The cyanobacterium Synechococcus averages about 0.5 to 1.6 μm in diameter. Treponema pallidum is a corkscrew-shaped (spirochete) bacterium. It thrives in moist regions of the body and will survive and reproduce only where there is little oxygen present. It is killed by heat, drying, and sunlight. Therefore, one cannot catch syphilis from contact with toilet seats, bath towels, or bedding. Treponema pallidum pallidum is the most widespread and common out of all of the Spirochete that is able to harm humans through sexual transmission.

pallidum is a subspecies of the Treponema genus and a microaerophilic bacterium that belongs to the spirochetal order. It is characterized by a thick phospholipid membrane and a very slow rate of metabolism, requiring approximately thirty hours to multiply; even so, T. pallidum is a difficult-to-eradicate pathogen and responsible for the sexually-transmitted disease Structure  Thin, delicate, Helically coiled, corkscrew-shaped       organisms. 10 to 14 μ long and 0.1 to 0.2 μ wide. Have 8-24 sharp and angular spirals, at regular intervals of about 1 μm Ends are pointed with finely spiral terminal filaments.
