| Questão | Responda |
| VIRUSES | - Either RNA or DNA (never both) - Have a protein capsule called capsid - Inject living mediums and use them to multiply |
| BACTERIA | - Rigid cell wall - Circulas Chromosome lacking nucleus - Both DNA and RNA - Binary fission to multiply |
| MYCOPLASMA | Similar to Bacteria but lacking a rigid cell wall |
| RESIDENT vs. TRANSIENT | Resident bacteria exists naturally in our body (gut flora). Transient bacteria (whether good or bad) is foreign to our bodies |
| LIGANDS | Ligands are present on the surface of the bacteria, able to bind to specific receptors |
| OPSONIZATION | When someone can't be taken by a phagocyte, antibodies go and attack the capsule which then allows it to be taken by phagocytosis. (Antibodies to the capsule) |
| COMPLEMENT | A complex system of plasma proteins that work together to resist bacterial infection |
| CONTAMINATION | A bacteria enters but there is no multiplying |
| COLONIZATION | A bacteria enters and multiplies, but there is no disease |
| CLINICAL INFECTION | A bacteria enters, multiplies, and a disease occurs |
| SUBCLINICAL vs. CLINICAL INFECTION | Clinical infection has apparent symptoms so it is easier to diagnose. Subclinical infections do not have apparent symptoms so they are harder to diagnose |
| PATHOGENICITY | Ability to produce disease |
| VIRULENCE | Ability (capacity) to cause disease |
| TOXIGENICITY | Ability to produce potent toxins |
| VIRULENCE FACTORS (factors that help a bacteria achieve its goal) | Pilli, capsule, toxins, enzymes |
| EXOTOXINS | - Excreted by living cells - Specific to a certain thing - More potent and dangerous |
| ENDOTOXINS | - Excreted by a dying cell (last resort) - Not as specific - Less potent and dangerous |
