inhabit mucus of upper respitory tract, mouth vagina and intestinal tract.

require blood

cause meningitis

cause epiglottis

septic arthritis in children, bronchitis and phneumonis

causes sexually transmitted disease chancroid

Alphaproteobacteria

pelagibacter

most abundant microorganisms on earth

marine Microbe

extremely small

live in low nutrient enviroment

azospirillum

soil bacterium

grows in roots of plants such as tropical grasses

nitrogen fixation

acetobacter and Gluconbactor

industrially important

convert ethanol into acetic acid

Rickettsia

reproduce only in mammalian cell

they are transmitted to human from bites from insects

responsible for many diseases related to spotted fever

Ehrlichia

gram-negative

live in white blood cells

transmitted by ticks

cause ehrlichiosis

Caulobactor and hyphomicrobium

found in placesd like lakes

able to anchor

use budding process to reproduce

low-nutrient aquadic environments

produce prominent prosthecae

Bartonella

contains several human pathogens

gram-negative

cat-scratch disease

Rhizobium and Bradyhizobium

specifically infect roots of beans peas and clover

known by rhizobia

form nodules result in nitrogen fixation

agrobacterium

invade plants

does not induse root nodules

causes crown gall

brucella

cause brucellosis

important for bodies defense against bacteria

Nitrobacter and Nitrosomanas

genra of nitrifying bacteria

capable of using inorganic chemicals

important to agriculture

reduce nitrogenous compounds

Enterobacterials

escherichia

most common inhabitants of the intestinal tract

its presence in water and food indicate fecal contamination

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

salmonella

almost all members are pathogenic

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

identified by the letters KOH

causes typhoid fever

shigella

causes bacillary dysentery or shigellosis/ only found in humans

can cause life threatning dysentery

klebsiella

found in soil or water

nitrogen fixation

can cause serious forms of pmeumonia

serratia

distinguished by red pigment

can cause urinary tract infection

can be found in sterile solutions

proteus

swarmers

outside cells have flagella for movement and the inside have fewer

as a result the colony concentric rings

causese urinary tract infects

found in wombs

yersinia

causes the plague

urban rats and ground squarels carry fleas transmitt it

contact from respitory dropplets from infected aminal

erwinia

primarly plant pathogens

causes soft rot diseases

enterobacter

can cause urinary tract infection

hospital aquired infections

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

epsilonproteobacteria

campylobactor

each cell has one polar flugellum

can cause spontainous aborthion in domestic animals
