“…The serogroup Seramanga was the second most frequent in goats. It is considered non-pathogenic and associated with the presence of rodents and free-living animals in properties, such as whiteeared opossums (Didelphis albiventris), acting as sources of infection (SILVA et al, 2013;PAIXÃO et al, 2016). The Icterohaemorrhagiae is considered the second most frequent serogroup in sheep and is generally related to the presence of rodents, responsible for incidental infections in other hosts (ESCÓCIO et al, 2010;GENOVEZ et al, 2011).…”

The objective of this study was to determine the seroprevalence of leptospirosis and the predominant serogroups in serological tests of ruminants performed at the Transmissible Diseases Laboratory of the Federal University of Campina Grande, Patos, Paraíba, northeastern Brazil, between 2010 and 2017. This research included the records of serological tests for leptospirosis from 5594 animals, including 1527 cattle, 1761 goats, 2170 sheep, and 136 buffaloes from four Brazilian states (Paraíba, Pernambuco, Maranhão, and Rio Grande do Norte). Of the 5594 serum samples, 662 were serologically positive, corresponding to a frequency of 11.8%. Serjoe (30.6%), Autumnalis (13.6%), and Icterohaemorrhagiae (11.3%) were the most frequent subgroups among all species. The individual frequencies in cattle, goats, sheep, and buffaloes were 20% (306/1527), 8.3% (147/1761), 7.9% (171/2170), and 27.9% (38/136), respectively, with titers ranging from 1:100 to 1:3200. The most frequent serogroups according to animal species were as follows: Serjoe predominated in cattle (62%), followed by Icterohaemorrhagiae (12.5%) and Tarassovi (6.6%); Autumnalis was the most frequent in goats and sheep (29.4% and 26.9%, respectively), followed by Seramanga (12.5%) in goats and Icterohaemmorrhagiae (13.5%) in sheep; and Australis predominated in buffaloes (39.5%), followed by Pomona (31.6%) and Canicola (21.1%). Leptospira sp. infection, determined by serology, is widespread in ruminants (cattle, goats, sheep, and buffaloes) in northeastern Brazil, suggesting the existence of alternative transmission routes that are less dependent on environmental factors. Identification of the most frequent serogroups highlights the need to improve sanitary conditions, and implement efficient and targeted control measures directed at the primary infection sources.

“…We cannot confirm that the marsupials serve as a source of Leptospira infection, since the immune response in these animals is unknown. However, environmental disturbances can increase the proximity of these animals to urban areas and may promote the spread of pathogenic Leptospira to humans and domestic animals 7 .…”

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.

“…Serological surveys have also suggested that these animals might be potential reservoirs of Leptospira spp. (Valbuena-Torrealba and Péfaur-Veja 2015;Paixão et al 2014;Silva et al 2013;Ruiz-Piña et al 2002).…”

New records of Leptospira spp. in wild marsupials and a rodent in the eastern Brazilian Amazon through PCR detection

We analyzed the presence of Leptospira spp. in liver and kidney tissue of wild marsupials and rodents trapped in a periurban forest in the eastern Brazilian Amazon. We examined 25 individuals of four marsupial and seven rodent species for the presence of the 16S rRNA gene of Leptospira in the DNA extracted from 47 liver and kidney tissue samples using PCR. We detected positive samples in 12% (3/25) of the individuals, in kidney fragments of two marsupial species (Didelphis marsupialis and Marmosops pinheiroi) and in a liver fragment of one rodent species (Echimys chrysurus). These are the first records of Leptospira spp. in M. pinheiroi and E. chrysurus and it is the first molecular survey of marsupials and rodents in the Brazilian Amazon.
