“…Este sorovar possui maior frequência em seres humanos e está ligado a presença de roedores, podendo os bovinos se infectarem entrando em contato com alimentos ou água contaminada com a urina desses animais (Adler, 2015). Já as reações para o sorovar Canicola pode sugerir uma infecção cruzada entre os cães e bovinos, além disso, esses animais infectados podem gerar riscos zoonóticos para agricultores, ordenadores e trabalhadores rurais e de matadouros (Abdollahpour, et al, 2009, Balamurugan, et al, 2017, Sunder, et al, 2018. Por outro lado, a frequência do sorovar Grippotyphosa, assim como de sorovares Pomona, Tarassovi e Javanica podem ocorrer como consequência do contato direto e indireto, criações de gado em ambientes fechados onde há contato com outros lotes ou animais de outras espécies que atuam como reservatório de Leptospira (Guernier, et al, 2016).…”

No Brasil, a leptospirose bovina é uma enfermidade de grande preocupação, causando prejuízos econômicos à pecuária e um importante risco à saúde pública. Nos últimos anos, o Rio Grande do Sul se consolidou como importante exportador de gado vivo, refletindo diretamente na economia nacional. Nesse contexto, nosso estudo teve como objetivo determinar a prevalência de anticorpos anti-Leptospira em bovinos destinados à exportação, no município de Pelotas/RS. Para tanto, um total de 4.552 animais pertencentes a 34 municípios do RS foram incluídos no estudo. Uma amostragem estratificada foi realizada e uma amostra de 355 soros foram utilizados no teste de aglutinação microscópica (MAT). Dos 355 soros amostrados, 24 (6,76%; IC 95% 4,58-9,86) foram reativos para pelo menos um dos antígenos do MAT. Nenhum animal incluído no estudo tinha história de vacinação contra a leptospirose. Os sorovares Hardjo e Icterohaemorrhagiae tiveram prevalência de 2,53%, seguidos de Canicola com 1,97% e Grippotyphosa com 1,12%. Nossos resultados mostram a exposição dos bovinos ao agente, podendo levar a problemas de saúde pública, tendo em vista que a doença é uma zoonose. Pesquisas futuras podem utilizar nossos resultados para o planejamento de estudos epidemiológicos com o objetivo de descrever a situação da leptospirose em rebanhos bovinos no Rio Grande do Sul.

The article presents data on serological studies of 573 sera samples of cattle that were collected from the farms affected by leptospirosis in different regions of Ukraine in the period of 2014–2015. Samples were investigated by the microscopic agglutination test (MAT), which was conducted within eight serological groups of Leptospira and nine serovars: Sejroe (serovars polonica and hardjo), Hebdomadis (serovar kabura), Tarassovi (serovar tarassovi), Pomona (serovar pomona), Grippotyphosa (serovar grippotyphosa), Canicola (serovar canicola), Icterohaemorrhagiae (serovar copenhageni), and Australis (serovar bratislava). The circulation of L. interrogans serovar hardjo among cattle has been observed in all 11 regions of Ukraine investigated within 25.8–60.0% of the leptospirosis-positive serum samples in these regions.Antibodies in the cattle sera against serovar hardjo (serogroup Sejroe) were detected in 139 of the 370 cows reacting positively in MAT. Overall, they were detected in 24.3% animals out of the total of 573 cows investigated. These are the preliminary results, however, in our opinion, they should allow to include the serovar hardjo in a standard panel of strains for MAT in Ukraine.

“…According to the literature, at leptospirosis, disorders occurred in the functional state of the hepatobiliary and renal systems of horses (Holovakha, 2000), and pet animals (Kerr, 2005). In animals of other species, particularly cattle, this issue has not been sufficiently described (Sunder et al, 2017).…”

Changes in the biochemical parameters of blood in cows in the latent course of leptospirosis have been studied by the results of the reaction of microagglutination (RMA). The dynamics of biochemical blood parameters is manifested by hyperproteinemia, dysproteinemia, hemolytic anemia, hyperbilirubinemia, intra- and extrahepatic cholestasis, hyperfermentemia, mineral metabolism disorders, in particular hypocalcemia, hypophosphatemia, indicating the development of hepatopathy which should be classified as hepatocholangitis. It was determined that the pathological process is manifested in all animals for the titer of antibodies to one or another Leptospira serovar. Significant changes from the side of the hepatobiliary system in infested cows for the antibody titer kabura equaling 1:100, polonica 1:200, ballum 1:100, szvajzak 1:100–1:200, bratislava 1:800 and in animals for the titers kabura of 1:100–1:200; polonium 1:100; szvajzak 1:100–1:200; ballum 1:100; bratislava 1:100–1:200. At leptospirosis caused by bratislava and ballum serovars, a disorder of the functional state of the hepatobiliary system, characterized by an increase in the level of total protein, bilirubin, AST, GGTP and ALP activity was diagnosed as the urea, calcium and phosphorus levels in blood decreased. In the case of the latent course of the disease caused by kabura, polonica, szvajzak, ballumand bratislava serovars, a probably higher concentration of bilirubin, activity of aminotransferases (AST and ALAT), GGTP and ALP was determined in comparison to clinically healthy animals. In cows, in the presence of antibody titers kabura 1:100, polonica 1:200, ballum 1:100, szvajzak 1:100–1:200; bratislava 1:800, in 22.2% of cases, we recorded increase in the total protein against the background of dysproteinemia in 50.0–88.9% of animals, and increase in bilirubin in 78.6%, and increase in the activity of blood serum enzymes (AST, ALAT, GGTP, ALP), and also hypocalcemia and hypophosphatemia in 33.3–100.0%. The conducted studies indicate that in latent leptospirosis in cows, in addition to etiotropic therapy, one should include in the protocol the pharmacological correction preparations, which would contribute to the restoration of the functional state of the hepatobiliary system.
