Bacteria viruses and fungi worksheet

Vaccines give preemptive protection from certain viruses by training the body's immune system to recognize and attack a specific virus. Common forms: Bacteria cause food poisoning, strep throat and urinary tract infections , as well as infections such as tuberculosis.

Bacteria are bigger and more complex than viruses, though they can still spread through the air. A bacterium is a single cell, and it can live and reproduce almost anywhere on its own: in soil, in water and in our bodies. For the most part, we live peacefully with bacteria—the colonies in our guts are helpful to us and strengthen our immune system. But like viruses, bacteria can also harm us by replicating quickly in our bodies, killing cells. Some bacteria also produce toxins which can kill cells and cause an outsized, damaging immune reaction.

Broad-spectrum antibiotics were developed to kill bacteria in our bodies and in the food supply by inhibiting their growth. But bacteria are extremely adaptive and can quickly evolve to evade antibiotics. Bacteria share their antibiotic-resistant genes with each other, meaning more strains generate resistance to the drugs we use. Common forms: Fungi are responsible for causing conditions such as yeast infections , valley fever and meningitis.

Fungi are more complicated organisms than viruses and bacteria—they are "eukaryotes," which means they have cells. Of the three pathogens, fungi are most similar to animals in their structure. There are two main types of fungi: environmental, which are yeast and mold that often live in soil and don't generally cause infection in most healthy people; and commensals, which live on and in us and generally don't hurt us.

Certain environmental fungi reproduce "spores," particles that can enter our body through the lungs or on the skin. These fungi can be especially damaging for people with weakened immune systems, as the fungi can spread quickly and damage many organs.

Fungi are slower to mutate, so they are easier to target with antifungal medications than bacteria are with antibiotics. Skip to content.
