5. Detection of antibodies against Leptospira spp in free-living marsupials caught in the Eastern Amazon
Abstract 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,

6. Serological and molecular detection of Leptospira spp in dogs
Abstract INTRODUCTION: This study aimed to detect anti-Leptospira spp antibodies and Leptospira DNA in domestic dogs. METHODS: Blood and urine from 106 dogs were evaluated by microscopic agglutination test (MAT) and polymerase chain reaction (PCR), respectively. RESULTS: Six (5.7%) and one (1%) animals were positive by MAT and PCR, respectively. CONCL

7. Serosurvey of Leptospira spp. and Toxoplasma gondii in rats captured from two zoos in Southern Brazil
Abstract INTRODUCTION: Norway rats (Rattus norvegicus) are zoonotic reservoirs for Leptospira spp. and Toxoplasma gondii, and influence diseases in urban areas. METHODS: Free-ranging and laboratory-raised rats from two zoos in southern Brazil were tested for Leptospira spp. and T. gondii using microscopic agglutination and modified agglutination tests, r

8. Diagnostic utility of an immunochromatography test for the detection of Leptospira IgM antibodies in domestic dogs
ABSTRACT: A cross-sectional study using 99 serum samples of dogs from southern Chile was conducted to determine the diagnostic utility of a rapid immunochromatography assay for the detection of Leptospira specific IgM antibodies as screening test and as a potential aid in the diagnosis of leptospirosis in animals with and without clinical suspicion of the di

9. Seroprevalence of and risk factors for leptospirosis in the City of Manaus, State of Amazonas, Brazil
Abstract INTRODUCTION Leptospirosis is caused by a bacterium of the genus Leptospira. This study aimed at investigating the seroprevalence of and risk factors for leptospirosis in humans in Manaus, State of Amazonas. METHODS Interviews were performed, and 1,000 blood serum samples were examined using a microscopic agglutination test. RESULTS Forty-thre

10. Anti-leptospirosis agglutinins in Brazilian capybaras (hydrochoerus hydrochaeris)
Abstract Background The 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. Methods Due to the economic importance of this species and the lack of studies

11. Molecular characterisation and disease severity of leptospirosis in Sri Lanka
Leptospirosis is a re-emerging zoonotic disease all over the world, important in tropical and subtropical areas. A majority of leptospirosis infected patients present as subclinical or mild disease while 5-10% may develop severe infection requiring hospitalisation and critical care. It is possible that several factors, such as the infecting serovar, level of

12. Leptospirosis in animals and human contacts in Egypt: broad range surveillance
INTRODUCTION: Leptospirosis is a re-emerging zoonotic disease of humans and animals worldwide. The disease is caused by pathogenic species of the genus Leptospira. These organisms are maintained in nature via chronic renal infection of carrier animals, which excrete the organisms in their urine. Humans become infected through direct or indirect exposure to
