25. Efficacy of leptospiral commercial vaccines on the protection against an autochtonous strain recovered in Brazil
Abstract In swine and bovines, leptospirosis prevention and control is carried out via vaccination of susceptible animals using bacterins. However, the efficiency of leptospirosis vaccines has been questioned. This work aimed to investigate the potency of five leptospirosis vaccines sold commercially in Brazil, challenging the animals with one autochthonous

26. 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

27. 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,

28. Pathology and pathogenesis of human leptospirosis: a commented review
ABSTRACT Leptospirosis is an acute bacterial septicemic febrile disease caused by pathogenic leptospires, which affect humans and animals in all parts of the world. Transmission can occur by direct contact with infected animals or, more commonly, through indirect contact with water or soil contaminated with urine from infected animals. Leptospires enter the

29. Comparative genomics of pathogenic Leptospira interrogans serovar Canicola isolated from swine and human in Brazil
Leptospira interrogans serovar Canicola is one of the most important pathogenic serovars for the maintenance of urban leptospirosis. Even though it is considered highly adapted to dogs, serovar Canicola infection has already been described in other animals and even a few human cases. Here, we present the genomic characterisation of two Brazilian L. interroga

30. Whole-genome sequencing of Leptospira interrogans from southern Brazil: genetic features of a highly virulent strain
BACKGROUND Leptospirosis is the most widespread zoonotic disease. It is caused by infection with pathogenic Leptospira species, of which over 300 serovars have been described. The accurate identification of the causative Leptospira spp. is required to ascertain the pathogenic status of the local isolates. OBJECTIVES This study aimed to obtain the complete

31. Characterization of Leptospira isolates from humans and the environment in Uruguay
ABSTRACT Laboratory diagnosis of human leptospirosis usually relies on indirect methods exploring specific immune response. Isolation and identification of the involved strains are cumbersome, but can provide biological resources for pathogenic studies and relevant information for guiding prevention and control measures. The aim of the research we are hereby

32. Human leptospirosis in the Federal District, Brazil, 2011-2015: eco-epidemiological characterization
Abstract INTRODUCTION: Leptospirosis is an infectious disease that affects more than 5,000 people per year in Brazil. The Federal District (FD) lacks epidemiological studies of human leptospirosis and presents concerning rates of this disease, especially considering its lethality. METHODS: Seventy-nine autochthonous human cases of leptospirosis between 201

34. First serologic evidence of human hantavirus infection in Alagoas State in Northeastern Brazil
Abstract INTRODUCTION: Hantavirus cardiopulmonary syndrome (HCPS) is rare in Northeastern Brazil. METHODS: Prospective surveillance was conducted over a two-year period in Alagoas State, Northeastern Brazil. The prevalence of anti-hantavirus N-antigen IgM and IgG in human serum samples was determined by enzyme-linked immunosorbent assay testing. RESULTS

35. Human leptospirosis: occurrence of serovars of Leptospira spp. in the state of Minas Gerais, Brazil, from 2008 to 2012
Abstract Background: Leptospirosis is an infectious and acute disease caused by Leptospira spp. that have high epidemic potential. This study verified the main Leptospira spp. serovars detected by MAT from serum of patients with suspicion of leptospirosis from 2008 to 2012 in Minas Gerais State. Methods: The laboratory received sera from 4654 patients. All

36. 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
