Prototheca

 [pro″to-the´kah]
a genus of ubiquitous yeastlike organisms generally considered as being achloric algae, occurring as spherical to elliptical cells containing thick-walled autospores. P. wickerha´mii and P. zop´fii are the species involved in human and animal infection. See also protothecosis.

Prototheca

(prō'tō-thē'kă),
A genus of an achlorophyllous alga; two species, Prototheca zopfii and Prototheca wickerhamii, cause protothecosis.

Prototheca

a genus of achloric algae, possibly a mutant form of Chlorella. They are saprophytic organisms that usually occupy freeliving niches in a great variety of places. Very rarely infection may occur in canine and feline skin, bovine mammary gland, canine eye and the canine colon. Identified species are P. stagnora, P.trispora, P. wickerhami, P. zopfi.
