Abstract
The G.I. tract extends from the mouth
or oropharyngeal area to the anus and, as
previously described, represents locations
of different body chemistry, muscle and
nervous control. Eye and nostril problems
share all their infections with the throat
and often the rest of the intestinal tract.
This is by virtue of the connecting naso
lachrymal duct and the cleft in the hard
plate in the roof of the mouth. All areas
may react to their bacteria, virus or fungus
infections by producing fluids, pussy discharges
or even hemorrhage. Some of the
micro-organisms exist as commensal, reproducing
on the surface of the tissue but
not penetrating or causing harm to the
host bird. Stress or other factors such as
a puncture or abrasion of the protective
covering of the mouth tissue give these
otherwise harmless organisms a chance to
invade and produce inflamation and a
disease.
