Protothecosis is an infection caused by members of the genus Prototheca (achlorophyllous algae found ubiquitously in the environment). Prototheca organisms are opportunistic and infect humans, some domestic animals, and wildlife.

Protheca is a genus of beetles in the family Ptinidae. There are at least three described species in Protheca. [1] [2] [3] [4] Protheca hispida

From the Greek proto - (first) + thēkē (sheath), Prototheca is a genus of variably shaped spherical cells of achloric algae in the family Chlorellaceae. Wilhelm Krüger, a German expert in plant physiology and sugar production, reported Prototheca microorganisms in 1894, shortly after spending 7 years in Java studying sugarcane.

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. [1] .

Prototheca is a microalgae known to cause infections in humans, with protothecosis most commonly presenting as olecranon bursitis or localized soft tissue infection. Disseminated disease can be seen in immunocompromised patients.

Mar 19, 2015 · An online resource devoted to North American insects, spiders and their kin, offering identification, images, and information.

Human protothecosis is a rare infection caused by members of the genus Prototheca. Prototheca species are generally considered to be achlorophyllic algae and are ubiquitous in nature. The occurrence of protothecosis can be local or disseminated and acute or chronic, with the latter being more common.

Jul 19, 2024 · Protothecosis is an emerging infectious disease that has garnered increasing attention from the medical and veterinary communities. Caused by algae of the genus Prototheca, this rare but significant infection affects both humans and animals.

Prototheca spp. are unicellular, achlorophyllous microalgae that occur in a wide range of natural habitats, occupying mostly aqueous environments with high organic matter content. Prototheca spp. are opportunistic pathogens of both humans and animals, where the precise pathogenic mechanisms of protothecal infections are still mainly unclear.
