Green nails, also known as greenies or Green nail syndrome, are caused by an infection from the bacteria pseudomonas aeruginosa, which is found in water sources, humans, animals, and soil. The bacteria thrive in damp, warm, and nearly oxygen-free environments, which is why it is commonly found around swimming pools, hot tubs, bathtubs, and showers. The infection causes a green discoloration on the nails, which can spread and turn dark green or black as it progresses. While it does not cause any health problems, severe cases may require medical treatment such as antibiotics or antifungal cream.

What You'll Learn
Green nail syndrome (GNS) is caused by bacteria
Green nail syndrome (GNS) is a rare condition that occurs when the nail turns green due to exposure to bacterial organisms, most commonly Pseudomonas aeruginosa. This bacteria is frequently found in nature, including in water sources, humans, animals, and soil. While it does not typically survive on dry, healthy skin, it can thrive in moist environments.
The nail acts as a physical barrier to prevent bacterial infections. However, in certain conditions, this barrier can be impaired, allowing bacteria to colonize and cause an opportunistic infection. For example, hyper-hydration or damage to the epidermis, the layer of skin beneath the nail, can create an opening for bacteria to enter. Individuals with weakened epidermis barriers, such as those who frequently immerse their hands in water or have pre-existing nail problems, are at a higher risk of developing GNS. Additionally, artificial nails and manicures have been linked to diagnostic delays in GNS cases.
The green discoloration observed in GNS is caused by pigments secreted by the bacteria, such as pyocyanin and pyoverdin. As the infection progresses, the stain can spread on top of or under the nail, turning dark green or even black. It is important to note that the presence of green discoloration does not always indicate an infection, as it could be due to staining from certain manicure products or environmental exposure.
To prevent GNS, individuals should avoid prolonged exposure of the nails to water and take precautions to maintain a healthy epidermis seal. This can include wearing waterproof gloves or rubber boots when working with water or chemicals and practicing good nail hygiene. Keeping the nails trimmed and dry can also help prevent bacterial colonization. In some cases, more invasive treatments, such as surgical removal of the infected nail, may be necessary. However, most bacterial nail infections can be effectively treated with topical or oral antibiotics.

GNS is linked to frequent hand-washing
Green nail syndrome (GNS) is a bacterial infection that causes the nail to turn green. It is most commonly caused by the bacteria Pseudomonas aeruginosa, which is frequently found in nature, including in water sources, humans, animals, and soil. These bacteria thrive in moist environments and can colonize the nail when the epidermis barrier is impaired, such as through frequent hand-washing.
Frequent hand-washing can increase the risk of developing GNS by creating a moist environment conducive to bacterial growth. The seal between the nail and finger acts as a physical barrier to prevent infection. However, frequent hand-washing can lead to hyper-hydration or damage to the epidermis, impairing this barrier and allowing bacteria to colonize the nail. This is particularly common in individuals whose hands are frequently immersed in water, such as bartenders, dishwashers, and those who work with chemicals or detergents.
Additionally, frequent hand-washing can cause dryness and cracking of the skin, creating additional entry points for bacteria. While good hand hygiene is essential for preventing the spread of pathogens, excessive hand-washing can disrupt the skin's natural moisture balance and increase susceptibility to GNS. It is important to maintain a balance by washing hands with gentle soaps that are not irritating to the skin and using lotion to prevent dryness and cracking.
To prevent GNS, individuals who frequently wash their hands should take extra precautions. This includes ensuring that hands are thoroughly dried after washing, especially in the areas around the nails. Wearing waterproof gloves during activities that involve prolonged exposure to water or chemicals can also help to create a physical barrier against bacteria and prevent excessive moisture.
Overall, while frequent hand-washing can increase the risk of GNS by creating a favorable environment for bacterial growth and disrupting the skin's natural barrier, proper hand hygiene and moisture management can help mitigate this risk. Maintaining short, trimmed nails can also reduce the surface area for bacterial colonization and facilitate drying after hand-washing.

