A ____ is an agent that can cause infections and diseases.
Darina [25.2K]

<em>A </em><em>virus </em><em>is an agent that causes infections and diseases. </em>

<h2>Further Explanation </h2>

Viruses are microscopic parasites that infect cells of biological organisms. Viruses are obligate parasites, this is because viruses can only reproduce in living material by invading and utilizing the cells of living things because viruses do not have cellular equipment to reproduce themselves.

The term virus usually refers to particles that infect eukaryote cells (multicellular organisms and many types of single-cell organisms), while the term bacteriophage or phage is used for types that attack types of prokaryotic cells (bacteria and other organisms that do not cell nucleated).

The virus has been infecting since the days before Christ, this is evidenced by the existence of several discoveries, namely reports of virus infections in hieroglyphics in Memphis, the capital of ancient Egypt (1400 BC) which shows the existence of poliomyelitis. In addition, King Pharaoh Ramses V died in 1196 BC and is believed to have died of the smallpox virus.

In 1880, Louis Pasteur and Robert Koch put forward a "germ theory" namely that microorganisms are the cause of disease. At that time also the famous Koch Postulate which is very well known today, namely:

  • A disease agent must be present in every case of the disease
  • The agent must be isolated from the host and can be grown in vitro
  • When the muri agent culture is inoculated into susceptible healthy host cells, it can cause disease
  • The same agent can be taken and re-isolated from the infected host

<h3>Various kinds of viral infections </h3>
  • Acute infections are infections that last for a short time but can also be fatal.
  • Chronic infection is a prolonged viral infection so there is a risk of symptoms of the disease coming back.

(Ch. 27.4) Many people are allergic to substances in the environment, such as ragweed pollen, as well as foods, such as peanuts.
djverab [1.8K]

Answer:

C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response.

Explanation:

When a person is allergic to a substance, his or her immune system recognizes a harmless substance, such as components in food, pollen, or dust, as a treat. As a consequence, it starts an immune response that leads to inflammation. The substance that starts the allergic reaction is called an allergen, and it is not a pathogen because it is not a real threat to the body since it does not infect cells. When the allergen enters the body, it binds to antibodies that are in contact with a special type of cell. These specific cells will release a substance known as histamine. Histamine will produce an inflammatory reaction affecting different tissues in our body. For example, it can make us sneeze, have a running nose, swelling parts of our body, have itchiness and redness, amongst others.
