Flashcards in Bacteria Deck (13):
1

Phylum Proteobacteria

largest most diverse group- rickettsia (ticks and fleas)

2

Phylum Firmicutes

mycoplasma- lacks a cell wall, possibly the smalles bacterial cell

3

Phylum Actinobacteria

fungal-like in their growth - branched filaments
mycobacteria- TB, leprosy

4

Phylum Cyanobacteria

pigmented algae, photosynthesis-chlorophyll- -02 production

5

Phylum Chlamydiae

very small- grow only in living tissue
-obligate intracellular parasite

6

Phylum spriochaetes

body moves in helical pattern
STD- syphillis

7

Phylum Euryarchaeota

recognize as archaea

8

methanogens

anaerobic (O2 kills), produce methane gas

9

extreme halophiles

aerobic, live in high salt concentrations

10

hyper thermoacidophiles

high temperatures

11

bacillus

"rod shaped"
diplobacillus- two
streptobacillus- chain of rods

12

coccus

"spherical, very small"
diplococcus- cocci remain in pairs after reproducing
streptococcus- cocci form a chain after reproducing
tetrad- four cocci forming a square
sarcina- cube-like packet of eight
staphylococcus- grapelike cluster of cocci

13

spiral

"can take 3 forms"
vibrio- curved rods that are comma shaped
spirilla- helical shape with rigid cell wall and flagella
spirochetes- endoflagella- corkscrew
