IHC stain highlighted a patchy distribution of organisms within the granulation tissue taken from the anal mass, in some areas with a perivascular pattern, with rare organisms identified in the rectal mucosal biopsy samples.
The present study has evaluated the performance of Vitros ECi Syphilis Treponema Pallidum
antibody chemiluminescence immunoassay as a screening test for syphilis in blood donors using the reverse algorithm.
Validation of serological tests for the detection of antibodies against Treponema pallidum
in nonhuman primates.
Evaluation of immunoglobulin M and G Western blot and ELISA for screening antibodies to Treponema pallidum
in blood donors.
The research of Treponema Pallidum
with coloring of Warthin-Starry identified images compatible with the morphological appearance of the germ.
pallidum hemagglutination T pallidum: Treponema pallidum
UGH: University of Gondar Hospital VDRL: Venereal disease research laboratory.
hemagglutination assay was reactive in a titer of 1:4.
Enhanced molecular typing of treponema pallidum
: geographical distribution of strain types and association with neurosyphilis.
Congenital syphilis is preventable with proper antenatal follow-up and treatment of the pregnant woman infected with Treponema pallidum
, and the rapid evaluation and early treatment of the newborns.
We did a rapid plasma reagin (RPR) test and a Treponema pallidum
particle agglutination test; we also tested for human immunodeficiency virus (HIV).
