Intro to Cells

Bacteroids Thetaiotaomicron

Predominant intestinal bacteria that produces enzymes that break down the plant material that we ingest.
i.e. oat fibres 

Eukaryotic Cells 

Cells with a nucleus that contains most of the genetic material
e.g neurons, muscle cells, skin cells.

Microbiome

• this describes the population of microbiotic organisms within the human body.

• such communities or microroganisms is general are not visible to the human eye.

Prokaryotic Cells

cells that do not contain a nucleus 
e.g bacterial cells - no membrane-bound DNA
- Human body contains more prokaryotic cells than eukaryotic cells (10 times more!)
- Prok. cells make up 2-3% body mass
- Mostly harmless: carry out essential functions in physiological systems
- If harmful: managed by immune system

Staphylococcus Haemolyticus 

• Harmless when resideing on the skin, which is what it ussually does.

• Harmful if it enters the human body -> becomes pathogen -> causes immune system to become active

Streptococcus Salivarius 

• one of the first microbes to colonize a newborn's oral cavity and gastrointestinal tract.

• inhabitant of the upper respiratory tract and oral cavity.

• contributes to formation of dental plaque.
