Mining various genomic resources to resolve old alpha-taxonomy questions: A test of the species hypothesis of the Proteocephalus longicollis species complex (Cestoda: Platyhelminthes) from salmonid fishes

Jan Brabec et al.

Summary: High-throughput sequencing strategies have been commonly used to study non-model parasites, but the corresponding genomes and transcriptomes are seldom explored. In this study, reduced-representation genomic and transcriptomic data were used to investigate the molecular diversity of the cestode Proteocephalus longicollis. Molecular phylogeny revealed high genetic divergence between Proteocephalus isolates from different salmonids, low genetic differentiation within the parasite's populations hosted by the European whitefish, and distinct lineages for Proteocephalus spp. from North American lake whitefish, brown trout, and Arctic charr. These findings advance our understanding of the interrelationships within the Proteocephalus-aggregate and support the resurrection of some nominal species.

Helminths of the Bluntnose Sixgill Shark, Hexanchus griseus (Bonnaterre, 1788), from the Strait of Messina (Sicily, Southern Italy)

Giovanni De Benedetto et al.

Summary: This study describes the parasitic fauna of Hexanchus griseus in the central Mediterranean Sea, identifying three species of helminths. The findings contribute to our understanding of the parasite community of this species.

Could Fish Feeding Behaviour and Size Explain Prevalence Differences of the Nematode Eustrongylides excisus among Species? The Case Study of Lake Garda

Vasco Menconi et al.

Summary: The study investigated the parasitism of Eustrongylides excisus in freshwater fish in Lake Garda, Italy, and found significant differences in prevalence values among different fish species. Piscivorous fish species were more likely to be positive for E. excisus, with the highest prevalence in Micropterus salmoides. Additionally, a negative correlation between body size and E. excisus was observed in Perca fluviatilis, which mainly feeds on zooplankton and benthic invertebrates.
