Review Question - QID 210923

A 21-year-old woman presents to her primary care physician for evaluation of a red rash. The rash covers her palms as well as the extensor aspects of her forearms and legs. She says that the rash is very itchy but not painful. She has never experienced this kind of rash before but thinks that it may be related to a fever she experienced 2 weeks prior to presentation. She did not seek medical attention at the time so she doesn't know the exact nature of the infection. Physical exam reveals raised lesions that appear as in Figure A. Rubbing of the skin does not lead to any skin separation. No blisters, fluid leakage, or areas of necrosis are observed. Which of the following describes an organism that is associated with the most likely cause of this patient's symptoms?
