2. Spirochetosis
The bacterium Borrelia anserina infects chickens,
turkey, geese, ducks, pheasants, grouse and
canaries with morbidity and mortality up to 100%. It
is transmitted by arthropods, e.g. Argas persicus,
and occasionally by infected faeces. The bacterium
is poorly resistant outside host but may be carried
by Argas persicus for 430 days. Brachyspira
pilosicoli, previously known as Serpulina pilosicoli, is
an intestinal spirochaete that can be associated with
inflammation of the large intestine in a broad range
of mammals and birds. It has been associated with
typhilitis, diarrhoea, reduced egg production, and
egg soiling in chickens.
