Infection with Chlamydiae, specifically Chlamydophila (Cp.) abortus, causes enzootic abortion in small ruminants. The disease is highly prevalent in most parts of the world and has a high economic impact especially on the sheep industry. Swine is another species that can suffer from chlamydial infection. Besides Cp. abortus, Cp. pecorum and Chlamydia (C.) suis can all cause reproductive failure...
Mice were intramuscularly immunized with a dnaK-encoding DNA plasmid. The protective effect of DNA immunization against Chlamydophila abortus infection was studied in pregnant and non-pregnant mice models. In non-pregnant mice, the dnaK vaccine induced a specific humoral response with the predominant IgG2a isotype, which failed to have in vitro neutralizing properties. No delayed-type hypersens...
In order to enhance the quantity and the protective properties of the antibodies induced by DNA vaccination with the heat shock protein dnaK gene of Chlamydophila abortus AB7 as well as to elicit an efficient cellular immune response, we vaccinated mice with a DNA prime followed by a boost with the recombinant DnaK protein. In non-pregnant mice, this strategy induced the same predominance of th...
BACKGROUND Prevention and control of ovine enzootic abortion (OEA) can be achieved by application of a live vaccine. In this study, five sheep flocks with different vaccination and infection status were serologically tested using a competitive enzyme-linked immunosorbent assay (cELISA) specific for Chlamydophila (Cp.) abortus over a two-year time period. RESULTS Sheep in Flock A with recent O...
