A recent study finds that 46% of people with ME/CFS were unknowingly infected with one of these two pathogens...🧵
Fifty people experiencing chronic fatigue and neurological symptoms similar to those in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) were tested for evidence of:
- Bartonella (a bacterium often spread by fleas or ticks)
- Babesia (a tick-borne parasite)
Here is what they found.
Researchers detected infections with:
- Babesia (a tick-borne parasite) in 10 individuals (20%),
- Bartonella (a bacterium often spread by fleas or ticks) in 11 (22%),
- and both in 2 (4%).
Overall, nearly half (46%) showed evidence of at least one pathogen in their blood.
These infections are known to cause:
- anxiety
- prolonged fatigue
- neurological issues
- and irritability even without classic acute signs
They identified the different species using PCR tests on blood and enriched blood cultures.
However, PCR tests can yield false positives, underscoring the need for a more robust study that screens for pathogen-specific antibodies.
Do a subset of patients with ME/CFS-like symptoms suffer from a Babesia or Bartonella infection?
