Klebsiella infections are more common than you would think. Because you have ended up here I am assuming that you or someone you know has found a Klebsiella infection and you want to know more.

Read on to learn what Klebsiella actually is, the symptoms it may be causing and possible treatment options.

A Primer On Klebsiella Bacterial Overgrowth

Members of the Klebsiella genus are common residents of the human gastrointestinal tract.

At times, and in manageable numbers, they are considered commensal organisms but frequently, in the case of Klebsiella pneumoniae, they can act as opportunistic pathogens (1).

Commensal – living with, on, or in another, without injury to either

Basically the subtext here is that they can be normal residents of a healthy gut, but, when given the chance, can overgrow and cause issues.

Belonging to the Enterobacteriaceae family, Klebsiella pneumoniae is a species of gram-negative bacteria.

It has the ability to take on a pathogenic role in the digestive tract when there is an imbalance or a weakened immune system. Often this takes the form of a hospital acquired infection known as a nosocomial infection (2).

Why Is Klebsiella Hard To Treat?

It’s a good question. Let’s get into it.

The paper Molecular pathogenesis of Klebsiella pneumoniae outlines the difficulty in treating Klebsiella infections.

Klebsiella has the innate ability to form biofilms both in the human body and on medical devices. By forming biofilms Klebsiella protects itself from the immune response as well as from antimicrobial treatments (herbal and pharmaceutical). 

The capsule polysaccharide, or CPS, found on Klebsiella pneumoniae also contributes to many of it’s immune resistant capabilities.

Klebsiella can inhibit phagocytosis (being eaten by white blood cells) by inhibiting different white blood cells (macrophages and neutrophils) ability to bind to the bacteria.

Not surprisingly more virulent strains of Klebsiella show greater capabilities at blocking the function of different white blood cells. Another immune dodging mechanism displayed by certain virulent strains of Klebsiella pneumoniae is the ability to dampen down the initial inflammatory response by the innate immune system.

Yet a third aspect of resistance is the found in the protective nature of the CPS. As second line defence the innate immune system releases different antimicrobial peptides as a response to infection. Not only does Klebsiella’s protective CPS layer act as a shield it is also released from the bacteria to block incoming antimicrobial peptides, tying them up and reducing contact with the bacterial cells.   

Yet another key issue which leads to difficulties in treatment is the fact that many strains of Klebsiella are becoming more and more resistant to frontline antibiotic treatments. 

So we can see some treatment issues arising here.

Let’s move onto some symptoms of Klebsiella infections and circle back to treatment ideas later in the article.

Symptoms Of Klebsiella Infections

I have had a Klebsiella infection so I know first hand some symptoms it can cause.

That said it can be hard to tease out what infection is causing what symptom.

My symptoms, confirmed by a comprehensive stool test included

  • Intense headaches
  • Loose stools
  • Sore lymph around the throat
  • Increases food intolerances – coffee/chocolate/dairy/sugar
  • Trouble sleeping
  • Anxiety

Again it is very hard to pin down the root cause based on symptoms. That’s why it is so important to test!

From the literature

“Klebsiella pneumoniae, a member of the Enterobacteriaceae family, is a common human bacterial pathogen that can cause urinary tract infections, pneumonias, bacteremia, pyogenic liver abscesses, skin abscesses and necrotizing fasciitis. It is recognized as a highly pathogenic organism that causes disease in the community and nosocomial settings.” (1).

Finding Klebsiella. Testing Options and Alternatives 

Generally it is quite easy to find Klebsiella infections by running a more comprehensive stool test known as a CDSA (complete digestive stool analysis.

Unfortunately these more specific and functional testing are rarely offered by GPs.

Most of the time you will have to pay out of pocket.

For Australians Nutripath offers a CDSA although your health practitioner (GP, herbalist, naturopath) will have to order it for you.

For me paying for the test (approx $250 all up) was a no-brainer.

After experiencing a range of very unpleasant symptoms from drinking unfiltered tank water in the Byron Bay hinterland I ran the comprehensive diagnostic stool analysis from Nutripath and found not one, not two, but five different infections. 

Dealing with Infections. How To Treat Klebsiella Infections

Antibiotics are the frontline treatment offered by allopathic biomedicine.

Many times antibiotic treatment was the original insult that disrupted the gut microbiome and allowed members from the Proteobacteria phylum (like Klebsiella) to overgrow.

It is a choice that everyone has to make for themselves.

Unless the infection was life-threatening I would consider taking herbal antimicrobials first every time. Following up the antimicrobial treatment with a well planned gut rebuilding protocol is essential.

