Microbiology - Lecture Thirty : The Human Microbiome

3 important questions on Microbiology - Lecture Thirty : The Human Microbiome

What are the goals of the human microbiome project ?

A microbiome is the complete collection of microorganisms and their genes within a particular environment.
  • To develop a reference set of microbial genome sequences and to perform preliminary characteristization of the human microbiome
  • To explore the relationship between disease and changes in the human microbiome
  • To develop new technologies and tools for computational analysis
  • To establish a resource repository
  • To study the ethical, legal and social implications of human microbiome research

What are some examples of the human gut microflora ?

Different species specialize in different parts of the body
  • With High diversity and variety of species in each habitat
  • Reflects how different sites are very different in conditions
Between different individuals we have different variations, like the microbial signature
  • High density of microbes live in the GI tract
  • Mostly in faeces, 50% of biomass is of bacteria
  • The 4 main groups of gut microbiota:
- Firmicutes
- Bacterioidetes
- Actinobacteria
- Proteobacteria

How can our microbiome influence us ?

  • All the microbes in us are competing with each other. If we have more good bacteria in us it is more difficult for bad bacteria to grow. THIS IS USEFUL.
  • Fecal matter transplants from a healthy person can replace depleted good bacteria in a sick patient. These are used for recurrent Clostridium difficile infections.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
