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. 



Regarding the much controverted "Cytoryotes variolar" Guar- 

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

 Kritische Uebersicht uber den Zusammenhang der Variola mit Vaccine 

 (C. B. xxv, 380 and 434). 



Staphylococcus pemphigi neonatorum Almquist ^ 

 (Z. H. X). 



According to Strelitz (C. B. siii, 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, 28" 



Micrococcus biskra Heydenreich. 



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

 Biskra, etc.) 



According to the description of He.vdenreich, it can not be diSeren- 

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

 by Chantemesse (C. B. v, 231) that the gelatin is very slowly liquefied 

 also applies to many cultures of Jlier. 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. /? oitreus and >■ albus. They often pass as forms of these, but 

 are differentiated, according to the insuiificient 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 foimd by us 

 to be identical with the Micr. candioans FHigge, with the exception 

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

 it may perhaps belong to Jlicr. sulfureus Zimmermann. 



' The Dipl. pemphigi acuti Demnie, appears different. Is grown 

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