Large numbers are found in fresh tubercles;few are found in chronic articular, osseous or glandular foci, andinoculations may be necessary to demonstrate the nature of long-standing lesions. Arloing and Courmont found that serum from inoculatedrabbits or goats, agglutinized tubercle bacilli in a dilution of 1 to 5 or20, in two to twenty-four hours; agglutination was noted in 95 per cent,of the cases of lung tuberculosis and in 50 per cent, of the cases of surgicaltuberculosis. Associated or Mixed Injection.—Symbiosis has been noted with thestreptococcus, staphylococcus and pneumococcus, to a lesser degreewith the Bacillus pyocyaneus, influenza, etc. (v. i.)
