“…Accordingly, they are common in cities, with substantial litter, which favors the spread of zoonoses, such as leptospirosis 4 . Therefore, in the present study, anti-Leptospira antibodies were examined in free-living marsupials in the municipalities of Peixe-Boi (01º11'31 "S, 47º18'44" W), Castanhal (07º20'53 "S, 50º23'45" W), and Viseu (01º11'48 "S, 46º08'24" W) within the metropolitan mesoregion of Belém and Northeast Pará, Brazil.…”

Introduction: Serological surveys are important to assess the health status of wild animals. In this study, antibodies against Leptospira spp, causal agents of leptospirosis, were detected in free-living marsupials in the State of Pará, Brazil. Methods: Nineteen blood samples collected from marsupials in the municipalities of Peixe-Boi, Viseu, and Castanhal were subjected to microscopic agglutination tests. Results: In total, 36.8% (7/19) of samples were positive, and two exhibited coagglutination. The most frequent serovars were Icterohaemorrhagiae (60%; 3/5), Panama (20%; 1/5), and Nupezo (20%; 1/5). Conclusions: Anti-Leptospira spp antibodies currently circulate in free-living marsupials in Northeastern Pará.

“…Among the species that occur in Brazil, two can be easily found in the great Brazilian biomes, D. aurita (black-eared opossum) and D. albiventris (white-eared opossum) (Aléssio et al, 2005;Moura et al, 2009;Paglia et al, 2012). These mammals have opportunistic habits, and can live in wild, rural and urban environments, maintaining contact with other animals and human beings (Lucheis et al, 2009;Tarragona et al, 2011). Notably, white-eared opossum is widely distributed in Brazilian biomes and is strongly adapted to highly degraded areas, as well as urban forest fragments (Aléssio et al, 2005).…”

Many emerging infectious diseases are zoonotic and transmitted by an arthropod vector; thus, the Global One Health perspective is necessary for a better understanding of these diseases. Bartonellosis, one of those emerging infectious diseases, is caused by bacteria of the genus Bartonella, and can have different clinical manifestations in humans and animals. Opossums and their ectoparasites have been linked to human-wildlife conflicts. Knowing this, we aimed to evaluate infection by Bartonella spp. in free-living opossums seized or rescued from Atlantic Forest biome of Rio de Janeiro (southeastern Brazil). Whole blood was obtained from seven Didelphis aurita and eight D. albiventris, and DNA was assessed by conventional and quantitative polymerase chain reactions (PCR and qPCR). Positivity was achieved in 40.0% (PCR) and 46.7% (qPCR) of the samples, revealing, possibly for the first time, the presence of Bartonella spp. DNA in opossums from peri-urban areas of Atlantic Forest biome. Studies should continue, in order to elucidate synanthropic mammals importance in bartonellosis epidemiology.

“…Leptospirosis can be transmitted directly through contact with secretions, blood or urine of infected animals or indirectly through the contact with water contaminated mainly with urine of carriers [ 13 ]. Many domestic and wild animals get infected and become renal carriers and potential shedders of the agent [ 5 , 14 , 15 ]. Evidence of renal Leptospira spp.…”

BackgroundThe interest in commercial use of wild animals is increasing, especially regarding raising of capybaras. Although this wild species is potentially lucrative for the production of meat, oil and leather, it is suggested as a probable reservoir of leptospires.MethodsDue to the economic importance of this species and the lack of studies concerning leptospirosis, the presence of anti-leptospirosis agglutinins was assayed in 55 serum samples of capybaras (Hydrochoerus hydrochaeris) from commercial and experimental breeding flocks located in São Paulo state, Paraná state, and Rio Grande do Sul state, Brazil. Samples were obtained through cephalic or femoral venipunction (5 to 10 mL). Microscopic agglutination test was used according to the Brazilian Health Ministry considering as cut-off titer of 100.ResultsOut of the 55 samples analyzed, 23 (41.82 %) tested positive. The most prevalent serovar was Icterohaemorrhagiae (56.52 %) in 13 samples, followed by Copenhageni in nine samples (39.13 %), Pomona in four samples (17.39 %), Djasiman and Castellonis in three samples each (13.04 %), Grippotyphosa, Hardjo, Canicola, and Cynopteri in two samples each (8.7 %), and Andamana and Bratislava in one sample each (4.34 %).ConclusionsThese results suggest the evidence of exposure to Leptospira spp. and the need of new studies to evaluate a higher number of capybaras from different regions to better understand the importance of leptospirosis infection in these animals and verify the zoonotic role of this species as a possible source of infection to humans and other animals.
