MANUAL OF DETERMINATIVE BACTERIOLOGY 



concluded that they were due to con- 

 taminating organisms (Ford, Textb. of 

 Bact., 1927, 360). From water. 



Spirillum sporiferum Migula. (Syst. 

 d. Bakt., 2, 1900, 1028.) Produces 

 spores. The spirals in which the spore 

 formation is beginning are like Spirillum 

 leucomelaenum Perty (Ford, loc. cit., 

 336). Giesberger (loc. cit., p. 60) places 

 this and other so-called spore-forming 

 spirilla in Sporospirillum Orla-Jensen 

 (Cent. f. Bakt., II Abt., 23, 1909, 340). 

 From a bean infusion. 



Spirillum sputigenum Miller. (Die 

 Mikroorganismen der Mundhohle. Leip- 

 zig, 1892; Deutsche med. Wchnschr., 33, 

 1906, 1 and 348. ) Hoffman and Prowazek 

 (Cent. f. Bakt., I Abt., Orig., 4i, 1906, 

 741) claim that Spirillum sputigenum 

 hasperitrichousflagella. Giesberger {loc. 

 cit., 63) places this in Selenomonas 

 Prowazek (Cent. f. Bakt., I Abt., Orig., 

 70, 1913, 36). Muhlens (Cent. f. Bakt., 

 I Abt., Orig., 48, 1909, 525) reports 1 to 

 3 flagella, the majority of the organisms 

 having apparently a single thick fiagellum 

 (a bunch of flagella) on the concave side 

 (Ford, Zoc. cz7., 367). Anaerobic. From 

 the buccal cavity. 



Spirillum slomachi Lehmann and Neu- 

 mann. {Spirillum Form a, 13, y, 5 

 Salomon, Cent. f. Bakt., I Abt., 19, 1896, 

 433; Lehmann and Neumann, Bakt. 

 Diag., 2 Aufl., 2, 1899, 362.) Found in 

 stomach of dog, cat and rat. 



Paraspirillum vejdovskiiDoheW. (Arch, 

 f. Protistenk., 24, 1911, 97.) Found only 



once in fresh water containing Oscilla- 

 toria. Flagellate flexible spiral cells 

 described as possessing a nucleus. This 

 may be a protozoan. 



SpirohaciUus gigas Certes. (Bull. Soc. 

 Zool. France, 14, 1889, 322; abst. in Ann. 

 de Microgr., 2, 1889-1890, 137.) From 

 water. 



Vibriothrix tonsillaris Tunnicliff and 

 Jackson. (Organism from Actinomyces- 

 like granules, Tunnicliff, Jour. Inf. Dis., 

 38, 1926, 366; Tunnicliff and Jackson, 

 ibid., 46, 1930, 12.) From tonsillar 

 granules. May be identical with Lepto- 

 thrix asteroide Mendel and as a Gram- 

 negative, anaerobe may belong in Bac- 

 teroides according to Rosebuiy (Bact. 

 Rev., 8, 1944, 202). 



Vibriothrix zeylanica (Castellani) Cas- 

 tellani. {Spirillum zeylanicum Castel- 

 lani Jour. Ceylon Branch Brit. Med. 

 Assoc, 7, 1910, 5 and Philipp. Jour. 

 Sci., 5, No. 2, Sect. B., Medical Sciences, 

 July, 1910; Vibrio zeylanicus Castellani, 

 1913, Bacillus zeylanicus Castellani, 

 1913 and Vibriothrix zeylanica Castellani, 

 1917, quoted from Castellani and Chal- 

 mers, Man. Trop. Med., 3rd ed., 1919, 

 1069; Spirobacillus zeylanicus Castellani, 

 Spagnuolo and Russo, Bull. Soc. Path. 

 Exot., 11, 1918, 271.) Motile. Gram- 

 negative. From cases of dysenteric 

 enteritis in Ceylon. This is the type 

 species of the genus Vibriothrix Castel- 

 lani (see Castellani and Chalmers, loc. 

 cit., 1068).
