ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Marine Parasite Biogeography Mirrors Host Patterns Across Latitude, Area, and Diversity

New Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Parasites are integral components of biodiversity, yet they remain poorly represented in large‐scale biogeographic theory. In this study, we test whether marine parasites follow three macroecological patterns established for free‐living taxa, namely that parasite species richness: (1) scales positively with area (both host body size and geographic area)

Lost and Found: Piwi and Argonaute Pathways in Flatworms

Frontiers in Cellular and Infection Microbiology, 2021
Platyhelminthes comprise one of the major phyla of invertebrate animals, inhabiting a wide range of ecosystems, and one of the most successful in adapting to parasitic life.

Contribution to the knowledge of the family Otoplanidae Hallez, 1892 (Rhabditophora, Proseriata) in the Mediterranean [PDF]

, 2009
A growing awareness is rising that present perception of marine biodiversity is inadequate, and based upon unrepresentative data. The inadequacy of knowledge on taxonomy and distribution of marine organisms is particularly acute for interstitial ...

Use of freeze-cracking in ontogenetic research in Macrostomum lignano (Macrostomida, Rhabditophora) [PDF]

, 2009
A method for studying whole mount flatworm embryos based on freeze-cracking of the eggs is described. This method allows successful immunohistological and immunocytological studies of whole mount embryos.

Platyhelminths as paleogeographical indicators [PDF]

Hydrobiologia, 1995
Turbellarians do not feature as examples in the present discussions on the theory and method of analytical biogeography. It is argued, however, that turbellarian distributional records form good examples of large-scale biogeographic patterns resulting from continental breakup.

Zoonotic risks in urban areas: Prevalence of helminth parasites in urban populations of Lissachatina fulica in Sarawak, Malaysia

Veterinary Record Open, Volume 13, Issue 1, June 2026.
Abstract Background The giant African land snail (Lissachatina fulica), an invasive species with significant medical, agricultural and economic importance, is abundant in urban areas of Kota Samarahan, Sarawak. The proximity between humans and the snail may increase the risk of pathogen transmission.

Two new species of Plagiostomum (Prolecithophora, Plagiostomidae) from China with its morphology, phylogeny, and reproductive strategy

Frontiers in Marine Science
Plagiostomum flatworms are small, free-living organisms frequently found in saltwater or freshwater habitats, but their biological characteristics remain largely unknown.

Helminths and Cancers From the Evolutionary Perspective

Frontiers in Medicine, 2018
Helminths include free-living and parasitic Platyhelminthes and Nematoda which infect millions of people worldwide. Some Platyhelminthes species of blood flukes (Schistosoma haematobium, Schistosoma japonicum, and Schistosoma mansoni) and liver flukes ...

Girardia festae (Borelli, 1898) (Platyhelminthes: Tricladida: Dugesiidae): distribution extension in a high-altitude lake from Colombia [PDF]

Check List, 2012
We revise the Neotropical distribution of Girardia festae (Platyhelminthes, Dugesiidae) following a new record in a Colombian high-altitude lake. G. festae is a freshwater planarian known mainly in the Andean Cordillera from Venezuela to Argentina.
