Functional 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 کاملEfficacy 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 کاملIsolation and molecular characterization of Leptospira borgpetersenii serovar Hardjo strain Hardjobovis in the urine of naturally infected cattle in Brazil.
Most epidemiologic studies on bovine leptospirosis are based on serological tests that use antibodies against several serotypes, including the serovar Hardjo, which is widespread and considered to be the most adapted to bovine hosts. However, using only serological studies is not sufficient to identify and distinguish species of leptospires. The aim of this study was report the first isolation ...
متن کاملEffect of a monovalent vaccine against Leptospira borgpetersenii serovar Hardjo strain hardjobovis on fertility in Holstein dairy cattle.
OBJECTIVE To determine whether vaccination with a monovalent vaccine against Leptospira borgpetersenii serovar Hardjo strain hardjobovis would improve reproductive efficiency in Holstein cattle in a commercial dairy setting. DESIGN Randomized controlled trial. ANIMALS 1,894 Holstein cows and heifers from a Central California dairy. PROCEDURES Cattle were assigned to undergo SC administrat...
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.
