Transcript of Treponema Pallidum

Treponema Pallidum Treponema Pallidum is a helical-shaped bacteria that is sexually transmitted or transmitted through an umbilical cord during pregnancy. The bacterium travels to either the blood or the lymph nodes to infect them. One of its most interesting characteristics is that it contains an endo-flagella. The endo-flagella is what gives it its helical shape. Another interesting fact about this bacterium is that it cannot be exposed to heat or oxygen or it will die, thus making it an obligate anaerobe Treponema Pallidum is a know cause of syphilis, a disease causing painful sores on the genitals or mouth, or a rash on the hands or the feet. It lacks the enzymes needed for the citric acid cycle and oxidative phosphorylation, so the only way it can obtain energy is through glycolycis. Treponema Pallidum is of no good use to humans, but we can use it to gain more knowledge of syphilis and yaws. However, the bacterium is hard to grow in a lab because of its intolerance to air and heat. Most often, scientists use rats as an experiment on the bacterium. By Charlotte Bernot and Elyza Wylder A vaccine for syphlilis and yaws is currently unavailable, but treatment is. Penicillin is used as a treatment, and is injected into a patient at different amounts depending on how far along either disease is. Another known disease associated with Treponema Pallidum is yaws, a tropical infection of the skin, bones, and joints tansmitted by skin-to-skin contact.
