Which of the following is a difference between transient and resident microbiota?
Transient microbiota are pathogenic, and resident microbiota are not.
Resident microbiota remain on the host for an extended period.
Humans do not have transient microbiota.
Transient microbiota can be opportunistic pathogens, and resident microbiota cannot.
Resident microbiota cause disease and transient microbiota do not.
Which of the following situations does NOT demonstrate the importance of a healthy microbiome?
Group of answer choices
Anthony suffers from debilitating diarrhea after a lengthy course of antibiotics to treat his MRSA infection.
Andy is lactose intolerant. His body does not break down lactose, so the microorganisms in the gut do it for him.
Mary suffers from colon cancer. While being treated, she develops an opportunistic Bacteroides fragilis infection.
Jenna is prone to yeast infections, so she routinely eats yogurt and takes a probiotic supplement to increase the amount of lactic acid bacteria in her vagina.
The term "colonization" is best described as:
a large group of unicellular organisms
presence of bacteria on our body that may not necessarily cause harm
a virus that will colonize bacteria and make the disease more virulent
all of the above
