The aims of the present study were (a) to determine the presence of Ixodes ricinusin three different areas of the National Park of Abruzzo; (b) to search for the presence of Borrelia burgdorferiin the collected sample of Ixodes; (c) to determine the seroprevalence of B. burgdorferiantibodies and E. chaffeensisantibodies in inhabitants of the park and in park workers. The presence of B. burgdorferiin Ixodeswas checked by PCR. For the detection of antibodies to B. burgdorferiall sera were assayed by ELISA as screening test and by Western blot as confirmatory test. For the detection of antibodies to E. chaffeensisall sera were assayed by IFA. Antibodies to B. burgdorferiwere present in 9.1% of the park workers, 4.5% were confirmed positive by the IgG Western blot test. None of the inhabitants of the park was positive. Antibodies against E. chaffeensiswere found in 4.5% of the park workers and 8% of the inhabitants of the park. The results obtained in the collecting of the ticks seem to show that the presence of I. ricinusin the park territory is rather discontinuous and small in number, therefore it is not epidemiologically significant for the transmission of B. burgdorferisensu lato. Serological study for Ehrlichiarevealed a high frequency of E. chaffeensisantibodies in the park inhabitants and a lower prevalence in the park workers. |
