Leptospiral Pathogenomics

Leptospirosis, caused by pathogenic spirochetes belonging to the genus Leptospira, is a zoonosis with important impacts on human and animal health worldwide. Research on the mechanisms of Leptospira pathogenesis has been hindered due to slow growth of infectious strains, poor transformability, and a paucity of genetic tools. As a result of second generation sequencing technologies, there has be...

Leptospiral Uveitis.

Leptospirosis is widely regarded as the most widespread zoonosis in the world. Systemic leptospirosis is a biphasic illness. Ocular involvement in leptospirosis has been reported to be extremely variable, ranging from 2% to 90%. Ocular involvement is seen both in the systemic bacteraemic phase as well as in the immunological phase. Leptospiral uveitis is a common entity in the tropical countrie...

Leptospiral Colonial Morphology.

Stalheim, O. H. V. (University of Wisconsin, Madison) and J. B. Wilson. Leptospiral colonial morphology. J. Bacteriol. 86:482-489. 1963.-A sequence of apparent colonial types was observed with colonies of Leptospira pomona, L. canicola, L. icterohaemorrhagiae, and L. grippotyphosa in agar medium. Although some colonies of these serotypes had a different appearance initially, they eventually dev...

Characterization of the leptospiral outer membrane and description of three novel leptospiral membrane proteins.

The outer membrane (OM) of the mammalian pathogen Leptospira kirschneri was isolated in the form of membrane vesicles by alkaline plasmolysis and separated from the protoplasmic cylinder by sucrose density gradient ultracentrifugation. All four components of the alkaline plasmolysis buffer, including 1.0 M NaCl, 27% sucrose (wt/vol), 2 mM EDTA, and 10 mM Tris (pH 9), were required for efficient...
