|caused |by |microorganisms |that |have |gained |access |to |the |human |body.

Uncle |Billy |Bob |is |nervous. |Three |of |his |prize |winning |roosters, |Huey, |Dewey, |and |Louie, |at |Billy
|Bob's |Ranch |for |Interesting |Chickens |have |developed |sores |on |their |beaks |consistent |with |a
|condition |called |beak |rot. |Dr. |Strummer |visits |the |ranch, |takes |samples |from |the |sores |of |the |three
|diseased |chickens, |and |brings |the |samples |back |to |his |research |lab. |He |isolates |bacteria |from |the
|each |sample |(Huey, |Dewey, |and |Louie) |and |grows |them |in |three |SEPARATE |culture |tubes. |He |then
|injects |aliquots |(small |portions) |of |each |diluted |culture |into |the |backs |of |5 |healthy |laboratory
|chickens |that |are |sterile |and |lack |any |disease |immunity. |After |3 |days |the |laboratory |chickens
|injected |with |bacteria |cultured |from |the |samples |of |Huey |and |Dewey |have |sores |on |their |beaks
|similar |to |those |observed |in |Huey |and |Dewey. |Chickens |injected |with |bacteria |cultured |from |the
|samples |of |Louie |are |perfectly |healthy.Is |the |cause |of |Huey's |beak |rot |- |correct |answer |-Yes,
|because |bacteria |isolated |from |Huey's |sore |sample |were |able |to |cause |sores |in |laboratory |chickens
|consistent |with |Koch's |3rd |postulate.

The |human |may |be |permanently |colonized |with |the |microorganism.
The |human |may |be |transiently |colonized |with |the |microorganism.
The |colonizing |microorganism |may |cause |disease |in |the |human.
