Аннотация
Over 40 tick species are naturally infected by Coxiella burnetii. However, little is known about the presence of C. burnetii in other ectoparasites such as fleas. During a 6-year (2000-2006) study, 1147 fleas were collected from 652 animals (252 rats, 118 foxes, and 282 hares) captured from different areas of Cyprus. Three flea species-Xenopsylla cheopis, Ctenocephalides felis, and C. canis-were identified. Fleas were pooled (153 pools) and tested by PCR for the presence of C. burnetii. The pathogen was identified in 25 (16.3%) pools. None of the fleas parasitizing hares was positive for C. burnetii, as opposed to fleas collected from rats (12% pool positivity) and foxes (47.6% pool positivity). The highest prevalence of positive pools was recorded in C. canis (38%) compared to C. felis (16.6%) and X. cheopis (10.8%). All pools of C. canis positive for C. burnetii were removed from foxes (44.4%), whereas all positive X. cheopis (10.8%) were removed from rats. The role of fleas in the maintenance and transmission of C. burnetii among wild vertebrates remains to be determined.
