New records of the ectoparasitic flagellate Colpodella gonderi on non-Colpoda ciliates.

Colpodella gonderi is the only ectoparasitic flagellate of ciliated protozoa described thus far. This investigation reveals new records of C. gonderi retrieved from soil samples in southern Scotland, UK. Of fourteen ciliates species identified in one single occasion, three of them, Colpoda steinii, Pseudoplatyophrya nana and Grossglockneria acuta, were infested with the parasite. These results provide further evidence that C. gonderi is not host-specific of the ciliate genus Colpoda.
