Survival of the bacterial turkey coryza agent

The survival of the turkey coryza agent was tested on wood, aluminium, glass, dust and faeces. Temperature of 10 degrees, 20 degrees, 30 degrees and 40 degrees C and relative humidities of 32, 58 and 78 per cent were chosen as test conditions. The survival of the turkey coryza agent was prolonged by low temperatures and low humidities. The only exception was wood, on which the bacteria showed the shortest survival periods, possibly because of intrinsic bactericides in the wood. In additional experiments the resistance of the agent was found to be greatest at about pH 7.
