Pseudomonas Toenail Infection Green nails = infection with a bacteria called “Pseudomonas”. Not all bacterial infections are green, only the ones caused by Pseudomonas. (Dr. Harvey Lui and University of British Columbia) What: When nails appear green in colour, this could be due to a bacteria called pseudomonas. The bacteria, which creates a green pigment, typically affects people who often submerge their nails in water, such as a dishwasher. What to do: See a doctor who can treat the condition with diluted bleach. #Pseudomonas #Toenail #Infection #Clinical #Photo #Podiatry #Dermatology
