The most common cause of bacterial nail infection, Pseudomonas aeruginosa, is now included in our onychodystrophy panel*
*Pseudomonas aeruginosa testing not currently available in the State of New York.
Green nail syndrome, characterized by a greenish black discoloration of the nail, is caused by the growth and colonization of P. aeruginosa. Predisposing conditions can include: onycholysis, onychomycosis, diabetes mellitus, as well as occupations where feet are frequently exposed to wet conditions.
The Importance of Including the Detection of Green Nail Syndrome (GNS) with PCR in Onychodystophy Testing
Fungal infection stimulates bacterial colonization within the nail and overgrowth of P. aeruginosa in culture inhibits the isolation of fungus1
Screening for fungal coinfections and, if needed antifungal treatment, in patients with GNS is critical1
Molecular testing is needed to detect GNS because of a strong relation between fungal and P. aeruginosa nail infection.2
Coinfection with “Trichophytan rubrum and Pseudomonas, (are) a common occurrence.”3
