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 کاملMucopolysaccharides in suspensions of Treponema pallidum extracted from infected rabbit testes.
The amount and nature of mucopolysaccharides present in extraction fluids routinely obtained in the isolation procedure of Treponema pallidum from infected rabbit testes was investigated. The mean quantity of mucopolysaccharides extracted from both testes of groups of 10 rabbits was 3.09 mg after infection for seven days and 26.88 mg after infection for 12 days, while from the testes of uninfec...
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 کاملBinding of aminoglycoside antibiotics to acidic mucopolysaccharides.
Binding of aminoglycoside antibiotics to acidic mucopolysaccharides has been studied by means of physicochemical methods. Reactivity was affected markedly by the ionic environment , e.g. pH and ionic strength of the medium, the concentrations and the molar ratios of the constituents. The ionic character of binding was further confirmed by gel chromatography. The reduction of metachromasis by an...
متن کاملGenetics of Treponema: relationship between Treponema pallidum and five cultivable treponemes.
Three genetically distinct groups of treponemes have been identified by saturation reassociation assays using 125I-labeled treponemal DNAs. The three groups are (i) virulent Treponema pallidum (Nichols strain), (ii) T. phagedenis and its biotypes Reiter and Kazan 5, and (iii) T. refringens biotypes Nichols and Noguchi. There is no detectable DNA sequence homology (less than 5%) among the three ...
