soil bacterium
grows in roots of plants such as tropical grasses
nitrogen fixation

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

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
