The latest update on the nationwide outbreak of contagious equine
metritis (CEM) that began about 5 months ago shows 18 stallions in 6
states and 5 mares in 3 states so far confirmed CEM-positive by the
USDA's National Veterinary Services Laboratories.

Besides the positive horses, the USDA's Animal and Plant Health
Inspection Service (APHIS) says locations have been confirmed for 797
other horses exposed to _Taylorella equigenitalis_, the bacterium
that causes the sexually transmitted disease that can cause sterility
and abortions if untreated.

The 820 total positive and exposed horses are in 48 states, with 171
exposed or positive stallions in 27 states and 649 exposed or
positive mares in 45 states.

Federal and state veterinary investigators continue to look for the
original source of the outbreak, 1st reported on a central Kentucky
premises in December 2008, but say no conclusions can yet be drawn.

Of the 171 stallions, 41 have completed the testing and treatment
regimen and been found negative, while 365 of the mares have
completed treatment.

An exposed horse is one that was bred to a positive horse, either
naturally or through artificial insemination, or one that is
epidemiologically linked to a positive horse by inspectors.
