Protozoa and Syphilis 375 



PROTOZOA AND SYPHILIS. 



Dohle * succeeded in staining certain protoplasmic bodies 

 in the tissues in syphilis, which resembled bodies he had 

 previously encountered in the discharges. They were for 

 the most part round or oval, sometimes with irregular out- 

 line, and provided with flagella. They were stained in a 

 mixture of hematoxylon and carbol-fuchsin, subsequently 

 treated with iodin and washed in alcohol. 



Convinced that these bodies were the cause of syphilis, 

 he excised small fragments from gummata and other 

 syphilitic tissues, and placed them beneath the skin of 

 guinea-pigs, which subsequently fell ill with a chronic 

 marasmus which ultimately caused death. 



The work of Schullerf upon the protozoan parasite of 

 syphilis is worth perusal.
