- Antibacterials
- chemicals that prevent the growth and multiplpication of bacteria
- what are some differences between virusues and bacteria?
- viruses are smaller, viruses are non-cellular, virusues vary in shape and structure, viruses can only reproduce inside the cells of living organisms
- Alexander Flemming
- Attributed for the discovery of the mold that helped Staphylococcus aureus (causes boils)
- How do viruses replicate?
- penetrate the living host cell and inject their DNA, takes over biomechanical mechaniery inside cell, causing cell to die. then the cell makes new DNA/RNA and formes new viruses

- interferes with enzymes that bacteria need to make normal cell wall
- What is MRSA?
- a "super bug" because it can make beta lactamase which can degrade penicillin

- what is Benzylpenicillin
- the orignial penicilin
- What is the basic structure that all penicillins contain?
- four-membered ring containing a nitrogen atom known as a BETA-LACTAM RING
- Infect surface areas such as the skin or the respiratory tract
- Aerobic
