Gram Negative Spiral
A 27-year-old white man presents to his family doctor complaining of being tired all the time and having a slight fever for the past two weeks. He recently returned from a trip to Las Vegas, where he indulged in some of the infamous nightlife. His physical exam is unremarkable except for a macular rash over his trunk and on the palms of his hands. There are no lesions or ulcers on the penis. What organism is causing this man's illness? (AIPG 2009)
a. Treponema pallidum is usually transmitted through unprotected sexual activity with an infected individual.
b. This man presents with the symptoms of secondary syphilis, which includes malaise, mild fever, and rash on the palms or soles of the feet.
c. The primary lesion (chancre) may go unnoticed because it is painless and subsides in a few weeks. Neisseria gonorrhea is associated with a serous exudate.
d. Chlamydia is associated with painful urination.
e. Rickettsia rickettsii and Borrelia burgdorferi are associated with arthropod vectors.
