I say “LYME DISEASE,”

you say….

*Borreliaburgdorferi

Other Borrelia

Babesia

Bartonella

Ehrlichia

Anaplasma

Mycoplasma

Lyme disease is an acute infectious disease, transmitted by nymph stage deer ticks, caused by one species of a

specific bacterium named Borreliaburgdorferi

“Hard to catch and easy to cure”

Tick must be attached for a minimum of 36 hours to transmit Lyme disease…

Current IDSA/CDC “Standard of Care”

Peer-reviewed evidence

NOT included in the

IDSA/CDC guidelines

Burgdorfer: transmission

time for Borrelia is

variable.

Other TBDs transmitted

quickly; viruses in 15 min.

Borrelia may be sexually

transmitted.

Borrelia, Babesia,

Anaplasma are

transfusion transmitted.

Lyme disease is an acute infectious disease.

Current IDSA/CDC “Standard of Care”

Peer-reviewed evidence

NOT included in the

IDSA/CDC guidelines

Lyme disease may

be an acute disease.

Lyme disease may

also be a chronic

disease.

A single “FRONTAL” pathogen, Borreliaburgdorferi, is responsible for Lyme disease symptoms.

Ticks carry and

transmit multiple

“STEALTH” microbes.

People infected with

multiple pathogens

have more severe

disease.

Current IDSA/CDC “Standard of Care”

Peer-reviewed evidence

NOT included in the

IDSA/CDC guidelines

Diagnostic algorithm (ACP) includes patient history of tick bite, “bulls-eye” rash, AND “laboratory evidence” of infection (usually this means a “two-tier” system of antibody based blood tests for Borreliaburgdorferi ONLY)

Current IDSA/CDC “Standard of Care”

Peer-reviewed evidence

NOT included in the

IDSA/CDC guidelines

Current diagnostic criteria

EXCLUDE any form of the

disease that does not meet the

ACP/CDC/IDSA algorithm

Therefore, you may not be

diagnosed with Lyme disease,

EVEN IF YOU HAVE IT, if:

No “bulls-eye” at tick bite site

“First tier” test doesn’t meet a

threshold level

“Second-tier” test doesn’t have

enough “bands”

You were infected with more

than one microbe by the tick

Most infections resolve after short-term antibiotic treatment; 5% of patients may develop post-txsequelae that are “autoimmune.”

CDC survey - 61% require

more than recommended

antibiotic treatment.

30 – 50% have chronic

symptoms persisting after

antibiotics.

Stealth pathogens are highly

adapted survivors so

persistent infection may be

the cause.

spirochetes shown in most

recent study.
