Identification and characterization of the protein antigens of Leptospira interrogans serovar hardjo.
We radiolabeled Leptospira proteins with [35S]methionine. Solubilized extracts of radiolabeled L. interrogans serovar hardjo strain hardjoprajitno were analyzed by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis and fluorography. We compared the protein profile obtained in this manner to the protein profiles of various [35S]methionine-labeled Leptospira spp. The profil...
متن کاملDNA probe for detection of the Leptospira interrogans serovar hardjo genotype hardjo-bovis.
A DNA probe is described for the diagnostic and taxonomic identification of the North American cattle pathogen Leptospira interrogans genotype hardjo-bovis. The probe is specific for this genotype and does not hybridize to genomic DNA of any other leptospire pathogen commonly found in North America.
متن کاملRepetitive sequence element cloned from Leptospira interrogans serovar hardjo type hardjo-bovis provides a sensitive diagnostic probe for bovine leptospirosis.
A repetitive sequence element was cloned from the primary etiological agent causing bovine leptospirosis in North America, Leptospira interrogans serovar hardjo type hardjo-bovis. This element was used to design a sensitive diagnostic probe which distinguishes hardjo-bovis from other pathogenic leptospires which commonly infect domestic animals in North America and discriminates between hardjo-...
متن کاملMolecular typing of Leptospira interrogans serovar Hardjo isolates from leptospirosis outbreaks in Brazilian livestock
BACKGROUND Leptospirosis is caused by pathogenic spirochetes of the genus Leptospira spp. This zoonotic disease is distributed globally and affects domestic animals, including cattle. Leptospira interrogans serogroup Sejroe serovar Hardjo and Leptospira borgpetersenii serogroup Sejroe serovar Hardjo remain important species associated with this reproductive disease in livestock production. Prev...
متن کاملAddition of rabbit serum to EMJH medium improves isolation of Leptospira interrogans serovar hardjo.
The addition of 2% pooled rabbit serum to semi-solid commercial EMJH medium with EMJH enrichment and 0,5 mg of 5-fluorouracil per ml was found to enhance the growth rate and success of isolation of Leptospira interrogans serovar hardjo from bovine urine. Cultures made on media without serum had to be kept for more than 130 days before being discarded as negative.
