== Introduction ==

== Introduction ==

Avian spirochaetosis affects a number of avian species including chickens, turkeys, pheasants, ducks and geese&nbsp;as well as&nbsp;game&nbsp;birds.&nbsp;It is spread transovarially and trans-stadially,&nbsp;by soft'''ticks '''of the ''Argas'' (fowl&nbsp;ticks)&nbsp;family, but direct transmission&nbsp;via the faeco-oral route also occurs. The organism has been found to survive for up to two months in droppings, but is susceptable to disinfectants. Direct transmission of the disease can also occur through cannibalism, scavenging on infected carcasses or multiple use of needles and syringes by the stock men. <br>Outbreaks of the disease tend to occur during peak tick activity during warm, humid conditions.

There is no specificity of the disease&nbsp;for any&nbsp;age of chickens, with all being susceptable. '''Free-range''' or chickens living on litter bedding are more susceptable to the disease than battery hens. The disease is also less prevelent in broiler chickens due to the 'all in all out' system in these cases. Exotic breeds will sucumb to the disease more readily than native birds.
