Rose Bengal Test (RBT) as screening test and the Fluorescence Polarization Assay (FPA) as a confirmatory test. The frequency of smooth Brucella seropositive animals were 13.2% (5/38, 95% CI: 4.4% - 28.1%) for crab-eating foxes and 8.8% (3/34, 95% CI: 1.9% -23.7%) for brown-nosed coatis. No association was found between seropositivity for brucellosis and gender or age. The results of this study suggest exposure to or infection of crab-eating fox and brown-nosed coati from the Brazilian Pantanal by Brucella spp

Granulomatous Pneumonia

ABSTRACT: Pythiosis is an emerging infectious disease affecting captive and free-ranging wild animals. We report granulomatous pneumonia due to Pythium insidiosum in two South American coatis (Nasua nasua), who were found dead without any clinical records. Severe granulomatous pneumonia associated with pleural effusion was revealed in the necropsy. Microscopically, variably sized granulomas and pyogranulomas presented negative hyphae profiles at the periphery of their necrotic cores. Grocott methenamine silver stain highlighted these structures, and immunostain (anti- P. insidiosum) was strongly positive. Molecular analysis by polymerase chain reaction amplified P. insidiosum specific DNA. These findings characterized P. insidiosum as a cause of granulomatous pneumonia in coatis and proved that pythiosis needs to be considered in the differential diagnosis of respiratory diseases affecting this species in endemic areas.

Abstract Host infection by parasites is influenced by an array of factors, including host and environmental features. We investigated the relationship between host sex, body size and age, as well as seasonality on infection patterns by acanthocephalan in coatis (Procyonidae: Nasua nasua) and in crab-eating foxes (Canidae: Cerdocyon thous ) from the Brazilian Pantanal wetlands. Between 2006 and 2009, we collected faecal samples from these hosts and analyzed for the presence of acanthocephalan eggs. Prevalence, abundance and intensity of eggs of acanthocephalans were calculated. Egg abundance was analyzed using generalized linear models (GLM) with a negative binomial distribution and models were compared by Akaike criteria to verify the effect of biotic and abiotic factors. Prevalence of acanthocephalans was higher in the wet season in both host species but did not differ between host sexes; however, adult crab-eating foxes showed higher prevalence of acanthocephalan eggs than juveniles. In contrast, prevalence of acanthocephalan eggs found in coatis was higher in coati juveniles than in adults. Host age, season and maximum temperature were the top predictors of abundance of acanthocephalan eggs in crab-eating foxes whereas season and host sex were predictors of egg abundance in coatis. The importance of seasonality for abundance of acanthocephalan was clear for both host species. The influence of host-related attributes, however, varied by host species, with host gender and host age being important factors associated with prevalence and parasite loads.

SUMMARYAnaplasmataceae agents comprise obligate intracellular bacteria that can cause disease in humans and animals. Between August 2013 and March 2015, 31Nasua nasua(coati), 78Cerdocyon thous(crab-eating fox), sevenLeopardus 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. nasuawere seroreactive toEhrlichia canis. Nine dogs, twoC. thous,oneN. nasua, eight wild rodents, five marsupials, eightAmblyomma sculptum,fourAmblyomma parvum,13A. sculptumnymphal pools, twoAmblyommalarvae pools and onePolygenis (Polygenis) bohlsi bohlsiflea pool were positive forEhrlichiaspp. closely related toE. canis. SevenN. nasua, two dogs, oneC. thous,oneL. pardalis, four wild rodents, three marsupials, 15A. sculptum, twoAmblyomma ovale,twoA. parvumand oneAmblyommaspp. larval pools were positive forAnaplasmaspp. closely related toA. phagocytophilumorA. bovis. The present study provided evidence that wild animals from Brazilian Pantanal are exposed to Anaplasmataceae agents.
