Reactions to argasid
tick bites by island residents on the Great Barrier Reef.
turicatae, both relapsing fever agents transmitted by argasid
ticks, and for B.
Therefore, tick-borne transmission studies were performed with an ixodid (Ixodes ricinus) and an argasid tick species (Ornithodoros moubata).
We investigated an argasid tick species and an ixodid tick species for their competence as vectors and reservoirs of the New York strain (NY99) of WNV.
Our study represents the first unequivocal report of co-feeding transmission by an argasid tick species.
hermsii, is transmitted by Ornithodoros hermsi, a fast-feeding argasid tick.
Two groups of spirochetes stand out among these tick-borne species because of their prevalence as human pathogens: Lyme disease spirochetes, transmitted by the relatively slow-feeding ixodid (hard) ticks of the genus Ixodes, and relapsing fever spirochetes, transmitted by the fast-feeding argasid (soft) ticks of the genus Ornithodoros (Figure 1).
Relatively few studies have examined the distribution of relapsing fever spirochetes in tissues of argasid ticks.
They draw on papers published from 2000 to 2010 to describe the factors behind the emergence of tick-borne diseases; the basic biology of 25 key tick species in the regions and their life cycles, geographical distributions, and significance as vectors, with photos; factors responsible for the spread and distribution of ticks, including climate, land use, and animal movement; tick-borne infections; the geographical distribution of tick-borne pathogens and the vector ticks; and the surveillance and control of ticks and tick-borne diseases, including sampling methods and control options for ixodids and argasids
At least 21 species of hard ticks and 3 argasids
are recognized in mainland Britain and its islands (33).
