The child is admitted to intensive care because the doctor thinks he has a type of pneumonia whose name you do not recognize. The doctor reports that the hospital has seen a dozen pediatric cases of this pneumonia in the past week. The doctor swabs your son’s nose but says the results won’t be back for several days. In the meantime, they will give supportive therapy, including an inhaled spray, but no antibacterial drugs. The doctor feels sure the child will recover. 1. What kind of pneumonia is it? 2. Why aren’t they giving him antibacterial drugs? 3. How can the doctor be sure what’s causing the pneumonia if she doesn’t yet have test results? 4. Has the other child (a 3 years-old) been exposed to the infection?arrow_forwardA 65-year-old woman has a long-term central venous catheter for intravenous therapy. She develops fever and subsequently has multiple blood cultures positive for Staphylococcus epidermidis. All of the S. epidermidis isolates have the same colony morphology and antimicrobial susceptibility pattern, suggesting that they are the same strain. In what possible way do you think she has contracted the bacteria? Which link in the chain of infection has broken in this particular scenario and what will be your advice to avoid such infections?arrow_forward
