Study Notes
Coagulase Test
- Used to differentiate between Staphylococcus aureus and Staphylococcus epidermidis
- Also used to differentiate between other bacteria, such as Neisseria meningitides, Streptococcus pyogens, and Enterococcus faecalis
Passive Diffusion
- Occurs due to concentration difference between two sides of the membrane
- Also occurs due to pressure difference between the two sides of the membrane
- Additionally, ionic difference can also be a driving force for passive diffusion
- All of the above factors can contribute to passive diffusion
