No Tail No Fail: Life Cycles of the Zoogonidae (Digenea)

open access: yesDiversity, 2023
The Zoogonidae is the only digenean family where known cercariae lack the tail but actively search for the second intermediate host. However, the data on the zoogonid life cycles are scarce. In the present study, we elucidated and verified life cycles of the Zoogonidae from the White Sea.

Characterization of Clinostomum (Digenea: Clinostomidae) spp. in India

open access: yesParasitology Research, 2022
Abstract Platyhelminths belonging to the family Clinostomidae (Digenea) have a worldwide distribution and are known to infect piscivorous birds through their intermediate hosts, usually fish species. In the present study, clinostome metacercariae were collected from fish hosts, including Channa punctata (Bloch 1793) (n = 25) and Trichogaster fasciata ...

UTILIZATION OF EXOGENOUS GLUCOSE BY THE REDIAE OF PARORCHIS ACANTHUS (DIGENEA: PHILOPHTHALMIDAE) AND CRYPTOCOTYLE LINGUA (DIGENEA: HETEROPHYIDAE)

open access: yesThe Biological Bulletin, 1967
1. The rediae of P. acanthus and C. lingua and their gastropod hosts T. lapillus and L. littorea, contained substantial amounts of "free" carbohydrate and polysaccharide. The free fraction consisted of glucose and at least one other sugar probably trehalose.2. Rediae and host heptopancreas tissues absorbed exogenous glucose and incorporated significant
