1

The two types of CELLULAR etiologic agents of infectious disease are:

1. Eukaryotic
2. Prokaryotic

2

Prokaryotic cells are also known as ___

Bacteria

3

The main type of A-CELLULAR etiologic agent of infectious disease is ____

Viruses

4

This type of A-Cellular etiologic agent is due to misfolded proteins

Prions

5

Name the 3 types of Eukaryotes

1. Fungi
2. Protozoa
3. Helminths (worms)

6

Which 2 types of eukaryotes are known as the parasites?

1. Protozoa
2. Helminths

7

Do prokaryotic cells (bacteria) have a nucleus?

No

8

Do prokaryotic cells have a cell wall?

Yes

9

Put these in order from smallest to largest: Bacteria, Virus, Red Blood Cell, Yeast

1. Virus
2. Bacteria
3. Yeast
4. RBC

10

There is no cholesterol in ____ membranes

Bacterial

11

___ can be formed inside bacteria, get released, and have increased heat resistance and chemical resistance

Endospores

12

___ are sites of protein synthesis inside prokaryotic cells

Ribosomes

13

Gelatinous, sticky substance surrounding the outside of a bacterial cell. Composed of polysaccharides, polypeptides, or both

Glycocalyces

14

Name the two types of glycocalyces

Capsule, slime layer

15

Which glycocalyx is highly organized, may prevent bacteria from being recognized by host and slow down phagocytosis, and has something to do with "virulence factor"?

Capsule

16

This type of glycocalyx has a less organized structure, is water-soluble, and its stickiness allows prokaryotes to attach to things

Slime layer

17

Name the structure of bacterial cells that is responsible for motility. It is not present on all bacteria, however

Flagella

18

Name the external structure of bacterial cells that is are sticky, bristle-like projections used for adherence to other surfaces, and shorter than flagella.

Fimbriae

19

This external structure of bacterial cells is a hollow tube (proteinaceous), longer than fimbriae, but shorter than flagella, typically only 1 or 2 per cell, and it's purpose is to transfer DNA from one cell to another (conjugation)

Pili (pilus = singular)

20

What are the two basic types of bacterial cell walls?

1. Gram positive (purple)
2. Gram negative (pink)

21

Name the common component of both types of bacterial cell walls

Peptidoglycan

22

Which type of bacterial cell wall contains a thick layer of peptidoglycan and contains unique polyalcohols called teichoic acid?

Gram-positive

23

Staphylococcus aureus and streptococcus pyogenes are examples of gram-_____ bacteria

Positive

24

This type of gram-positive bacteria has up to 60% mycolic acid and actually stains pink. Examples of diseases caused by it are tuberculosis and leprosy

Acid-fast

25

Which type of bacterial cell wall is more complex and has a thinner peptidoglycan layer?

Gram-Negative

26

Name the unique thing on the exterior of the outer membrane of a gram-negative bacteria

Lipopolysaccharides

27

The outer membrane of gram-negative bacterial cell walls contains phospholipids, proteins, and lipopolysaccharides. This is also called _____

Endotoxin

28

E. Coli and Salmonella are examples of gram-____ bacteria

Negative
