Immunofluorescent staining of Treponema pallidum and Treponema pertenue in tissues fixed by formalin and embedded in paraffin wax.
The main problems in identifying Treponema pallidum in tissues are optical definition contrast, and specificity. In general, fluorochrome staining provides optical definition and contrast superior to that obtained by ordinary tinctorial staining, and in theory improved resolution. Specificity is lacking however, as with other stains. In contrast, immunofluorescence should combine the optical ad...
متن کاملOsteitis in the dens of axis caused by Treponema pallidum
BACKGROUND Syphilis has been referred to as "the great imitator" due to its ability to imitate other diseases. Untreated syphilis becomes a systemic infection that can involve almost every organ systems. Treponema pallidum has a high affinity for bone tissue, but osteitis has mainly been described in late stages of the disease. Vertebral involvement is rare, and this is to our knowledge the fir...
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...
متن کاملSpecific immunofluorescence staining of Treponema pallidum in smears and tissues.
To date, tissue sections prepared from Formalin-fixed tissues have not been successfully stained with Treponema pallidum subspecies-specific antibody in a direct fluorescent-antibody assay. While current methods stain T. pallidum, they do not distinguish T. pallidum from other spirochetes such as Borrelia burgdorferi (E. F. Hunter, P. W. Greer, B. L. Swisher, A. R. Simons, C. E. Farshy, J. A. C...
متن کاملStudies on Treponema Pallidum and Syphilis. Ii. Spiroch~ticidal Antibodies against Treponema Pallidum. by Hans
In a previous communication we have reported on the agglufinins which are formed in rabbits following systematic inoculation with concentrated culture material of Treponema pallidum. Incidentally it may be stated that a sheep has also been successfully used. The antigen used for the immunization of these animals was similar to that employed in the first agglutination experiments, except that we...
