674 INDEX OF INFECTIOUS DISEASES. 



coli communis, 451, 453, was the only micro-organism present. 

 Streptococci and other varieties of bacteria from the intestines are 

 also occasionally found. 



Arthritis. The pneumococcus of Fraenkel, 509, has been fre- 

 quently fuund in arthritis following pneumonia. The gonococcus 

 of Neisser, 528, has been often met with in gonorrhceal arthritis. 

 Streptococci, 483, and staphylococci, 469, have been obtained from 

 the pus of the affected joints in suppurative arthritis following 

 scarlet fever. 



Beri-beri. Various species of bacteria have been found in the 

 blood and tissues of persons affected with beri-beri, but none of these 

 have been demonstrated to be the specific cause of the disease. 



Bronchitis. From the sputa of patients with putrid bronchitis 

 a spore-bearing bacillus has been obtained, the cultures of which 

 gave off the characteristic odor of fetid bronchitis. Hitzig (1895) 

 obtained two bacilli resembling the colon bacillus from a case of 

 putrid bronchitis. In ordinary acute bronchitis the pneumococcus 

 and streptococcus are most frequently found, but also small cocci like 

 the gonococci in shape, and occasionally other bacteria, especially 

 very small bacilli. In epidemics of influenza the influenza bacillus 

 is frequently found. 



Bronchopneumonia. The micro-organism most frequently met 

 with in bronchopneumonia is the pneumococcus of Fraenkel, 507, 

 508, 511 ; next to this the streptococcus, 483 ; then FriedKinder's 

 bacillus, 458, and the staphylococcus alone or in combination. 

 At times the influenza bacillus, 325, is often found also. In pneu- 

 monia complicating typhoid fever the typhoid bacillus may be 

 present in almost pure culture. 



Bubo. The pus from an unopened inguinal bubo following chan- 

 croid is usually sterile, though it may sometimes contain the ordinary 

 pus micrococci. 



Bubonic Plague. Due to the presence of the bacillus pestis of 

 Kitasato and Yersin, in the contents of the buboes and in the blood 

 of infected animals and man, 607. 



Carcinoma. No micro-organism has as yet been demonstrated 

 to bear any causal relation to cancer. Some attribute the disease to 

 protozoa. 



Cerebro -spinal Meningitis. The micro-organism most fre- 

 quently found in cerebro-spinal meningitis complicating other diseases 

 is the pneumococcus, 510, 511, of Fraenkel ; while in uncomplicated 

 epidemic pases the diplococcus intracellularis raeningitidis, 516, 519,
