“…A carência de fagócitos na urina proporciona a multiplicação desses microrganismos nos túbulos renais gerando microcolônias. Posteriormente as leptospiras passam a ser eliminadas na urina (leptospirúria), explicando assim a epidemiologia da leptospirose (Acha & Szyfres, 2005).…”

Leptospirosis is widespread throughout the world. In the bovine species, economic losses are mainly associated with reproductive failures. Due to its importance, the objective of the work was to determine the serovarieties most related to bovine leptospirosis in southwest Goiás, Brazil. 2,006 samples were collected in two slaughterhouses in 14 of the 18 municipalities in that region. For the diagnosis, the blood serum samples were submitted to the Microscopic Soroagglutination test (SAM), against 32 serovarieties of leptospires, adopting a positive titer greater than 100. A geographical distribution of the positive animals and the main serovarities present in the southwest of Goiás was carried out, and also a questionnaire with the producers, containing epidemiological information, the vaccine being one of the prophylactic measures related to the infection, on the other hand it was also observed that vaccinated animals they have also been shown to be reactive. It was noted 1,406 (70.1%) cattle were seroreactive for at least one of the 32 serovarieties of Lepstospira ssp. tested. The most frequent serovarieties were Guaricura (30.80%), Wolffi (30.51%), Shermani (9.39%), Hardjo (7.54%), Bananal (4.27%) and Pomona (3.27) %). Serranópolis (77.9%), Perolândia (75.5%), Caiapônia (74.7%) and Jataí (73.2%) are the municipalities with the highest frequency of seroreagent animals. Through this research, a high index of seroreactive animals from the studied region was demonstrated, reinforcing the importance of leptospirosis infection in the Southwest region of the State, being necessary, therefore, the implementation of general measures of control and infection of the animals.

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.
