Which of the Following is Characteristic of Yersinia Pestis Infections

Question

Which of the following is characteristic of Yersinia pestis infections?
A) petechiae
B) a "bull's-eye" rash
C) jaundice
D) arthritis
E) buboes

Accepted Answer

Yersinia pestis infections are best known for causing the formation of buboes, which are swollen and painful lymph nodes, typically in the groin, armpit, or neck regions. Buboes are one of the hallmarks of bubonic plague, which is the most common form of Y. pestis infection. Other symptoms may include fever, chills, weakness, and headache, but petechiae, a "bull's-eye" rash, jaundice, and arthritis are not typically associated with this type of infection.
