Formation of multiple treponemes
Zentralblatt für Bakteriologie, 1994The formation of pseudomulticellular treponemes was analyzed using different electron microscopical methods such as thin sectioning, freeze fracturing and scanning electron microscopy. The development of spherical bodies is preceded by the formation of unseparated helical forms and plait-like structures.

On the antiquity of treponemal infection
Medical Hypotheses, 1989Documentation of the treponemal etiology of reactive bone formation in a pleistocene bear supports unprecedented antiquity of treponemal bone infections. The spectrum and implications of osseous treponemal disease in the New and Old World are reviewed in light of past perspectives and contemporary investigative techniques.

Archives of Ophthalmology, 1971
To the Editor. —In reference to the article entitled "Uveitis and Intraocular Treponemes" by Randolph Whitfield, MD, and Emil Wirostko, MD, ( Arch Ophthal 84 :12-15, 1970), I would like to point out the similarity between the "treponemes" shown in their photomicrograph and what we have termed "glass shavings" in our article "Treponema-like Forms and ...

New species of rumen treponemes
Folia Microbiologica, 2006Three strains of rumen treponemes were isolated and partially characterized. The strains differed significantly one from another in morphology, fermentation characteristics and plasmid profiles. Their genetic variability was assayed using DNA-based molecular approaches. Easily differentiated ARDRA (amplified ribosomal DNA restriction analysis) patterns

Molecular and Antigenic Analysis of Treponemes
Critical Reviews in Microbiology, 1990The treponemes comprise the essentially non-cultivable Treponema pallidum subspecies (agents of syphilis, yaws and other human trepanematoses), the gut pathogen of pigs, T. hydysenteriae, and a group of antigenically related, cultivable species, some of which are strongly implicated in human periodontal or gastrointestinal disease.

Treponemal infection in a Pleistocene bear
Nature, 1987The age and origins of the organisms that cause syphilis (treponemes) have long been matters for controversy. The widely-held belief that Columbus's ship brought the disease from the New World to Europe rests on identification of the classic lesions in Inca, Aztec and Mississippian bones that date from 1,000 to 3,000 years before present.

Variability of treponemes in the rumen of ruminants
Folia Microbiologica, 2010Complete 16S rRNA sequences were determined of recently proposed new species of treponemes designated strain S and T. Sequence comparison indicated that both species belong to the Treponema saccharophilum cluster, having thus at least 5 cultivable representatives.

Lipid catabolism of cultivated treponemes
Canadian Journal of Microbiology, 1982Treponema require long-chain fatty acids for growth in vitro. Serum, added to culture media, provides a source of long-chain fatty acids. These fatty acids, however, are esterified to triglycerides, phospholipids, and cholesterol. In this study, the major pathways of complex lipid catabolism in T. phagedenis, T. denticola, T. refringens, T.

STUDIES WITH THE TREPONEMAL IMMOBILIZING TEST
Journal of the American Medical Association, 1954The widespread use of the standard serologic tests for syphilis and the known occurrence of a sizeable number of biologically false positive serologic tests has created a major problem in diagnosis. No solution to this problem had been offered until 1948, when Nelson1developed the treponemal immobilizing test.

Can the Treponeme Stage a Comeback?
Archives of Dermatology, 1956Since the peak of the nationwide syphilis epidemic was reached in 1946 and 1947 the rate of new syphilitic infections has declined by 93%. * Figure 1 demonstrates that the rate of fall is similar in the white and in the Negro, although the absolute decline is much greater in the Negro.
