What Is the Difference Between Good Bacteria & Bad Bacteria?

Video of the Day

Identification

Bacteria are single-celled living things that are neither plants nor animals and have their own biologic classification called prokaryotes An outer cell wall and plasma membrane surrounds their one cell but they have no internal organelles bound by membranes, according to Arthur Vander, James Sherman and Dorothy Luciano in ‚ÄúHuman Physiology‚ÄĚ

Thousands of species of bacteria are found in the soil, water and on dust particles in the air Some bacteria can damage tissues or release toxins that enter the blood and disrupt physiological functions Other bacteria can perform useful functions for the human body

Good Bacteria

Certain bacteria are safe in food and actually produce its desired taste and texture For instance, bacteria are commonly used in dairy products such as yogurt and fermented milkIn many ways, bacteria help to sustain life for humans. Fermented milk products help people with lactose intolerance digest dairy products that otherwise would cause cramps and diarrhea The different flavor of fermented dairy products is due to the bacteria used to make them

Some bacteria, such as Lactobacillus rhamnosus, have been shown to enhance the immune system by regulation and stimulation, according to Philip Calder, Catherine Field and Harsharnjit Gill in ‚ÄúNutrition and Immune Function‚ÄĚ They also may form a barrier to help protect us from bad bacteria by altering the pH or acidity level or by releasing toxins that harm the bad bacteria

Bad Bacteria

Pathogenic or bad bacteria produce results ranging in severity from food poisoning or toothache to death, according to the Virtual Museum of Bacteria Some bacteria such as salmonella may cause a brief bout with stomachache or diarrhea and may in some cases lead to death Others cause diseases such as anthrax that are so severe they have been used by bioterrorists

Food-borne Illnesses

The Food and Drug Administration, monitors the US food supply and sets safety standards The leading food safety concern, according to the FDA, is food-borne illness The Centers for Disease Control and Prevention, estimates that 76 million people experience food-borne illness each year in the US, as reported by Eleanor Whitney and Sharon Rolfes in ‚ÄúUnderstanding Nutrition‚ÄĚ

The very old, very young, pregnant women, sick or malnourished people and people with weakened immune systems prove most vulnerable to food-borne illness

Significance

Most bacteria are harmless to humans and some are beneficial Mutually beneficial or symbiotic bacteria not only help you with digestion but also help produce vitamins and protect you against bad bacteria When you take antibiotics for illness, both bad and good bacteria are killed Your cure is not complete until your friendly bacteria are replaced

Other benefits of bacteria include decomposing dead plants and animals, producing oxygen, controlling plant pests and making nitrogen from the air available as food for plants that produce essential nutrients for humans In many ways, bacteria help to sustain life for humans
