Question

You look in the refrigerator and find some orange drink you had forgotten was there. The drink now has an "off" taste and bubbles. What is the most likely explanation for the changes in the drink? Would you expect all EIDs to be on the notifiable infectious disease list? Explain. Situation 14.2 9. 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. Refer to Situation 14.2 What is the normal habitat of this gram-negative, facultatively anaerobic, non-endospore-forming, lactose-positive rod? Provide a plan for identifying source of infection and preventing further infection.

Explanation / Answer

Answer to question 7- When orange juice is left for many days, certain microbes such as bacteria,yeast, etc.. These microbes ferment the sugar present in juice and this leads to formation of alcohol and carbon dioxide gas. Alcohol is responsible for off taste and CO2 for bubbles.
