Answers
Answer:
Bacteria
Bacteria can live in animals and in the environment.
Not all bacteria cause disease.
People and animals have bacteria living on and in them that do not cause disease.
Examples of diseases in animals caused by bacteria are anthrax, blackquarter and tuberculosis.
Bacteria can infect wounds, and that is why wounds should be treated.
Fungi
Fungi occur widespread in the environment (soil, air and water) and include mould on stale food and mushrooms.
Fungi need to grow on organic material in order to feed, and this can include animals and people.
An example of a fungal disease in animals is ringworm.
Some fungi are normally harmless, but can cause disease in some situations, especially after prolonged use of antibiotics.
Some fungi can also produce toxins or poisons which can be a problem when food becomes stale or wet.
Protozoa
Some protozoa can live outside cells, especially the type that causes trichomonosis, a venereal disease in cattle. Others need to live inside cells, and include those causing coccidiosis, redwater, heartwater and gallsickness.
Animals can be poisoned by chemicals (such as insecticides and dips), poisonous plants and fungal toxins.
They can also be poisoned when bitten by snakes, scorpions and spiders.
