86 BACTERIOLOGY OF THE EYE 



I must further state that these cocci comparatively often show a 

 hsemolytic activity which, according to Max Neisser, is a peculiarity 

 of the pathogenic cocci. Further research is necessary on this 

 question. 1 



The following cocci should be considered identical with the Staphylococciis or 

 Micrococcus albus 2 (usually non-liquefaciens) : 



Coccus albus non-liquefaciens (Fick). 



Staphylococcus albus non-liquefaciens (Rymowicz). 



Staphylococcus cpidermidis albus (Morax, Griffith, Jackson, Lawson). 



[Staphylococcus habanensis (Santos-Fernandez) ?] . 



Micrococcus epidermidis albus (Randolph). 



Micrococcus albus non-liquefaciens (Fick). 



Staphylococcus brevis (Griffith), distinguished by the small size of the cocci. 



Diplococcus amplus (Gromakowski, Basso). 



Micrococcus candicans (Fick, Gombert, Marthen, Bernheim, Bach, Lachowicz, 

 Dudzinski, Basso, Eymowicz). 



Further, the greater proportion of the organisms called Staphylococcus pyogenes 

 albus by many authors, and the Trachoma cocci (Michel, Kucharsky, Sattler, 

 Goldschmidt, Staderini, Poncet, Petresco, Lawson), whose more exact 

 description agrees essentially with the Micrococcus albus. 



On account of the morphological similarity which these cocci, in secretion films, 

 can show to the Gonococcus, I have named them Gram-positive Pseudo-gonococci, 

 easily distinguishable by Gram's stain. This name is also used by Uhthoff, Brecht, 

 and others, with the same significance. The name does not signify that the organism 

 is a variety of the Gonococcus. At a later date I have used this name for the Gram- 

 negative Diplococci resembling Gonococci, naturally merely to signify that these 

 are morphologically similar Diplococci, which, however, cannot be considered as 

 Gonococci. 



Amongst the Gram-positive Pseudo-gonococci the Micr. albus and its allies take 

 the most important place ; it is exceedingly rare for pyogenic cocci to present this 

 double appearance so thoroughly as does the albus. 



The following occasional varieties are closely related, and, like the white cocci, 

 have a low pathogenic value : 



Staphylococcus cereus albus 3 (Santos, Fernandez, Basso). 

 Micrococcus cereus albus (Lachowicz). 3 

 Diplococcus albicans (Gromakowski). 

 Diplococcus albicans tardus (Basso). 

 Diplococcus albicans tardissimus* (Basso). 



1 Bossalino succeeded by passage through animals in exalting the virulence of an aureus, 

 which was low when obtained from the conjunctival sac of a rabbit operated for cataract. 

 Rupprecht has commenced a similar attempt with the common albus in my own laboratory, 

 and has sometimes had definite exaltation. 



2 In the lists by Brandt and Rosenthal, where the majority of the organisms here quoted 

 will be found, they are erroneously arranged as different species, some as pathogenic, others 

 as non-pathogenic. 



3 This variety, recorded by Passet, and characterized by a waxy gloss, thick growth, 

 slow development, and no liquefaction of gelatine, was considered as pyogenic by Giinther. 

 It is not so in the same sense as is aureus, and it is not pathogenic for animals. 



4 Abelsdorff' aud Neumann identify their Gram-negative Diplococci with this organism. 

 The single statement of Bumm that the Diplococcus tardissimus is Gram-negative, on 

 which Abelsdorff' and Neumann base their diagnosis, cannot, however, be allowed.
