Nonpathogens
Microbes that do not produce disease •not harmful
Nonpathogens are microorganisms that do not cause any harm or diseases to humans or animals. These microorganisms can be found everywhere in our environment, including soil, water, air, and even on our skin and in our digestive tract.
Examples of nonpathogenic microorganisms include:
1. Lactobacillus – a type of bacteria that is commonly found in the gastrointestinal tract and is involved in the digestion of food.
2. Saccharomyces – a type of yeast that is used in the production of bread and beer.
3. Streptomyces – a type of bacteria that is commonly found in soil and is used in the production of antibiotics.
4. Bacillus subtilis – a type of bacteria that is commonly found in soil and is used in the production of enzymes and amino acids.
5. Pseudomonas – a type of bacteria found in soil and water, and used in the production of biodegradable plastics.
While nonpathogenic microorganisms do not cause diseases, some may still have negative effects on human health. For example, some nonpathogenic bacteria can cause infections in people with weakened immune systems. Therefore, it is important to practice good hygiene and appropriate safety measures in handling these microorganisms.
