Where is Bacteria found?
On or in just about every material and environment on Earth.
What are fungi?
Any of a group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools
What is a Virus?
A submicroscopic infectious agent that replicates only inside the living cells of an organism
What is agar?
A solution that enhances the growth of bacteria.
Tiny living things that are found all around us and are too small to be seen by the naked eye.
Microbe
List three diseases Fungi can cause from our PowerPoint:
Athlete's foot
Ringworm
Yeast infections
Most biologists consider viruses to be_________ because they don’t exhibit all the criteria for life
nonliving
Three main areas of Pathology from our PowerPoint?
1. Bacteria
2. Fungi
3. Viruses
List three benefits of Bacteria from our PowerPoint:
Making drugs, such as antibiotics and vaccines.
Making biogas, such as methane.
Cleaning up oil spills and toxic wastes.
Killing plant pests.
Transferring normal genes to human cells in gene therapy.
Fermenting foods
List three Benefits of Fungi
The majority of grasses and trees require a mycorrhizal relationship with fungi to survive.
Yeasts have been used for thousands of years in the production of beer, wine, and bread.
Fungi not only directly produce substances that humans use as medicine, but they are also versatile tools in the vast field of medical research.
Some fungi attack insects and, therefore, can be used as natural pesticides.
A cell in which a virus replicates is called the____
host cell
List three portals of exit from our PowerPoint
By coughing or sneezing
Through removal of blood
By an insect bite
In the feces
Through an open lesion
In the urine
Bacteria are classified into four groups according to their basic shapes. Can you name them?
Spherical (cocci)
Rod (bacilli)
Spiral (spirilla)
Comma (vibrios)
List four Examples of Fungi from our PowerPoint:
Mushrooms
Toothed Fungus
Puffball
Yeast
Mold
What are the two Viral Replication Cycles from our PowerPoint?
Lytic cycle
Lysogenic cycle
List three disease categories from our PowerPoint
Food and Water borne - pathogen is in a food or water source
Blood Borne - carried in blood or other bodily fluids
Zoonotic - carried by animals
Airborne - carried by the air, often affect respiratory tract
List at least five parts of the structure of Bacteria and their functions.
Cell wall
Protects and gives shape
Outer Membrane
Protects against antibodies
Cell Membrane
Regulates movement of materials, contains enzymes important to cellular respiration
Cytoplasm
Contains DNA, ribosomes, essential compounds
Chromosome
Carries genetic information. It is circular
Plasmid
Contains some genes obtained through recombination
Capsule & Slime Layer
Protects the cell and assist in attaching cell to other surfaces
Endospore
Protects cell against harsh environments
Pilus
Assists the cell in attaching to other surfaces
Flagellum
Moves the cell
What popular Medicine comes from Fungi?
Penicillin
How are viruses named?
the diseases they cause
or the organ or tissue they infect
Today, most viruses are given a genus name ending in the word “virus” and a species name