One particular herbal medicine with science to back it up is pomegranate husk tincture. klebsiella infection treatment natural byron bay australia gut health herbalist naturoath

This is a particularly effective treatment, especially when combined with other supporting and complimenting herbal medicines.

Herbs that can improve the effects of pomegranate husk tincture include the following

  • Clove tincture – can help with the biofilms that Klebsiella forms
  • Oregano leaf
  • Propolis
  • Baical Skullcap
  • Garlic

There are a range of other antibacterial herbs. A few that really stand out include the high berberine herbs like Coptis chinensis, barberry and even goldenseal. Unfortunately these herbs don’t combine well with pomegranate husk due to their active components (alkaloids and tannins don’t play well together).

Also many of these herbs can and will negatively impact the gut flora so we need to focus on supporting it while simultaneously treating the Klebsiella infection.

This is a great point on why working with a herbalist trained in the complexities of gut infections is so important.

Dietary Considerations For Klebsiella Infections

A previous article outlined the use of prebiotic fibres and starches to help boost the gut microbiota.

In the case of Klebsiella infections reducing simple starches and certain colonic foods could be a wise strategy as this particular bacteria favours starch as food.

One study suggested reducing complex carbohydrates in response to Klebsiella infection (4). The use of certain prebiotics may still be of value as they selectively feed beneficial microbes, aiding in the treatment of dysbiosis. 

Targeted prebiotics and probiotics can helping to support the gut flora and improve antimicrobial effects of the herbs.

Apart from that I think anything that helps with your symptoms should be investigated. For me it was a reduction in refined carbohydrates.

The next article will cover the possible connections between Klebsiella infections and Ankylosing Spondylitis.

  1. I went to an integrative Dr had the same stool test as you & have+++ klebsiella. I am freaking out. I don’t know whether to continue insulin or if I can ever get rid of it. She is going to give me herbal stuff but they only say they are 60% effective. I’m really scared after reading how resistant they can be!

    1. Yes this is the big debate. Do prebiotics contribute to dysbiosis and feed pathogenic bacteria? Some say yes and cite in-vitro (test tube) studies and others say no and cite human trials.

      Inulin may not be the best prebiotic but others have been shown to decrease klebsiella or the klebsiella family, Enterobacteriaceae including partially hydrolysed guar gum and a galacto-oligosaccharide/ fructo-oligosaccharide mix.

      It could very much be to do with the acidifying of the colon and the drop in pH from the beneficial fermenters (bifido’s and lacto’s) producing all that incredible butyrate. More here: http://www.byronherbalist.com.au/prebiotic-update-details-building-gut/

  2. Hi .. thanks. I am happy to have a paid appt on face time. I need to reduce starch which I haven’t Been indulging in since Christmas .. but was taking 3 teaspoons of Zinulin a night… the worst thing for klebsiella!
    I am going os on August 16 & really want to get the levels down. I don’t know how to avoid starch/ complex carbs to starve klepsiella & yet build or keep up my other good gut bacteria … which I’ve tried to be vigilant about .. could you email me as to arrange an appt please. Thanks Prue. My Ph is 0419 876 608

    1. Unfortunately I’m still working on my health science degree so I can’t give any specific advice or take on patients. Best I can do at the moment is publish findings from my research and hopefully point you in the right direction. Sorry I can’t be of more help!

  3. Great read!
    I have always been healthy, fit & slim, never had a problem
    With my health until 9 months ago when below symptoms began arising.
    -Mind fog
    -food intolerances (dairy)
    – anxiety
    – weak/fatigued
    -weight gain and extreme struggle to lose!
    -severe bloating

    Tests after tests with no answers.
    Eventually got told to do a CDSA stool test, resulting only bad bacteria highlighted,
    Klebsiella ++++

    I have been taking natural herbs, oregano oil tablets, & been eating extremely clean, sticking to a 1300 calorie diet. No processed foods or high starch. Been doing this for over a month now and don’t seem to feel any different.
    Is there a reason I may not be able to shake this bacteria? Should I be only drinking filtered or bottled water?

    So frustrating when you’re trying everything you can! ?

    1. Citricidal and silver biotics work very well against klebsiella and many other bacterias and yeasts.
      Also biofilm booster like interfase plus, 4-8 caps before bed.
      No sugar and low carb diet for about a month is highly recommended.
      Good quality probiotics after that is a must. Not those 50 billions lactobacillus/bifidobacterium crap. I’m talking about s boulardii and bacillus species.

      1. It sounds like you’ve had some experience in treating bacterial overgrowths Leon.

        Just a note. I would avoid any grapefruit seed extract products (it’s a contaminated product – see link below – and has a very negative impact on the gut microbiome).

        Great points on the biofilm agents and the probiotic recommendations are on point.

        Thanks for the comment!
