Study Notes
Bacteriology Overview
- Bacteriology is the study of microorganisms known as bacteria.
- Bacteria are minute, one-celled organisms found nearly everywhere on Earth.
Types of Bacteria
- Nonpathogenic Bacteria: Harmless organisms that decompose refuse and enhance soil fertility.
- Saprophytes: A subset of nonpathogenic bacteria that feed on dead matter without causing disease.
- Pathogenic Bacteria: Organisms that are harmful and capable of causing diseases in plants and animals.
- Parasites: Bacteria that require living hosts for growth and reproduction.
Bacterial Shapes
- Cocci: Round-shaped bacteria that can exist individually or in groups.
- Staphylococci: Cluster-forming cocci that cause abscesses and boils.
- Streptococci: Chain-forming cocci responsible for infections like strep throat.
- Diplococci: Grow in pairs and can lead to pneumonia.
- Bacilli: Rod-shaped bacteria that are prevalent and associated with conditions such as tetanus, typhoid fever, and tuberculosis.
- Spirilla: Curved or corkscrew-shaped bacteria; Treponema pallidum causes syphilis.
Bacterial Movement
- Flagella or Cilia: Hairlike projections that enable bacteria to move; they use a whip-like motion to propel themselves through liquid.
Infections
- Local Infection: Limited to a specific area, such as a pimple or infected cut.
- General Infection: Occurs when pathogenic bacteria and their toxins enter the bloodstream, leading to widespread conditions like blood poisoning.
Disease Transmission
- Contagious Diseases: Spread through direct or indirect contact, including airborne transmission (coughing, sneezing) and contaminated objects (dirty hands, common towels).
Viruses and Fungi
- Filterable Viruses: Extremely small organisms that pass through fine filters, not visible under a microscope.
- Plant Parasites/Fungi: Cause contagious diseases like ringworm and can affect nails.
Immunity
- Immunity refers to the body’s ability to resist infections and effectively eliminate bacteria that invade.
