A nurse colleague asks for your help in drawing blood cultures from a patient with suspected bacteremia. You notice that he has handed you two bottles, each with a different colour label. What is the reason for having two different culture bottles? Question 17 options: a) One bottle is used to identify Gram positive organisms and the other bottle helps identify Gram negative organisms b) There is no reason for two bottles. The microbiology laboratory only needs one bottle c) One bottle is used for aerobic bacteria and the other bottle is used for anaerobic bacteria d) One bottle is used to identify the bacterial organism, and the other bottle is used as a back-up in case the microbiology laboratory needs a larger sample

Question 5 You spread a small amount of a water sample from the environment on an enriched media agar plate. After 24 hours, the plate is covered with many small yellow colonies. Does this plate contain a pure culture of bacteria? ○ No, because it came from the environment, there are lots of different organisms. ○ We know there are multiple species present, but each colony is a different species. ○ Yes, we know the plate contains a pure culture because there are individual colonies. ○ We do not know if the plate contains a pure culture or a mixed culture. or even if individual colonies are pure or mixed based on their appearance alone.
