MANUAL OF DETERMINATIVE BACTERIOLOGY 



Morphologically indistinguishable from 

 Treponema pallidum. 



Cultivable under anaerobic conditions 

 in the same medium used for Treponema 

 pallidum. 



Habitat : The cause of yaws — tropica 

 frambesia. Patients with the disease 

 give a positive Wassermann test. Prbo- 

 ably transmitted by contact. 



3. Treponema microdentium Noguchi. 

 (Jour. Exp. Med., 15, 1912, 81.) From 

 Greek viikros, small and Latin, teeth. 



The organism is less than 0.25 micron in 

 thickness in the middle and tapers toward 

 each extremity, which is pointed. The 

 length varies with age but may reach 8 

 microns and show an average of 14 curves. 

 Sometimes a long, thin flagella-like pro- 

 jection is observed at each extremity. 



Growth occurs under anaerobic condi- 

 tions in serum water medium containing 

 fresh tissue. The serum is slightly coag- 

 ulated and gives off a strong, fetid odor. 



Habitat : Normal oral cavity. 



4. Treponema mucosimi Noguchi. 

 (Jour. Exp. Med., 16, 1912, 194; Spiro- 

 chaeta mucosa Pettit, Contribution a 

 I'Etude des Spirochetides, Vanves, II, 

 1928, 190.) From Latin, mucous. 



Spirals: 0.25 to 0.3 by 8 to 12 microns. 

 The number of curves varies from 6 to 8. 

 Both extremities are sharply pointed and 

 often possess a minute curved projection, 

 8 to 10 microns long. 



Cultivable under anaerobic conditions, 

 forming mucin. 



The cultures give off a strong, putrid 

 odor. 



Takes the red in Giemsa's stain. 



Strict anaerobe. 



Source : From pus in a case of 

 pyorrhoea. 



Habitat : Found in pyorrhea alveolaris. 

 It possesses pyogenic properties. 



5. Treponema calligyrum Noguchi. 

 (Noguchi, Jour. Exp. Med., 17, 1913, 96; 

 Spirochaeta calligyra Zuelzer, 1925, in 

 Prowazek, Hand. d. path. Protoz., 3, 1931, 



1673.) From M. L., with beautiful 

 circles. 



Morphology: 0.35 to 0.4 by 6 to 14 mi- 

 crons, average 9 to 12 microns. Spirals 

 are regular and deep but more rounded 

 than those of Treponema pallidum. The 

 organism is of uniform width until near 

 the extremities which end in sharp points 

 with delicate projections. 



Motility : Active, chiefly rotating. 



Stains reddish-violet with Giemsa's 

 stain. 



Cultivation: Grows under anaerobic 

 conditions. 



Not pathogenic for monkeys or rabbits. 



Source: From smegma. 



Habitat : I^esions and membranes of the 

 pudenda. 



6. Treponema genitalis Noguchi. 

 {Treponema minutum Noguchi, Jour. 

 Exp. Med., 27, 1918, 671 ; not Treponema 

 minutum Dobell, Arch, f . Protistenk., 26, 

 1912, 151 ; not Treponema minutum 

 Castellani, 1916 ; Noguchi, Laboratory Di- 

 agnosis of Syphilis, New York, 1923, 260;

 1931, 1673; Spirochaeta genitalis Seguin 

 and Vinzent, Ann. Inst. Past., 61, 1938, 

 255.) From Latin, genital. 



Morphology: 0.25 to 0.3 by 3 to 14 mi- 

 crons. Spirals round, regular and shal- 

 low. Smaller than Treponema pallidum 

 and spirals are closer together. 



Motility: Active. 



Culture : Grows anaerobically and re- 

 quires fresh tissue. 



Non-pathogenic . 



Habitat: Found on mule and female 

 genitalia.
