What are the 6 types of microbes

1. Fungi
2. Protozoa
3. Algae
4. Prokaryotes (bacteria and Archaea)
5. Small Animals (helminths)
6. viruses

2

list the 6 types of microbes from smallest to largest

1. viruses
2. prokaryotes
3. protozoa
4. algae, small animals, and fungi

3

what are the three things that revolutionized human health against infectious disease

1. chlorination of water
2. Immunization
3. antibiotics

4

What are Fungi?

Eukaryotic heterotrophs that can be multi-cellular or unicellular with cell walls composed of Chitin and beta-glucans,

5

What are unicellular fungi called

Yeasts

6

what are multicellular fungi called

molds

7

how do yeasts reproduce

asexually by budding

8

how do molds reproduce

by sexual and asexual spores

9

which type of miccrobe causes:
ringworm
yeast infections (candidiasis)
histoplasmosis
coccidioidomycosis
cryptococcosis
pneumocystis pneumonia

fungi

10

What are protozoa

single-celled eukaryotes

11

where do you find protozoa

typically living freely in water, but some live inside animal hosts

12

how do protozoa reproduce

most often asexually

13

how are protozoa classified and what are the three classes of protozoa

they are classified by means of locomotion
1. pseudopodia
2. cilia
3. flagella
4. Non-motile

14

what are pseudopodia

cytoplasmic extensions that flow in the direction of travel

15

what are cilia

many short hair-like protrusions that propel protozoa

16

what are flagella

few, long, and whip like extensions that spin and move protozoa

17

What are algae

photosynthetic microbes with simple reproductive structures that can be either unicellular or multi-cellular.

18

are algae pathogenic

No, with one exception, their role in red tides and shellfish poisoning

19

What are prokaryotes

small unicellular and non-eukaryotic microbes

20

where do you find prokaryotes

any where there is moisture, even extreme environments

21

how do prokaryotes reproduce

asexually

22

what are the two kinds of prokaryotes

bacteria and archaea

23

What is found in bacterial cell walls, that helps distinguish them from other cells

peptidoglycan

24

are any known diseases caused by archaea

no

25

what are helminths

parasitic worms

26

what are the three main types of helminths

Cestodes = tapeworms (taenia)
Trematodes = Flukes (Schistosoma)
Nematodes = Roundworms (Ascaris)

27

What types of microbe causes malaria and amebiasis

protozoa

28

what type of microbe causes shellfish poisoning

algaea

29

what type of microbe causes TB and diphtheria

Bacteria (prokaryotes)

30

what type of microbe causes AIDS, influenza, West Nile, and SARS

virus'
