Can you sense the uncertainty here? They are not even sure how many species are making people sick. And they only allude to "uncomplicated " cases, without fully addressing CSD with complications. If tick-borne Bartonella is not resolved by the infected person's immune system...if abx cannot be relied on always to eradicate it, and it progresses...what exactly happens? What is the trajectory of symptoms after five years? Ten? Twenty? What is the import to the immune system that, after a while, must be the definition of beleaguered?
Same questions applies to those infected via ticks with Babesia. At least with Babesia, even the hardliners, when pressed, will admit one can never be certain all the Babesia are gone.
Ditto, of course, with late stage Bb - where can it eventually lead? Who is studying this, and to what degree? They only figured out it was a spirochete in the 80's. How many individuals are seeing this disease run its course? I think the answer is more than anyone would find conscionable.
Combine the B's, they arguably form quite the toxic cocktail. A case of the whole being greater than the sum of its parts, but with a very nasty twist.
This doesn't even touch on the other tick-borne pathogens and parasites.
