“…In wild animals, specific climatic, edaphic and hydrological factors also determine the incidence of leptospirosis in different habitats [ 42 ]. Differences in prevalence and serovars between studies in wildlife could be due to inconsistencies in cutoff titres, serovars tested, sampling site characteristics, climate or geographic location and timing of the year of the study [ 43 ].…”

A total of 249 serum samples from 13 wild animal species namely fallow deer (Dama dama, n = 1), roe deer (Capreolus capreolus, n = 80), red deer (Cervus elaphus, n = 22), chamois (Rupicapra rupicapra, n = 21), mouflon (Ovis musimon, n = 4), brown hare (Lepus europaeus, n = 2), nutria (Myocastor coypus, n = 1), red fox (Vulpes vulpes, n = 97), stone marten (Martes foina, n = 12), European badger (Meles meles, n = 2), golden jackal (Canis aureus, n = 2) Eurasian lynx (Lynx lynx, n = 2) and grey wolf (Canis lupus, n = 3) were analysed for the presence of antibodies against Leptospira interrogans sensu stricto. Serum samples were examined via the microscopic agglutination test for the presence of specific antibodies against Leptospira serovars Icterohaemorrhagiae, Bratislava, Pomona, Grippotyphosa, Hardjo, Sejroe, Australis, Autumnalis, Canicola, Saxkoebing and Tarassovi. Antibodies to at least one of the pathogenic serovars were detected in 77 (30.9%; CI = 25–37%) sera. The proportion of positive samples varied intraspecifically and was the biggest in large carnivores (lynx, wolf and jackal; 86%), followed by mezzo predators: stone marten (67%) and red fox (34%), and large herbivores: red deer (32%), roe deer (25%), alpine chamois (10%) and mouflon (0%). Out of the 77 positive samples, 42 samples (53.8%) had positive titres against a single serovar, while 35 (45.4%) samples had positive titres against two or more serovars. The most frequently detected antibodies were those against the serovar Icterohaemorrhagiae. The present study confirmed the presence of multiple pathogenic serovars in wildlife throughout Slovenia. It can be concluded that wild animals are reservoirs for at least some of the leptospiral serovars and are a potential source of leptospirosis for other wild and domestic animals, as well as for humans.

“…Unlike clinical disease seen in canines and humans, the health impact of leptospirosis in wildlife is unclear [ 43 ]. Necropsy of fresh carcasses of animals killed in traffic accidents to look for renal lesions [ 19 ] and collection of tissue for immunohistochemistry would help in confirming the disease [ 82 ].…”

Leptospirosis is a re-emerging zoonotic infectious disease caused by pathogenic bacteria of the genus Leptospira. Regional differences in the disease manifestation and the role of ecological factors, specifically in regions with a subarctic and arctic climate, remain poorly understood. We here explored environmental and socio-economic features associated with leptospirosis cases in livestock animals in the Russian Arctic during 2000–2019. Spatial analysis suggested that the locations of the majority of 808 cases were in “boreal” or “polar” climate regions, with “cropland,” “forest,” “shrubland,” or “settlements” land-cover type, with a predominance of “Polar Moist Cropland on Plain” ecosystem. The cases demonstrated seasonality, with peaks in March, June, and August, corresponding to the livestock pasturing practices. We applied the Forest-based Classification and Regression algorithm to explore the relationships between the cumulative leptospirosis incidence per unit area by municipal districts (G-rate) and a number of socio-economic, landscape, and climatic factors. The model demonstrated satisfactory performance in explaining the observed disease distribution (R2 = 0.82, p < 0.01), with human population density, livestock units density, the proportion of crop area, and budgetary investments into agriculture per unit area being the most influential socio-economic variables. Climatic factors demonstrated a significantly weaker influence, with nearly similar contributions of mean yearly precipitation and air temperature and number of days with above-zero temperatures. Using a projected climate by 2100 according to the RCP8.5 scenario, we predict a climate-related rise of expected disease incidence across most of the study area, with an up to 4.4-fold increase in the G-rate. These results demonstrated the predominant influence of the population and agricultural production factors on the observed increase in leptospirosis cases in livestock animals in the Russian Arctic. These findings may contribute to improvement in the regional system of anti-leptospirosis measures and may be used for further studies of livestock leptospirosis epidemiology at a finer scale.

A leptospirose é uma zoonose de grande importância em saúde pública. Cento e quatro (104) amostras de urina de bovinos abatidos na região centro-oeste do Estado de São Paulo, Brasil, foram avaliadas para detectar Leptospira spp. As amostras foram mantidas em PBS e em culturas de EMJH e Fletcher. Observamos crescimento de microrganismos em 13 amostras do meio Fletcher, embora não tenha sido observado no meio EMJH. Por PCR, 25 animais (amostras) foram positivos com os primers LEP1 / LEP2, sendo que 16 amostras foram mantidas em PBS, seis em meio Fletcher e três em meio EMJH. As 25 amostras foram submetidas a PCR com o gene LipL32 para verificação da patogenicidade. Uma amostra amplificada e por sequenciamento resultou em 99,77% de similaridade com Leptospira kirschneri sorovar Canicola e Leptospira interrogans sorovar Pyrogenes. Este é o primeiro relato de isolamento de Leptospira kirschneri sorovar Canicola e Leptospira interrogans sorovar Pyrogenes em amostra de urina bovina na Região Centro-Oeste do estado de São Paulo, Brasil. Concluímos a importância da leptospirose no rebanho avaliado e a atenção para o risco ocupacional, devido à possibilidade de urina contaminada nas pastagens e disseminação da infecção para outros animais e pessoas contactantes.
