Chapter 14 Short Response Discussion Board Questions
Please thoroughly answer the following:
1. A 37-week-old infant was delivered by cesarean section and discharged from a Connecticut hospital when he was ten days old. Two days later he was lethargic and had a fever. When he was readmitted to the hospital, he had multiple brain abscesses caused by Citrobacter diversus. After a prolonged illness, the baby died. A second infant with a normal pregnancy and delivery died of C. diversus meningitis after a short illness. Nine infants in the hospital nursery had umbilical cord colonization by C. diversus. Environmental cultures were negative for hospital equipment. What is the normal habitat of this gram-negative, facultatively anaerobic, non-endospore-forming, lactose-positive rod? Provide a plan for identifying the source of infection and preventing further infection. (Module 14.7)
2. Zika virus infection, a zoonotic disease, produced somewhat sizable outbreaks recently in certain areas of Central America, but not in the U.S (although there were some infected individuals uncovered in the U.S.). Provide two plausible explanations for this dichotomy, and explain. (Module 14.8)
3. Salmonella Heidelberg gastroenteritis occurred on three cruises aboard the T.S.S. Festivale. The figure below shows on-board clinic visits for diarrheal illness between February 10 and March 3. Explain the incidence pattern shown on the graph. What are probable modes of transmission? What changes would you recommend before the ship books more cruises after March 3 (Module 14.9) (GRAPH ATTACHED)
