Colestasis intrahepática por Treponema pallidum en paciente inmunocompetente

Biomédica: revista del Instituto Nacional de Salud, 2023
La hepatitis por Treponema pallidum es una entidad poco frecuente y su diagnóstico representa un reto clínico. Treponema pallidum debe considerarse como etiología presuntiva en todo paciente con enfermedad hepática aguda, en el cual se hayan descartado ...

Pyruvate oxidation by Treponema pallidum [PDF]

Infection and Immunity, 1979
Cell-free extracts of Treponema pallidum catalyzed the decarboxylation of pyruvate. This activity was suppressed at low O2 tensions and appeared to be coenzyme A independent. Pyruvate decarboxylation was inorganic phosphate dependent, and evidence suggested that acetyl phosphate was a product.

Time series model based on global structure of complete genome [PDF]

, 2000
A time series model based on the global structure of the complete genome is proposed. Three kinds of length sequences of the complete genome are considered. The correlation dimensions and Hurst exponents of the length sequences are calculated.

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

Advanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

The pan-genome of Treponema pallidum reveals differences in genome plasticity between subspecies related to venereal and non-venereal syphilis

BMC Genomics, 2020
Background Spirochetal organisms of the Treponema genus are responsible for causing Treponematoses. Pathogenic treponemes is a Gram-negative, motile, spirochete pathogen that causes syphilis in human. Treponema pallidum subsp.

Epidemic of venereal treponematosis in wild monkeys: a paradigm for syphilis origin

New Microbes and New Infections, 2020
Treponema pallidum infections have been primarily known as slightly contagious mucocutaneous infections called yaws (tropical Africa and America) and bejel (subtropical North Africa). T.

Cryo-electron Tomography Elucidates the Molecular Architecture of \u3ci\u3eTreponema pallidum\u3c/i\u3e, the Syphilis Spirochete [PDF]

, 2009
Cryo-electron tomography (CET) was used to examine the native cellular organization of Treponema pallidum, the syphilis spirochete. T. pallidum cells appeared to form flat waves, did not contain an outer coat and, except for bulges over the basal bodies ...
