New records of invasive hammerhead flatworms (Platyhelminthes, Geoplanidae, Bipaliinae) from Mexico using a citizen science platform, with an identification key to the species found in North America [PDF]

open access: yesCheck List, 2022
We present new records of the invasive hammerhead flatworms Bipalium kewense Moseley, 1878 and Bipalium vagum Jones & Sterrer, 2005 (Platyhelminthes, Geoplanidae, Bipaliinae) from several states in Mexico based on iNaturalist and two vouchered ...

The Life Cycle of the Acropora Coral-Eating Flatworm (AEFW), Prosthiostomum acroporae; The Influence of Temperature and Management Guidelines

open access: yesFrontiers in Marine Science, 2019
As coral aquaculture is increasing around the world for reef restoration and trade, mitigating the impact of coral predators, pathogens and parasites is necessary for optimal growth.

Characterization of Schistosome Sox Genes and Identification of a Flatworm Class of Sox Regulators

open access: yesPathogens, 2023
Schistosome helminths infect over 200 million people across 78 countries and are responsible for nearly 300,000 deaths annually. However, our understanding of basic genetic pathways crucial for schistosome development is limited.

Fossil constraints on the origin and evolution of Platyhelminthes are surprisingly concordant with modern molecular phylogenies [PDF]

open access: yesZoologia (Curitiba)
Trace fossils preserved with fossil worm-shaped remains suggest the presence of free-living flatworms during the Ordovician at the latest and their occurrence in terrestrial environments during the Permian.

Systematic revision of the family Pleioplanidae Faubel, 1983 (Polycladida, Acotylea): new genus and combinations

open access: yesEuropean Journal of Taxonomy, 2017
New morphological information, reconsiderations and the first combination of a generic name based on a previously established species are presented in the current revision of the family Pleioplanidae (Polycladida, Acotylea).

Fractionation of a sex-inducing substance from flatworms using open-column chromatography and reverse-phase high-performance liquid chromatography

open access: yesSTAR Protocols, 2023
Summary: A substance that sexualizes planarians, an ancestral group of parasitic flatworms, is widely present in planarians and parasitic flatworms. Here, we present a protocol for extracting and purifying the active fraction with sex-inducing activity ...

Transcriptional signatures of somatic neoblasts and germline cells in Macrostomum lignano

open access: yeseLife, 2016
The regeneration-capable flatworm Macrostomum lignano is a powerful model organism to study the biology of stem cells in vivo. As a flatworm amenable to transgenesis, it complements the historically used planarian flatworm models, such as Schmidtea ...

A SIMPLE TECHNIQUE FOR STAINING OF PLATYHELMINTHS WITH THE LACTOPHNOL COTTON BLUE STAIN [PDF]

open access: yesJournal of the Egyptian Society of Parasitology, 2013
This paper describes a simple technique for staining of flatworms using lactophenol cotton blue (LPCB). The staining was tested on 2 trematode species: Heterophyes heterophyes and Mesostephanus appendiculatus, and one cestode: Diplopylidium acanthotetra,

Atp8 is in the ground pattern of flatworm mitochondrial genomes

open access: yesBMC Genomics, 2017
Background To date, mitochondrial genomes of more than one hundred flatworms (Platyhelminthes) have been sequenced. They show a high degree of similarity and a strong taxonomic bias towards parasitic lineages.

Variable host responses mediate host preference in marine flatworm-snail symbioses.

open access: yesPLoS ONE, 2021
Host preference of symbionts evolves from fitness trade-offs. However, it is often unclear how interspecific variations in host response traits influence this evolutionary process.
