1890, 28) thought he found the same or- 

 ganism and described it as Gram-nega- 

 tive. Lehmann and Neumann (Bakt. 

 Diag., 1 Aufl., 2, 1896, 255) who studied 

 one of Zimmermann's cultures reported 

 this culture as Gram-positive and non- 

 motile, while the Franklands and Zim- 

 mermann speak of an active, circular 

 motility of the very slender rods. Leh- 

 mann and Neumann later (Bakt. Diag., 

 7 Aufl., 2, 1927, 710) list their Bacterium 

 nubilum (with other Gram-positive, non- 

 motile rods) as a possible Corynebacte- 

 rium. Jensen failed to find anything 

 that exactly corresponded to anj' of these 

 descriptions but describes a small, 

 Gram-jx)sitive, jxjorly-growing, pink to 

 red, slow gelatin-liquefying rod which he 

 says has little in common with corj^ne- 

 bacteria as a new variety Corynebacte- 

 rium nubilum var. nanum. Because the 

 earlj' cultures developed rhizoid growths 

 in stiff gelatin before liquefaction, Zim- 

 mermann originally planned to call this 

 species Bacillus nebulosus {loc. cit., 29), 

 a name that has been used by later au- 

 thors for several different organisms. 

 Attention should be called also to Bacil- 

 lus caudalus Wright, an organism which 

 Conn found to show occasional motility 

 (polar) and named Pseudomonas cauda- 

 datus. This common, slender, gelatin- 

 liquefying. Gram-negative, white to yel- 

 low chromogenic rod is much like the 

 Franklands' and Zimmermann's organ- 

 ism (see Conn, Xew York State Exp. 

 Sta. Tech. Bull. 67, 1919, 38). 



Corynebacterium paralyticans (Robert- 

 son) Ford. {Bacillus paralyticans Robert- 

 son, Rev. Neurol, and Psychiat., 

 Edinburgh, 1, 1903, 470; Ford, Textb. 

 of Bact., 1927, 281.) From cerebro- 

 spinal fluid. A diphtheroid. Thought 

 at one time to be the causal agent of 

 general paralysis. 



Corynebacterium parvum Prevot. 

 {Corynebacterium parvum infectiosum 

 Mayer, Cent. f. Bakt., I Abt., Grig., 98, 

 1926, 370; Prevot, Man. de Class, et 

 Determ. des Bact^ries Ana^robies, Mono- 



graphie, Inst. Past., Paris, 1940, 202.) 

 From blood in a post-natal fever. 



Corynebacterium periplanetae Bergey 

 et al. {Corynebacterium periplanetae 

 var. americana Glaser, Jour. Exp. Med., 

 51, 1930, 59; Bergey et al., Manual, 4th 

 ed., 1934, 550.) Found in the fat body 

 of the American cocki'oach {Periplaneta 

 americana). For a more complete de- 

 scription see Manual, 5th ed., 1939, 798. 



Corynebacterium plumosum (Fox) 

 Ford. {Mycobacterium- plumosum Fox, 

 Cent. f. Bakt., I Abt., Grig., 70, 1913, 

 148; Ford, Textb. Bact., 1927, 281.) 

 From blood of patient with chronic endo- 

 carditis. 



Corynebacterium pse udodiphtheriae 

 Eberson. (Jour. Inf. Dis., 23, 1918, 14.) 

 Hemoglobinophilic. From tonsils. 



Corynebacterium putidum Eberson. 

 ( Bacillus diphtheroides liquefaciens 

 Graham-Smith, Jour. Ilyg., 4, 1904, 258; 

 Eberson, Jour. Inf. Dis., 23, 1918, 16.) 

 From mouth. Cultures described bj^ 

 Graham-Smith liquefied gelatin and were 

 sluggishly motile. 



Corynebacterium pyogenes bovis (Roux) 

 Prevot. {Bacillus pyogenes bovis Roux, 

 Cent, f . Bakt., I Abt., Orig., 34, 1905, 541 ; 

 Eubacterium pyogenes bovis Prevot, Ann. 

 Inst. Past., 60, 1938, 295; Prevot, Man. 

 de Class, et Determ. des Bacteries Anaer- 

 obies, Monographie, Inst. Past., Paris, 

 1940, 204.) Common in bovine suppura- 

 tions. Said by Roux to be identical with 

 Bacillus pyogenes bovis Kunnemaun. 

 Prevot says it is probably identical with 

 the pyogenic Corynebacterium of Lucet. 

 See Corynebacterium pyogenes Eberson.

 rium renale {cuniculi) Manteufel and

 Past., 60, 1938, 304.) Gram- variable. 

 Forms gas in some media. From rabbit 

 kidneys.
