100 RESEARCH IN PROTOZOOLOGY 



a forced feeding by means of a stomach tube, as described earlier 

 in this chapter. 



Infection by rectum has been accomplished in experimental 

 amoebiasis and trichomoniasis and the use of the rectal plug is 

 recommended by some as enhancing the possibility of infection by 

 producing a stasis of the bowel. The dangers, however, of intes- 

 tinal obstruction and of producing secondary infection accompany- 

 ing the removal of the celloidin plug offset to a considerable degree 

 the advantage of a possible higher incidence resulting from its use. 

 The writer recommends that it be avoided wherever possible. If 

 the attempt to establish the infection is by the rectal method, the 

 kitten should be prepared previously by fasting for eighteen hours ; 

 occasionally it is advisable to administer an enema prior to giving 

 the infected material by rectum. The Luer syringe and French 

 catheter are indispensable in infection work with kittens. 



3. DOGS 



Endamoeba 



Spontaneous amoebic dysentery has been reported from the dog 

 by KartuHs (1891 and 1913) in Egypt, Darling (1915) in 

 Panama, Ware (1916) in India, Fischer (1918) in China and 

 Bauche and Motais (1920) in Cochin-China. Darling (1915) pro- 

 posed the name E. vcnaticum for the amoeba producing canine 

 dysentery but Wenyon (1926) favors the assumption that the 

 dysenteric amoeba found in dogs is the same as E. histolytica of 

 man. I 



Trichomonas (' I 



Trichomonas has been recorded from the dog by Brumpt (1925) 

 and by Chatterjee, Harendranath and Mitra (1927) from the 

 jackal. Brumpt (1925) considers his Trichomonas of the dog to 

 be the same as the common trichomonad found in the domestic cat. 

 The form found in India by Chatterjee was a pentaflagellate form 

 and was named P. canis-auri. The species seen by the writer in 

 Peking was also a Pentatrichomonas form and answered more to 

 the description of Chatter jee's form than to the common Trichom- 

 onas seen by the writer in man and in kittens. 



No experimental infection work has been reported thus far in 

 dogs with TricJiomonas hominis. In a series in progress by the 

 writer one of four puppies experimentally infected has acquired 

 the infection.
