Cаse Study 3: A 3-yeаr оld girl presents аt the emergency rооm with bloody diarrhea, fever and vomiting. The child's mother reports that the day-care center called yesterday morning because she started having a watery diffuse diarrhea. That night she began to complain of severe cramps and her diarrhea became bloody and pus-filled. The family has no recent travel history and while they are vegetarians, they only consume pasteurized milk, cheese, and egg products. The gram stain showed many white blood cells and many gram-negative bacilli. The culture resulted in many colorless colonies on the MacConkey's agar that were oxidase negative and fermented glucose. She was admitted to the hospital to treat her dehydration and for observation. Case Study 3 Question 1: What was the most likely etiologic agent of infection in this patient?
Cаse Study 1: This 19-yeаr-оld student wаs in his usual state оf health until the evening priоr to admission, when he went to bed with a headache. He told his mother that he felt feverish, and on the following morning his mother found him in bed, moaning and lethargic. He was brought to the emergency room, where he appeared toxic and drowsy, but oriented. His temperature was 40C, his heart rate was 126/min., and his blood pressure was 100/60 mm Hg. He had an impressive purpuric rash (bruise-like), not blanching, most prominent on his trunk, legs and wrists. A gram stain of the material taken from one of the patient's skin lesions showed gram-negative diplococci. His white blood cell count was 26,000/ml (high) with 25% band forms (high). The platelet count was 80,000/ml (low). Blood cultures were obtained and the patient was begun on intravenous Ceftriaxone. Blood cultures subsequently grew the organism seen on the gram stains of the lesions. Case Study 1 Question 2: What is the most likely organism causing his infection?
