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.
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.
Bacteriophages are viruses that infect bacteria. They don't infect our cells, but they're found in bacteria living in our gut. Here they may affect our lives.
Learn the different groups of protozoans, as well as characteristics, structure, examples, and images of the different types. This article also includes informative videos about the different diseases brought about by parasitic protozoans.
Throughout the world there exists numerous viruses and diseases capable of inflicting serious harm (or death) on the human population at large. This article explores the 10 deadliest and most dangerous viruses known to currently exist in the world.
Social amoebas are also known as cellular slime molds and dictyostelids. They start life as ameboid cells but join to form a multicellular grex or slug when food is scarce.
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.
Staphylococcus epidermidis is a bacterium found on skin and mucous membranes. It's often harmless, but some strains have become resistant to antibiotics and may be dangerous.
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.
Stentor is an interesting, single-celled predator. At least one species makes relatively complex decisions. Studying it may help scientists understand the behavior of our cells.
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.
Planarians are flatworms with an amazing ability to regenerate. Scientists are investigating this ability and hope to apply their discoveries to human biology.
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.
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.
Researches have discovered evidence showing that complex life may have first evolved in lakes, rather than in oceans as was previously believed.
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.
