0 an infectious disease of rabbits that usually kills them --
The 57 infected rabbits represented 20.7 % of the 275 rabbits sampled from sites where myxomatosis was found.
Rabbits on these sites had presumably experienced an epizootic of myxomatosis in the previous year.
The observation that only a small proportion of rabbits were seen with myxomatosis despite the serological evidence that most became infected was interesting.
The numbers indicate the order of discovery of cases of myxomatosis from which the released virus was obtained.
These trials confirmed that resistance to myxomatosis within wild rabbit populations continues to be substantial and that some rabbits are highly resistant.
Two inoculated rabbits did not show definite clinical signs and despite being housed with seven rabbits with severe myxomatosis did not develop disease.
Rabbits affected by myxomatosis were excluded from growth-curve fitting, since this disease causes loss of body condition.
Eight of ten rabbits in this group developed clinical signs of myxomatosis and these developed high levels of antibody by day 18.
