1. Biomechanical and biochemical investigation of erythrocytes in late stage human leptospirosis
Leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira, which can cause lipid changes in the erythrocyte membrane. Optical tweezers were used to characterize rheological changes in erythrocytes from patients with leptospirosis in the late stage. Biochemical methods were also used for quantification of plasma lipid, erythrocyte membran

3. Diagnosis of canine leptospirosis: evaluation of two PCR assays in comparison with the microagglutination test
RESUMO: O diagnóstico definitivo da leptospirose canina é geralmente realizado demonstrando a seroconversão em amostras do paciente no período agudo e de convalescença por serologia. No entanto, a aplicação de técnicas de PCR pode contribuir para a confirmação de casos suspeitos num período de tempo mais curto. O objetivo deste estudo foi avaliar

4. Environmental and socioeconomic determinants of leptospirosis incidence in Colombia
A leptospirose humana é uma infecção que majoritariamente afeta países tropicais. Desde 2007, a notificação da doença é compulsória na Colômbia, o que levou a um aumento do número de casos nos últimos anos. Os objetivos foram analisar variáveis ambientais e socioeconômicas e avaliar sua relação com casos de leptospirose humana. Foi feito um e

6. Socio-epidemiological characterization of human leptospirosis in the Federal District, Brazil, 2011-2015
Abstract INTRODUCTION: Human leptospirosis (HL) in the Federal District (DF), Brazil, is endemic and requires studies to characterize the socio-epidemiological profile of the vulnerable population. METHODS: Seventy-nine autochthonous cases of HL between 2011-2015 were analyzed based on the databases of the Epidemiological and Environmental Health Surveilla

7. 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

8. 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

9. 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

10. 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

11. 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

12. ELISA IgM para diagnóstico de leptospirose: revisão sistemática e meta-análise
Resumo O objetivo desta revisão sistemática e meta-análise foi avaliar a acurácia do ELISA IgM para o diagnóstico precoce da leptospirose em humanos. A busca foi realizada nas seguintes bases de dados: Medline, PubMed, LILACS, Embase e Cochrane Central Register of Controlled Trials e Grey literature (Google Scholar and British Library).
