Parasites are usually larger than bacteria, although some environmentally resistant forms are nearly as small. Some parasites only replicate within a host organism, but some can multiply freely in the environment.
Parasites can be made of one cell, as in the case of Giardia , or many cells, as with parasitic worms. In developing countries unicellular parasites, such as Plasomdium , the cause of malaria, are a major sources of disease. Waterborne parasites, such as Giardia and Cryptosporidium are the most common causes of parasitic disease in the United States. Fungi are diverse in terms of their shape, size and means of infecting humans.
Fungi are eukaryotes, meaning that like parasites, their cells have a true nucleus and complex internal structures. They are most commonly found as environmentally resistant spores and molds, but can cause disease in humans in the form of yeasts. Fungi most often cause skin infections and pneumonia.
Here we can compare a human hair to the scale of fungi, bacteria, and viruses. Bacteria are tiny, single-celled organisms that are found almost everywhere. There are bacteria on your desk, your skin, inside you, and even on this computer screen. Most bacteria are not pathogens. This means that for the most part, they don't cause disease. This picture shows bacteria pink attacking some skin cells yellow. Bacteria are considered simple cells because they don't have a nucleus. You probably recognize a common kind of fungus, the mushroom.
They actually make up an entire kingdom of life and, while most are not harmful to humans, a few of them are pathogens. This fungus is much smaller than the mushrooms we are familiar with. You usually need a microscope to see it.
Fungi survive by getting energy from other organisms. Often, they do this by feeding on the decaying remains of plants. Similarly, many fungal pathogens feed on the nonliving outer layers of our skin. This fungi, Epidermophytom floccosum , is often responsible for athlete's foot.
Some fungi also produce toxins, called mycotoxins. The most common way for humans to be exposed to mycotoxins is by accidentally eating poisonous mushrooms. Viruses are the smallest common pathogen. They are so small in fact that many of them actually infect bacteria. They are different from other pathogens because they cannot reproduce on their own.
We call this replication. Sometimes, a virus can wait inside a cell for a long time before it starts replicating. This means that you can get sick long after you are exposed to a virus.
The Chicken Pox is an example of a common viral infection that often remains dormant, or unnoticed in the body. It remains dormant within you and can resurface to cause a condition called shingles later in life. A microscopic image of Varicella zoster , the virus that causes the chicken pox. Symptoms that include a scratchy throat and stuffy nose come on much more slowly for the cold than the flu.
With the flu, symptoms are more severe and also usually include fever and chills. Fevers tend to be higher in children than in adults.
