S. Pneumoniae has two strains:
Strains that secrete capsules look _________ and can cause _________ infections in mice
Strains that do not secrete capsules look _________ and infections are __________ in mice |
Smooth, fatal
Rough, not fatal |
|
|
Smooth strains (S) with capsule are fatal because |
Capsule prevents immune system from killing bacteria. (Living bacteria found in blood) |
|
|
Rough strains (R) without capsule are not fatal because |
No living bacteria found in blood |
|
|

They survive |
|
|
Mixing live R with heat-killed S |
Kills the mouse bc blood contains living S bacteria (TRANSFORMATION) |
