Many experts agree that the bacteria that causes these pink stains is most likely Serratia marcescens, a bacteria which is found naturally in soil, food, and in animals. Serratia, which produce a characteristic red pigment, thrive on moisture, dust, and phosphates and need almost nothing to survive.
More recently, Serratia marcescens has been found to be pathogenic to a small percentage of people, having been identified as a cause of urinary tract infections, wound infections, and pneumonia in hospital environments. Once established, the organism usually cannot be eliminated entirely.
There's a common misconception that pink slime is caused by mold, but it's most frequently caused by an airborne bacterium. Serratia marcescens thrives in damp environments — i.e., your bathroom. Because the bacteria are in the air, a water filter isn't always the best choice.
It's usually not as hazardous to your health as black mold and other fungi, but there are some pink mold dangers, such as urinary tract infections, intestinal problems and in rare cases pneumonia. You'll definitely want to rid your bathroom of the pink mold and take steps to keep it from coming back.
What is The Pink Slime? Plain and simple, the pink or orange slime is bacteria growth, not too dissimilar to that which you may have seen developing in other humid areas around your home, such as a shower or bathroom. The most common type of bacteria is a form of non-contagious salmonella mould.
If you're seeing pink stains in your bathroom, the problem is not usually water quality. Pink stains in bathtubs, toilets, and showers are caused by a bacteria called Serratia marcescens, which is found naturally in the environment. This bacteria is airborne and finds a home on moist surfaces.
The good news is Serratia marcescens is mostly harmless. Touching it while you're showering or cleaning won't cause any problems (in rare cases it can cause infections through open wounds or the eye). But it's unsightly and you don't want it in your bathroom. Here's how to get rid of “pink mold” for good.
You can kill it with simple household cleaning products. The best product to use is bleach. Bleach can kill pink mold bacteria, and also tackle any stains it leaves behind. This solution will work on most common surfaces, like baths, faucets, and bathroom tiles.
Bleach. Bleach can be used for mold and Serratia marcescens. If you opt for this course of action, make sure you have good ventilation in the room, and never mix bleach with vinegar or ammonia as it can cause toxic fumes.
Lactose (Lac) positive (pink colonies): Lactose fermenting species will grow pink colonies. Lactose fermentation will produce acidic byproducts that lower the pH, and this turns the pH indicator to pink. Example of Lac positive species: Escherichia coli, Enterobacteria, Klebsiella.
Gram-negative bacteria have cell walls with thin layers of peptidoglycan (10% of the cell wall) and high lipid (fatty acid) content. This causes them to appear red to pink under a Gram stain.
If an infected hand touches the eye and natural immunity is unable to fend off Serratia colonization, the result might be conjunctivitis, keratitis or tear duct infections, for example. Once in the bloodstream, Serratia bacteria can cause endocarditis, bacteremia, meningitis, osteomyelitis and arthritis.
Serratia infections should be treated with an aminoglycoside plus an antipseudomonal beta-lactam, as the single use of a beta-lactam can select for resistant strains. Most strains are susceptible to amikacin, but reports indicate increasing resistance to gentamicin and tobramycin.
S. marcescens has been shown to cause a wide range of infectious diseases, including urinary, respiratory, and biliary tract infections, peritonitis, wound infections, and intravenous catheter-related infections, which can also lead to life-threatening bacteremia.
Pseudomonas aeruginosa was killed in 10 seconds by all concentrations of ethanol from 30% to 100% (v/v), and Serratia marcescens, E, coli and Salmonella typhosa were killed in 10 seconds by all concentrations of ethanol from 40% to 100%.
The “pink mold” you may find in your shower actually isn't mold, but a very common strain of airborne bacteria that's found throughout the world. The bacteria, Serratia marcescens, cause that pink or even red slime you might find in your shower, toilet bowl, or around other water fixtures.
Pink residue is generally not a problem with water quality. In fact, pink residue is likely a result of airborne bacteria which produce a pinkish or dark gray film on regularly moist surfaces. Such surfaces include toilet bowls, shower heads, sink drains, and tiles.
Serratia is an airborne bacteria and can not survive in your chlorinated water supply. These airborne bacteria can come from any number of naturally occurring sources and the condition can be aggravated if you remove chlorine using an activated carbon filter.
Pink shower mold usually appears as a slimy build-up, though it does not always appear to be specifically pink. The bacteria get their colour from a red pigment that is produced at room temperature. Depending on the growing conditions, the resulting color can range from salmon pink to orange or even blood red.
Pink mould refers to any mould species that appear pink throughout their maturity stages. This includes Serratia Marcescens, Aureobasidium Pullulans and Fusarium. Did you know Serratia Marcescens, the most common type of pink mould, is actually a bacteria, not a fungus?
Pink mold is common in bathrooms, kitchens and other high-moisture environments. However, despite the name, pink mold is a bacteria, not a fungus. Although there aren't as many potential risks as true molds, pink mold has been linked to wound infections, urinary tract infections and even pneumonia.
Symptoms of a rash from mold
itchiness. dry and scaly skin. raw and sensitive skin. brown or pink skin.
It produces a fishy-urinary odor (trimethylalamine). It can be isolated from food, soil, water, plants, insects, and sewage. It is a potential pathogen for insects, animals, and humans and is an important cause of nosocomial (hospital-acquired) infections in humans.
