602 BACTERIA IN INFECTIOUS DISEASES. 



cus pyogenes albus was found in six, Staphylococcus pyogenes aureus 

 in two, Streptococcus pyogenes in three, Bacillus coli communis in 

 one, and various bacilli, vibrios, and cocci in the remaining cases; 

 some of these were fluorescent, some produced a foetid odor, etc. 



OZ^ENA. 



The researches of Thost, Klamann, Hajek, and others show that 

 Friedlander's bacillus is present in the nasal secretions in a consider- 

 able proportion of the cases of ozsena, but its etiological relation to 

 the morbid condition which gives rise to the offensive discharge has 

 not been established. 



Thost found this bacillus in twelve out of seventeen cases studied 

 by him, and frequently almost in a pure culture; but he also found 

 it in rhinitis from syphilitic ulceration, from polypus, and in simple 

 coryza. 



Hajek found Friedlander's bacillus in seven out of ten cases stud- 

 ied by him, but it was associated with various other species of bac- 

 teria, and especially with the pyogenic micrococci and with Bacillus 

 fluorescens liquefaciens. He also obtained almost constantly his 

 Bacillus fcetidus ozsense (No. Ill), which appears to have been the 

 cause of the foetid odor of the nasal discharge. 



Marsano (1890) in ten cases of ozsena found a capsule bacillus in 

 the nasal secretions which closely resembles Friedlander's bacillus, 

 but which he believes not to be identical with it. 



Abel (1893) in sixteen cases of " oza3na simplex " found a similar 

 capsule bacillus, but he arrives at the conclusion that it is not iden- 

 tical with Friedlander's bacillus, and believes it to be the specific 

 cause of rhinitis atrophicans fcetida. According to Abel his bacillus 

 resembles Pfeiffer's capsule bacillus^ (No. 80) more closely than it 

 does that of Friedlander, and it is almost identical with the capsule 

 bacillus of Fasching (No. 150). This bacillus is described by Abel 

 under the name of Bacillus mucosus Ozsena?. It is said to be differ- 

 entiated from the bacillus of rhinoscleroma and Bacillus sputigenus 

 crassus of Kreibohm, by the fact that it does not stain by Gram's 

 method. 



Strazza (1893) in twenty-five cases examined found a capsule 

 bacillus constantly associated with streptococci and staphylococci. 

 This bacillus was not found in cases of rhinitis chronica simplex or 

 of rhinitis syphilitica. According to Strazza, also, this bacillus is 

 differentiated from the bacillus of rhinoscleroma bj r the fact that it 

 does not stain by Gram's method ; it is said to resemble Pfeiffer's 

 bacillus in cultures, but to be somewhat smaller. 



Loewenberg (1894) has called attention to the fact that he re-
