DOI: 10.1128/aac.00497-25
Abstract: ABSTRACT Unpigmented, yeast-like Prototheca algae are emerging pathogens responsible for unusual infections in humans and animals. Their treatment is often unsuccessful, as traditional antifungals and antibacterials show unsatisfactory activity against Prototheca. Therefore, the development of… read more here.

Abstract: Achlorophyllous unicellular microalgae of the genus Prototheca (Trebouxiophyceae, Chlorophyta) are the only known plants that cause infections in both humans and animals, collectively referred to as protothecosis. Human protothecosis, most commonly manifested as cutaneous, articular,… read more here.
