The greater part of 145 typed Pasteurella haemolytica strains from calf could be attributed to Type A 1. Hence, in the context of virulence testing, this is the most important type at present for calf. Clearly manifest pneumonia was caused in calf by other strains of Types A 2, A 6, A 12, and T 10 which were also tested for their virulence parameters. The same applied to a number of strains which had so far been characterised merely as T or A/T strains.
