leptospirosis is one of the main causes of acute febrile illness and is presumed to be the most widespread zoonotic disease in the world. cattle populations may be infected with serovars hardjo, pomona and grippotyphosa. infection with icterohaemorrhagiae, bratislava, hebdomadis, autumnalis, australis, sejroe, canicola and bataviae serovars also occurs. in this study, 200 serum samples were col...

INTRODUCTION leptospirosis is a zoonosis of worldwide importance. The disease is endemic in Brazil. This study was conducted to describe the clinical and laboratory presentation of leptospirosis in a metropolitan city of Brazil. METHODS this is a retrospective study including 201 consecutive patients with leptospirosis admitted to tertiary hospitals in Fortaleza, Brazil, between 1985 and 2006...

BACKGROUND Leptospirosis is an emerging infectious disease. The differential diagnosis of leptospirosis is difficult due to the varied and often "flu like" symptoms which may result in a missed or delayed diagnosis. There are over 230 known serovars in the genus Leptospira. Confirmatory serological diagnosis of leptospirosis is usually made using the microscopic agglutination test (MAT) which r...

Background Leptospirosis is an emergent zoonotic disease caused by pathogenic Leptospira spp., and humans are regarded as an accidental or dead-end host [1]. The global incidence of severe human leptospirosis was estimated to be approximately 500.000 cases worldwide, although this is likely an underestimate due to the lack of a reliable diagnostic test. Mortality ranges from 10 to > 50% for Wei...

The epidemiologic status of leptospirosis in Egypt has not been well defined because of difficulties in disease diagnosis. A retrospective study was conducted to detect leptospiral antibodies among undiagnosed acute febrile illness (AFI) and hepatitis cases. Approximately 16% of both AFI (141/886) and acute hepatitis (63/392) cases showed seroreactivity to Leptospira IgM by ELISA and microscopi...

A survey was conducted to identify reservoirs for urban leptospirosis in the city of Salvador, Brazil. Sampling protocols were performed in the vicinity of households of severe leptospirosis cases identified during active hospital-based surveillance. Among a total of 142 captured Rattus norvegicus (Norwegian brown rat), 80.3% had a positive culture isolate from urine or kidney specimens and 68....

Introduction: Leptospirosis is a zoonotic infection affecting humans. The main sources of are animal reservoir hosts and man the accidental host in disease transmission process. diagnosis usually made by microscopy, culture, molecular techniques, serological tests like ELISA, MAT (Microscopic Agglutination Test) MSAT (Macroscopic Slide Test). ELISA method to detect IgM antibodies used as good c...

In a prospective study in Barbados between 1979 and 1989, 321 cases were diagnosed in 638 patients presenting at a hospital with symptoms of leptospirosis. Initial diagnosis was based on patient history and characteristic signs and symptoms. In 92 cases (29%), diagnosis was confirmed by isolation of organisms from the blood, urine, or dialysate fluid; in the remaining 229 cases (71%) diagnosis ...

Leptospirosis is not commonly reported from the Salem district in central Tamil Nadu in India. In October 2000, a rice mill worker, who had fever and jaundice, tested positive in leptospiral IgM enzyme-linked immunosorbent assay (ELISA). Microbiological and serological investigations were performed on the patient, a sample population of the rice mill workers, and the animal and rodent populatio...

Abstract Leptospirosis is an important zoonotic bacterial disease caused by Leptospira spp. Earlier studies from North Khorasan province (Iran) reported the presence of in wild canines and rodents. To date, there no data on seroprevalence leptospirosis among humans this province. This study was performed to determine prevalence human leptospiral infection people with different occupations. The ...
