How prevalent is Bartonella in people who have Lyme disease? (2022)

At a meeting of the federal Tick-Borne Disease Working Group on March 1, Ben Beard, PhD of the CDC made a highly significant statement that passed without remark at the time.

Beard’s statement was in reply to a comment by Monica Embers, PhD, also a member of the working group. Embers noted that several slides from Beard’s Clinical Presentation and Pathogenesis subcommittee mentioned neuropsychiatric illness and neuropathic manifestations of Lyme disease.

“We’re seeing a lot more neuropsychiatric disease associated with Bartonella,” said Embers. “I’m wanting to hear more about your thought process and your recommendation with respect to bartonellosis?”

Bartonella’s “significant impact”

Beard replied: “In my view Bartonella is ubiquitous. There are multiple different Bartonella species. A lot of people are exposed to cats and fleas, and Bartonella henselae–or cat scratch disease–is pretty common. Our group looked at it as an illness that is associated with people with other tick-borne illnesses. Not necessarily agreeing that it’s tick-borne—for me the jury is still out for that—but I’m perfectly convinced that it is very common, and that it may be confounding the diagnosis, and that it is an important co-infection. We need not get side-tracked on whether or not it’s tick-borne. We need to agree that it’s a common infection, commonly seen in patients with other illnesses, and it can have a significant impact on clinical outcome and presentation.”

This is actually a showstopper of a comment.

The CDC has long declined to categorize bartonellosis as tick-borne and has not considered it a co-infection of Lyme.

Even today, the CDC website states: “Ticks may carry some species of Bartonella bacteria, but there is currently no causal evidence that ticks can transmit Bartonella infection to people through their bites.”

Yet, as Beard observed, Bartonella is very common in people with Lyme disease.

What the data says

In MyLymeData, LymeDisease.org’s patient-led research project, 60% of patients with chronic symptoms of Lyme disease report co-infections. A previously published LymeDisease.org survey of over 3,000 patients found that over 50% had co-infections, with 30% of patients reporting two or more. Bartonella (28%) was the second most commonly reported co-infection associated with chronic Lyme disease. (Johnson, L., et al., 2014)

Bartonella does not respond to standard treatment for Lyme disease, and it is notoriously difficult to detect through standard tests. Moreover, Bartonella is not included in standard surveillance testing for ticks, and cases of the disease are not tracked by the CDC

Which leads me to the elephant in the room: nobody knows how many cases of bartonellosis there are in the US—or anywhere else for that matter.

What is bartonellosis?

Bartonellosis is caused by one of many species of the bacterium Bartonella. It is harbored in wild and domestic animals, and can be transmitted to humans through a number of different pathways including fleas, flies, lice, animal bites, animal scratches, ticks, bedbugs, and possibly through maternal fetal transmission. (Maggi RG, et al., 2015; Reis C, et al., 2011)

First identified in 1990, Bartonella henselae bacteria is the most common cause of bartonellosis in humans. Bartonella henselae infection, also called cat scratch disease, is frequently caused by flea bites or the scratch of an infected cat. The primary reservoirs for B. henselae across the world are domestic and stray cats, and the primary vector is the cat flea (ctenophalides felis). (Breitschwerdt, E.B., 2017)

Prior to 1990, there were only two diseases known to be caused by Bartonella bacteria. One was “Carrion’s disease,” endemic to parts of South America, caused by Bartonella bacilliformis.The other was“trench fever,” which infected many soldiers during World War I, caused by Bartonella quintana. Though the illness was first described in 1915, Bartonella quintana was not molecularly identified as its cause until 1961. (Breitschwerdt, E.B., 2017)

We now know that these bacteria have been infecting humans for thousands of years. Researchers discovered Bartonella quintana in a 4,000-year-old human tooth in France. (Drancourt M., et al., 2005)

Today, at least 40 different species of Bartonella have been identified.About half of them are known to cause symptoms in humans or animals.

Bartonella is a stealth pathogen

At a recent conference, Dr. Ed Breitschwerdt, DVM, a leading expert in the field, explained how Bartonella can invade and “literally affect every system in the body.” This includes the: cutaneous, muscular, skeletal, endocrine, cardiovascular and nervous systems.

He reviewed several recent studies implicating Bartonella infection in the brain in relation to several neuropsychiatric and autoimmune manifestations.

