Bacteria Fresno Farmer with Fever

A 33-year-old male who practices veterinary medicine in Fresno (central California) is seen in the emergency room with chills, high fever, persistent unproductive cough, and generalized malaise. Physical examination reveals no evidence of pharyngitis, sinusitis, or otitis media. The patient does not have a rash and vehemently proclaims that he has not been bitten by any vectors. On his 10-acre farm, he raises sheep, cow and goats. Patients serum mixed with proteus antigen produced no agglutination.

Given the PE and history, which of the following is the most likely etiologic agent?

(A) C. pneumoniae
(B) C. psittaci
(C) C. trachomatis
(D) C.burnetti
(E) Ehrlichia canis

Would go with D, as it commonly infect ruminants( sheep, cow ..) and transmit to humans through inhalation.

I agree with everybody that it could be D, Q fever, but...., why not B.? It could also be Psittacosis?! i guess the types of animals he has on his farm is the hint for Coxiella, that is, Q fever.., but, if he had birds, too, I wouldn't be so sure anymore
