This disease is a very specific, contagious equids
disease which attacks mainly the young foals (6 to 24 months old).
This infection reaches the upper respiratory tract and is due to
a bacterium: Streptococcus equi.
This disease generally appears in the breeding where the sanitary
conditions are poor.
The disease is generally transmitted by respiratory tract after
direct contact with a sick equids or objects contaminated (drinking
The bacteria disease are fragile and can be easily eliminated by
disinfecting the material.
The donkey starts to present the first sign of the symptoms after
two weeks, loss of appetite, of form, moderated fever, slight cough,
bilateral nasal discharge, abscess formation especially under the
After a few days, the lymph nodes of the head and neck are swollen.
The recovery is approx 2-3 weeks without any important after-effects
for the animal. It is necessary to continue to isolate the animal
for several weeks after the recovery, because it can still constitute
a source of contamination for the other donkeys.
For the adults, the symptoms can be more discrete, but we can sometimes
observe certain complications like abscesses in the lungs, or in
the guttural pockets can be deadly.
|Prevention - Treatment
The contamination of the breed is generally due to
the introduction of a sick donkey. It is thus necessary to isolate
and supervise the new donkey for 2 to 3 weeks before putting it
in contact with the others donkeys.
In the event of infection, the environment of the donkey will have
to be disinfected (feeding troughs, buildings...) each day, and
all the stables (where the sick donkey was) have to be considered
as infected for a one month period.
The treatment with antibiotics is not always recommended during
the milder phase of the disease because they could disturb the installation
of immunity and would prevent a complete sterilization of the abscess.
That could then involve a chronic form.
