Mircobiology

Infections in humans and animals can be caused by various microorganisms, including viruses, bacteria, protozoans, and fungi. Viruses can infect different hosts, such as plants, bacteria, and humans, leading to diseases like AIDS, influenza, chickenpox, and the common cold.

 Mircobiology

Virus caused disease

Caused by a virus infecting cells

Some viruses only infect bacteria
called Phages
Some viruses only infect humans
AIDS
The Common Cold
Chickenpox
The Flu

Caused by Influenza Virus

Some viruses only infect plants

Anti-Fungal Agents

Used to treat fungal infections

Molaria

Spread by Mosquitos

Parasites

Diseases in humans and other animals

Giardiasis
Disease in humans caused by a protozoan

Invloves formation of cysts

In cyst form, protozoan is protected and can be spread in air and water

Defences of the Immune System

Fever

Immune cells and proteins

Inflammation

Resident micro-organisms

Physical & Chemical Barriers

Communicable Diseases

Infections transmitted from one person to another

Indirect Transmisson
Direct Transmisson

"Good" Bacteria

Not all bacteria are harmful but instead keep us healthy.

Digestive tract bacteria

Skin Bacteria

Antibioics

Treats Bacterial Infection

Infection

Developing of Infection

5. Exiting Host
4. Causing Damage (disease)
3. Surviving Host Defences
2. Attaching Firmly
1. Finding portal of entry

Eveloped Virus

Naked Virus

Viruses

Viruses are not considered cells, and they cannot multiply without a host cell.


They are often called biological agents or particles.



Virus Multiplication

Six Step Process
6. Release
5. Assembly
4. Synthesis
3. Uncoating
2. Penetration
1. Adsorbtion

Capsid

Possible Extra Outer Layer
Centeral Core

Genetic Material

RNA or DNA

Spore Formation

Sporangia

Produces Spores

Budding

Sexual Reproduction

Chlamydomonas

Mitosis

Binary Fisson

Protist

Animal-like protist

Protozoa
Sporozoan
Flagellate
Rhizopod
Ciliate

Plant-like Protist

Alga
Green algae
Euglenoids
Diatoms
Dinoflagellates

Conjunction

Asexual Reproduction

Prokaryotic Cell

Prokaryotic cells do not have a nucleus, but they do have ribsosomes, a cell membrane and chromosomal DNA. Many have a cell wall, plasmid DNA, pili and flagellum.

They are single celled organisms.


Spirilli

Spiral Shaped

Bacilli

Rod Shaped

Cocci

Circular Shaped

Mircobiology

"A field of biology that studies organisms that are too small to be seen with the unaided eye."


All life on earth can be classified into three groups called domains.

Archaea, Bacteria, and Eukarya. These groups can be further classified into kingdoms.


Although Viruses are not cells and are not considered micro-organisms, they are instead called particles or biological agents.

A microorganism is an organism so small that people cannot see them with the naked eye.

Microorganisms can be harmful and useful organisms.

Eukarya

Eukarya is one of the three groups (domains) that make up microbiology.

It can be further classified into its own kingdom, called Eukarya. The kingdom is made up of four more groups which are plants, animals, fungi, and Protista.

Eukaryotic Cell

Eukaryotic cells do have a nucleus, as well as ribsosomes, a cell membrane and chromosomal DNA. Many have a cell wall, plasmid DNA, pili and flagellum.

They are single celled organisms.

Protista
Fungi

Yeasts

Moulds

Animals
Plants

Archaea

Archaea is one of the three groups (domains) that make up microbiology.

It can be further classified into its own kingdom which is simply called Archaea.

Harmful microorganisms include fungi, bacteria, protozoa, etc.

They cause several diseases in human beings, animals, and plants, which can even lead to death.

The harmful microorganisms not only can damage the human body, but also the food we eat.

Thermophiles

What diseases can they cause?

Methogens

Give examples of how the spread of harmful organisms can be prevented.

Halophiles

Give examples of how harmful organisms can spread.

Bacteria

Bacteria is one of the three groups (domains) that make up microbiology.

It can be further classified into its own kingdom which is simply called Bacteria.

Research about the main characteristics of the microorganisms and give examples!

Proteobacteria
Spirochetes
Chlamydia
Cynobacteria
Gram Positive
