PIBnet – Pasteur International Bioresources network
The PIBnet program aims at harmonizing microbial strain biobanking and analytical methods deployed within the microbiological expertise laboratories in Paris and throughout the International Network of Institut Pasteur. It is a large collaborative program […]
Expanding the toolbox for genetic manipulation of Leptospira spp.
In comparison to other bacterial species, genetics and molecular basis of the pathogenesis of leptospires are in their infancy. An improved understanding of leptospiral pathogenesis requires reliable genetic tools for functional genetic analysis of […]
Phenotypic characterization of transposon mutants in the pathogen L. interrogans
Site-directed homologous recombination has not been successful in pathogenic Leptospira and there exist only a few examples of mutants obtained by targeted mutagenesis. We have generated a library of random mutants in the pathogen […]
Cell morphology and motility in Leptospira spp.
Leptospira spp. are thin, highly motile, slow-growing spirochetes that can be distinguished from other bacteria on the basis of their unique helical shape and the presence of periplasmic flagella. We showed that peptidoglycan sacculi […]
Exoproteins and Leucin-Rich Repeat (LRR) proteins in Leptospira spp.
The roles of leptospiral exoproteins in the mechanisms of disease manifestation in the host have not been determined. We assessed the composition and quantity of exoproteins of pathogenic L. interrogans and their contribution to […]
Development and evaluation of rapid diagnostic tests on leptospirosis
Early laboratory diagnosis of leptospirosis is important to provide appropriate treatment of patients and to take rapid measures in case of an outbreak. Unfortunately, few tests possess both high sensitivity and specificity; this is […]
Molecular and serological investigations on leptospirosis
The genus Leptospira includes 35 Leptospira species, including L. mayottensis (see below), and more than 300 serovars have been described. Little is known about the circulating etiological agents of leptospirosis in most of the […]
