Tetrahymenid ciliates as parasites of the gray garden slug

Wayne M. Brooks

Hilgardia, 1968, vol. 39, issue 8

Abstract: The role of two species of holotrichous ciliates, Tetrahymena limacis and T. rostrata, as parasites of the gray garden slug, Deroceras reticulatum, was examined. Infectivity tests with each ciliate species demonstrated that T. rostrata was pathogenic for D. reticulatum, producing subacute, lethal infections. Infection with T. limacis was not fatal. The only noticeable effect was a significant difference in the size and weight of the newly hatched slugs that had been exposed to a heavy concentration of ciliates.