According to Breitschwerdt, these bacteria are extremely difficult to find in humans because they are slow growing and can hide within cells.

He explained how Bartonella, which are intracellular bacteria, have the ability to:

  • invade red blood cells, wall themselves off, and hide from the immune system (immune evasion)
  • migrate into the nervous system via macrophages (Trojan horse)
  • penetrate the blood brain barrier via endothelial cells and pericytes
  • persist within the brain via microglial cells.

Considering the number of different species and different methods of contracting Bartonella, Dr. Breitschwerdt ponders, “Is Bartonellosis a modern-day hidden epidemic?” (Breitschwerdt E.B., 2014)

Symptoms of bartonellosis

The symptoms of bartonellosis can range from mild to life-threatening, depending on the Bartonella species and the health of those infected. Furthermore, a growing body of evidence links Bartonella to neuropsychological symptoms.

The most commonly reported neurological symptoms include sleep disorders, mental confusion, memory loss, brain fog, irritability, rage, anxiety, panic attacks, depression, migraines, tremors, hallucinations, psychosis and postural orthostatic tachycardia (POTS).

Additional symptoms common to bartonellosis are swollen lymph nodes (especially around the head, neck and arm pits), bone pain (especially shins), pain in the soles of the feet, low grade fever in the morning, night sweats, tender nodules along the extremities, gastrointestinal pain, and skin markings (striae) that resemble stretch marks.

The table below lists the known species of Bartonella associated with human disease, the most common symptoms as well as the reservoir host and vector.

How a stealth pathogen may prolong your chronic illness

In individuals with strong immune systems, Bartonella infection is often mild or asymptomatic. However, in those with an impaired immune system, Bartonella can wreak havoc on the body.

In fact, Bartonella henselae was discovered in the 1990s during the AIDS epidemic. Because the HIV virus causes an acquired immune deficiency, these patients were extremely susceptible to new infections and reactivation of latent infections. In this patient population, Bartonella caused a distinctive skin lesion called bacillary angiomatosis (BA), and a type of liver disease called peliosis hepatis. (Breitschwerdt, E.B., 2017)

Advanced, disseminated disease is more likely to occur in immunocompromised patients or those taking immunosuppressive drugs. Without proper treatment, the infection can spread systemically throughout the body. The result is sometimes fatal.

When the co-infection becomes the main infection

Data from multiple animal studies shows that Borrelia burgdorferi suppresses the immune system. (Buffen K, et al., 2016; Tracy KE, Baumgarth N., 2017)

This makes me wonder. How many people with chronic Lyme disease had a latent Bartonella infection that was re-activated when their immune system became impaired?

I believe this was the case with my daughter. We live on a farm with lots of animals, including cats. Veterinarians, cat owners, and people who live or work on farms are at increased risk for Bartonella.

It wasn’t until my child became deathly ill after contracting Ehrlichia chaffeensis that her Bartonella symptoms began.

The symptoms that stood out were the constant migraine/headache, memory loss, bone pain, painful soles of feet, relapsing fever, insomnia, nighttime hallucinations that made everything look like Whoville, POTS, skin marks (striae) that resembled stretch marks, swollen lymph nodes, and an immune system so impaired it led to a temporary misdiagnosis of HIV. What a horrific experience for all of us!

Diagnosis & Treatment

Because Bartonella may hide inside of cells and only emerge periodically, you may need to test multiple times to find a confirmatory diagnosis. And in patients who are immunocompromised, the test may not turn positive until after treatment has begun.

Research led by Ricardo Maggi, Ed Breitschwerdt and colleagues has led to the development of a new digital PCR that is much more sensitive to Bartonella. Even still, Dr. Maggi recommends running multiple types of tests (IFA serology, PCR, culture, and microscopy).

According to Dr. Joseph Burrascano, one should consider bartonellosis when symptoms persist after treatment for Lyme disease. Especially when the neurological symptoms are out of proportion to the common symptoms of disseminated Lyme disease.

Just as with Lyme disease, the longer Bartonella goes untreated, the more difficult it is to treat. Furthermore, the standard treatment for Lyme (doxycycline) is ineffective against Bart. As Dr. Breitschwerdt famously said, “You cannot float humans or horses in enough doxycycline to kill this bacteria.”

