| Popis: | SUMMARYTrichomonas gallinaeis an emerging pathogen in wild birds, linked to recent declines in finch (Fringillidae) populations across Europe. Globally, the main hosts for this parasite are species of Columbidae (doves and pigeons); here we carry out the first investigation into the presence and incidence ofTrichomonasin four species of Columbidae in the UK, through live sampling of wild-caught birds and subsequent PCR. We report the first known UK cases ofTrichomonasinfection in 86% of European Turtle DovesStreptopelia turtursampled, along with 86% of Eurasian Collared DovesStreptopelia decaocto, 47% of WoodpigeonsColumba palumbusand 40% of Stock DovesColumba oenas. Birds were more likely to be infected if the farm provided supplementary food for gamebirds. We found three strains ofT. gallinaeand one strain clustering within theTrichomonas tenaxclade, not previously associated with avian hosts in the UK. OneT. gallinaestrain was identical at the ITS/5.8S/ITS2 ribosomal region to that responsible for the finch trichomonosis epizootic. We highlight the importance of increasing our knowledge of the diversity and ecological implications ofTrichomonasparasites in order further to understand the sub-clinical impacts of parasite infection. |
