Microbiota
In healthy humans, the internal organs and tissues such as muscles, the brain, and blood do not
contain microorganisms. However, surface tissues, such as the skin and mucous membranes,
are in continuous contact with environmental microbes and become readily colonized by
specific bacteria. The population of microbes regularly found in the body is referred to as the
normal microbiota. The term transient microbiota refers to members of the normal microbiota
that are present for only a short time before disappearing. A person's normal microbiota is an
important part of the immune system, as the normal microbiota often inhibit pathogenic
microbes from colonizing the host, a process called microbial antagonism. Different types of
bacteria will colonize different niches in a person's body due to variations in moisture level, pH.
atmospheric pressure, oxygen levels, and body secretions. Accordingly, different types of medila
must be used to culture the various human microbiota.
If…
Normal microbiota provide protection from infection in each of the following ways EXCEPT:
Question 3 options:
A)
they produce antibacterial chemicals.
B)
they compete with pathogens for nutrients.
C)
they make the chemical environment unsuitable for nonresident bacteria.
D)
they produce lysozyme.
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.
