Treponema pallidum is a helically shaped bacterium with high motility consisting of an outer membrane, peptidoglycan layer, inner membrane, protoplasmic cylinder, and periplasmic space. [9] It is often described as gram-negative , but its outer membrane lacks lipopolysaccharide , which is found in the outer membrane of other gram-negative ...
The fluorescent treponemal antibody absorption (FTA-ABS) test is a diagnostic test for syphilis.Using antibodies specific for the Treponema pallidum species, such tests would be assumed to be more specific than non-treponemal testing such as VDRL but have been shown repeatedly to be sensitive but not specific for the diagnosis of neurosyphilis in cerebrospinal fluid (CSF).
Treponema is a genus of spiral-shaped bacteria. The major treponeme species of human pathogens is Treponema pallidum, whose subspecies are responsible for diseases such as syphilis, bejel, and yaws. Treponema carateum is the cause of pinta. [2] Treponema paraluiscuniculi is associated with syphilis in rabbits. [3]
Treponematosis is a term used to individually describe any of the diseases caused by four members of the bacterial genus Treponema. The four diseases are collectively referred to as treponematoses: [1] Syphilis (Treponema pallidum pallidum) Yaws (Treponema pallidum pertenue) Bejel (Treponema pallidum endemicum) Pinta (Treponema carateum)
It is caused by the bacterium Treponema pallidum subspecies pallidum when it infects the baby after crossing the placenta or from contact with a syphilitic sore at birth. [4] [5] It is not transmitted during breastfeeding unless there is an open sore on the mother's breast. [4] The unborn baby can become infected at any time during the ...
Treponema pallidum subspecies pallidum is a spiral-shaped, Gram-negative, highly mobile bacterium. [ 11 ] [ 22 ] Two other human diseases are caused by related Treponema pallidum subspecies, yaws (subspecies pertenue ) and bejel (subspecies endemicum ), and one further caused by the very closely related Treponema carateum , pinta .
Treponema pallidum, a spirochate bacterium, is the main cause of syphilis, which spreads drastically throughout the body and can infect all its systems if not treated appropriately. Treponema pallidum is the main cause of the onset of meningeal syphilis and other treponemal diseases, and it consists of a cytoplasmic and outer membrane that can ...
Bejel, or endemic syphilis, is a chronic skin and tissue disease caused by infection by the endemicum subspecies of the spirochete Treponema pallidum. Bejel is one of the "endemic treponematoses" (endemic infections caused by spiral-shaped bacteria called treponemes), a group that also includes yaws and pinta.
