Popis: Purpose The aim of the study is to assess anti-Coxiella burnetii antibodies presence in inhabitants of north-eastern Poland, to assess the risk of Q fever after tick bite and to assess the percentage of co-infection with other pathogens. Methods The serological study included 164 foresters and farmers with a history of tick bite. The molecular study included 540 patients, hospitalized because of various symptoms after tick bite. The control group consisted of 20 honorary blood donors. Anti-Coxiella burnetii antibodies titers were determined by Coxiella burnetii (Q fever) Phase 1 IgG ELISA (DRG International Inc. USA). PCR was performed to detect DNA of C. burnetii, Borrelia burgdorferi and Anaplasma phagocytophilum. Results Anti-C. burnetii IgG was detected in six foresters (7.3%). All foresters with the anti-C. burnetii IgG presence were positive toward anti-B. burgdorferi IgG and anti-TBE (tick-borne encephalitis). Anti-C. burnetii IgG was detected in five farmers (6%). Four farmers with anti-C. burnetii IgG presence were positive toward anti-B. burgdorferi IgG and two with anti-TBE. Among them one was co-infected with B. burgdorferi and TBEV. Correlations between anti-C. burnetii IgG and anti-B. burgdorferi IgG presence and between anti-C. burnetii IgG presence and symptoms of Lyme disease were observed. C. burnetii DNA was not detected in any of the 540 (0%) patients. Conclusions C. burnetii is rarely transmitted by ticks, but we proved that it is present in the environment, so it may be a danger to humans. The most common co-occurrence after tick bite concerns C. burnetii and B. burgdorferi.
