This publication is available in a PDF file format only.

Prototheca spp. are mastitis-causing pathogens that are classified as colorless algae. Prototheca spp. will appear on blood agar as creamy-white or grayish-white pasty colonies after 24 to 36 hours of incubation. Colonies could be confused with coagulase-negative staphylococci or yeast but can be differentiated when Gram staining because Prototheca spp. will exhibit spherical or oval sporangia with or without endospores.
