LfhA, a novel factor H-binding protein of Leptospira interrogans.
The early phase of leptospiral infection is characterized by the presence of live organisms in the blood. Pathogenic Leptospira interrogans is resistant to the alternative pathway of complement mediated-killing, while nonpathogenic members of the genus are not. Consistent with that observation, only pathogenic leptospires bound factor H, a host fluid-phase regulator of the alternative complemen...
متن کاملPenicillin-binding proteins in Leptospira interrogans.
The Leptospira interrogans ponA and pbpB genes were isolated and characterized. ponA and pbpB encode the penicillin-binding proteins (PBPs) 1 and 3, respectively. There is little sequence variation between the PBP genes from two L. interrogans strains (serovar icterohaemorrhagiae strain Verdun and serovar pomona strain RZ11). The deduced L. interrogans PBP 1 and PBP 3 protein sequences from the...
متن کاملIdentification of Cell-Binding Adhesins of Leptospira interrogans
Leptospirosis is a globally distributed bacterial infectious disease caused by pathogenic members of the genus Leptospira. Infection can lead to illness ranging from mild and non-specific to severe, with jaundice, kidney and liver dysfunction, and widespread endothelial damage. The adhesion of pathogenic Leptospira species (spp.), the causative agent of leptospirosis, to host tissue components ...
متن کاملcloning, expression and purification of the factor h binding protein and its interaction with factor h
background and objective: neisseria meningitidis is a leading cause of meningitis and sepsis worldwide. the factor h binding protein (fhbp) is a key virulence factor of neisseria meningitidis that is able to selectively bind to human factor h, the key regulator of the alternative complement pathway, which it has important implications for meningococcal pathogene- sis and vaccine design. the aim...
متن کاملIn Vitro Identification of Novel Plasminogen-Binding Receptors of the Pathogen Leptospira interrogans
BACKGROUND Leptospirosis is a multisystem disease caused by pathogenic strains of the genus Leptospira. We have reported that Leptospira are able to bind plasminogen (PLG), to generate active plasmin in the presence of activator, and to degrade purified extracellular matrix fibronectin. METHODOLOGY/PRINCIPAL FINDINGS We have now cloned, expressed and purified 14 leptospiral recombinant protei...
