title: [Repeated finding of the North American ciliate Ambiphrya ameiuri (Peritricha: Scyphidae) in the Rybinsk reservoir].
abstract: The first case of a mass infection of fish fry with the ciliate Ambiphrya ameiuri (Thompson e. a., 1946) was found during the summer of 1989 in one of spawning zones of the Rybinsk reservoir. In June-July of 2000 after the ten-year interval, the second case of infection with this parasite in the first-year roach Rutilus rutilus has been observed. The prevalence of A. ameiuri was very low. Nine other species of ciliates forming the ectoparasite community were also observed. Parasites were disposed mostly on a surface fish bodies, gills and more densely on fins.
