A comparison of skin lesions produced in calves by three strains of the virus (Allerton BA, bovine mammilitis and 69/1LO) showed that Allerton BA was less pathogenic for calves than the other two strains. Very few inclusion bodies were found in the lesions produced by Allerton BA, and the maximum titre of virus in the lesions was lower than the titres obtained with bovine mammillitis and 69/1LO. Moreover the thickness and diameter of the lesions with Allerton BA were less than those with the other strains. It is speculated that Allerton BA strain, which originated from a buffalo, might behave similarly to bovine mammillitis and 69/1LO after serial passages in cattle.
