The research which has been described in the
thesis confirms that the agglutination test is the
most important factor in preventing pullorum disease.
By its regular and repeated use the incidence of the
disease can be quickly reduced and free flocks
established. The disease is perpetuated by the
continued existence of low -grade hatcheries; it would
seem possible to eradicate it by extending testing to
all breeding flocks.
The agglutination test is also of value in
preventing and controlling fowl typhoid, which despite
its increased incidence remains mainly a disease of
the poorer type of farm which constitutes a continuing
source of infection.
The use of modified living vaccines appears to
provide a promising means of prevention and
therapeutic treatment with furazolidone is useful
within the limitations which have been described.
