Study Notes
Types of Hosts
- Four types of hosts exist: Intermediate host, Transfer host, Vector, and Reservoir host
Staphylococcus aureus (S. aureus)
- S. aureus produces resistant strains against Methicillin
- S. aureus is resistant to Drying
- S. aureus is resistant to Light
- S. aureus is resistant to Heat
- S. aureus is resistant to NaCl (sodium chloride)
Positive Lance-shaped Diplococcus
- Streptococcus pyogenes (S. pyogenes) and Streptococcus pneumonia (S. pneumonia) are positive, lance-shaped diplococcus
- S. pyogenes and S. pneumonia undergo lysis in a few minutes with 5-10% CO2
- S. pyogenes and S. pneumonia undergo lysis in a few minutes with 10% Ox bile
