682 INDEX OF INFECTIOUS DISEASES. 



accompanied by arthritis and endocarditis, has led to the belief that 

 acute rheumatism is an infectious disease. All investigations here- 

 tofore made, however, have failed to demonstrate the causal relation 

 of the different bacilli and cocci isolated to the disease. 



Rhinitis Fibrinosa. Pseudomembranous rhinitis is often asso- 

 ciated with severe faucial diphtheria, and in these cases virulent 

 Klebs-Loffler bacilli, 349, are present. The primary form of the 

 affection, like conjunctivitis, usually runs a favorable course, and is 

 due usually to the attenuated diphtheria bacillus ; but here, too, 

 occasionally virulent diphtheria bacilli are found in the fibrinous 

 exudate. In such cases, of course, the nasal infection, however 

 mild, may give rise to severe faucial or nasal diphtheria in others. 

 In a few cases only pyogenic cocci have been found. 



Bihinosderoma. A localized infectious process due, apparently, 

 to the presence of the bacillus of rhinoscleroma. 



Rinderpest. The etiology of this acute exanthematous disease 

 in cattle is still obscure. Recovery from an attack, however, pro- 

 duces marked immunity, and Koch has achieved considerable 

 success in inoculating cattle against rinderpest 



Scarlet Fever. Streptococci are constantly present in large 

 numbers in the pseudomembranous exudate of scarlatinal angina, 

 484, and not infrequently also in the blood and organs after death 

 from scarlet fever. The presence of these streptococci in scarlet 

 fever is probably due to the great increase in the streptococci usually 

 existing in the throat secretions, and does not indicate any specific 

 causal relation to the disease. 



Septicaemia. General septicaemia in man is usually due to 

 infection by one or other of the common pyogenic cocci strepto- 

 coccus, 481, 483, pyogenes or staphylococcus, 469, aureus and albus. 

 Other micro-organisms which may sometimes be concerned in the 

 production of septicaemia are the pneurnococcus, 509, and colon ba- 

 cillus. Septicaemia in cattle, deer, swine, rabbits, and fowls is due 

 to infection by the bacillus of fowl-cholera or rabbit septicaemia 

 specifically, but various other bacteria produce septicaemia also in 

 rabbits, mice, swine, and fowls. 



Stomatitis. Schimmelbusch, Lingard, Foote and others have 

 described bacilli obtained by them from the necrotic tissues in cases 

 of noma, but the etiology of the disease is by no means established. 



Syphilis. The bacillus of Lustgarten, 309, is accepted by some 

 to be probably the specific cause of the disease, but this is far from 

 proven.
