A Transmissible Tumor-like Condition in Rabbits

A tumor-like condition has been observed in a wild cottontail rabbit and has been found to be transmissible to both wild and domestic rabbits but not to guinea pigs, white rats, white mice, or chickens. The clinical picture of the experimentally produced condition and the pathological picture of the original and experimentally produced tumors have been described. The tumor has the general appearance of a fibroma. Methods used in transmitting the condition and satisfactory routes of inoculation have been described and discussed.
