This week, we welcome Dr. Ed Breitschwerdt, a specialist in internal medicine and infectious disease at North Carolina State University. Dr. Breitschwerdt has
received funding from the Canine Health Foundation for various infectious diseases including Bartonella spp. In this podcast, Dr. Breitschwerdt describes
Bartonella is Everywhere, So Why Don’t We Know More About It? | North Carolina Health News, 23 Jan 2014 [cached]
Ed Breitschwerdt, a professor of veterinary sciences at North Carolina State University, keeps waiting for the tipping point. For the last 30 years, Breitschwerdt has been studying Bartonella, a genus of bacteria found in animals, ticks and humans.
"It's frustrating," said Breitschwerdt.
Though people have known of cat scratch disease - the most public of the human diseases caused by Bartonella infection - for more than 100 years, Breitschwerdt said he's convinced that Bartonella is the stealth cause of many neurological, inflammatory and chronic diseases in humans.
And, unlike Lyme disease, another tick-borne illness that can cause an array of distressing symptoms, Bartonella is right in the backyard of most North Carolinians.
"It's a medically important bacteria in animals and humans in the state. If you took every stray cat along the coast of North Carolina, three quarters of them would have Bartonella," said Breitschwerdt. "That's because the bacteria is commonly transmitted to animals by fleas."
He said that, historically, vets have considered common cat flea a nuisance but have under-appreciated it as a disease vector. For several years, Breitschwerdt has seen all sorts of animals and mites, ticks, fleas and even spiders test positive for Bartonella.
"Animals are the primary reservoir for the Bartonella species," he said.
Breitschwerdt has worked with the One Health Commission, a collective that looks at the links between environmental, human and animal health. Though his professional and personal life has been guided by his care for animals, his most recent work is geared towards detecting and treating Bartonella infection in humans.
The recovery process
The Hoppers contacted Breitschwerdt at a fortunate time: He was developing new human diagnostic method for Bartonella.
"You cannot float humans or horses in enough Doxycycline to kill this bacteria," said Breitschwerdt.

"People are tested several times, but Bartonella can hide in the body," Breitschwerdt said.
"I often talk with veterinarians who have these vague complaints - who say they've been sick for weeks or months," said Breitschwerdt.
Many of the vets receive diagnoses of Lyme disease, chronic fatigue, rheumatoid arthritis, or are sent to a psychiatrist and told their symptoms are untreated depression. But Breitschwerdt cautions them to get tested for Bartonella.
Breitschwerdt has ventured into industry with Galaxy Diagnostics, a company he founded to offer Bartonella testing kits to doctors.
The determination of Dr. Breitschwerdt and his research and assistance and kindness by Julie were a much needed ray of hope during a frightening time.
Great article and side note Dr. Breitschwerdt is very approachable and helpful. I don't live in North Carolina - I am in Texas and he answered all emails personally.

So Sigmon called Dr. Ed Breitschwerdt, a veterinary researcher at N.C. State University.
Sigmon, herself a vet, knew Breitschwerdt studied tick-borne diseases.
Sigmon recalls asking Breitschwerdt.
In reaching out to Breitschwerdt, Sigmon turned to a man who may know a hidden cause behind many chronic human ailments that often aren't recognized as infections transmitted by animals and insects.
At the heart of Breitschwerdt's research is a pathogen carried by insects - a bacteria known as Bartonella. Spread by biting pests such as fleas, lice, sandflies and possibly ticks, Bartonella are difficult to detect in human blood. As a result, Breitschwerdt thinks the bacteria are taking an unacknowledged toll on human health.
"I believe it's a silent epidemic," says Breitschwerdt, who is also an adjunct professor in infectious diseases at Duke University Medical School.
His belief is based on his own patients - the cats, dogs, rabbits, cows and other animals that harbor Bartonella in their blood. With so many insects spreading the bacteria to so many animals, he contends, the bugs are certain to readily infect humans.
Breitschwerdt suspected a Bartonella infection was behind Jason Sigmon's headaches.
Mr. R, 38, had worked as a physician assistant in the emergency department (ED)of a small hospital in the Midwest for nine years. He often recognized many of the patientsin the waiting room -"repeat customers" he termed them.
Mrs. K was one of them. A divorced mother of four rambunctious boys ranging from 11 to 17 years old, she was frequently at the ED with one son or another after a sports injury, a fall from a tree, or a bout of strep throat or flu.
Dr. Edward Breitschwerdt, professor of internal medicine at NC State's College of Veterinary Medicine and adjunct professor of medicine at Duke University, studied the bacteria Bartonella to determine how long these bacteria induce active infection in humans.
The most commonly known Bartonella-related illness is cat scratch disease, caused by B. henselae, a strain of Bartonella that can be carried in a cat's blood for months to years. Cat scratch disease was thought to be a self-limiting, or "one-time" infection; however, Breitschwerdt's previous work discovered cases of children and adults with chronic Bartonella infections - from strains of the bacteria that are found in cats (B. henselae) and dogs (B. vinsonii subsp. berkhoffii).
In a study published in the September volume of the Journal of Clinical Microbiology, Breitschwerdt and colleagues from the Duke University Medical Center and the Centers for Disease Control and Prevention in Atlanta were able to detect one or more strains of Bartonella in blood samples from six patients suffering from a broad spectrum of neurological and neurocognitive abnormalities, including chronic migraines, seizures, memory loss, disorientation and weakness. All of the patients in the study had both frequent tick exposure and significant animal exposure - some were veterinarians, others had grown up on farms or had occupations that kept them outdoors - and all of them suffered from chronic, debilitating neurological problems.
The patients were treated with antibiotics, and three of them saw marked improvement. In the other cases, improvements were minimal or short-term. Breitschwerdt believes that his research offers hope - perhaps the identification of a specific infectious cause of chronic neurological disease and another potential avenue of treatment - for what could be a significant segment of the population.
"Bartonella has been described by some scientists as a 'stealth pathogen,'" he says. "Our research could lead to the elimination of what may be a silent and currently unrecognized epidemic among humans."

Edward B. Breitschwerdt, DVM Professor of Medicine and Infectious Diseases
Dr. Edward B. Breitschwerdt is a professor of medicine and infectious diseases at North Carolina State University College of Veterinary Medicine. He is also an adjunct professor of medicine at Duke University Medical Center, and a Diplomate, American College of Veterinary Internal Medicine (ACVIM). Dr. Breitschwerdt directs the Intracellular Pathogens Research Laboratory in the Center for Comparative Medicine and Translational Research at North Carolina State University. He also co-directs the Vector Borne Diseases Diagnostic Laboratory and is the director of the NCSU-CVM Biosafety Level 3 Laboratory.
A graduate of the University of Georgia, Breitschwerdt completed an internship and residency in Internal Medicine at the University of Missouri between 1974 and 1977. He has served as president of the Specialty of Internal Medicine and as chairman of the ACVIM Board of Regents. He is a former associate editor for the Journal of Veterinary Internal Medicine and was a founding member of the ACVIM Foundation.
Breitschwerdt's clinical interests include infectious diseases, immunology, and nephrology. For over 20 years, his research has emphasized vector-transmitted, intracellular pathogens. Most recently, he has contributed to cutting-edge research in the areas of animal and human bartonellosis. In addition to authoring numerous book chapters and proceedings, Dr. Breitschwerdt's research group has published more that 300 manuscripts in peer-reviewed scientific journals. In 2012, he received the North Carolina State University Alumni Association Outstanding Research Award and in 2013 he received the Holladay Medal, the highest award bestowed on a faculty member at North Carolina State University
