Persistence of Arizona hinshawii in or on materials used in poultry houses.

The persistence of Arizona hinshawii on different materials which are used in poultry houses was studied. Arizona organisms remained viable on aluminium, plastic material of drinkers, rubber material of water hose, egg shell and in tap water and litter for 5, 11, 12, 9 and 19 weeks respectively after being contaminated and they persisted up to the last time of sampling, 25 weeks after contamination, in prepared poultry feed and on wood and carton material of egg trays.
