I've seen that some websites and others recommend that you keep ticks - but I'm not
sure how helpful it is. Perhaps they can test the tick for the diseases but I think it would
be more for epidemiological (the geographical distribution and prevalence of diseases)
purposes rather than for getting the antibiotics right as I'm sure they'd just give you a
broad spectrum antibiotic to get rid of the nasties rather than flapping about exactly
which organism might be being dealt with.
Having said that I'm not a doc, so they might do something entirely diffferent
I kept my ticks out of curiosity and so that I can prove to the doctor that I'd been bitten.
Just in case hehe.
To the best of my knowledge no action would be taken in the absence of symptoms
and it was low-risk etc. etc. Perhaps if it was high-risk and you were not in the best
of health there might be some preventative antibiotic use but I'm assuming this is
pretty unlikely and in fact have strayed quite beyond my domain of knowledge here
