What causes Bejel?
Bejel is a rare infectious disease caused by a spiral-shaped bacterium (spirochete), known as Treponema pallidum endemicum. Under a microscope, T. p. endemicum is virtually indistinguishable from Treponema pallidum, the bacterium that causes syphilis.
Is Treponema pallidum gram positive?
Treponema pallidum is a Gram-negative micro-aerophilic bacterium, 6–20 μm long, 0.1–0.2 μm wide and tightly coiled.
Is Treponema pallidum Gram positive or negative?
Treponema pallidum is a Gram-negative micro-aerophilic bacterium, 6–20 μm long, 0.1–0.2 μm wide and tightly coiled. The treponemes are motile by three flagella (axial filaments) that wrap around the surface of the organism and are covered by the outer membrane which contains lipopolysaccharide.
Is Bejel curable?
Bejel, also known as endemic syphilis, is a chronic but curable disease that is seen mostly in children in dry regions, such as parts of Africa (Sudan, southern Rhodesia, and South Africa), parts of the Middle East (among nomadic/Bedouin tribes of Saudi Arabia, Iraq, and Syria), and parts of Asia (Turkey, southeast …
Is syphilis a gram positive or negative bacteria?
Treponema pallidum can be considered a gram-negative bacterium although its cell envelope differs from other gram-negative bacteria. T. pallidum causes syphilis, a sexually transmitted disease that affects the skin and mucous membrane of the external genitalia, and also sometimes the mouth.
Can syphilis be Gram stained?
If syphilis is suspected, Giemsa staining should be performed in addition to Gram staining; these simple tests might aid in the early diagnosis of syphilis. The authors state that they have no Conflict of Interest (COI).
