1. Seroprevalence of Leptospira spp. infection in sheep from northwest of Rio Grande do Sul, Brazil
RESUMO: A leptospirose é uma zoonose amplamente distribuída em países tropicais. Essa infecção também está associada a perdas reprodutivas na pecuária, apresentando uma relevância econômica notável. O objetivo deste estudo foi investigar a soroprevalência e os fatores de risco associados à infecção por leptospirose em rebanhos comerciais de ov

2. Risk factors associated with leptospirosis in swine in state of Pernambuco, Brazil
RESUMO: A leptospirose é um grande problema de saúde pública, e os suínos são um dos mais importantes reservatórios e fonte de infecção por Leptospira para o homem. O objetivo deste estudo foi investigar a situação epidemiológica da leptospirose em suínos no estado de Pernambuco, Brasil. Amostras de sangue de 265 suínos foram coletadas e testada

4. 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

5. 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

6. 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,

7. 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

8. 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

9. 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

10. Genetic diversity of Leptospira in northwestern Colombia: first report of Leptospira santarosai as a recognised leptospirosis agent
The region of Antioquia in northeastern Colombia has the highest number of reported leptospirosis cases in the country. It also shows high seroprevalence indexes in the general population and socio-environmental conditions favourable for the transmission of the disease between humans and animals. In this study, 25 Leptospira isolates from Colombia’s Antioq

11. Immune response in hamsters immunised with a recombinant fragment of LigA from Leptospira interrogans, associated with carrier molecules
Immunisation with the C-terminal region of leptospiral immunoglobulin-like A protein (LigANI) has shown promising results against leptospirosis. We evaluated the humoral immune response and protection induced by LigANI associated with carboxyl multi-walled carbon nanotubes (COOH-MWCNTs), CpG oligodeoxynucleotides (CpG ODNs), or Alhydrogel. Animals immunised

12. COMPARISON OF 16S rRNA-PCR-RFLP, LipL32-PCR AND OmpL1-PCR METHODS IN THE DIAGNOSIS OF LEPTOSPIROSIS
SUMMARY Leptospirosis is still one of the most important health problems in developing countries located in humid tropical and subtropical regions. Human infections are generally caused by exposure to water, soil or food contaminated with the urine of infected wild and domestic animals such as rodents and dogs. The clinical course of leptospirosis is variab
