There are many different antibiotics, each of which exerts a different type of inhibitory effect, which is affected by the type of bacteria. Bacterial cells are prokaryotic; primitive cells that differ significantly from eukaryotic cells in humans. Bacteriocidal quinolones exert their effects by blocking the bacteria’s ability to make DNA (replication). Many quinolone antibiotics belong […]

Eukaryotic cells are found in every domain with the exception of the Bacteria and Archea domain. Eukaryotic cells differ from prokaryotic cells in two major ways; size, and the presence of a membrane surrounding the nucleus, and other organelles. Because eukaryotic cells are so much larger than prokaryotic cells (roughly ten times larger) it becomes […]

There are many different antibiotics, each of which exerts a different type of inhibitory effect, which is affected by the type of bacteria. Bacterial cells are prokaryotic; primitive cells that differ significantly from eukaryotic cells in humans. Sulfa antibiotic drugs work by inhibiting a metabolic pathway that is necessary for DNA synthesis. Each article in […]

Viruses are curious things in nature. They are so bizarre that some scientists doubt they even fit the qualifications of a living thing. However, they are so pervasive in nature and our everyday lives that they are still vastly important alive or not alive. Virus reproduction is one of the most interesting features of these […]

There are many different classes of antibiotics each exerting a different type of inhibitory effect that specifically impact bacteria. Bacterial cells are prokaryotic; primitive cells that differ significantly from humans’ eukaryotic cells. Antibiotic cephalosporins work by inhibiting the synthesis of the bacteria cell wall. Each article in this series covers a specific class of antibiotic […]
A cell is one of the most rudimentary elements of any living organism. Each part of the human body contains specific types of cells that help it function properly. These types of cells form functional tissues, tissue organs, organs, organs that function as systems, and functional systems that form a living organism. Some organisms are […]

Bacteria and viruses are often lumped together into a general category of “bad things that can cause infection”. But these two types of infectious agents are very different, and the differences are important to your health. What Is a Cell? Bacteria are living single celled creatures. In contrast, viruses are not alive. So to clearly […]

For some reason students rarely seem to get excited about cell biology, a class that is typically required for anyone entering into the field of health care. In the cell biology course that I teach, to help perk up interest in the cellular world, I start the semester off with a little story about why […]
