Treponema pallidum subsp. pertenue displays pathogenic properties different from those of T. pallidum subsp. pallidum.
The present study described the susceptibility of C4D guinea pigs to cutaneous infection with Treponema pallidum subsp. pertenue Haiti B strain. The general manifestations of the disease in adults and neonates differ, to a certain degree, from those induced by T. pallidum subsp. pallidum Nichols strain. Noticeable differences between the infections were reflected in the character of the skin le...
متن کاملThe Direct Cultivation of Treponema Pallidum Pathogenic for the Monkey
A method for the direct cultivation of Treponema pallidum from human syphilitic lesions, by the employment of a solid medium, has been described. By means of it, three of the four strains worked with were successfully cultivated. The several pure cultures agree in morphological and cultural characters, grow only in the presence of sterile tissue under anaerobic conditions, and do not produce pu...
متن کاملShape of Treponema pallidum.
Treponema pallidum was found to be not helical, but a flat wave twisted into one to five different planes per cell.
متن کاملTreponema pallidum in nerve fibres.
Ultrathin sections of a rabbit scrotal syphiloma were examined by electron microscopy. Treponemes were observed in the endo-, peri-, and epineurium of the nerve fibre. The significance of these findings, in that infection may be transmitted via the nerve fibres and pain reduced by damage to the afferent fibres, are discussed.
متن کاملMucopolysaccharidase of Treponema pallidum.
Treponema pallidum (Nichols strain) exhibited mucopolysaccharidase activity. Acidic mucopolysaccharides were broken down more rapidly by viable treponemes than by heat-inactivated treponemes or membrane filtrates of treponemal suspensions. Ouchterlony immunodiffusion demonstrated the occurrence of antibodies to the hyaluronidase-like enzyme within syphilitic sera. After intratesticular inoculat...
