Table 2 Prevalence of Neorickettsia infection among individual cercariae and sporocysts parasitizing snails, Nelson Co., North Dakota

From: Transmission rates of the bacterial endosymbiont, Neorickettsia risticii, during the asexual reproduction phase of its digenean host, Plagiorchis elegans, within naturally infected lymnaeid snails

Digenean species Life cycle stage % positive (N)
Plagiorchis elegans Cercariae 11% (100)
Plagiorchis elegans Cercariae 52% (100)
Plagiorchis elegans Cercariae 70% (50)
Plagiorchis elegans Cercariae 91% (100)
Plagiorchis elegans Cercariae* 90% (50)
Plagiorchis elegans Sporocysts* 100% (50)
  1. *sporocysts and cercariae obtained from the same snail individual.
