Discitis, or diskitis, is an infection in the intervertebral disc space that affects different age groups. Symptoms include severe back pain, leading to lack of mobility. In adults, it can lead to severe consequences, such as sepsis or epidural abscess, but it can also spontaneously resolve, especially in children under 8 years of age. Discitis occurs post-surgically in approximately 1–2 percent of patients after spinal surgery. There is debate as to the cause. Diagnosis is usually apparent on MRI, although plain X-rays and CT examinations can be suggestive. Treatment is difficult and usually

Protothecosis, otherwise known as Algaemia, is a disease found in dogs, cats, cattle, and humans caused by a type of green alga known as Prototheca that lacks chlorophyll and enters the human or animal bloodstream. It and its close relative Helicosporidium are unusual in that they are actually green algae that have become parasites. The two most common species are Prototheca wickerhamii and Prototheca zopfii. Both are known to cause disease in dogs, while most human cases are caused by P. wickerhami. Prototheca is found worldwide in sewage and soil. Infection is rare despite high exposure, and

One widely-known example of a sapronosis is Legionnaires' disease. Approximately a third of all known disease organisms are sapronoses. Almost all fungal infections are sapronoses, but there are no known sapronotic viruses.
