that it is due solely to mixed infections. Koch's 

 Theory is that it assumes a direct necrotizing action 

 on tuberculous nodules. Liebmann's Theory, that 

 it may be ascribed to increase in potency of the bacilli.

 Theory. Same as Liebmann's Theory. Rosen-

Tuberculoderma (tu-bur-ku-lo-dur'-mah). A cutane- 

 ous manifestation of the action of tubercle bacilli, a 

 tuberculocide. 



Tuberculofibroid (tu-bur-ku-lo-fi'-broid). Relating to 

 a tubercle that has undergone fibroid degeneration. 



Tuberculoma {Ju-ber-ku-lo'-mah). A tuberculous 

 tumor.

 tered watery solution of the protoplasm of moist living 

 bacilli, extracted by crushing with hydraulic pres- 

 sure.

Tuberculosis, i >ee Illus. Diet.) Cf. Acid, Tuber- 

 culinic. T., Arloing's and Courmont's Serum 

 Test in, glycerin peptone bouillon inoculated with 

 an old attenuated culture of the tubercle bacillus and 

 thoroughly agitated each day to insure homogeneity 

 of the culture finally develops a growth in which the 

 bacilli are uniformly disseminated and actively motile. 

 Blood-serum from the suspected case is mixed in small 

 test-tubes with the culture thus prepared, in propor- 

 tions of I to 5, I to io, I to 20, and the tubes inclined 

 at an angle of 45 degrees, being examined at intervals 

 of 2, 10, and 24 hours. A positive reaction is indi- 

 cated by a clarification of the mixture and the deposi- 

 tion of small flakes or granules in the bottom of the 

 tube, while microscopically it may be seen that the 

 bacilli are clumped and motionless. Reactions occur- 

 ring after the lapse of 24 hours are without clinical 

 significance. With normal serum in a dilution of I to 5 

 positive reactions do not occur, and they occur but 

 rarely with tuberculous serum in a dilution higher than 

 1 to 20. [DaCosta.] T., Arthritic, tubercle of joints.

 fall forward toward the abdominal wall. Kuestner's
