Learn Biology: Good Bacteria vs. Bad Bacteria

Check out Bas Rutten's Liver Shot on MMA Surge: Mary Poffenroth, an adjunct professor of biology, discusses the differences between good and bad bacteri. Poffenroth discusses how both types of bacteria exist in abundance throughout the world. Without bacteria, humankind would cease to exist. Bacteria are not always bad, as good bacteria exist within the body and are critical in keeping the body healthy and functional. Bacteria are prokaryotic organisms, which do not have nuclei. exist everywhere on the planet, and thrive in various conditions. They are necessary for an ecosystem to flourish and humankind would not be able to survive without bacteria. Whether bacteria are considered "good" or "bad" is often determined by their potential harm to the environment and/or humankind. Harmful bacteria are called pathogenic bacteria, or pathogens, which either assume the form of an endotoxin or an exotoxin, and pose a threat to humans by creating bacterial infections within the body. of these pathogens include E.coli and streptococcus.?These bacterial infections can then be treated with antibiotics.?Some bacterial infections, such as meningitis and pneumonia, will ultimately result in death if the use of antibiotics is neglected. Benefits of Good Bacteria --------------------------------------------------------------------- Foods with bacteria called probiotics can aid in digestion and ease digestive upset, by making the good bacteria that resides within the human colon multiply and flourish.? Probiotics can be purchased over the counter in supplement form to add to various drinks or snacks, or can often be found in foods such as yogurt and miso. Good bacteria which reside within the human body also helps to expedite the production of essential vitamins, which keep the body healthy and fully functional. is also beneficial to the environment as it helps to recycle nutrients. Every?healthy?ecosystem relies on bacteria to maintain balance. Antibiotic Resistance --------------------------------------------------------------------- The overuse of antibiotics in treating infections can be harmful to individuals and the environment. Antibiotics can kill off the good bacteria which resides within the body that can allow bad bacteria to grow in its place. ?The misuse of antibiotics can actually cause other bacteria in the body to mutate and grow resistant to antibiotics in the future. viral infections can be confused with bacterial infections; since viral strains of infections cannot be cured with antibiotics, the misused antibiotics can actually cause other bacteria in the body to mutate and grow resistant to antibiotics in the future.? The bacteria known as MRSA ("Staphylococcus aureus"), which is most often transmitted in hospitals or health care locations, has become drug resistant in recent years, and poses a significant health risk to certain individuals.
