RESUMO
In 2014, ISHAM formed a new working group: "Medical Phycology: Protothecosis and Chlorellosis." The purpose of this working group is to help facilitate collaboration and communication among people interested in the pathogenic algae, to share ideas and work together. Here we present reports on recent work we have done in five areas. 1. The history of medical phycology as a branch of science. 2. Aspects of the genetics of Prototheca. 3. Aspects of the proteins of Prototheca. 4. Human infections caused by Prototheca. 5. Dairy cow mastitis caused by Prototheca.

We present a Prototheca wickerhamii wound infection case that failed treatment with ketoconazole but was cured with amphotericin-B plus tetracycline. The patient was immunocompetent but had had local steroid injections. We reviewed another 159 cases from the literature. Prototheca has infected many areas of the human body, but most often skin, olecranon bursa, or wounds. Prior treatment with steroids and immune deficiencies are contributing factors. Itraconazole and fluconazole are reasonable initial treatments for patients with mild infections. For serious infections, or for infections that have failed azole treatment, amphotericin-B is the treatment of choice.
