Leptospira interrogans Binds to Cadherins

PLoS Neglected Tropical Diseases, 2014
Leptospirosis, caused by pathogenic species of Leptospira, is the most widespread zoonosis and has emerged as a major public health problem worldwide. The adhesion of pathogenic Leptospira to host cells, and to extracellular matrix (ECM) components, is likely to be necessary for the ability of leptospires to penetrate, disseminate and persist in ...

Transposon Sequencing in Leptospira interrogans

2020
Our limited understanding of the relationship of genotype to phenotype in the spirochete Leptospira interrogans stems from the inefficiency of the genetic tools available to manipulate the pathogen. The recent development of random transposon mutagenesis in L.

leptospira interrogans serovar hardjo vaccination against leptospira interrogans serovar balcanica infection

New Zealand Veterinary Journal, 1981
Abstract Extract Sir, — Leptospira interrogans serovar balcanica is now recognised as a widespread infection among opossums in New Zealand (2) and the possibility of domestic stock acting as accidental hosts has recently been demonstrated. (3) With the recent development of hardjo vaccines (1) (4) for controlling infection with this serovar in the ...

First evidence of glutathione metabolism in Leptospira interrogans

Free Radical Biology and Medicine, 2019
Glutathione (GSH) plays a role as a main antioxidant metabolite in all eukaryotes and many prokaryotes. Most of the organisms synthesize GSH by a pathway involving two enzymatic reactions, each one consuming one molecule of ATP. In a first step mediated by glutamate-cysteine ligase (GCL), the carboxylate of l-glutamic acid reacts with l-cysteine to ...

Leptospira interrogans serovar grippotyphosa infection in dogs

Journal of the American Veterinary Medical Association, 1996
Leptospirosis attributed to infection with serovar grippotyphosa was diagnosed in 11 dogs. In naturally and experimentally infected dogs, a stereotypic serologic response to infection with Leptospira serovar grippotyphosa was detected. Although the highest serum antibody titers developed against serovar grippotyphosa, most dogs also had lower titers ...

LEPTOSPIRA INTERROGANS SEROVAR HARDJO INFECTION OF CATTLE

Australian Veterinary Journal, 1979
A survey of normal cattle in the Southern Victorian statistical divisions revealed that microscopic agglutination titres to L. hardjo occur at high frequency and are distributed throughout the cattle population. These titres are difficult to interpret as they may represent recent or old exposure, with or without disease. L.

New host species for Leptospira borgpetersenii and Leptospira interrogans serovar Copenhageni

Veterinary Microbiology, 2018
We investigated the presence of infection by Leptospira spp. in an assembly of Sigmodontinae rodents from the Paraná Delta, Argentina. Rodents were captured in places with natural grassland, implanted forest, with and without raising cattle and in sites prone and not prone to flooding.

Nanofabricated versatile electrochemical sensor for Leptospira interrogans detection

Journal of Bioscience and Bioengineering, 2020
In this report, a LipL32 gene based nanofabricated electrochemical sensor for the detection of Leptospira interrogans has been developed using carboxylated multiwalled carbon nanotubes with gold nanoparticles (c-MWCNTs/nanoAu) electrode and graphene quantum dots (GQDs). The c-MWCNTs/nanoAu electrode was linked to GQDs using 4-aminothiophenol (ATP). The

Experimental Infection in Sheep with Leptospira Interrogans Serotype Hardjo

British Veterinary Journal, 1983
SUMMARY Twelve ewes (six pregnant) and two lambs were inoculated with Leptospira interrogans serotype hardjo, four lambs and one ram were kept as untreated controls. Pyrexia and antibody titres in all inoculated animals were consistent with infection. Leptospiraemia occurred in nine of the 14 inoculated animals. Clinical signs were so mild as to pass
