1

what are the 4 fungal divisions we need to worry about

chytridiomycota, zygomycota 1 and 2, ascomycota, basidiomycota

2

how does zygomycota pathogenic to humans - where is it found?

seen on food spoilage

3

two types of zygomycota

zygospore (sexual)
sporangiospore (asexual)

4

zygomycota are parasites of what? and about how many species are there?

parasites of arthropods and mammals
1000 known species of moulds

5

how many species of ascomycota

over 31,000 known species with 44 families

6

what percentage of pathogenic fungi are ascomycota

>90%

7

what are examples of ascomycota

penicillium (produces the antibiotic penicillin)
candida albicans (saccharomycetaceae family)

8

how may known species of basidiomycota

over 64,000

9

what do basidiomycota produce

some produce toxins or hallucinogenic compounds

10

type of fungi and class basidiomycota belong to

macrofungi (mushroom + puffballs)
class: homobasidiomycetes

11

example of basidiomycota

agaricus

12

how many species of chytriomycota and how many are pathogenic

more than 900 species with only one being pathogenic

chytridion means little pot in greek: fun fact

13

unique features of chytriomycota

motile asexual zoospores (via flagella): reflection of their aquatic habitat

14

negative aspects of fungi

-food spoilage
-pathogenic to humans and animals (mycose) --> true and opportunistic pathogens
-infection of plants and crops

15

human mycoses is a fungal infection and is classified by site or type of infection. what are some examples of these classifications?

systemic
subcutaneous
cutaneous
superficial
opportunistic
mycotoxins

16

biofilms are used for what microorganisms

bacteria and fungi (candida sp)

17

third leading cause of intravascular catheter related infections

yeast

18

advantages of biofilm

increases resistance
resist host immune response
act as reservoir

19

where can algae be found

freshwater, marine, sometimes terrestrial

20

medical significance of algae

associated with intoxication/food poisoning

21

how does one get food poisoning from algae

toxic algae ingested by fish which is then ingested by humans

22

examples of fish we eat that can lead to algae poisoning

barricades, snappers, ciguatera, paralytic shellfish poisoning

23

respiratory symptoms in algae poisoning is linked to

red tides

24

zoonotic protozoal diseases of companion animals

• Toxoplasmosis (T. gondii)
• Giardiasis (Giardia sp.)
• Babesiosis (Babesia sp.)
• Trypanosomiasis (T. cruzi)
• Leishmaniasis (Leishmania sp. )

25

what is cell wall of algae made of

cellulose

26

what microorganisms sometimes has more than one nucleus

protozoa

27

what microorganism does not have a cell wall and is motile (cilia, flagella, endoflagella)

protozoa
