Morphological and molecular features of Cosmocerca species (Nematoda: Cosmocercidae) parasitizing Fejervarya kawamurai (Anura: Dicroglossidae) in Japan

Key Points

• The study reveals distinct morphological and molecular features of Cosmocerca species in Fejervarya kawamurai, suggesting unique adaptations.
• Key evidence includes specific molecular markers that differentiate these nematodes, impacting host-parasite interactions.
• Observational analysis identified the relationship between host behavior and the prevalence of parasitic infections among local amphibian populations.
• This work highlights ecological roles of nematode parasites, necessitating further exploration in diverse environments.
