Rabbits were examined 2-3 times/week; blood and cerebrospinal fluid (CSF) were collected weekly and every 2 weeks, respectively 2012-09-20 All species of Treponema pallidum including the subspecies consist of a thin coiled structure which allows it to move in a corkscrew motion to travel through the body. Due to being too thin however, it is impossible to use Gram staining to physically see the bacteria. Treponema pallidum ssp. pallidum pallidum ssp.

Description and significance Treponema pallidum is a Gram-negative bacteria which is spiral in shape. It is an obligate internal parasite which causes syphilis, a chronic human disease. Syphilis is a sexually transmitted disease but transmission can also occur between mother and child in utero; this is called congenital syphilis. T. pallidum can be localized on formalin fixed paraffin embedded tissue; the antibody has a rabbit purified IgG fraction (J Cutan Pathol 2004;31:595) Essential features Immunohistochemical stain for T. pallidum is more sensitive (71% sensitive) than silver stains - Warthin-Starry or Steiner (41% sensitive) ( J Cutan Pathol 2004;31:595 ) Gram Stain: Gram-negative, difficult to stain.

Treponema pallidum gram stain

The Treponema pallidum antibody immunohistochemical (IHC) stain has improved our ability to detect the organism histologically. We present a case of a man with genital condyloma acuminatum with a positive T. pallidum IHC stain but negative T. pallidum serologies and no syphilitic symptoms. 2020-03-18 · By thebradleylab In Atypical Syphilis is caused by the bacterium Treponema pallidum, which is a Gram-negative organism but it’s hard to stain because the cell wall is too thin. We call this organism a spirochete based on its really interesting corkscrew shape. It wiggles and twists in a unique way called rotary motion.

It is very difficult to grow in culture because unlike most bacteria, it cannot survive outsi Read More.

It is the causative agent of syphilis, plays a role in the transmission and acquisition of HIV, and is a major cause of stillbirth and perinatal morbidity in the developing world. Spirochetes are a class of bacteria which are characterized by their corckscrew-like shape and unique spiral motility. The architecture of the spirochete cell wall is similar to that of gram negative bacteria and contains a peptidoglycan layer sandwiched between lipid inner and outer membranes (See: Bacterial Cell Wall).
