Bartonella organisms have been detected in ticks, fleas, chiggers, dogs, cats (Dr. Klinghardt states 90% of cats), sheep keds, mice, rats, cattlevoles, pigs, human wombshuman body lousepumavole ear mites, lice, flies, sand flies, bobcats, whales, elk, rabbits, animal saliva, mountain lionshuman saliva, dust mites, dolphins, bush rats, striped skunks, raccoons, mountain lions, bats, leeches, bed bugs, mosquitoes, monkeyswoyliesbandicoots, mardosdeer, squirrels, coyotes, red fox, grey fox, gerbil fleasgolden jackals, Libyan birdsrock hyraxes, southern white-breasted hedgehogs, porpoises, Cairo spiny mice, Tristram's jirds, house mice and possibly spiders

Research is needed to determine if there are additional carriers, transmitters and more unidentified species of Bartonella.  Physicians need to be trained to look for Bartonella infections in their patients and accurate tests must be developed to detect Bartonella species in both animals and humans.

A Serious Disease With
Potentially Serious Consequences

Bartonella henselae and Bartonella quintana, sometimes referred to as “cat-scratch” and “trench” fever respectively, are two types of intracellular gram negative bacteria which can cause severe, chronic health issues and sudden death.  Maryland residents are at high risk for exposure to various Bartonella bacteria.     

Possible signs and symptoms-  Typically a gradual onset of symptoms.  Central nervous system symptoms (muscle twitches, insomnia, mood swings, anxiety, antisocial behavior, tremors, irritability and seizures) are often more prominent and severe than other symptoms.  

Fatigue, dizziness, stiff legs, pain in feet (especially bottoms of feet- worse early in the morning), sweats, restlessness, myalgias, migrating pain (can be extreme) in and around joints,  heart attacks, heart valve problems, endocarditis (mortality 25%), cardiomegaly, strokes, skin rashes (including "stretch mark" like rashes), skin tags, burning and crawling sensations.  

Aseptic meningitis, encephalopathy, fever (often low-grade), panic attacks, liver or spleen abnormalities, low-grade fever, abscesses, hot flashes, muscle cramps, confusion, abdominal pain, hepatitis, seizures (mild to severe), numbness in hands, rage, depression, misophonia, difficulty walking, facial numbness, wandering (usually unilateral) joint pain, urinary disorders, or arthritis can be present.  

Tender sub-cutaneous nodules may appear along the outer thigh, triceps shins and other areas of the extremities. 

Some patients experience acute and relapsing symptom patterns, painful headaches, lymphadenopathy, GI symptoms (gastritis, abdominal pain), cognitive dysfunction, joint swelling, CNS lesions, red splotches or slightly raised red spots on skin, lymph node swelling, skin manifestations (acne, stretch marks, subcutaneous nodules) and spider veins.

Patients may also experience bone pain- especially in shins (Bartonella quintana, aka shin bone fever) and along the rib cage, chest wall pain, ice-pick pain sensations in head, mild sore throat, bladder inflammation or IC, softening of bone, bone infections, radiculitis, difficulty swallowing, transverse myelitis, polyneuropathy, slurred speech, elevated liver enzymes, gall bladder dysfunction, crusty scalp, respiratory complications, personality disorders, bipolar disorder and irregular pulse.  

Bartonella can cause an array of eye related problems such as raccoon eyes (dark circles under/around eyes)dry eyes, conjunctivitis, neuroretinitis and a distortion or loss of vision.

Bartonella symptoms may wax and wane or appear to be in remission. Symptoms may return quickly if treatment is discontinued too soon.  See the "Ask The Experts" 2016 article with more Bartonella symptoms and photos. 

If not treated properly in the early stages, Bartonella can become a disabling condition that can be expensive and difficult to treat.  Bartonella has been misdiagnosed or mistaken for vasculitis, breast cancer, hepatitis, Kaposi’s sarcoma, splenic lymphoma and a variety of neurological and psychiatric illnesses.  People infected with Bartonella may also be coinfected with one or more of the 300 plus known Lyme strains, viruses and/or additional tick or vector borne diseases.

Testing Information 

Galaxy Lab- Galaxy Lab tests for at least 17 species of Bartonella.  They also test for at least 30 species of Ehrlichia, Rickettsia (spotted fevers) and Babesia. See which species are tested for each genus HERE.

Treatment Information

There is no one-size-fits-all treatment protocol for Bartonella infections.  Doxycycline, rifampin, ciprofloxacin, erythromycin, tetracycline, clarithromycin, azithromycin or combinations of antibiotics have been used with varying degrees of success.  Retreatment is often necessary in long standing cases.

QUOTE-  "The drug of choice to treat BLO is levofloxacin. Levofloxacin is usually never used for Lyme or Babesia, so many patients who have tick-borne diseases, and who have been treated for them but remain ill, may in fact be infected with BLO. 

Treatment consist of 500 mg daily (may be adjusted based on body weight) for at least one month. Treat for three months or longer in the more ill patient. It has been suggested that levofloxacin may be more effective in treating this infection if a proton pump inhibitor is added in standard doses.

Another subtlety is that certain antibiotic combinations seem to inhibit the action of levofloxacin, while others seem to be neutral. I advise against using an erythromycin-like drug, as clinically such patients do poorly. On the other hand, combinations with cephalosporins, penicillins and tetracyclines are okay. 

Alternatives to levofloxacin include rifampin, gentamicin and possibly streptomycin. A very recent article suggests that prior use of quinine-like drugs including atovaquone (Mepron, Malarone) may render Levaquin less effective. Therefore, in a co-infected patient, treat the BLO before you address Babesia species."

Special note- Bartonella bacteremia has been detected in 89% beef cattle tested from Oklahoma and 17% of dairy cattle from California.  Recently, a study by the College of Veterinary Medicine at North Carolina State University reported finding one or more species of bartonella in 82.4% of cattle they tested.

UPDATE- July 2016-  Note from Lyme treating ophthalmologist:  "I usually see Bartonella as the cause of the most severe eye issues. Make sure to take lutein and zeaxanthin and fish oil to further protect your eyes."  Zeaxanthin and lutein information- click here.
