What is RPR?
RPR (rapid plasma reagin) is a screening test for syphilis. It measures substances (proteins) called antibodies that are present in the blood of people who may have the disease.
What caused syphilis?
The cause of syphilis is a bacterium called Treponema pallidum. The most common way syphilis is spread is through contact with an infected person’s sore during sexual activity. The bacteria enter the body through minor cuts or abrasions in the skin or mucous membranes.
What is Pinta disease?
Pinta is a rare infectious tropical disease affecting the skin that is caused by the bacterium Treponema carateum, which is transmitted by direct, nonsexual contact. Pinta progresses through three distinct stages, which are characterized by various skin lesions and discoloration.
Can poor hygiene cause syphilis?
BACKGROUND. CAUSATIVE AGENTS. Syphilis is a chronic infectious disease caused by the spirochaete Treponema pallidum. Syphilis is usually transmitted by sexual contact or from mother to infant, although endemic syphilis is transmitted by non-sexual contact in communities living under poor hygiene conditions.
