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)
