Viruses are coated genetic material that invade cells and use the cell's apparatus for reproduction.
Bacteria are single celled organisms. Some classify them as a separate (fourth) kingdom on the tree of life.
Fungi are multi-celled organisms that form a third Kingdom of life, along with the plant kingdom and the animal kingdom.
Parasites are plants or animals that derive benefit from the metabolism of other plants or animals at the expense of the host and without providing some benefit to the host in return.
Immunity
Bacteria are single-celled organisms that can reproduce independently, while viruses are not cells and require a host cell to replicate. Bacteria are larger and can be treated with antibiotics, whereas viruses are much smaller and are typically treated with antiviral medications.
I wouldn't call bacteriophages parasites, but yes they are viruses which infect bacteria.
Pathogens. These are typically bacteria, viruses, fungi, or parasites that can cause disease by invading the body's tissues. Common examples include influenza viruses, E. coli bacteria, and malaria parasites.
Viruses differ from bacteria, fungi, and parasites in that they cannot reproduce independently; they require a host cell to replicate. While bacteria and fungi can divide and reproduce on their own through processes like binary fission or budding, viruses hijack the host's cellular machinery to produce new viral particles. Additionally, parasites are typically multicellular organisms that can reproduce sexually or asexually within or outside a host, whereas viruses are acellular and rely entirely on their host's biological processes for replication.
Viruses
Viruses are replication parasites that can do nothing until they take over a living cell. Bacteria are living cells.

Immunity
Skin diseases can be caused by viruses, fungi, bacteria, or parasites.
bacteria. viruses. fungi. protozoa .(protists). parasites.
Tapeworms, fleas, leeches, and most viruses, and some bacteria all fall under the label of parasites. Parasites benefit from another organism at that organism's expense.
Bacteria are single-celled organisms that can reproduce independently, while viruses are not cells and require a host cell to replicate. Bacteria are larger and can be treated with antibiotics, whereas viruses are much smaller and are typically treated with antiviral medications.
