Folliculosis of Rabbits

Spontaneous conjunctival folliculosis, a disease widespread among rabbits, has been described in a preceding article (1) as occurring in two clinical forms, Type I and Type II . The former is characterized by a dormant chronicity with discrete lesions, whereas the second type, a more act ively progressive disease, presents an inf lammatory follicular reaction involving all the palpebral conjunctival surfaces. I t was found tha t the transit ion from one type to the other, an infrequent occurrence in nature, could more often be induced artificially by experimental procedures. From our studies a conclusion was drawn tha t the causal factor of the affection is not an ultramicroscopic virus bu t an infectious agent behaving after the manner of bacteria of low grade pathogenici ty. In this second paper the results of Our bacteriological investigations will be presented.
