Weil-Felix reaction is based on sharing of antigens between
Answer: C
Correct answer: rickettsial antigens and antigens of certain strains of Proteus
The Weil-Felix reaction works by heterophile agglutination: certain Proteus strains, OX-19, OX-2 and OX-K, happen to share carbohydrate antigens with the rickettsiae, so serum from a patient with typhus agglutinates them. The pattern of which strain is agglutinated points to the rickettsial group. It is convenient rather than accurate, and specific serology has largely replaced it.
