1
Q

what are the 4 fungal divisions we need to worry about

A

chytridiomycota, zygomycota 1 and 2, ascomycota, basidiomycota

2
Q

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

A

seen on food spoilage

3
Q

two types of zygomycota

A

zygospore (sexual)

sporangiospore (asexual)

4
Q

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

A

parasites of arthropods and mammals

1000 known species of moulds

5
Q

how many species of ascomycota

A

over 31,000 known species with 44 families

6
Q

what percentage of pathogenic fungi are ascomycota

A

> 90%

7
Q

what are examples of ascomycota

A
penicillium (produces the antibiotic penicillin)
candida albicans (saccharomycetaceae family)
8
Q

how may known species of basidiomycota

A

over 64,000

9
Q

what do basidiomycota produce

A

some produce toxins or hallucinogenic compounds

10
Q

type of fungi and class basidiomycota belong to

A

macrofungi (mushroom + puffballs)

class: homobasidiomycetes

11
Q

example of basidiomycota

A

agaricus

12
Q

how many species of chytriomycota and how many are pathogenic

A

more than 900 species with only one being pathogenic

chytridion means little pot in greek: fun fact

13
Q

unique features of chytriomycota

A

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

14
Q

negative aspects of fungi

A
  • food spoilage
  • pathogenic to humans and animals (mycose) –> true and opportunistic pathogens
  • infection of plants and crops
15
Q

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

A
systemic
subcutaneous
cutaneous
superficial
opportunistic
mycotoxins
16
Q

biofilms are used for what microorganisms

A

bacteria and fungi (candida sp)

17
Q

third leading cause of intravascular catheter related infections

A

yeast

18
Q

advantages of biofilm

A

increases resistance
resist host immune response
act as reservoir

19
Q

where can algae be found

A

freshwater, marine, sometimes terrestrial

20
Q

medical significance of algae

A

associated with intoxication/food poisoning

21
Q

how does one get food poisoning from algae

A

toxic algae ingested by fish which is then ingested by humans

22
Q

examples of fish we eat that can lead to algae poisoning

A

barricades, snappers, ciguatera, paralytic shellfish poisoning

23
Q

respiratory symptoms in algae poisoning is linked to

A

red tides

24
Q

zoonotic protozoal diseases of companion animals

A
  • Toxoplasmosis (T. gondii)
  • Giardiasis (Giardia sp.)
  • Babesiosis (Babesia sp.)
  • Trypanosomiasis (T. cruzi)
  • Leishmaniasis (Leishmania sp. )
25
Q

what is cell wall of algae made of

A

cellulose

26
Q

what microorganisms sometimes has more than one nucleus

A

protozoa

27
Q

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

A

protozoa
