Chapter 27, Problem 5MCQ
The water used to prepare intravenous solutions in a hospital contained endotoxins. Infection control personnel performed plate counts to find the source of the bacteria. Their results:

| Boiler | 0 |
| Hot water line | 300 |
All of the following conclusions about the bacteria can be drawn except which one?
- a. They were present as a biofilm in the pipes.
- b. They are gram-negative.
- c. They come from fecal contamination.
- d. They come from the city water supply.
- e. none of the above

This agar plate was obtained by spreading 0.1 ml of a 1:1,000 dilution of a bacterial sample taken from cole slaw, and then incubating at 37oC for 24h. This plate indicates that:
a. there are 42 bacteria/ml on the cole slaw
b. there are at least 4 different types of bacteria in the cole slaw
c. there are approximately 42,000 bacteria/ml in the cole slaw sample
d. there are approximately 420,000 bacteria/ml in the cole slaw
e. these bacteria cannot cause illness because they came from the person’s skin who made the cole slaw
Which of the following methods is most sensitive for identifyingdifferent strains of a microbe?a. microscopic examination
b. hemolysis on blood agar
c. DNA analysis
d. agglutination test
Two patients, with identical medical histories are in adjacent hospital beds. Each is infected
with Streptococcus pneumoniae. Patient A's infection progresses to pneumonia while
Patient B's infection resolves quickly. The microbial stain of the lung fluid from Patient A
indicated the bacterial cells had a capsule, while Patient B's lung fluid stain did not. Why
did the capsule affect the course of the infection in Patient A?

They grew bacterial colonies of Salmonella typhimurium in petri dishes labelled A, B and C. The Petri dishes were kept at 36°C for 48 hours, with scientists observing the bacteria every 24 hours. The results for this investigation are below. Petri dish A B с Treatment Was subjected to ionising radiation followed immediately by a dose of antibiotic X An equal amount of antibiotic X was added (as was added to Petri dish A) Was given neither ionising radiation nor antibiotic X After 24 hours Small spots of growth on surface No growth Growth across whole surface After 48 hours (ii) Identify the purpose of petri dish C. Large spots of growth on surface No growth Growth across whole surface (i) Explain the effect of the ionising radiation on the bacteria.

- answer and explain the rationale plsarrow_forwardA glass flask is rinsed and autoclaved after use. It was then filled with sterile media in a sterile environment and covered. A few days, microbial growth appears in the flask. Assume the media and sterile environment is guaranteed to be sterile. What most likely caused the growth in the flask? a. The flask has to be rinsed with bleach before autoclaving b. A portion of the flask was not exposed to the steam c. Autoclaves only sanitize equipment, so you cannot expect the flask to be sterile d.

Imagine you have a rash on your foot. You're concerned that it's an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium vs a eukaryote? You decide to use lab supplies to get a basic understanding of the pathogen. Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab. What is one experiment you could do, involving culturing the organism?arrow_forward
