The aim of the study was to evaluate the prevalence of antibodies specific to different serogroups of Leptospira sp. in swine populations in Poland. The serological survey was conducted in 2006. A total of 7 252 swine serum samples coming from all provinces of the country were investigated. The samples were examined by the use of a microscopic agglutination test. As antigens, six Leptospira ser...

Over a period of five years (2005–2010) a total of 358 red fox (Vulpes vulpes) serum samples were collected during regular hunting procedures, mostly in the continental part of Croatia. All samples were tested using the microscopic agglutination test (MAT) for the presence of specific antibodies (Ab) to 12 Leptospira spp. pathogenic serovars. Specific antibodies for 11 different Leptospira spp....

The California sea lion ( Zalophus californianus ), a permanent inhabitant of the Gulf of California in Mexico, is susceptible to pathogenic Leptospira spp. infection, which can result in hepatic and renal damage and may lead to renal failure and death. During summer 2013, we used the microscopic agglutination test (MAT) to investigate the prevalence of anti-Leptospira antibodies in blood of cl...

In order to investigate the seroprevalence of leptospirosis in traditional dairy farms, a serological study was conducted in Gilan province. For this study,, a total of 205 serum samples were randomly collected from nine districts of this province. All serum samples were serologically tested by the standard MAT using live antigens representing the following Leptospira interrogans serovars: Grip...

INTRODUCTION Leptospirosis, caused by infection with pathogenic Leptospira species, is one of the most prevalent zoonotic diseases in the world. Current leptospiral vaccines are mainly multivalent dead whole-cell mixtures made of several local dominant serovars. Therefore, design and construction of an efficient recombinant vaccine for leptospirosis control is very important. OmpL1 is an immuno...

It is well known that Leptospira vaccine prevents the disease. However specificity for serovars limits the efficacy of killed whole cell vaccines. Leptospiral antigens that induce cross-protective immunity to the various serovars are sought as new vaccine candidates. In this paper, we have summarized both past and current findings about leptospiral antigens that are conserved among pathogenic l...

Changes in the formulation of the Leptospira components of dog vaccines are being considered in Europe, following changes in North America. This article discusses the options for change and recommends the continued inclusion of serovars Icterohaemorrhagiae and Canicola plus the inclusion of serovars Bratislava and Grippotyphosa (for mainland Europe only). If other serovars, such as Pomona, are ...

OBJECTIVE To determine the seroprevalence of Leptospira and the serovars responsible for Leptospira exposure in rats in Grenada in order to assess rats as a reservoir host for human infection. DESIGN AND METHODS Rattus norvegicus rodents were collected from each of the six parishes on the island of Grenada. Serum from 237 rats was tested by the microscopic agglutination test (MAT) and an Immu...

Leptospirosis, a zoonotic disease that is caused by many serovars which are more than 200 in the world, is an emerging worldwide disease. Accurate and rapid diagnostic tests for leptospirosis are a critical step to diagnose the disease. There are some commercial kits available for diagnosis of leptospirosis, but the obscurity of a species- or genus-specific antigen of pathogenic Leptospira inte...

From 2002 to 2005, we collected 118 serum samples from 34 species belonging to 13 families of zoo animals in Korea and determined the prevalence of antibodies for 18 serovars of Leptospira spp. using the microscopic agglutination test (MAT). Twenty-nine (25%) of the serum samples tested were positive for one or more of the serovars. There were no significant differences in relation to genders: ...
