Abstract
Two groups of cattle, one ECF-susceptible: and the other ECF-recovered, were given East Coast Aver challenges. The challenge was given either as a Classical tick challenge or by inoculation of a stability derived from the same batch of ticks. All Susceptible animals died from both methods of challenge, with consistently uniform reactions in each case. Animals recovered from ECF consistently withstood challenge. Two reasons are given for preferring a stabilize challenge to a classical 1O-tick challenge, namely reproductability of Forbid lethal challenge over an extended period and the for less strict confinement the challenged animals.