According to the CDC: “A number of antibiotics are effective againstBartonella infections, including azithromycin, penicillins, tetracyclines, cephalosporins, aminoglycosides, and macrolides. More than one antibiotic is often used. Consult with an expert in infectious diseases regarding treatment options.”

Dr. Burrascano says, treating Bartonella-like organisms “can be difficult, as drug resistance can rapidly develop to macrolides and fluoroquinolones when used as a single agent and solo courses of tetracyclines are ineffective.”

Moving forward with Bartonella research

In 2021, a new Bartonella Research Consortium was formed with a $4.8 million grant from The Steven & Alexandra Cohen Foundation.

The consortium includes Ed Breitschwerdt and Ricardo Maggi of North Carolina State University, Monica Embers of Tulane University, and Timothy Haystead of Duke University, who is continuing the work of the late Dr. Neal Spector.

The team is actively working towards creating a targeted treatment for bartonellosis and quickly getting the drug to the marketplace for use in both animals and humans.

It’s time medicine moves beyond the one-pathogen-one-disease model. Let’s face it, ticks are full of toxic soup. Because each pathogen interacts with the host in unique ways, extensive research is needed to understand all factors surrounding co-infections and Lyme disease. (Moutailler S, et al., 2016)

Understanding the complex nature of these pathogens, how they impact the immune system, and how other bacterial and viral factors shape illness, will be key in improving public health. (Cheslock, M. A., & Embers, M. E., 2019)

It’s time for the CDC, NIH, HHS, the Tick-Borne Disease Working Group and other researchers to start looking deeper into the prevalence of Bartonella infections–not just in patients with Lyme disease but in all patients with poorly-defined chronic illnesses.

FAQs

Is Bartonella related to Lyme disease? ›

HARD SCIENCE ON LYME: Research Finds Bartonella Transmission from Tick to Host. This research is very important to patients with Lyme disease because it confirms that the transmission of bartonella from ticks may produce Bartonelleosis.

Is Bartonella common? ›

Bartonella is one of the most common types of bacteria in the world. While most people are familiar with the Bartonella infection known as Cat Scratch Disease, species of Bartonella can cause other diseases too.

Can you ever get rid of Bartonella? ›

Although in most patients the disease resolves spontaneously within 2-4 months without treatment, in people with severe cases and/or patients with a suppressed immune system, such as HIV/AIDS, antibiotic treatment is recommended.

Can you have Bartonella for years? ›

Cats infected with Bartonella usually have asymptomatic bacteremia that can last for many months. A transmission to humans occurs directly from a cat scratch and may occur through the cat flea Ctenocephalides felis [3,9,26,27]. There has been some debate on whether the bacteria can be transmitted from a cat's bite.

Frequently asked questions

To date, we have tested 220 adult lone star ticks from 23 counties and 94 of those were positive for ehrlichiosis.. Cass County 7 tested, 3 positive for ehrlichiosis. Jackson County 10 tested, 6 positive for ehrlichiosis. Taney County 10 tested, 4 positive for ehrlichiosis. Shannon County 10 tested, 5 positive for ehrlichiosis. Lone star ticks (Amblyomma americanum): Texas County 9 tested, 7 positive for ehrlichiosis. Howell County 10 tested, 7 positive for ehrlichiosis. Adair County 9 tested, 4 positive for ehrlichiosis. Boone County 10 tested, 3 positive for ehrlichiosis. Callaway County 10 tested, 7 positive for ehrlichiosis. Jefferson County 10 tested, 4 positive for ehrlichiosis.

After conducting the largest survey of patients with POTS Syndrome in history, the results are finally in. Learn about POTS from the patient's perspective. It will inspire you to take action.

