Pseudomonas Nail Infection

Pseudomonas Nail Infection

Pseudomonas Nail Infection: Pseudomonas nails usually appear as green or dark green spots underneath the fingernails & toenails.



What Is a Pseudomonas Nail Infection:

Pseudomonas nail infection can take place between the nail plate & the nail bed. It results in a green looking toenail or fingernail.

Pseudomonas Nail Infection
The pseudomonas infection can cause a distinct green spot toward the distal end of your nail plate.
  • Pseudomonas is not a mold as it is reputed to be in the nail tech industry, but a bacteria!
  • It is frequently referred to as “greenies” or “green nails” by the nail tech industry.
  • The greenish black color is caused by a bacteria that loves oxygen and water called Pseudomonas aeruginosa.
  • It is frequently acquired by getting dirt under your nails from pond water, hot tubs, and pools.
  • Nail irritation combined with increased moisture leads to it colonizing your fingertips.




How Does Pseudomonas Nail Infection Occur:

Two things need to occur before a Pseudomonas nail infection occurs.


1)There must be microscopic cracks or injury underneath your fingernail or toenails.
Pseudomonas Nail Infection
Trauma or microscopic cracks must first occur below the fingernail or toenail before the pseudomonas can get underneath the nail.
  • This usually occurs due to scrapping with your nails or damaging them microscopically.
  • There could be nail plate separation from the nail bed (onycholysis).
  • There could be a paronychia (inflammation of the nail border).
  • This allows a entry point for the bacteria.
  • Without this entry point, the bacteria could never get underneath the nail plate.


2)The Pseudomonas bacteria then gets underneath the nail & replicates.

A pseudomonas nail infection can then manifest itself after it gets through the cracks.
  • Once these cracks occur, the Pseudomonas bacteria can burrow itself underneath the toenail or fingernail.
  • The bacteria is then safe underneath the toenail and can grow.
  • Antibiotics or topical treatment may be needed to resolve this condition.

If there is damage to your nails, this gives the bacteria the perfect way in!



Who is at risk for Pseudomonas infection?
  • The risk of Pseudomonas goes up with dirt.
  • Those who have cracks underneath the fingernails & toenails.
  • There could be nail plate separation from the nail bed (onycholysis).
  • There could be a paronychia (inflammation of the nail border).
  • Using artificial nails, nail polish or nail polish remover.


Pseudomonas Nail Infection
Pseudomonas is an gram negative aerobic bacteria that can cause green fingernails & toenails.



Artificial Nails Increase The Chances:
  • Artificial nails, toenail polish & toenail polish remover increase stress on your nail plate.
  • This can give the bacteria an advantage in getting underneath the nail and growing.
  • Consider going natural until the bacteria is resolved!


Pseudomonas Nail Infection Treatment:

If you ever have any worry, make sure to see your podiatrist for antibiotics.

  • These include both oral & topical!

Why Does It Work?

  • A Michigan State University (MSU) study shows that Vinegar has anti-microbial properties.
  • This study focused on fungal toenails, but pseudomonas is much more superficial and easier to treat than toenail fungus.
  • Apple Cider Vinegar provides a inhospitable acidic environment for the fungus & the bacteria.
  • It is a fungicidal chemical, this means that it kills the bacteria rather than just preventing its growth.
  • It is very common to hear people say they feel immediately better after using this just for a short time!

  • It usually manifests as thick yellow toenails, but there can be brown and blackmarks as well.
