Session 13 Flashcards
Where are microbes on the human body
Skin, oral cavity, gastrointestinal tract, respiratory tract, urogenital tract
What is referred to as the superorganism
This is the host and the natural flora of the host.
What is the microflora
These are different microbial communities in a certain environment
What is dysbiosis
This is when a change occurs within a human microflora relative to when it is healthy
What are the three groups of microbes that live on the human body
Benign, beneficial microbes, and opportunistic microbe
Why is gram-positive bacteria more abundant on the skin
They are more capable of surviving the dryness and saltiness of the skin compared to gram-negative bacteria
How is a baby affected by microflora if it has none when its a fetus
When the baby is born and passes through the mother’s vagina it gets a lot of beneficial microbes on its skin.
What are the two groups of microbe on skin
resident microflora and transient microflora
What is the difference between resident microflora and transient microflora
Resident microflora basically live permanently on the skin while transient are able to be removed through things like handwashing and competition with resident microbes
What are the factors that can change gut microflora
Antibiotics, illness, stress, diet, age
Why can oral ingestion of antibiotics be dangerous
Kill normal microflora in the GI tract which can result in diarrhea and this can cause antibiotic-resistant bacteria to be the dominant species which can cause further infection
