Answers
Answer:
A pathogen brings disease to its host. Another name for a pathogen is an infectious agent, as they cause infections. As with any organism, pathogens prioritize survival and reproduction.
Explanation:
Viruses
Viruses are made up of a piece of genetic code, such as DNA or RNA, and protected by a coating of protein. Once you’re infected, viruses invade host cells within your body. They then use the components of the host cell to replicate, producing more viruses.
After the replication cycle is complete, these new viruses are released from the host cell. This usually damages or destroys the infected cells.
Some viruses can remain dormant for a time before multiplying again. When this happens, a person appears to have recovered from the viral infection, but gets sick again.
Antibiotics do not kill viruses and therefore are ineffective as a treatment for viral infections. Antiviral medications can sometimes be used, depending on the virus.
Bacteria
Bacteria are microorganisms made of a single cell. They are very diverse, have a variety of shapes and features, and have the ability to live in just about any environment, including in and on your body. Not all bacteria cause infections. Those that can are called pathogenic bacteria.
Fungi
There are millions of different fungal species on Earth. Just 300Trusted Source or so are known to cause sickness. Fungi can be found just about everywhere in the environment, including indoors, outdoors, and on human skin. They cause infection when they overgrow.
Parasites
Parasites are organisms that behave like tiny animals, living in or on a host and feeding from or at the expense of the host. Though parasitic infections are more common in tropical and subtropical regions, they can occur anywhere.
