Lecture 1Microbial World And You

Dr. Dalia Mohsen Associate professor of microbiology.

what is microbiology microbiology is the study of microorganisms
What is Microbiology?Microbiology is the study of microorganisms.

Micro - too small to be seen with the naked eye (cannot seen by naked eye).

Bio - life

ology - study of

What are Microorganisms?

Also called as Microbes are minute living things that individually are usually too small to be seen with the unaided eye.

An organism that can be seen only with the aid of a microscope.

Dr. Dalia Mohsen Associate professor of microbiology.

characteristics of cell
Characteristics of cell

Maintain structure by taking up chemicals and energy from the environment

Respond to stimuli in the external environment

Reproduce and pass on their organization to their offspring

Evolve and adapt to the environment

microorganisms what comes to mind
Microorganisms - what comes to mind?

Diseases

Infections

Epidemics

Food Spoilage

Only 1% of all known bacteria cause human diseases

About 4% of all known bacteria cause plant diseases

95% of known bacteria are non-pathogens

Dr. Dalia Mohsen Associate professor of microbiology.

Microorganisms are found everywhere in the world, in all living things, plants and animal, on and inside your body, than there are cells that make up your entire body.
  • Microorganisms can live in the air, on land, and in fresh or salt water environments.
  • Some of them are pathogens, can be harmful and causes diseases, but majority of microorganisms beneficial for us.

Dr. Dalia Mohsen Associate professor of microbiology.

types of microorganisms
Types of Microorganisms
  • Bacteria are unicellular organisms. Because they have no nucleus, the cells are described as prokaryotic.
  • Archaea (Archae Bacteria) have prokaryotic cells; lack peptidoglycan in their cell walls. Archaea include methanogens, halophiles, and extreme thermophiles.

extreme thermophiles

3. Fungi (mushroom, molds, and yeasts) have eukaryotic cells (with a true nucleus). Most fungi are multicellular. Fungi obtain nutrients by absorbing organic material from their environment.

4. Protozoa are unicellular eukaryotes. Protozoa obtain nourishment by absorption or ingestion through specialized structures.

Dr. Dalia Mohsen Associate professor of microbiology.

slide11
5. Algae are unicellular or multicellular eukaryotes that obtain nourishment by photosynthesis. Algae produce oxygen and carbohydrates used by other organisms.

6. Viruses are non cellular entities that are parasites of cells. Viruses consist of a nucleic acid core (DNA or RNA) surrounded by a protein coat
