Transient flora

Hint 1

Front 2

Resident Flora

Back 2

Microbes that are always present in a particular area of the body

Front 3

Transient flora

Back 3

Microbes that stay in/on the body for a short amount of time and then move on or die off

Front 4

What type of relationship does the normal microbial flora have with the human body?

Back 4

Symbiotic relationship

Front 5

Symbiotic relationship

Back 5

A close interaction between two different organisms

Front 6

Types of symbiosis

Back 6

Mutualism

Commensalism

Parasitic

Front 7

Mutualism

Back 7

Helpful

i.e E. coli

Front 8

Commensalism

Back 8

Harmless

i.e. Staphylococcus epidermidis

Front 9

Parasitism

Back 9

Harmful

i.e H1N1 and Taenia

Front 10

Explain the nature of the mutualistic relationship between humans and e.coli

Back 10

- E.coli is part of the normal flora of the large intestine

- It synthesizes vitamin K and B vitamins which are absorbed by our normal metabolism

- In exchange, we provide a warm, moist environment with a steady flow of nutrients

Front 11

Opportunistic infection

Back 11

When conditions allow members of normal flora that are typically not pathogenic to take over and cause disease

Front 12

What is an example of an opportunistic infection?

Back 12

Staphylococcus aureus (which is normally found on the skin) sometimes gets into a wound or burn and becomes pathogenic

Front 13

What was the predominant gram reaction and morphology of the normal flora of the class?

Back 13

Gram + cocci
