OBJECTIVE To obtain up-to-date data on the prevalence of antibodies to Leptospira serovars in central Queensland beef herds preliminary to assessing their role in bovine subfertility and the role of cattle as a zoonotic reservoir. DESIGN Sera from 2857 female cattle in 68 central Queensland beef herds were tested for antibodies to 14 Leptospira serovars using the microscopic agglutination tes...

In the recent years, the wild boar (Sus scrofa) trade has increased in Brazil. The present study aimed to detect Leptospira spp. infection in 308 blood samples from wild boars bred in São Paulo state, Brazil. The microscopic agglutination test (MAT) was performed using 29 serovars. Sixty three (63; 20.45%) animals tested positive against the serovars Hardjo (29/63; 46.0%), Copenhageni (11/63; 1...

Fingerprints for 72 reference serovar strains of pathogenic Leptospira spp. were obtained by pulsed-field gel electrophoresis (PFGE) following NotI restriction digests of the chromosome. These strains included the serovar reference strains of serogroups Australis, Ballum, Bataviae, Grippotyphosa, Panama, Pomona, and Pyrogenes. Sixty-four serovars could be identified by a unique NotI restriction...

A serologic survey was conducted among 76 sows randomly selected from a single farrow-to-finish swine herd, located on the Ibiúna municipality, state of São Paulo, Brazil, to investigate associations between Leptospira spp. seropositivity and reproductive performance. For detection of anti-leptospires antibodies, the microscopic agglutination test (MAT) was carried out using live cultures of 22...

BACKGROUND Dairy cattle were used as sentinels for the presence of Leptospira infection in Swedish livestock in four regions contrasting in precipitation and temperature during the summer time. The aim of the study was to estimate the prevalence of five serovars of Leptospira of low pathogenicity in dairy cattle in these four regions. FINDINGS Around 150 blood samples were collected from five...

OBJECTIVE To determine the seroprevalence of antibodies against Leptospira serovars among veterinarians and identify risk factors for seropositivity in veterinary care settings. DESIGN Seroepidemiologic survey. STUDY POPULATION Veterinarians attending the 2006 AVMA Annual Convention. PROCEDURES Blood samples were collected from 511 veterinarians, and serum was harvested for a microcapsule...

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. Leptospira is the aetiological agent of leptospirosis, a bacterial zoonosis with worldwide distribution. There are over 230 known serovars in the genus Leptospira. The true prevalence of lepto...

Leptospirosis is the most widespread zoonosis in the world and significant efforts have been made to determine and classify pathogenic Leptospira strains. This zoonosis is maintained in nature through chronic renal infections of carrier animals, with rodents and other small mammals serving as the most important reservoirs. Additionally, domestic animals, such as livestock and dogs, are signific...

leptospirosis is one of the zoonotic diseases caused by different serovars of the species leptospira interrogans .  the source of infection in humans is usually either direct or indirect contact with the urine of infected animals.  in this study, 400 human blood samples collected from tribal areas of farsan and koohrang cities in west centeral iran.  the serum samples were analyzed employing mi...

background leptospirosis is an important zoonotic disease caused by pathogenic leptospira which can infect both humans and animals. this disease is caused by various serovars of leptospira interrogans sensu lato infection. rats are known to be one of the most important reservoirs and transmission sources of leptospirosis. however, the status of leptospirosis in wild rats has been unknown in man...
