Abstract Background and Objective: Leptospirosis is a zoonosis infectious disease that is prevalent in tropical and subtropical regions and is caused by the pathogenic serovars of leptospires. Hence, we aimed at investigating the prevalence of antibodies against these bacteria in the blood samples of suspected leptospirosis. Material and Methods: the human serum samples (N = 130) were ...
Leptospirosis, caused by pathogenic species of Leptospira, is the most widespread zoonosis and has emerged as a major public health problem worldwide. The adhesion of pathogenic Leptospira to host cells, and to extracellular matrix (ECM) components, is likely to be necessary for the ability of leptospires to penetrate, disseminate and persist in mammalian host tissues. Previous work demonstrate...
BACKGROUND Leptospirosis is a worldwide zoonotic and recognized neglected infectious disease. It has been observed that only a proportion of individuals exposed to pathogenic species of Leptospira become infected and develop clinically evident disease. Moreover, little information is available in subsequent reinfections. In the present study, we determine if a first infection with leptospirosis...
Bovine semen experimentally contaminated with Leptospira santarosai serovar Guaricura was submitted to the modified EMJH medium with 5-fluorouracil (300mg/L) and nalidixic acid (20mg/L), named as "selective medium" and using the serial dilution technique, in order to evaluate the percentage of recovery of the added microorganism. The selective EMJH medium was found with higher percentage of rec...
Leptospirosis is a zoonotic disease of global importance with a mortality of up to 50% among patients requiring intensive care medicine. Meningitis or meningoencephalitis due to leptospires are considered to be an immunologically mediated disease and to occur mainly during the second phase of disease. Herein, we report a patient with severe meningo-encephalitis due to leptospirosis with evidenc...
BACKGROUND Pulmonary involvement in leptospirosis remains poorly recognized in regions where it is endemic, despite reports of recent outbreaks and epidemic disease. METHODS A prospective, population-based study was carried out to identify febrile patients exposed to Leptospira in urban and rural contexts in Iquitos, Peru. Evidence of exposure to Leptospira was obtained by serologic testing, ...
