I like this one, because it shows others are actually doing real research,
Which will inevitably take the myopic control
Away from the little group who thinks they discovered it in the 70;s and
Who have been somewhat responsible for the havoc it let loose on unsuspecting innocent people being
Infected over the last several decades
Due to ignorance in medical community and poor, poor quality of testing. And for some reason, I cannot fathom,
Keeping this secret from the public. I know if I'd have known about the poor quality of testing back,
This disease would not have taken me out the way it did.
What I am confused about though, is how some European scientists and papers are considering lyme a viral thing, and saying that there is a vaccine for it.
Whatever the case, it seems bigger research is being done, and this can only be good.
ScienceDaily (June 30, 2008) -- Researchers at the University of Bath have discovered that a bacterium that causes
Lyme disease originated in Europe, rather than in North America as previously thought.
The bacterium responsible for Lyme disease, Borrelia burgdorferi, originated in America, or so researchers thought.
Now, however, a team from the University of Bath has shown that this bug in fact came from Europe, originating from before the Ice Age.
By understanding the origins of the bacterium and how it has evolved so far researchers hope to be able to predict how it will continue to develop, and so find ways to prevent its spread. In the study, researchers from the University of Bath and
colleagues from the UK and USA studied the evolutionary history of the bacteria by looking at the sequences of eight so-called 'housekeeping genes', which evolve very slowly. They analysed
64 different samples taken from infected humans and ticks in Europe and America.
In all, 33 different combinations of the housekeeping genes were found. The study's findings appear to show that Borrelia
burgdorferi originated in Europe but that the species has been present in North America for a long time. The researchers suggest its re-emergence there in the 1970s occurred after the
geographic territory of the tick that carries the bacteria expanded, for example through the restoration of woodland. Lyme disease is a growing problem in Europe, Asia and - in
particular - North America, where it is now the most common vector-borne disease. The disease was named after Old Lyme, Connecticut, the site of a number of cases in the 1970s. There
is no vaccine for the infection, which can cause arthritis and problems with the nervous system and heart if left untreated. Image: The blacklegged tick Ixodes pacificus, a known vector for
