The aim of the present study was to provide a preliminary insight into
the diversity of tick-borne pathogens circulating at the domestic
host-tick interface in Romania. For this, feeding and questing ticks
were analyzed by real-time polymerase chain reaction (PCR) for the
presence of Anaplasma phagocytophilum, Anaplasma platys, Ehrlichia
canis, Borrelia burgdorferi sensu latu, and by PCR and subsequent
sequencing for Rickettsia spp., Babesia spp. and Theileria spp.
A total of 382 ticks, encompassing 5 species from 4 genera, were
collected in April-July 2010 from different areas of Romania; of them,
40 were questing ticks and the remainder was collected from naturally
infested cattle, sheep, goats, horses or dogs.
Tick species analyzed included Ixodes ricinus, Dermacentor marginatus,
Hyalomma marginatum, Rhipicephalus bursa, and Rhipicephalus sanguineus.
Four rickettsiae of the spotted fever group of zoonotic concern were
identified for the first time in Romania: Rickettsia monacensis and
Rickettsia helvetica in I. ricinus, and Rickettsia slovaca and
Rickettsia raoultii in D. marginatus.
Other zoonotic pathogens such as A. phagocytophilum, Borrelia afzelii,
and Babesia microti were found in I. ricinus. Pathogens of veterinary
importance were also identified, including Theileria equi in H.
marginatum, Babesia occultans in D. marginatus and H. marginatum,
Theileria orientalis/sergenti/buffeli-group in I. ricinus and in H.
marginatum and E. canis in R. sanguineus.
These findings show a wide distribution of very diverse bacterial and
protozoan pathogens at the domestic host-tick interface in Romania, with
the potential of causing both animal and human diseases.
