Cryptosporidiosis is a diarrheal disease caused by microscopic parasites of the genus Cryptosporidium.
He saw them everywhere: microscopic swarms of bacteria, parasites and viruses on every surface, infecting his body with untold horrors. The parasite is protected by an outer shell that allows it to survive outside the body for long periods of time and makes it very resistant to chlorine disinfection.While this parasite can be transmitted in several different ways, water is a common method of transmission and Cryptosporidium is one of the most frequent causes of waterborne disease (drinking water and recreational water) among humans in the United States.
A close look at even the healthiest patch of human skin would reveal a rich diversity of microbial life, including some bugs with the potential to do great physical harm.A microbe is any single-celled organism, whether plant, animal, fungus or bacterium. Viruses are usually considered microbes, even though they aren’t cells themselves, but rather bundles of RNA that invade and hijack healthy cells. Scientists divide microbes into four broad categories: bacteria, protozoa, fungi and viruses. If a microbe has the ability to make us sick (pathogenic), like some bacteria and most viruses and protozoa, we call it a germ.Of those hundreds of trillions of microbes living on or inside your body, a significant percentage of them are germs.
The good news is that germs typically exist in small enough quantities that the immune system can neutralize them before they cause disease. Sometimes, however, germ colonies breach our defences and flourish.The definition of disease is when cells in your body stop functioning properly.
One of the many causes of disease is infection, when a germ enters the body (through the digestive, respiratory or circulatory systems), multiplies rapidly and begins to inhibit normal cell function. Some protozoa like the malaria parasite colonise red blood cells and rupture them, leading to severe anaemia, while some bacteria like E coli emit toxins that destroy cells along the intestinal or urinary tracts.

Life itself began four billion years ago as a form of bacteria, and it was an ancient type of cyanobacteria that was the first to perform the magic act of photosynthesis, turning sunlight into oxygen. Even today, microbes are the miniature factories that regulate and recycle the essential building blocks of life.
When an organism dies, its carbon is salvaged and recycled into the environment by a host of microbes, including bacteria and fungi.
Phytoplankton, composed of both protozoa and cyanobacteria, transform C02 into solid, reusable carbon compounds. And bacteria in our intestines, notably lactobacillus acidophilus, help us better digest and extract nutrients from food.Unfortunately, the few seriously nasty microbes give the rest a bad name. Infectious disease caused by microbial infections kills more people worldwide than any other single cause. Just think of the diseases that can trace their roots to a viral, protozoan or bacterial infection: HIV, TB, malaria, pneumonia, sleeping sickness and historical pandemics like the bubonic plague, Spanish flu and smallpox. The best protection is to keep your hands clean with soap and water and to keep your hands away from your face.
Get all of your vaccinations and vaccinate your children (a surprising number of adults die from chicken pox every year, usually contracted by their unvaccinated child). Take these simple everyday precautions and your well-evolved immune system should take care of the rest.Types of germsBacteriaBacteria are some of the smallest and oldest life on Earth. Fossil evidence of these single-cell organisms dates back 3.5 billion years and may represent some of the first life on the planet.

Bacteria live everywhere and can thrive in the most extreme cold and heat, but they love the warm comfort of the human body. Only one per cent of known bacteria are harmful to humans, but we know a few of them too well: strep throat, E coli, botulism, the list goes on. Strains of bacteria in the mouth, such as lactobacillus acidophilus, feed on sugars and release lactic acid. Most fungi exist as microscopic networks of cells, but their colonies can grow so large that we can see them with the naked eye: on the surface of spoiling food, rotting logs, or as the large fruiting bodies we call mushrooms. If left unchecked, colonies will grow rapidly, causing irritation and inflammation of the skin underneath. Once the cyst reaches the intestinal tract, it releases trophozoites, active amoeba that burrow into the intestinal lining, causing violent diarrhoea and sometimes even death.VirusesViruses are the smallest germs of all.
The virus then injects molecules of DNA or RNA into the cell, which directs the cell to produce even more virus particles before destroying itself. In most healthy children, the body’s immune system fights off the virus, often causing fevers and body aches in addition to the trademark itchy pox.
