Types of Microorganisms
In a 2014 review article, "Analyzing the Human Microbiome: A 'How To' Guide for Physicians," in the American Journal of Gastroenterology, the authors mention that gut bacteria and other microorganisms aid in digestion, stave off colonization by harmful pathogens, and help in the development of the immune system.
Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes.
What are Bacteria, Yeasts & Molds? 4 University of Georgia Cooperative Extension Bulletin 817 Bacteria Bacteria make up the largest group of microorganisms. People often think of them only as germs and the harm they do. Actually, only a small number of bacteria types are pathogenic (disease causing). Most are harmless and many are helpful.
Bacteria, yeasts and molds are three types of microorganisms. Some people often confuse, and almost always misunderstand, their functions, but they are just as real and alive as you are.
Bacteria are microscopic single-celled organisms that thrive in diverse environments. They can live within soil, in the ocean and inside the human gut. Humans' relationship with bacteria is complex. Sometimes they lend a helping hand, by curdling milk into yogurt, or helping with our digestion.
Salmonella (genus Salmonella), group of rod-shaped, gram-negative, facultatively anaerobic bacteria in the family Enterobacteriaceae. Their principal habitat is the intestinal tract of humans and other animals.
Let us understand what virus and bacteria really are. What is Virus? Viruses are extremely small substances made of nucleic acids (RNA – ribonucleic acid or DNA – deoxyribonucleic acid) and proteins, which can only be seen through an electron microscope.
Difference between Virus and Bacteria? Virus is an infective agent made of nucleic acids and proteins. Bacteria is a unicellular organism (a single cell).
Get answers to frequently asked questions about Campylobacter Campylobacter causes an estimated 1.3 million illnesses each year in the United States. Most illnesses likely occur due to eating raw or undercooked poultry, or to eating something that touched it. Some are due to contaminated water, contact with animals, or drinking raw (unpasteurized) milk.
Clostridium perfringens (C. perfringens) is a spore-forming gram-positive bacterium that is found in many environmental sources as well as in the intestines of humans and animals. C. perfringens is commonly found on raw meat and poultry.
Protozoa are a diverse group of organisms that are non-phototrophic, unicellular, eukaryotic microorganisms with no cell walls. In general, protozoa have different stages in their lifecycles. Trophozoite is the active, reproductive, and feeding stage.
Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes.

E. coli is a type of bacteria that normally live in the intestines of people and animals. However, some types of E. coli, particularly E. coli O157:H7, can cause intestinal infection. E. coli O157:H7 and other strains that cause intestinal sickness are called Shiga toxin–producing E. coli (STEC) after the toxin that they produce.

About Microbiology Micro-organisms affect every aspect of life on Earth. Some microbes cause disease but the majority are completely harmless. Some microbes cause disease but the majority are completely harmless.
Fungi, singular, fungus, is a group of eukaryotic, non-phototrophic organisms with rigid cell walls, that includes mushrooms, molds and yeasts. This definition has some words in it that probably need definitions of their own.
Listeriosis is a serious infection caused by the germ Listeria monocytogenes. People usually become ill with listeriosis after eating contaminated food. The disease primarily affects pregnant women, newborns, older adults, and people with weakened immune systems.
Listeria can cause fever and diarrhea similar to other foodborne germs, but this type of Listeria infection is rarely diagnosed. Symptoms in people with invasive listeriosis, meaning the bacteria has spread beyond the gut, depend on whether the person is pregnant.

Microorganisms [microbes] include bacteria, fungi, protozoa, some algae, viruses, viroids and also prions that are proteinacious infectious agents. Viruses reproduce only inside the cells of the host organism, which may be a bacterium, plant or animal.
Protozoa are a diverse group of organisms that are non-phototrophic, unicellular, eukaryotic microorganisms with no cell walls. In general, protozoa have different stages in their lifecycles. Trophozoite is the active, reproductive, and feeding stage.
Protozoa are single-celled microorganisms that get their food from the surrounding enviroments, or as scientists would say say «They are heterotrphs. They can be found in a veriety of habitats such as freshwater (including ponds and rivers), marine (the sea) and even in the soil.
Salmonella is a bacteria that makes people sick. It was discovered by an American scientist named Dr. Salmon, and has been known to cause illness for over 125 years. The illness people get from a Salmonella infection is called salmonellosis.
Viruses are the smallest and simplest life form known. They are 10 to 100 times smaller than bacteria.; The biggest difference between viruses and bacteria is that viruses must have a living host - like a plant or animal - to multiply, while most bacteria can grow on non-living surfaces.
Antibiotics cannot kill viruses, but can kill most bacteria, with the exception of most Gram-negative bacteria. An example of a disease caused by bacteria is strep throat and an example of an affliction caused by a virus is the flu.
