a. Why does syphilis have such profound effects on the human body?
b. Why is long-term immunity to syphilis so difficult to achieve?

To determine:
Why syphilis has such profound effects on human body and why is it difficult to achieve long-term immunity to it.
Introduction:
Syphilis is caused by the spirochete Treponema pallidum. It is a strict parasite that has complex growth requirements and this necessitates cultivating them in live cells.
Explanation of Solution
Humans act as sole natural host for the parasite. It is an extremely fastidious and sensitive parasite that cannot survive outside the host for long time and is rapidly destroyed by heat, drying, disinfectants, and other adverse conditions. It is transmitted sexually. Hence, it has such profound effects on human body. Protective immunity does not arise in case of humans against the syphilis pathogen and this makes vaccination difficult. Hence, long-term immunity to it is difficult.
Hence, it may be concluded that, humans being the sole host for parasite, syphilis has profound effect on humans and the ability to obtain protective immunity against it makes long-term immunity difficult.

- A 25-year-old woman presents to the emergency department with a 2-day history of fever, chills, severe headache, and confusion. She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes.
