Two new articles are now available describing a simple experiment that can be done to examine how well mouthwash works to kill oral bacteria. The experiment compares alcohol and non-alcohol mouthwashes as well as time spent rinsing the mouth.
This experiment can be found in the new Suite101 articles:
For a Word document of this experiment, go to the Science Prof Online Virtual Cell Biology Classroom. The lecture page on prokaryotic cells contains a link called Mouthwash Experiment on Controlling Oral Bacteria. This link will allow you to download the document.
Geek out and have fun!

The Virtual Microbiology Classroom offers both free lecture and lab material from an introductory-level college microbiology course.
Virtual Microbiology Lab exercises and PowerPoint topics include:
- Basic Microscopy
- Bacterial Growth Media and Culture
- Differential Staining (Gram, Acid-fast and Endospore)
- Bacterial Control (Heat, UV, Antibiotics and Chemical Disinfectants)
The site also provides free images of lab materials and procedures, including:
- Bacteria: Smears, Heat-fixing & Staining
- Bacterial Colonies
- Bacterial Growth Media
- Compound Microscope

I have been slowly but steadily adding a number of microscopy articles to the Microbiology topic at Suite101.
If you are a Cell Biology or Microbiology student first learning to use a scope of trying to re-familiarize yourself with the basic concepts of microscopy, the following articles should help get off to a good start:
Suite101 Microscopy Articles
- What Is a Compound Light Microscope?
- Focusing and Finding Objects with a Light Microscope
- Viewing Bacteria under Oil Immersion
- Preparing a Microscope Slide of Bacteria

There are many recognized virally-mediated exanthems. This article series covers some of those most commonly encountered during childhood, including those caused by DNA viruses (chickenpox, erythemia infectiosum, roseola) and those caused by RNA viruses (rubella and rubeola).
