Spatial distribution and impact of the gill-parasitic Mazocraes alosae (Monogenea Polyopisthocotylea) on Alosa alosa and A. fallax (Actinopterygii, Clupeidae) [PDF]

, 2016
Are the distribution of Mazocraes alosae and its impact on the host similar between Alosa alosa and A. fallax according to their resemblances? Parasites were numbered on each gill of shads sampled in North-East Atlantic coastal waters and connected ...

Trickle and single infection with Discocotyle sagittata (Monogenea: Polyopisthocotylea): effect of exposure mode on parasite abundance and development [PDF]

Folia Parasitologica, 2002
Experimental infection of rainbow trout Oncorhynchus mykiss (Walbaum) with the monogenean Discocotyle sagittata (Leuckart, 1842) allowed comparison between trickle and single exposure, two infection modes demonstrated to occur in the wild. Both types of infection resulted in mean larval attachment success around 50%, which was significantly dependent ...

ULTRASTRUCTURAL STUDIES ON THE FORM AND FUNCTION OF THE GASTRODERMIS OF PROTOPOLYSTOMA XENOPI (MONOGENOIDEA: POLYOPISTHOCOTYLEA)

The Biological Bulletin, 1973
1. Ultrastructural studies reveal that the cecal epithelium of the monogenean Protopolystoma xenopi is composed of two cell types. Hematin-containing cells are discontinuously arranged and alternate with a thin cytoplasmic layer, the connecting syncytium.2.
