| Tóm tắt: | The aim of this monograph is to provide a general overview of the geographical distribution
of various tick species which have proven their involvement in the transmission of the patho-
gens causing animal diseases and zoonoses in Europe, the Middle East and the Mediterranean
basin. As blood-feeding parasites, ticks are able to transmit to their hosts a wide variety of
pathogens which may cause tick-borne infections and tick-borne diseases (TBDs) that affect
wild and domestic animals, including companion animals. The transmission of pathogens
among ticks may occur transovarially, i.e. the pathogen is transmitted via the eggs from females
to their offspring, trans-stadially from larva to nymph and/or from nymph to adult, and vene-
really during copulation from male to female tick. Vectorial competence is the overall ability of
a vector tick species to transmit a pathogen to a range of receptive vertebrate hosts in a given
location at a specific time. The TBDs usually are geographically distributed within the range of
their vectors. Some of these infections/diseases can give clinical signs which can be severe (in
the acute phase) but can also present as subclinical forms (mainly in endemic areas) in animals or
humans. Furthermore, co- infection with different pathogens can occur in the same vertebrate
animal when the same tick species transmits more than one pathogen (e.g. Hepatozoon canis,
Ehrlichia canis and Anaplasma platys transmitted by Rhipicephalus sanguineus), or when two or
more tick species infest an animal or human at the same time (Belongia, 2002; Stan ´czak et al.,
2002; Bremer et al., 2005; Halos et al., 2005; Swanson et al., 2006). TBD co-infections by ticks are
frequent in companion animals living in endemic areas and this may often impair an appropri-
ate aetiological diagnosis (EFSA, 2007). |
