In the deeper layers of the agar medium white, mulberry-like colonies appear in the course of 3 or 4 days, which consist of long branched threads with club-shaped terminals, or of short rods and spore-like structures, easily stained after Gram in bouillon, granules as large as pin heads develop in the course of 4 to 6 days, the medium remaining perfectly clear. Milk is not coagulated although its reaction becomes distinctly acid. Pathogenicity. The intraperi- toneal administration of pure cultures in mice produces pus foci as large as peas on the peritonemn, â while sub- cutaneous inoculation of rabbits is followed by the development of nod- ules approaching the size of hazel- nuts, consisting- of a fatty or cal- careous substance surrounded hj fibrous tissues. Similar treatment of dogs is followed in the course of a few days by the development of firm Fig- 109. fUreptotiirix canis. nodules which subsequently disappear Pleurae exudate^ Fuchsln stain. or become converted into cold ab- scesses, the slimy, reddish-gray odorless pus of which contains streptothrix mj'celia. Guinea pigs, calves and monkeys resist experimental infection. In the brain of a dog that had died after several weeks of illness Trolldenier found numerous light grayish-white foci ranging in size to that of a pea, some of which contained purulent centers. One of the bronchial lymph glands was greatly enlarged and contained a slightly purulent substance in its interior. Mycelia similar to those described could be demonstrated in the cereb
