In this monograph are analysed the principal infections transmitted by tick
s and particularly those interesting Europe and North America. Besides the
main species of these arthropods are described in consideration of their ch
aracteristics and geographic diffusion. In particular the infections caused
by Borrelia genus and tick born encephalitis virus are treated more exhaus
tively in consideration of their potential severity and because the diagnos
is of these infections is sometimes difficult. However also the main ricket
tsial infections trasmitted by ticks are reported together the hemorragic f
evers transmitted by such arthropods. In particular it is exhaustively anal
ysed the Mediterranean tick fever in consideration of its presence in some
regions of Italy and of the wrong opinion of considering this pathology not
very severe. Lastly has been included a treatment about some emergent infe
ctions transmitted by ticks, like as the ehrlichiosis and babesiasis, but a
lso the mention of tularaemia that can be considered a re-emergent infectio
n, also in consideration of the epidemic focus now present in Kossovo. The
above-mentioned pathologies are analysed also as regards the laboratory dia
gnosis (direct and serologic methods), the therapeutic treatment and the pr
ophilaxis, both directed against the arthropods vectors and that of individ
ual type, employing also some vaccines, when disposable.
