Serum samples from 123 cattle, 95 wild boars, and 43 deer (red deer, roe deer, and fallow deer) from the territory of eastern Poland were examined by the ELISA for the presence of specific antibodies against tick-borne encephalitis virus (TBEV). The rates of positive response in the animals were 4.1%, 16.8%, and 11.6%, respectively. Examination of 37 blood samples from deer with RT-PCR revealed only one positive result in a roe deer (2.7%). The relatively high serologic response rate in wild boars was due to a very high response rate (35.7%) in the Chełm district, which accounted for 94% of the total positive results. These findings seem to indicate that the Chełm district is most probably an endemic area of TBEV.

Rickettsia spp. transmitted by ticks are classified mostly in the Spotted Fever Group Rickettsiae (SFGR). Numerous species of this group have been identified in Eurasia as emerging pathogens, but still little is known about their occurrence, effects on human health, and co-incidence with other tick-borne pathogens. The aim of the presented study was to determine the prevalence of Rickettsia spp. in adult Dermacentor reticulatus (Acari: Amblyommidae) ticks collected in Lublin province of eastern Poland using the PCR method. The infection rate of D. reticulatus with Rickettsia spp. was 53.0%. All except one rickettsial isolates showed 100% homology with Rickettsia raoultii. A high prevalence of R. raoultii in Dermacentor reticulatus ticks from eastern Poland suggests that the SFGR species should be considered as potential causative agents of tick-borne diseases in this area.
