considered a plant lacks chlorophyll www.omafra.gov.on.ca/english/livestock/dairy/facts/danger.htmUnlike green algae, Prototheca lacks the pigment chlorophyll. The colourless organisms are commonly found in manure, sewage, soil and water. They grow rapidly when humidity is high and organic material is plentiful. The organism is common throughout the environments of some farms, particularly where there's damp manure. aqt

www.pubmedcentral.nih.gov/articlerender.fcgi?artid=309174Protothecosis is a disease found in dogs, cats, cattle, and humans caused by a type of green algae known as Prototheca that lacks chlorophyll. It is the only known infectious pathogen that is also a plant.[1] The two most common species are Prototheca wickerhami and Prototheca zopfii. Both are known to cause disease in dogs, while most human cases are caused by P. wickerhami.[2] Prototheca is found worldwide in sewage and soil. Infection is rare despite high exposure, and can be related to a defective immune system.[3] In dogs, females and Collies are most commonly affected.[4] The first human case was identified in 1964 in Sierra Leone
