- 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.arrow_forwardWhat is a microbiome? What is the human microbiome and how is it important to human health? What do we know about the human microbiome in general? Provide a general introduction to these topics and make sure to emphasize the importance of the microbiome.arrow_forwardDescribe how the composition of the normal microbiota can change over time.arrow_forward
- Are normal microbiota beneficial to their host? Why?arrow_forwardA microbiologist argued that there is no such thing as “normal” microbiota of the human body, since the population is dynamic and is constantly changing, depending on diet and external environment. What would be an argument against this microbiologist’s view?arrow_forwardWhich major body sites are heavily colonized by microbes?arrow_forward
- How does intercellular invasion and colonization differ from intracellular invasion and colonization? Which type of colonization is utilized by necrotrophs? Which type of colonization is utilized by biotrophs?arrow_forwardCan you give examples of microbiomes?arrow_forwardhow could antibiotics designed to stop narrowly defined categories of infectious microbes be used to discover which organisms are mutualists and which are parasites or commensals in the termite gut?arrow_forward
