Immunity
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.
I wouldn't call bacteriophages parasites, but yes they are viruses which infect bacteria.
Lysosomes. ;)
There are really 5 main groups; viruses, bacteria, fungi, protozoa (which includes the malaria parasite) and Helminthes (which includes parasites such as flatworms and roundworms). Moulds are classified as fungi.
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.

Skin diseases can be caused by viruses, fungi, bacteria, or parasites.
Viruses are replication parasites that can do nothing until they take over a living cell. Bacteria are living cells.
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.
Prions, Viruses, Bacteria, Fungi, and Animal Parasites.
Diseases caused by bacteria, viruses, yeasts or parasites can affect organs.
Bacteria, viruses, fungi, protozoa (aka protists), parasites.
"germs" -- bacteria, viruses, parasites, fungi, and possibly prions
