Microbiology

Antibiotic resistance in bacteria that cause disease is a serious problem. Soil contains many bacteria, some of which may help us by making new antibiotics.

Staphylococcus epidermidis is a bacterium found on skin and mucous membranes. It's often harmless, but some strains have become resistant to antibiotics and are potentially dangerous.

Planarians are flatworms with an amazing ability to regenerate. Scientists are investigating this ability and hope to apply their discoveries to human biology.

Klebsiella pneumoniae is a bacterium that can live in our body and is sometimes dangerous. It's usually harmless in the digestive tract, but this may not always be true.

Saprolegnia and Phytophthora are examples of oomycetes or water molds. Some species of Saprolegnia kill fish. One species of Phytophthora was responsible for the nineteenth-century potato famine in Ireland.

Social amoebas are also known as cellular slime molds and dictyostelids. They start life as separate ameboid cells but join to form a multicellular grex or slug when food is scarce. The grex has some interesting abilities.

Antibiotics interfere with vital activities in bacteria by various methods. Unfortunately, microbes are becoming resistant to the drugs. Arylomycins may be helpful in this situation.

Bacteria have some amazing abilities. They can live in extreme habitats, produce light or electricity, communicate with each other, and act as predators and magnets.

Investigative skills play an important part in learning practical biology. Experiments are important in the scientific method. This article teaches good experimental design for young biologists.

Acanthamoeba is a microscopic, single-celled organism that can infect the cornea of the eye. It causes a disorder called Acanthamoeba keratitis, which is most common in contact lens users.

Immunology is the complex study of the immune system and its associated functions. Immunity is how the body attempts to prevent disease. This article will briefly discuss the types of immunity, vaccines, problems with the immune system, and more.

What causes one person to have clear skin and another person to have severe, cystic acne? Discover the genetics behind the development of this skin condition, in addition to understanding how different treatment options work.

This article is an in-depth review of cells. Meant to help high school and college students gain a better understanding of this chapter of biology.

Bacteria in the genus Yersinia have major effects on our lives. One species causes bubonic, septicemic, and pneumonic plague. Others cause foodborne illness. One may eventually help to treat cancer.

Plasmodium vivax is often said to be a less serious cause of malaria than P. falciparum, but it can be deadly. It may become dormant in the liver and later become active.

Researches have discovered evidence showing that complex life may have first evolved in lakes, rather than in oceans as was previously believed.
