Characterization of the major antigens of Haemophilus equigenitalis (contagious equine metritis organism)

Nonimmune binding of equine immunoglobulin by the causative organism of contagious equine metritis, Taylorella equigenitalis.

This study identifies nonimmune binding of equine immunoglobulin by the causative organism of contagious equine metritis. Immunoglobulin binding to the bacterium was strongest for immunoglobulin G (IgG) and less for IgM; IgA was not bound. Binding of equine IgG was inhibited by human IgG, but not by IgG of domestic animals. Immunoglobulin binding by the bacterium appeared to be directed towards...

Treatment for Contagious Equine Metritis

Agglutinins to the causative organism of contagious equine metritis 1977 in human serum.

was recovered from the external genitalia of associated stallions which did not show any clinical signs of disease.’ A full description of the organism, which does not identify with any known bacterium, will be published elsewhere.2 Inoculation of a pure culture of the organism into the uterine cervix of healthy pony mares results in an identical clinical condition in 2-3 days.3 Powell4 has giv...

Energy metabolism of the contagious equine metritis bacterium.

The energy metabolism of the English E-CMO strain of contagious equine metritis bacterium was studied in whole cells and cell extracts. This bacterium appears to have an active Krebs cycle and probably obtains energy by oxidative phosphorylation since glycolysis and the hexose monophosphate pathways appear to be absent. These conclusions are based on the findings that [U-14C]glucose incorporati...

Contagious equine metritis in Portugal: A retrospective report of the first outbreak in the country and recent contagious equine metritis test results

Contagious equine metritis (CEM), a highly contagious bacterial venereal infection of equids, caused by Taylorella equigenitalis, is of major international concern, causing short-term infertility in mares. Portugal has a long tradition of horse breeding and exportation and until recently was considered CEM-free. However, in 2008, T. equigenitalis was isolated at our laboratory from a recently i...
