Shape 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 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...

Bacteriol. 82:909912. 1961.-Suspensions of Treponema pallidum, prepared by extracting the testes of syphilitic rabbits with normal rabbit serum or with a culture medium, were shaken with Amberlite IRC-50 resin in the sodium ion form. ...
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 کاملOxygen uptake by Treponema pallidum.
Virulent Treponema pallidum has been shown to consume O(2) at a rate similar to that of the known aerobic spirochaete, Leptospira. Such O(2) uptake is cyanide sensitive, indicating a functioning cytochrome oxidase. Inhibition of O(2) uptake by azide, chlorpromazine, and amytal further suggests a functioning electron transport system for the oxidation of nicotinamide adenine dinucleotide (reduce...