GNS is characterised by discolouration and odour
Green nail syndrome (GNS), also known as chloronychia or Goldman-Fox syndrome, is characterised by discolouration of the infected nail, inflammation of the skin around the nail (paronychia), and an odour resembling fruit. The discolouration can range from light or bluish-green to dark green or black, and may also appear as transverse green stripes. GNS is caused by exposure to a bacterial organism, most commonly Pseudomonas aeruginosa, which thrives in moist, warm, and nearly oxygen-free environments.
The bacteria secrete pigments such as pyocyanin and pyoverdin, which cause the green discolouration. GNS occurs rarely in healthy individuals but can affect those who are immunocompromised, frequently immerse their hands in water, or have pre-existing nail problems. The elderly and individuals who have experienced trauma to a finger or nail are also at higher risk.
Diagnosis of GNS is typically made through a physical examination of the nail, although nail scrapings and cultures may be necessary to rule out other infections. Treatment options for GNS include topical or oral antibiotics, antiseptics, and, in severe cases, surgical removal of the infected nail. Keeping the nails dry and avoiding excessive water exposure are crucial in preventing and managing GNS.
In terms of home remedies, individuals can try soaking their nails in citric acid (lemon juice), using a nail whitening pen containing hydrogen peroxide, or applying vitamin E oil or baking soda crystals mixed with warm water. It is important to note that these remedies may take a few weeks to show results, and patience is key during the restoration process.

Treatment options include topical antibiotics
A green nail is often an indication of an infection, known as Green Nail Syndrome or "greenies", caused by the common bacteria pseudomonas aeruginosa. This bacteria is frequently found in nature, including in water sources, humans, animals, and soil. The bacteria secrete pigments such as pyocyanin and pyoverdin, which cause the green discolouration.
Green Nail Syndrome is characterised by the discolouration of the infected nail, inflammation of the skin around the nail, known as paronychia, and an odour resembling fruit. The infection can occur in two places: between the nail plate and the nail bed, or between the acrylics and the nail plate.
If you notice green discolouration on your nails, there are several treatment options available. Firstly, it is important to keep your nails dry and avoid excessive immersion in water, as the pseudomonas bacteria thrive in warm, damp, and nearly oxygen-free environments. Trimming your nails and keeping them short can help to prevent the spread of the infection. Filing or buffing off the discoloured area can also help, but be sure to throw away the nail file afterwards to avoid cross-contamination. Disinfecting your nails with rubbing alcohol, apple cider vinegar, white vinegar, or a diluted chlorine bleach solution can help to kill the bacteria.
In terms of topical antibiotics, there are several options that have been used successfully to treat Green Nail Syndrome. These include:
- Tobramycin eye drops: These have been shown to be an easy and safe treatment option, and are particularly effective for individuals who are reluctant to take oral medications.
- Nadifloxacin: This is a topical acne medication that has been used off-label to successfully treat Green Nail Syndrome. It is applied once daily to the nail plate for 6 weeks.
- Silver sulfadiazine, gentamicin, ciprofloxacin, bacitracin, and polymyxin B: These topical antibiotics are typically prescribed for moderate cases of Green Nail Syndrome.
In some severe cases, oral antibiotics or antifungals may be necessary. However, it is important to note that P. aeruginosa is naturally resistant to a wide range of antibiotics, so antibiotic treatment should be initiated after a laboratory test for antibiotic sensitivity.

Preventative measures include wearing waterproof gloves or rubber boots
A green-tinted discolouration on your nails can be caused by a bacterial infection known as "greenies" or chloronychia. This is caused by the common bacteria pseudomonas aeruginosa, which thrives in warm, damp, and nearly oxygen-free environments.
If your job requires you to work with chemicals or detergents, or if your hands are frequently wet, you should consider wearing waterproof gloves. This will help to protect your hands and prevent infection. Look for gloves that do not irritate the skin and are made from breathable materials. It is important to let your hands dry out as much as possible between wearing gloves, and to keep your nails short and clean.
Waterproof gloves are especially important if your work involves mixing chemicals, as inadequate protection can result in a constantly moist environment, leading to green nails. Similarly, if your work involves "wet" activities such as gardening or dishwashing, wearing waterproof gloves can help to prevent the pseudomonas bacteria from becoming trapped in your nails.
In addition to gloves, wearing rubber boots can help to keep your feet and toes dry, reducing the risk of nail infections. This is particularly important for individuals who work in wet environments or participate in activities that involve prolonged periods of time in tight-fitting shoes, such as soccer players and military personnel.
