Ability of a pathogen to grow extremely rapid and cause direct damage to surrounding tissues

Ability of an organism to cause infection depending on an organism’s ability to evade or overcome body defenses

Severity or harmfulness of an organism to cause the disease in a minimum number

Any drug that is effective by slowing the growth of the bacteria, allowing the body’s natural defenses to eliminate the pathogen

Any natural substance produced by bacteria that can kill other bacteria

Any drug that is effective against pathogens used to treat bacterial, fungal, viral, or parasitic infections

Rod-shaped bacteria

Bacteria with thick cell wall and retain a purple color after staining

Bacteria that grow best without oxygen

Spiral-shaped bacteria

Bacteria with thin cell wall lose its purple stain and retain its pink color

Bacteria that thrive in an oxygenrich environment to survive

Mechanisms of Action of Antibacterial Drugs: Antimetabolites

Mechanisms of Action of Antibacterial Drugs: Cell Wall synthesis inhibitors

Mechanisms of Action of Antibacterial Drugs: Protein synthesis inhibitors

Mechanisms of Action of Antibacterial Drugs: RNA synthesis inhibitors

Antibiotics should be prescribed only when there is a clear rationale for their use

It is always easier to prevent an infection than to treat one. This includes teaching patients the importance of getting immunizations to protect against diseases such as influenza, tetanus, polio, measles, and hepatitis B, COVID-19

This includes applying standard infection control procedures and teaching patients the methods of proper hygiene for preventing transmission in the home and community settings
