I'm having trouble identifying the following etiologic spirochete agents based o the following signs and symptoms:

 

a) patint has only flu-like symtpoms, agent can be isolated and cultured on artificial media

 

b) patient has mutliple lesions on the body and suffers from headaches, fever, and sore throat

a.) sounds like it could be Borrelia burgdorferi (Lyme disease) or a close relative Borrelia hermsii, which causes relapsing fever. Note: B. burgdorferi can be cultured, but it is very difficult

 

b.) Possibly a non-venereal syphilis caused by a species of Treponema, either T. pertenue, T. endemicum or T. caroteum
