Prototheca spp. cause numerous infections in a wide variety of species, including treatment‐unresponsive mastitis. Thus, the search for an effective therapy is essential. Silver nanoparticles are compounds with high therapeutic potential. This study aimed to evaluate the susceptibility profile and morphological changes in Prototheca spp. treated with biogenic silver nanoparticles (Bio‐AgNP). The algaecide activity was evaluated in microplates by microdilution method, resulting in a MIC50 of 30 μg ml−1 and a MIC90 of 60 μg ml−1. Scanning electron microscopy demonstrated changes in the surface of Prototheca bovis cells following treatment. The algaecide activity of Bio‐AgNP suggests a therapeutic potential as a novel approach for the control of Prototheca spp. in bovine mastitis.
