4.2 | Diplostomum spp. : Implications for animal health

Several Diplostomidae View in CoL are recorded on Phoxinus View in CoL minnows: Diplostomum commutatum (Diesing, 1850) View in CoL and Hysteromorpha triloba (Rudolphi, 1819) View in CoL were found on P. septimaniae View in CoL in Spain, and Posthodiplostomum cuticola View in CoL and Tylodelphys clavata (von Nordmann, 1832) View in CoL were found on P. phoxinus View in CoL in the UK and P. septimaniae View in CoL in Spain ( Cruz et al., 2022; Hockley, 1935; Kennedy, 1974; Nicoll, 1924). One of the most widespread parasites of Phoxinus View in CoL minnows, D. phoxini (reported under this name and synonyms in the literature, Table 1), a Diplostomidae View in CoL ( Platyhelminthes View in CoL : Digenea), whose metacercariae parasitize the brain of Phoxinus View in CoL minnows, is reported from P. phoxinus View in CoL in Ireland and the UK, Phoxinus sp. 7 in Finland, Norway, the UK, and Russia, P. csikii View in CoL in Switzerland, and P. septimaniae View in CoL in Spain ( Ballabeni, 1994; Cruz et al., 2022; Kekäläinen, Lai, et al., 2014; Kortet et al., 2015; Kristoffersen & Teigland, 1997; Lebedeva et al., 2021; Rees, 1955; Schwelm et al., 2021). However, Lebedeva et al. (2021) showed that Fennoscandian and Mongolian Phoxinus View in CoL minnows were hosts to different Diplostomum species, with a correlation of each line of brain Diplostomidae View in CoL with a specific Phoxinus View in CoL lineage, thus supporting the conclusion of a high specificity of brain Diplostomum View in CoL toward their host. This conclusion is in agreement with the cross-infection experiment conducted by Ballabeni and Ward (1993), which showed that D. phoxini originating from two close Swiss lakes were more infective to their sympatric hosts than to allopatric hosts. Moreover, analysis conducted in North America revealed a wide and previously undetected diversity of Diplostomoidea using barcoding and showed that parasites of this group occurring outside of the eyes are highly host specific ( Locke et al., 2010). These elements suggest cryptic diversity among the brain flukes reported as D. phoxini with potentially several host-specific species parasitizing the numerous Phoxinus species. Gathering data about this parasite may be of veterinary importance as it caused fatal enteritis in chicks of the vulnerable Fratercula arctica (Linnaeus, 1758) View in CoL kept in captivity ( Hoby et al., 2022). Moreover, members of the genus Diplostomum View in CoL are pathogenic to their intermediate fish host. D. phoxini disrupts brain tissue integrity and necrosis of the layer surrounding the larvae (Dezfuli, Capuano, et al., 2007).
