- Classes of Infectious Microorganisms
- Bacterial Infection
- Viral Infection
- Fungal Infection
- Parasitic & Protozoal infection
- Pathogen: Microorganisms that cause disease.
- Relationship with humans
- Symbiosis: Benefits humans & does not harm the microorganism
- Mutualism: Benefits humans & microorganism
- Commensalism: Benefits microorganism & not harm the human
- Pathogenicity: Benefits microorganism & harms the human
- Opportunism: A benign microorganism becomes pathogenic because of decreased human host resistance
- Process of infection Colonization Invasion Multiplication Spread
- Clinical Infection Disease Process
- 1. Incubation Period: Interval between exposure to infection agent & appearance of first symptoms
- 2. Prodromal Stage: Appearance of initial symptoms which are often mild including feeling of discomfort & tiredness
- 3.Invasion Period: Pathogen multiplying rapidly, invading further, affecting tissues at site of initial colonization & other areas
- 4. Convalescence Period: Individuals immune & inflammatory systems have in general successfully removed infectious agents.
- 3.Invasion Period: Pathogen multiplying rapidly, invading further, affecting tissues at site of initial colonization & other areas
- 2. Prodromal Stage: Appearance of initial symptoms which are often mild including feeling of discomfort & tiredness
- 1. Incubation Period: Interval between exposure to infection agent & appearance of first symptoms
- Bacteria Shapes: Spherical, Rodlike & spiral
- Bacteriemia: Bacteria being transported in the blood due to failure of body's defence mechanisms to infect other organs or multiplying in the blood (Sepsis)
- Microorganisms: Any organism too small to be seen by the naked eye.
