Terminal electron transport in Treponema pallidum.
Reduced-minus-oxidized difference spectra of sonically treated virulent Treponema pallidum disclosed cytochromes of the b anc c types as well as large amounts of flavoprotein. Difference spectra of the carbon monoxide-binding pigment identified cytochrome o as the terminal oxidase. Physiological reduction of the cytochromes indicated that the cytochrome system was functional and established the...
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...
متن کاملAzithromycin resistance in Treponema pallidum.
PURPOSE OF REVIEW Although the recommended treatment for syphilis is penicillin, azithromycin has been used as an alternative. We discuss azithromycin-related treatment failures and resistance in Treponema pallidum, and propose ways to meet the resulting clinical and public health challenges. RECENT FINDINGS Azithromycin treatment failures in syphilis were first noted in San Francisco in 2002...
