CASE HISTORY
Brandon,a 30-year-old stockbroker living in Chicago,visited his physician's office.When the nurse asked Brandon why he was there,he blushed and said he wanted to talk only to the physician about his problem.Once the doctor entered the room,Brandon explained he had a small round lesion on his penis.When asked about his sexual partners,Brandon initially said he was dating only one woman,but when pressed,he admitted he had been intimate with two women over the past month and one man.Upon examination,the lesion appeared to cause no pain but exuded a clear fluid.The physician quickly sent a sample of the fluid to the clinical laboratory.There the sample was found to contain highly motile,corkscrew-shaped bacteria.The diagnosis was syphilis,caused by the bacterium Treponema pallidum.Left untreated,the disease could eventually cause horrible disfiguration and death.Confident that he knew the cause,the physician gave Brandon a shot of long-acting penicillin.
What signs and/or symptoms of disease (distinguish between the two in your answer)did Brandon's doctor note as a part of this diagnosis?
