Treponema pallidum was successfully grown in subcutaneous chambers in golden hamsters. Abnormally long forms of T. pallidum were found in these chambers. The cause of this abnormality may possibly be due to their being coated with antibody which could inhibit cell division or render the organism avirulent or both. T. pallidum was successfully passaged between hamsters but with a possible diminu...
Treponema pallidum subsp. pallidum and/or its nucleic acid can be detected by various methods such as microscopy, rabbit infectivity test or polymerase chain reaction (PCR) tests. The rabbit infectivity test for T. pallidum, although very sensitive, has been discontinued from most laboratories due to ethical issues related to the need for animal inoculation with live T. pallidum, the technicall...
Treponema pallidum subsp, pallidum, the causative agent of the sexually transmitted disease syphilis, is a fastidious, microaerophilic obligate parasite of humans. This bacterium is one of the few prominent infectious agents that has not been cultured continuously in vitro and consequently relatively little is known about its virulence mechanisms at the molecular level. T. pallidum therefore re...
Genetic relationships among two strains of Treponema pallidum (Nichols and KKJ) and a strain of T. pertenue were determined by measuring the degree of deoxyribonucleic acid sequence homology. The results in indicated that these three virulent, noncultivable treponemes were genetically indistinguishable. Like T. pallidum (Nichols), T. pertenue (Gauthier) had no detectable deoxyribonucleic acid s...
DOAK, G. 0. (University of North Carolina, Chapel Hill), LEON D. FREEDMAN, AND JOHN W. CLARK, JR. Ionic requirements of Treponema pallidum. III. Divalent ions. J. 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. ...
INTRODUCTION Due to the existence of a variety of types of non-venereal syphilis caused by the related T. pallidum, regular serological testing such as Rapid Plasma Reagin (RPR) and Chemiluminescent Microparticle Immunoassay Technique (CMIA) are often unable to differentiate venereal syphilis from the non- venereal one, hence, the interest in the use of molecular biology testing for a confirmat...
