Two ways septicemia may be acquired
- 1) primary- staph is directly injected into the blood
- 2) secondary- staph leaks into the blood from another infection (tooth)
Two forms of staph septicemia:
- Rapid progression- profound toxemia with death within a few days
- Slow progression- most frequent. Spreads slowly throughout the body

TSS - toxic shock syndrome
TSS disease course
- Incubates in 12-24 hrs
