| Virulence | The degree of pathogenicity of a microorganism |
| Capsule | Virulence factor used by organism to resist phagocytosis |
| Exotoxin | Produced by Gram positives. Systemic effect with high toxicity and pathogenicity |
| Endotoxin | Produced by Gram negatives. Localized effect with low toxicity and antigenicity. |
| Opportunistic | An organism that doesn't cause harm to a healthy host but can cause disease in immunocompromised hosts. |
| Commensal | Lives on or in host without causing harm. I.E. Normal flora |
| Healthcare Associated Infection (HAI) | An infection acquired while in a medical facility (Formerly nosocomial) |
