The rash seems to be mostly concentrated on the trunk region. Eventually, the lesions burst and form a crusty scab. The patient is also experiencing a fever, chills, as well as tiredness. What is the most likely disease/infection and etiology? Is a vaccine available? If so, what is it? disease: syphilis etiology: Treponema pallidum treatment: Penicillin G vaccine: no Amanda attends a party at her university and has unprotected sex. She feels tenderness near her inguinal lymph nodes (region: groin) about 10 days later. She does not worry because she does not feel pain in this region and she cannot indicate alternate symptoms. The aforementioned tenderness soon passes. However, Amanda notices tenderness in her inguinal lymph nodes once again about 14 days later. Amanda wakes up the next morning to intense abdominal pain and heavy vaginal bleeding. She was rushed to the ER, where a stain of the exudate revealed the pathogen (see stain below). What is the most likely disease/infection and etiology? What is one common antimicrobial medication used to treat it? Is a vaccine available? If so, what is it? disease: hot tub rash and otitis externa etiology: Pseudomonas aeruginosa treatment: polymyxin B and acidic ear drops with antibiotics Several cases of skin rash infections reported at a hotel in Bangor, Maine. Sample of unknown pathogen taken from draining ear of 6 year old child and the pool filter (Gram stain shown). 9 patients infected. Had rash for 7 days (or less) or an outer ear infection. All had spent time in either the pool or hot tub. 7 spent time in both. What is the most likely disease/infection and etiology? What is one common antimicrobial medication used to treat it? disease: Trichomoniasis etiology: Trichomonas vaginalis treatment: metronidazole An 18 year old girl presents to her pediatrician with her mother for her pre-college check-up. She has no past medical history. After her mother leaves the room for the social history component, the girl admits to having sex with her boyfriend for the first time two weeks ago and complains of a yellow green malodorous vaginal discharge that started a week ago. She endorses mild pelvic pain. A pelvic exam is performed and mild cervical tenderness is noted. The cervix is pink, nulliparous, inflamed and is covered by small red punctate spots. A thin yellow green frothy discharge of fishy odor is also detected. A wet prep is made and reveals squamous cells and numerous motile organisms (see images). What is the most likely disease/infection and etiology? What is one common antimicrobial medication used to treat it? disease: diphtheria etiology: Corynebacterium diptheriae antimicrobial: penicillin vaccine: DTaP A young patient (5 years) is experiencing an accumulation of pus, RBC, dead host cells & fibrin on their tonsils (in severe cases intubation is required due to potential suffocation from this accumulation on the tonsils) They also experienced some lesions on their skin. A gram stain is shown here. A PCR diagnostic test can be used to detect a toxin that this pathogen produces (which in severe cases can spread throughout the body & damage the heart or nerves). What is the most likely disease/infection and etiology? What is one common antimicrobial medication used to treat it? Is a vaccine available? If so, what is it?
