Tree Of Life- Bacteria

Front 1

Spirochetes

Back 1

-gram negative
-motile
-chemoheterotrophic
-unique rotating axial filament (modified flagella)
-many human parasites, others free living
-syphillis, lyme disease

Front 2

Chlamydias

Back 2

-gram negative
-cocci or rod shaped
-extremely small
-live only as parasites
-trachoma, STDs, pneumonia

Front 3

High GC gram positives

Back 3

-aka Actinbacteria
-high GC/AT ratio in DNA
-elaborate branching
-some reproduce by forming chains of spore at tips of filaments
-most antibotics from this group
-TB, leprosy

Front 4

Cyanobacteria

Back 4

-phototrophs (chlorophyll a)
-many fix nitrogen
-contain internal membrane system
-eukaryote chloroplast from endosymbiotic chloroplast
-colonies in sheets, filaments, balls, spores, heterocysts (N fixation)

-

Front 5

Low GC gram positives

Back 5

-aka Firmicutes
-low GC ratio in DNA
-some produce endospores, can survive harsh conditions
-tough cell wall and spore coat
-anthrax, MRSA, staphlococcus
-

Front 6

Proteobacteria

Back 6

-largest grp of bacteria -high diversity
-gram negative
-includes some nitrogen fixing genera ex: rhizobium
-ecoli, plague, cholera, salmonella
