MANUAL OF DETERMINATIVE BACTERIOLOGY 



4. Corynebacterium tritici (Hutchin- 

 son) comb. nov. (Pseudomonas tritici 

 Hutchinson, India Dept. of Agr., Bact. 

 Ser., /, 1917, 174; Phytomonas tritici 

 Bergey et al., Manual, 3rd ed., 1930, 248; 

 Bacterium tritici Elliott, Bacterial Plant 

 Pathogens, 1930, 234.) From Latin triti- 

 cum, wheat; M. L., from the genus 

 Triticum,. 



Rods : .8 by 2 .4 to 3 .2 microns . Motile 

 with a polar flagellum. Gram-positive. 



Gelatin : No liquefaction. 



Agar colonies : Bright yellow becoming 

 orange, glistening, moist, margins entire. 

 Agar brownish. 



Broth: Turbid. Thin pellicle. 



Milk: Yellow surface and yellow pre- 

 cipitate. Little change. 



Nitrites produced from nitrates. 



No H2S produced. 



Acid but no gas from glucose and lac- 

 tose. 



This species is very similar to and may 

 be identical with Corynebacterium rathayi 

 Dowson. 



Source : From slimy heads of wheat in 

 India. 



Habitat: Pathogenic on wheat, Triti- 

 cum aestivum. 



* Appendix II : By the use of names 

 or by the descriptions given, authors 

 have indicated that the following are 

 related to the species placed in Coryne- 

 bacterium. Many are incompletely de- 

 scribed and may be identical with other 

 recognized species. 



Bacillus alcalifaciens Kurth. [Ba- 

 cillus pseudodiphtheriticiis alcalifaciens 

 Kurth, Ztschr. f. Hyg., 28, 1898, 429; 

 ibid., 431.) From patients suspected of 

 having diphtheria. 



Bacillus avium Migula. (Bacillus de 

 la diphth^rie aviaire, Loir and Ducloux, 

 Ann. Inst. Past., 8, 1894, 599; Bacillus 

 diphtheriae avium Kruse, in Fliigge, 

 Die Mikroorganismen, 2 Aufi., 2, 1896, 



410; Bacterium diphtheriae avium (sic) 

 Chester, Ann. Rept. Del. Col. Agr. 

 Exp. Sta., 9, 1897, 75; Migula, Syst. d. 

 Bakt., 2, 1900, 759.) Considered the 

 cause of a diphtheria-like disease of 

 birds in Tunis. Motile. Not now re- 

 garded as belonging in Corynebacterium 

 (Andrewes et al.. Diphtheria, London, 

 393). 



Bacillus clavatus Kruse and Pasquale. 

 (Kruse and Pasquale, Ztschr. f . Hyg., 16, 

 1894, 50 and 62; not Bacillus clavatus 

 Migula, Syst. d. Bakt., 2, 1900, 597.) 

 From the heart blood, kidney, etc., dur- 

 ing autopsy of a person who died with 

 liver abscesses following Egyptian 

 dysentery. This is a pseudodiptheroid 

 (Kruse, in Fliigge, Die Mikroorganismen, 

 3 Aufl., 2, 1896, 477) but is confused by 

 Eberson (Jour. Inf. Dis., 23, 1918, 5) 

 and Thomson and Thomson (Ann. Pickett 

 Thomson Res. Lab., 2, 1926, 65) with 

 anaerobic Bacillus No. Ill, a spore former 

 isolated by Fliigge (Ztschr. f. Hyg., 17, 

 1894, 290) from boiled milk and named 

 Bacillus clavatus by Migula {loc. cit.) 

 in 1900. 



Bacillus crassws Lipschtitz. (Lip- 

 schiitz, Bakt. Grundriss und Atlas der 

 Geschlechtekrankheiten, Leipzig, 1913, 

 64; Plocamobacterium crassum Lowi, 

 Wiener klin. Wchnschr., S3, 1920, 733; 

 not Plocamobacterium vaginae Lehmann, 

 in Lehmann and Neumann, Bakt. Diag., 

 7 Aufl., 2, 1927, 510.) This is the abun- 

 dant Gram-positive bacillus found in 

 ulcus vulvae acutum. It is the type 

 species (monotypy) of the genus Plo- 

 camobacterium Lowi (loc. cit.). Accord- 

 ing to Lowi this organism liquefies coagu- 

 lated blood serum and Lipschiitz (Cent, 

 f . Bakt., I Abt., Orig., S8, 1922, 5) reports 

 that, unlike lactobacilli, this organism 

 will grow on protein media without the 

 addition of sugar. Presumably therefore 

 it is not a lactobacillus and is not identi- 

 cal with Doederlein's bacillus as claimed
