Protothecosis (pronunciation: pro-toe-the-co-sis) is a rare infection caused by the algae of the genus Prototheca.

Etymology

The term "Protothecosis" is derived from the Greek words "protos" meaning first and "theca" meaning case or sheath. It was first described in the medical literature in the early 20th century.

Definition

Protothecosis is a rare infection caused by the algae of the genus Prototheca. These organisms are ubiquitous in nature and can be found in soil, sewage, and in the intestinal tracts of healthy animals and humans. However, they can cause disease in both humans and animals, particularly in individuals with compromised immune systems.

Symptoms

The symptoms of protothecosis can vary depending on the site of infection. Cutaneous protothecosis, the most common form of the disease, typically presents as skin lesions that may be accompanied by pain or itching. Systemic protothecosis, which is less common, can affect multiple organs and may cause symptoms such as fever, weight loss, and fatigue.

Diagnosis

Diagnosis of protothecosis is typically made through the identification of Prototheca organisms in tissue samples or body fluids. This can be achieved through various laboratory techniques, including microscopy, culture, and molecular methods such as polymerase chain reaction (PCR).

Treatment

Treatment of protothecosis typically involves the use of antifungal medications, as Prototheca organisms are susceptible to many of the same drugs used to treat fungal infections. However, the optimal treatment regimen is not well established due to the rarity of the disease.
