MUCOSUS CAPSULATUS GROUP 165 



carditis, and meningitis. The bacteria are found by blood 

 or sputum culture. Agglutination tests are not of value. 



Two other members of this group associated with disease 

 in man are Bacterium rhinoscleromatis and Bacterium ozenoe. 

 The former is said to cause a slow granulomatous inflamma- 

 tion on the nose, mouth, or larynx, in which hard nodular 

 swellings are formed, containing large typical cells loaded with 

 bacilli. Bacterium ozence is associated with fetid atrophic 

 rhinitis or nasal catarrh.

All the mucosus group are moderately pathogenic for 

 animals, but injections into these experimentally do not call 

 forth prototypes of the diseases in man. Usually a septi- 

 cemia with extensive fibrin deposit on serous membranes 

 results. The thick, stringy, or viscid character of the exu- 

 dates is peculiar to these bacteria. No antiserum has been 

 produced to use in cases of disease caused by them, but there 

 have been some favorable results after injecting dead organ- 

 isms during an attack.
