Coprodiagnosis of Echinococcus granulosus infection in dogs from Ankara, Turkey.

The present study were undertaken to compare two isolation techniques (centrifugal flotation and sedimentation) for recovering taeniid eggs from faecal samples, to identify E. granulosus DNA from taeniid eggs by PCR, and to determine the prevalence of E. granulosus in dogs in villages. Faecal samples were collected from 100 dogs in Ankara province. Taenia spp. eggs were found in 27% of dogs faeces. Echinococcus granulosus-specific PCR was obtained in 14 (51.85%) of the taeniid eggs-positive samples. As well as finding Taenia eggs in dogs' faeces, we also found eggs of some helminthic parasites; such as Dipylidium caninum, Toxocara canis, Toxascaris leonina, Trichuris sp., Capillaria sp., Filaroides sp., Dioctophyme renale, Linguatula serrata, hookworm, Dicrocoelium sp., Fasciola sp. and Ascaridia galli. Significantly, more dogs excreting taeniid eggs were diagnosed with the sedimentation method (n=27) as compared to the flotation method (n=10).
