Bacteria is a single celled microscopic organism. Bacteria can cause many different illnesses in humans. Bacteria are generally found in groups, not singularly.
Any type of living creature that can only be seen in a microscope is microscopic.
Bacterias can cause disease, so can virus. Even some types of proteins can cause severe disesases (Mad Cow Disease)
If you think of organism as in parasite, then look at malaria or Heartworm, or even Trikinosis, of which is a parasite sometimes found in pigs and other animals that some times eat dead animals.

An ameoba is a unicellular (one-celled) organism. It is commonly found in aquatic environments, and can cause disease.
Single celled lifeforms constitute most of the life on Earth. They are the majority of the producers in Earth's ecological system. They are major contributors to the processes that replenish our atmosphere, and form the basis of the marine food chain. On a smaller scale, single celled organisms perform equally important roles: they are a major part of the digestive system of most advanced animals. In humans, they are present in our intestines to aid in the breakdown of foodstuffs. Without them, we would not survive. Without single celled organisms, no life would be possible on Earth.
An Amoeba is a single cell organism
that's a virus.
An organism will replicate (cell divide) when it encounters a favorable environment that is rich or plentiful in the requirements that it needs to multiply. Most organisms do not replicate (exponentially) unless there is a nutrient in the environment that it needs. If there is low concentrations of the required nutrient then it will only divide in order to stay alive and continue its life cycle. For example: Most bacteria that cause disease in humans are opportunistic bacteria. Meaning that they live and are found on humans but they do not cause disease until they are given the chance to. At that point, they will multiply (cell divide exponentially) and cause disease. .
a bacterium
All the bacteria are the single celled organisms which do not have nuclear membrane and nucleus like eukaryotes.

Protozoans
They are a group of single-celled organisms, some of which cause disease. Malaria and dysentery are caused by protozoa.
A pathogen is an organism that can cause a disease.
There are many organisms that cause disease. Bacteria, like H. Pylori that causes stomach ulcers. Of course, rats can cause diseases and they are still organisms, just not single celled. They carry ticks, and their feces isn't good to breath in. Ticks carry diseases, and rats can carry sickness which can spread to humans.
Rust on your fence or rust on your crops? Rust usually, that occurs on metallic objects is iron oxide, it's an inorganic compound so no cells. Unicellular usually refers to organic organisms of single cellular structure. Another 'Rust' is an organism. Do you mean Rust fungus? It is a fungus and produces spores which spread and cause the crop damage, it's not unicellular. It has a complex structure.

Archaea are a group of single-celled microorganisms. There are no cases of confirmed diseases having been caused by archaea, yet this does not mean that they are not capable of causing disease.
