The amount and location of peptidoglycan in the prokaryotic cell wall is what determines whether a bacterium is Gram-positive or Gram-negative.

Penicillin is a common broad spectrum antibiotic used to treat many common infections. Though allergies can occur how safe is it to take a course of penicillin?

Heat, UV radiation, antibiotics and chemicals are all used to control bacteria, viruses and other microorganisms. How to they kill pathogens without hurting our cells?

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How does penicillin destroy bacteria without hurting our cells?

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do aminoglycosides destroy bacteria without hurting our cells?

Gram staining involves the application of a series of dyes that leaves some bacteria purple (Gram +) and others pink (Gram -). Here's how the Gram stain works.

Some bacteria have an additional layer outside of the cell wall called the glycocalyx. This coating of macromolecules protects the cell and helps it adhere to surfaces.

Most bacteria have one of these two types of cell walls. The differential Gram stain uses two dyes to distinguish between bacteria based on cell wall structure.

Gram- bacteria stain pink due to the location of cell wall peptidoglycan and an external LPS membrane. Here's how Gram staining identifies Gram negative organisms.

Most bacteria have one of these two types of cell walls. The differential Gram stain uses two dyes to distinguish between bacteria based on cell wall structure.

Antibiotics are drugs used to fight bacterial infections. How do these medications work to kill bacteria without harming human cells?

The genus Mycobacterium contains many members, few of which are pathogens. But when pathogenic, chronic diseases such as tuberculosis and Hansen's Disease may result.

Bacteria in the genus Streptococcus can be classified by species, hemolysis pattern and by their antigens, chemicals to which the human immune system reacts.

Bacterial controls are often used with differential stains as examples of typical positive and negative stain reactions; helpful references when identifying unknowns.

Antibodies circulating in the bloodstream bind to antigens that they recognize and attack them.

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do they destroy bacteria without hurting our cells?

Archaea are prokaryotes that differ from bacteria and eukaryotes enough to be assigned to their own taxonomic domain. Here is a brief introduction to Archaeans.

Gram, Acid Fast and Endospore stains; MacConkey's, Mannitol Salt, and Blood Agar media as well as the API-20 test strip all provide information to identify microbes.

Bacteriophages are a special type of virus that exclusively infects bacterial cells. Here's how they recognize, take over and ultimately kill their host bacteria.

A look at the structural components of eukaryotic and prokaryotic cells and the differences between the two types of cell.

All living things are composed of one or more cells. Unlike cells, viruses, viroids and prions are acellular, nonliving parasites that require a living host to reproduce.

Infectious disease can result of cellular organisms, such as bacteria (prokaryotes), from eukaryotes (cells like ours) or from nonliving infectious agents.

Curcumin, found in the spice turmeric, is a potent anti-inflammatory agent that reduces physical exhaustion in mice with experimental CFS.

The eukaryotic cells of plants and animals possess several critical differences from prokaryotic cells, including a nucleus and other membrane-bound organelles.

Gram + bacteria stain purple due to the chemistry and structure of their peptidoglycan cell wall. Here's how Gram staining identifies Gram-positive organisms.

It was a top secret project in many ways and ended up as a cooperative venture between England and the US. It is the story of penicillin in 1938-39 as Hitler begins WW2.

Bacteria and viruses are both tiny infectious agents with the ability to cause disease. So it is not surprising that these microbes are sometimes mistaken as the same.

Bacteriophages are a particular type of virus that infects only bacterial cells. Ultimately the virus kills its host, but sometimes it first becomes a hidden prophage.

Whether you know it or not, eukaryotic cells are the tiny units of life that make up your entire body. Read on and learn more about yourself!

Recent research shows that CFS/ME elevates expression of inflammation genes, so that even minimal exercise can seem like a marathon.

Pneumonia is an infection of the lungs typically caused by a bacteria, virus, or inhaled substances. Here is a look at some gram-negative bacterial causes.

Pneumonia is an inflammation or infection of the lungs most commonly caused by a bacteria or virus, but can also be caused by inhaling foreign substances.

Although they appear to behave as living things, viruses, viroids and prions are nonliving particles. Read on and discover more about these 'smart' parasites.

Viruses are not living cells, but efficient parasites that commandeer living cells and turn them into virus factories. Learn how these nonliving particles act so smart.
