Step 1
Yaws is a bacterial infection caused by Treponema pallidum subspecies pertenue. Both are treponemal diseases, but they are caused by different subspecies of the same bacterium. Show more…

A pregnant 18-year-old woman came to the Ford County urgent-care clinic with a low-grade fever, malaise, and headache. She was sent home with a diagnosis of influenza. She again sought treatment 7 days later with a macular rash on her trunk, arms, hands, and feet. Further questioning of the patient when serology results were known revealed that one month previously, she had a painless ulcer on her vagina that healed spontaneously. The same day, patient #2 sought medical treatment for a penile ulcer. In a routine examination, patient #3, a pregnant female, had positive serologic tests for this disease but was asymptomatic. Patient #4 was tested because of her sexual contact with patient #2. She had no symptoms and a positive serologic test. Patient #5, a contact of patients #3 and #6, was also serologically positive. He frequently traveled to a neighboring county, which reported a 290% increase in this disease over the preceding year. Patient #6, a female, had a rash and also tested positive. Patients 1 and 2 were in drug-abuse rehabilitation; these two were the only two who reported use of crack cocaine. Discussion Questions What is syphilis? What is its causative agent and how is it transmitted (spread) to its host(s)? What are the host(s) for the causative agent of syphilis? What virulence factors are associated with the microbe that cause this disease? What serologic tests are used to diagnose syphilis infections? In the above case study, what are the stages of the disease observed in Patients 1 and 2? What medical interventions (i.e. treatments) can be applied in this case for the above patients? What are the consequences of not treating this infection?

Which of the following is false concerning spirochetes? The primary lesion (similar in appearance to a fever blister) of syphilis is called the chancre. They are all transmitted by direct contact. They also cause Lyme disease, infectious jaundice, and relapsing fever. Secondary syphilis is characterized by a maculopapular rash. Tertiary syphilis includes dementia, aortic aneurysms, and gummas.
INFECTIOUS DISEASE CASE STUDY 18: Syphilis Shelly, a 27-year-old "call girl," has had rapidly deteriorating health recently. She is experiencing malaise, persistent mild fever, and hair loss. She recently recovered from what she thought was some sort of allergic reaction. She experienced a generalized skin rash of varying appearance. At the same time, she had painless lesions in her mouth and throat. While this rash lasted approximately three weeks, Shelly did not seek medical attention, since it caused her no discomfort. 1. Name the microorganism that causes syphilis. Type answer as two words, using appropriate capitalization and one space between each word. 2. These microorganisms have which bacterial morphology? A) Spirochete B) Bacillus C) Curviform bacteria D) Coccus 3. What stage of this illness is Shelly experiencing? A) Latent Period B) Tertiary Stage C) Secondary Stage D) Primary Stage 4. The skin rash of varying appearance is a characteristic of which stage of syphilis? A) Primary Stage B) Secondary Stage C) Latent Period D) Tertiary Stage
