1. 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

3. 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

4. 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

5. 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

6. 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

7. Leptospira spp. infection in sheep herds in southeast Brazil
Background With the aim of studying Leptospira spp. infection in sheep herds, blood samples and respective kidney and liver fragments were collected from 100 animals from twenty different properties during slaughter at a meat company in the Sorocaba region, São Paulo state, southeast Brazil. The microscopic agglutination test (MAT) was performed with 29 s

8. Immune responses to Leptospira infection: roles as biomarkers for disease severity
Various leptospiral components have been identified and shown to be involved in tissue destruction. In addition, immune responses to leptospires have been implicated in target organ damages in severe leptospirosis cases. Several inflammatory mediators were shown to be higher in susceptible animals than in resistant hosts. Moreover, cytokines/chemokines and s

9. Toxoplasmosis, leptospirosis and brucellosis in stray dogs housed at the shelter in Umuarama municipality, Paraná, Brazil
Background : Leptospirosis, toxoplasmosis and brucellosis are diseases with worldwide distribution. Among stray dogs, these zoonoses are facilitated by direct contact with other animal species, by the habit of scavenging garbage and hunting in search of food, drinking standing water, smelling other animals' urine, licking female genitalia and the sexual act

10. Prozone effects in microscopic agglutination tests for leptospirosis in the sera of mice infected with the pathogenic Leptospira interrogans serovar Canicola
Mice experimentally infected with a pathogenic strain of Leptospira interrogans serovar Canicola produced false negative results (prozone effect) in a microscopic agglutination test (MAT). This prozone effect occurred in several serum samples collected at different post-infection times, but it was more prominent in samples collected from seven-42 days post-i

11. Zoonoses in humans from small rural properties in Jataizinho, Parana, Brazil
The aim of this study was to conduct a serological survey for Lyme diseases, brucellosis, leptospirosis and toxoplasmosis and identify the risk variables related to these zoonoses in humans living in the rural area of Jataizinho, state of Parana, Brazil. A total of 63 rural properties were surveyed. Additionally, 207 serum samples collected from these rural

12. Investigação soroepidemiológica e molecular de brucelose e leptospirose em núcleos de conservação de gado curraleiro pé duro e pantaneiro / Seroepidemiological and molecular monitoring of brucellosis and leptospirosis in nucleus of in situ conservation of curraleiro pé-duro and pantaneiro breeds
As raças bovinas localmente adaptadas aos diferentes ecossistemas brasileiros caracterizam-se como uma alternativa para produção de alimentos, por apresentarem entre outras características, maior resistência a enfermidades. O objetivo geral foi avaliar a situação epidemiológica da brucelose e da leptospirose em núcleos de conservação de bovinos Cu