This guide – which we’re calling the POTS Center – is intended to be the most comprehensive online resource on POTS.. POTS is a form of dysautonomia that affects the flow of blood through the body, thereby causing dizziness when standing.. According to our survey, fatigue (95.2%) is the most common symptom – which isn’t surprising considering the commonality of POTS and Chronic Fatigue Syndrome (CFS).. Dizziness when standing is the second most common symptom (95.2%), followed by brain fog ( 93.1%), and heart palpitations (92.0%).. People suffering from POTS can find themselves in a frustrating cycle – they won’t feel better unless they’re active, yet they don’t’ have the energy to be active.. Various types of doctors can diagnose POTS, but our survey found that cardiologists most commonly diagnose the disease.. Nonetheless, it is currently far too difficult for patients with POTS to receive proper diagnosis and treatment.. Another notable finding in our survey is the amount of time patients can suffer from often debilitating symptoms before receiving proper treatment.. While we don’t know the reason it’s so difficult for patients to receive proper treatment for POTS, we can conclusively say that it’s not because these patients aren’t trying to understand the cause of their symptoms.. You can find scientifically-supported treatments and the corresponding literature in our section detailing POTS treatments.. Secondary causes of POTS are when another disease or condition cause the disease.. Disease

A personal story and a full breakdown of how one of our contributors used nebulized antioxidants and minerals to help recover from COVID-19...

Using a nebulizer with a compounded blend of glutathione, NAC and magnesium sulfate helped my respiratory constraints tremendously.. As both a health and wellness practitioner and someone who recovered from a long stint with COVID, I highly recommended having a nebulizer as a part of your household medical care kit, alongside your thermometer, oxygen saturation meter (pulse oximeter) and a wrist blood pressure device.. A nebulizer is a small piece of medical equipment that is used to administer liquid medication or supplements, directly into the lungs and respiratory system.. Typically, nebulizers are used for acute respiratory distress (asthma attacks), wheezing; chest tightness; severe cough; breathlessness; lung infections, cystic fibrosis; bronchiectasis; COPD (chronic obstructive pulmonary disease); lung injury; shortness of breath; sinus & respiratory infections; children and adults who have a hard time taking oral medication and supplements or inhalers.. Nebulized glutathione has been highly effective in treating the respiratory issues listed above, including my own during with COVID.. In addition to the benefits of glutathione alone, the combination of NAC and glutathione together in a nebulized treatment has also been shown to be effective for dissolving the mucous in sinus and respiratory infections, as well supportive for neurotransmitter balancing for issues related to addiction, anxiety and depression.. With NAC, Glutathione and magnesium, there are typically little to no side effects as opposed to side effects from medication.

The critical nature of the microbiology laboratory in infectious disease diagnosis calls for a close, positive working relationship between the physician/advanced practice provider and the microbiologists who provide enormous value to the healthcare team. This document, developed by experts in laboratory and adult and pediatric clinical medicine, provides information on which tests are valuable and in which contexts, and on tests that add little or no value for diagnostic decisions.

This document presents a system-based approach rather than specimen-based approach, and includes bloodstream and cardiovascular system infections, central nervous system infections, ocular infections, soft tissue infections of the head and neck, upper and lower respiratory infections, infections of the gastrointestinal tract, intra-abdominal infections, bone and joint infections, urinary tract infections, genital infections, and other skin and soft tissue infections; or into etiologic agent groups, including arthropod-borne infections, viral syndromes, and blood and tissue parasite infections.. Because result interpretation in microbiology depends entirely on the quality of the specimen submitted for analysis, specimen management cannot be left to chance, and those that collect specimens for microbiologic analysis must be aware of what the physician needs for patient care as well as what the laboratory needs to provide accurate results, including ensuring that specimens arrive at the laboratory for analysis as quickly as possible after collection ( Table 1 ).. Two sets of aerobic and anaerobic bacterial/candidal blood cultures and ESR and CRP should be obtained; in addition, Brucella blood cultures and serologic tests should be obtained in those in areas endemic for brucellosis, fungal blood cultures in those with relevant epidemiologic or host risk factors, and, as with other types of osteomyelitis, a purified protein derivative test or interferon-γ release assay may be considered in those at risk for tuberculosis (acknowledging a risk of both false-positive and false-negative results).. Culturing only urines that have tested positive for pyuria, either with a dipstick test for leukocyte esterase or other indicators of PMNs, may increase the likelihood of a positive culture, but occasionally samples yielding positive screening tests yield negative culture results and vice versa [186].. It is strongly recommended that initial cultures focus on common pathogens, with additional testing being reserved for uncommon or rare infections associated with special circumstances (eg, detection of Vibrio spp following saltwater exposure) or patients with chronic manifestations of infection or who do not respond to an initial course of therapy.
