Flashcards in Microbial classification Deck (25):
1

4 general classes of microorgs.

1. bacteria
2. virus
3. fungi
4. parasites

2

what can be seen with what

light microscope for everything but viruses, some fungi and parasites with naked eye

3

features of a bacteria

- single celled
- prokaryote
- strong wall of proteoglycan
- no membrane bound organelles or nucleus

4

3 basic divisions of bact

1. gram stain
2. aerobic/anaerobic - tolerance of O2
3. shape

5

features of pos and neg gram stain

pos - has thick cell wall
neg - thin call and extra layer of membrane

6

2 basic shapes of bact.

1. cocci
2. bacilli - rods

7

2 types of cocci

1. chains
2. clusters

8

4 types of aerobes

1. strict aerobes - depend on aerobic resp
2. facultative aerobes - can use both
3. mircoaerophilic - depend on aerobic resp., but killed by too much O2
4. aerotolerant - uses anaerobic resp, but can tolerate O2

9

one type of anaerobe

strict - uses anaerobic resp and killed by O2

10

4 types of atypical bact

1. intracellular
2. lack rigid cell wall
3. acid-fast
4. spirochetes

11

3 Gram+ O2 Cocci

1. staphylococcus
2. streptococcus
3. enterococcus

12

2 Gram+ O2 bacilli

1. cornybacterium
2. bacillus

13

1 Gram+ anO2 bacilli

clostridium

14

2 Gram- O2 Cocci

1. neisseria
2. haemophilius

15

1 gram- O2 bacilla

E coli

16

1 gram-, anO2, bacilli

bacteroides

17

def. virus

acellular DNA surrounded by a protein coat (capsid)

18

main division of viruses

DAN vs. RNA

19

subdiv. of viruses

1. single/double stranded
2. envelope
3. capsid shape

20

2 DNA viruses

1. Hep B
2. Herpes

21

5 RNA viruses

1. Hep ACE
2. Flu
3. HIV
4. Rotavirus
5. Norovirus

22

def. fungi

eukaryotic uni and multicellular org with walls made of chitin and produce sexually or asexually

23

2 main classes of fungus

1. yeast
2. filamentous

24

def. parasites

eukaryotic uni-multucellular orgs that live within another org,

25

2 main classes of parasites

1. protozoa
2. helminths
