Leptospira biflexa antigen (strain Patoc 1) is a non-pathogenic organism, which can be used as a prototype antigen for the development and manufacturing of diagnostics reagents such as ELISA. L. biflexa is cultivated in broth culture and after harvest extracted by ethanol. The antigen is suitable for the detection of IgM and IgG antibodies against. Abstract. Bacterial specific primers were used to amplify 23S rRNA genes from a representative strain from each of the 23 serogroups of the pathogenic Leptospira interrogans and 8 strains from 6 serogroups of the non-pathogenic Leptospira biflexa.Only regions of extreme variability, which had been identified on the basis of homology-based search of all the 23S rRNA sequences available in.
Leptospira interrogans is a spirochaete responsible for a zoonotic disease known as leptospirosis. Leptospires are able to penetrate the abraded skin and mucous membranes and rapidly disseminate to target organs such as the liver, lungs and kidneys. How this pathogen escape from innate immune cells expression of LigA and LigB in L. biflexa confers enhanced adhesion to cell culture and fibronectin. This study indicates that L. biflexa can serve as a surrogate host to characterize the role of virulence factors in Leptospira sp. .These results contribute to a better understanding of the pathogenesis of leptospirosis and may be important i The saprophyte Leptospira biflexa is an excellent model for studying the physiology of the medically important Leptospira genus, the pathogenic members of which are more recalcitrant to genetic manipulation and have significantly slower in vitro growth. However, relatively little is known regarding Leptospira biflexa is a free-living saprophytic spirochete present in aquatic environments. We determined the genome sequence of L. biflexa, making it the first saprophytic Leptospira to be sequenced. The L. biflexa genome has 3,590 protein-coding genes distributed across three circular replicons: the major 3,604 chromosome, a smaller 278-kb replicon that also carries essential genes, and a.

Saint Girons I, Bourhy P, Ottone C, Picardeau M, Yelton D, Hendrix R, Glaser, P, Charon N. The LE1 bacteriophage replicates as a plasmid within Leptospira biflexa: construction of an L. biflexa - Escherichia coli shuttle vector. Journal of Bacteriology 2000;182:5700-5705 The most apparent difference between the two types of Leptospira bacteria is the density of LPS, or lipopolysaccharide, in the cell. Compared to L. biflexa, L. interrogans had considerably more LPS, suggesting the LPS plays a role in virulence. Genomically, the saprophytic species were found to contain a third replicon, containing genes coding.
. Dělení leptospiróz je velmi komplikované. Tradičně se dělí na patogenní druhy (Leptospira interrogans) a na nepatogenní druhy (Leptospira biflexa).

The genus Leptospira belongs to the order Spirochaetales and is composed of both saprophytic and pathogenic members, such as Leptospira biflexa and L. interrogans, respectively. A major factor contributing to our ignorance of spirochetal biology has been the lack of methods available for genetic analysis of these organisms. In recent years, an E. coli-L. biflexa shuttle vector has been. Movement of leptospires (A, from Goldstein and Charon, 1988) and electronic microscopy of Leptospira biflexa (B). During translational motility, counterclockwise rotation of the perisplasmic flagellum produces spiral-shaped ends at the leading edge while concomitantly, clockwise PF rotation causes gyrating cell ends at the tail to remain hooked. The genus Leptospira was previously divided into two species, Leptospira interrogans and Leptospira biflexa, which were differentiated by a number of biochemical tests (9, 10, 15). Most reports of human infection are based on this phenotypic classification system, and L. interrogans comprised all pathogenic strains, while L. biflexa was thought. Background and Aim. Leptospira , the causal agent of leptospirosis, has been isolated from the environment, patients, and wide spectrum of animals in Russia. However, the genetic diversity of Leptospira in natural and anthropurgic foci was not clearly defined. Methods .
