1. Tubercle bacilli when suspended in. distilled water, normal salt solution, bouillon and milk, are destroyed at 60° C. in 15 to 20 minutes. The larger number are destroyed in 5 to 10 minutes. 2. When tubercle bacilli are suspended in milk, the pellicle which forms during the exposure at 60° C. may contain living bacilli after 60 minutes.

Thermal Death Point

The thermal death point was determined in vitro for three isolates of Pseudomonas syringae pv actinidiae (Psa) A bacterial suspension was treated by placing in an Eppendorf tube then floating in a water bath at seven temperatures from 263 to 60C At each temperature an aliquot was removed after 5 15 35 75 155 315 and 635 min placed onto Kings medium B (KMB) in Petri plates and spread with a sterilised bent glass rod Petri plates were placed at 25C for 24 h and colonies counted There were three isolate replicates each in an Eppendorf tube per timetemperature combination There was no difference in response between isolate replicates but time and temperature differences were significant (P

Thermal Death Point

In summarising, the following points are to be noted:—1. The thermal death point of the blow-fly was definitely influenced by the factor of humidity.2. Saturated and dry air had the effect of lowering the thermal death point.3. Relative humidities from 60 per cent. to 80 per cent. were more favourable, while relative humidity of 70 per cent. actually was found to be an optimum point.4. From the weighings it may be concluded that death in saturated air was due to the inability of the flies to regulate their heat by evaporation.
