Domain Bacteria

Different bacterial groups exhibit diverse characteristics and play various roles in ecosystems and human health. Fusobacteria include species producing antibiotics and causing diseases in animals and humans.

Domain Bacteria

Domain Bacteria

Fusobacteria

baillales
bacullus

Subtopic

disease in cattle sheep and horses that can be transmitted to humans

causes anthrax

some produce anti-biotics

only feww are pathogenic to humans

common in soil

rods that produce endospores

clostridails
epulopiscium

large enough to be seen by the unaided eye

clostridium

lives in intestinal tract

foodborne diarriha

botulinum

cause tetanus

resistance to heat and many chemicals

contains endo spores

rod-shapes

Deinocci
thermus aquaticus
Dienococcus radiodurans
Spirochaetes
leprospira
Borrelia
treponema
Purple and Green Photosynthestic Bacteria
chromatium
Chloroflexus
Fusobacterium

Nonprotepbacteria Gram- Negative Bacteris

Bacteroidetes
Cytophaga
Bacteroudes
Panctomycetes
Chlamydiae
Chylamydiae and Chlamydophila
Cyanobacteria

Probacteria

deltaproteobacteria
myxcoccus

preditor on other bacteria

move by gliding leaving a trail of slime

vegatave cells

desulfovibrio

uses sulfur rather than oxygen

Sulfu-reducing bacteria

bdellovibrio

after attatching it reproduces

attacks gram negatives

Gammaproteobacteria
Enterobacteriales
Vibrionellales

vibria

Legionellas

coxiella

legionella

pseudomonadales

acinetobacter

moraxella

azobacter and azomonas

Pseudomonas

Francisella

causes turlaremia

grows in comples media enriched with blood tissue extracts

small pleomorphic bacteria

Beggiatoa

accumulates granules of sulfur

uses hydrogen sulfade as an energy source

attatches to the surface

production of slime

mobility is by gliding

grows in aquadic sediments

Betaproteobacteria
Zoogloea

as they grow they form fluffy slimmy masses

important in sewage treatment process

Neisseria

causes gonorroea and meningitis

lives in mucus membrane of animals

bordetella

cause of whooping cough

Burkholderia

grows in disinfectant solutions

problem for people with cystic fibrosis

capable degrading 100 different organic molocules

single polar flugellum

Shaertoltius

gram negative

sewage

fresh water

Spirillum

arobic

relativly large

mainly in fresh water

Thiobacillus

involved in decomposition of organic material

important in sulfur cycle

sulfur oxidizing

epsilonproteobacteria
helicobacter

most common cause of peptic ulcers adn stomach cancer

curved rods with multipul flagellum

campylobactor

outbreaks in food born intestinal disease

can cause spontainous aborthion in domestic animals

each cell has one polar flugellum

Enterobacterials
enterobacter

lives in humans, animals, water, sewage, and soil

hospital aquired infections

can cause urinary tract infection

erwinia

causes soft rot diseases

primarly plant pathogens

yersinia

contact from respitory dropplets from infected aminal

urban rats and ground squarels carry fleas transmitt it

causes the plague

proteus

found in wombs

causese urinary tract infects

as a result the colony concentric rings

outside cells have flagella for movement and the inside have fewer

swarmers

serratia

can be found in sterile solutions

can cause urinary tract infection

distinguished by red pigment

klebsiella

can cause serious forms of pmeumonia

found in soil or water

shigella

can cause life threatning dysentery

causes bacillary dysentery or shigellosis/ only found in humans

salmonella

causes typhoid fever

identified by the letters KOH

commonly found in the intestines of animals :especially pultry and cattle.

almost all members are pathogenic

escherichia

causes urinary tract infections and traveler's diarrhea and occasionally very serious foodborne diseases

its presence in water and food indicate fecal contamination

most common inhabitants of the intestinal tract

Alphaproteobacteria
Nitrobacter and Nitrosomanas

reduce nitrogenous compounds

important to agriculture

capable of using inorganic chemicals

genra of nitrifying bacteria

brucella

important for bodies defense against bacteria

cause brucellosis

agrobacterium

causes crown gall

does not induse root nodules

invade plants

Rhizobium and Bradyhizobium

form nodules result in nitrogen fixation

known by rhizobia

specifically infect roots of beans peas and clover

Bartonella

cat-scratch disease

contains several human pathogens

Caulobactor and hyphomicrobium

produce prominent prosthecae

low-nutrient aquadic environments

use budding process to reproduce

able to anchor

found in placesd like lakes

Ehrlichia

cause ehrlichiosis

transmitted by ticks

live in white blood cells

gram-negative
