Efficacy of vaccination of cattle with the Leptospira interrogans serovar hardjo type hardjoprajitno component of a pentavalent Leptospira bacterin against experimental challenge with Leptospira borgpetersenii serovar hardjo type hardjo-bovis.
OBJECTIVE To evaluate the efficacy of vaccination with the Leptospira interrogans serovar hardjo type hardjoprajitno component of a pentavalent Leptospira bacterin against a virulent experimental challenge with Leptospira borgpetersenii serovar hardjo type hardjo-bovis strain 203 in cattle. ANIMALS Fifty-five 6-month-old Holstein heifers. PROCEDURES Heifers that were negative for persistent...
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 کاملFunctional analysis of genes in the rfb locus of Leptospira borgpetersenii serovar Hardjo subtype Hardjobovis.
Lipopolysaccharide (LPS) is a key antigen in immunity to leptospirosis. Its biosynthesis requires enzymes for the biosynthesis and polymerization of nucleotide sugars and the transport through and attachment to the bacterial membrane. The genes encoding these functions are commonly clustered into loci; for Leptospira borgpetersenii serovar Hardjo subtype Hardjobovis, this locus, named rfb, span...
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...
