188 IMPORTANT VARIETIES OF FISSION- FUNGI. 



quadrigeminus Klebs. It was very like the Micr. pyogenes albus. 

 (However, it liquefied solidified blood-serum, which the typical Micr. 

 pyogenes is said not to do; its color is reddish, but in this property is 

 variable, as is to be expected.) They have already retracted this 

 hardly probable suspicion (C. B. xxv, 546). 



Almost simultaneously Sanfelice and Malato (C. B. xxv, 641) have 

 reported that a coccus can be constantly cultivated from cases of variola, 

 which can not be differentiated morphologically from the Micr. a 

 aureus, but differs in its pathologic action from all other cultures of 

 Micr. pyogenes isolated by the authors. When injected into the cir- 

 culation, hyperemia of the skin and mucous membrane and sharply 

 outlined hemorrhages occur. 



Eegarding the much controverted "Cytoryctes variola? " Guar- 

 nieris, of the group of protozoa, consult the literature in Galli-Valerio, 

 Kritische Uebersicht uberden Zusammenhang der Variola in it Vaccine 

 (C. B. xxv, 380 and 424). 



Staphylococcus pemphigi neonatorum Almquist l 

 (Z. H.x). 



According to Strelitz (C. B. XIII, 107), the Micr. pyogenes is itself 

 the cause of pemphigus, and besides being cultivated from pemphigus 

 vesicles, is able to reproduce the condition. Others obtained similar 

 results ; for example, Bodenstab (compare Vogel) found that four chil- 

 dren cared for by the same midwife developed pemphigus within two 

 weeks (C. B. xxi, 288). 



Micrococcus biskra Heydenreich. 



(Cause of the Pende's ulcer, tropical ulcer, Delhi boil, Clou de 

 Biskra, etc.) 



According to the description of Heydenreich, it can not be differen- 

 tiated from the Micr. pyog. a aureus (C. B. v, 163). The statement 

 by Chantemesse (C. B. v, 221) that the gelatin is very slowly liquefied 

 also applies to many cultures of Micr. pyogenes. Chantemesse gives 

 as other points for 'differentiation from the Micr. pyogenes, its whitish 

 growth upon agar, and its luxuriant, rapid, watery and orange-red 



the surface in the gelatin stab as a faintly shining, waxy deposit with 

 a somewhat thick border. Both varieties are closely related to the 

 Micr. /? citreus and y albus. They often pass as forms of these, but 

 are differentiated, according to the insufficient description at hand, by 

 absence of liquefaction and slight or no pathogenic quality. 



Without being able to show this interpretation to be incorrect, we 

 refer to our note (p. 170) that the Micr. cereus albus was found by us 

 to be identical with the Micr. candicans Fliigge, with the exception 

 of its smaller size. We are not familiar with the Micr. cereus flavus; 

 it may perhaps belong to Micr. sulfureus Zimmermann. 



1 The Dipl. pemphigi acuti Demme, appears different. Is grown 

 only at incubator temperature (Cong. inn. Med. Wiesbaden, 1886).
