conditions for bacteria growth
- dark
- warm
- ph of 7
- food source
- moisture
- reproduces by binary fission (very quickly)
- one cell becomes 16,777,126 in 12 hours
-
staphylococci
- spheres aranged in cluster
- epidiermidis - normal skin flora
- -contaminant in blood culters
- aureus - skin infections
- - precurser to MRSA
- - bolts (pus,yellow,white, thick pus), surgical wounds
- staph epi - no infection
-
methicillin resistant staph aureus
from inappropriate antibiotic use

pneumoniae
pneumonia with the risk of meningitis
-
pneumococcus
causes many forms of
- pneumonia
- ear infections
- sinus infections
- meningitis
-
bacilli
- rod shaped
- form spores
- very hard to kill (only thing that kills is an autoclave)
- most are acaerobic and gram negative
- live in deep dark places
-
bacilli spores
can make shell and hybernate for up to one year and when they have proper conditions they break shell and reproduce
-
aerobic bacilli
- myobacterium tuberculosis - TB
- haemophilus infuenza - eare infections can cause pneumonia or meningitis
- vaccination available - HiB

- nosocomial
-
colostridium bacilli
- tetani - tetanus
- botulinum - botulism (lives in honey)
- perfingens - food poisoning
