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 ...

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.

NOTES: Leptospira interrogans Serovar Unipertama Isolated in Malaysia

International Journal of Systematic Bacteriology, 1990
A leptospiral isolate from a bovine kidney was found to be antigenically different from all previously recognized serovars of Leptospira interrogans based on the cross-agglutinin absorption test. The new serovar belongs to the Sejroe serogroup, and the name Leptospira interrogans serovar unipertama is proposed for it, with strain K2-1 as the reference ...

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.

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

Leptospira interrogans serovar bratislava infection in two dogs

Journal of the American Veterinary Medical Association, 1991
Two dogs with clinical histories suggestive of leptospirosis were examined serologically and culturally for evidence of leptospiral infection. Antibodies to Leptospira interrogans serovar bratislava were detected in serum from one dog, and the organism was isolated from urine of that dog.

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 requires heme oxygenase for disease pathogenesis

Microbes and Infection, 2009
We recently characterised the Leptospira interrogans heme oxygenase (hemO) gene and showed that HemO was required for growth with hemoglobin as the sole iron source. Here we investigated the role of HemO in pathogenesis. Hamsters inoculated with the hemO mutant showed 83% survival, compared with 33% for a control mutant (intergenic transposon insertion)

Leptospira interrogans in Rodents from Cape Verde

Vector-Borne and Zoonotic Diseases, 2016
Leptospirosis is an important worldwide zoonotic disease that can infect both animals and humans. In most cases, leptospirosis is a nonspecific self-limiting illness, but some patients can develop a severe form with a high mortality. This study was carried out in Santiago Island, Cape Verde, in 2012-2013.

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
