Gastrointestinal Parasites of Domestic Ducks (Anas platyrhynchos domesticus) in Kathmandu, Nepal

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Gastrointestinal parasites in ducks raised on smallholder farms in Kathmandu, Nepal, are investigated using copromicroscopic examination. A diverse range of protozoa and helminth parasites are detected including the first records of Entamoeba spp., Cryptosporidium sp. and Tyzzeria sp. in ducks in Nepal.

Paratenic hosts of the swimbladder nematode Anguillicola crassus [PDF]

open access: yes, 1992
The host specificity and population dynamics of Anguillicola crassus in a number of paratenic hosts were investigated. Various freshwater fish species were sampled monthly (March 1990 to March 1991) from the Kolenhaven (Albertcanal, Genk, Belgium) and ...

Life Cycle and Paratenesis of American Gordiids (Nematomorpha: Gordiida) [PDF]

open access: yes, 2004
To complete their life cycle, gordiids must make a transition from aquatic to terrestrial environments. However, epibenthic aquatic larvae and their terrestrial definitive hosts do not overlap in habitat.

Morphological description of infective larval stage of Physaloptera (Spirurida: Physalopteridae), and histological lesions in the paratenic host Leptodactylus macrosternum (Anura: Leptodactylidae) in Caatinga biome, Brazil

open access: yesRevista Mexicana de Biodiversidad, 2022
The present study aimed to describe the infective larval stage of Physaloptera sp. parasitizing Leptodactylus macrosternum and the microscopic lesions of these larvae in the stomach wall. Forty-five specimens of L. macrosternum were collected during the

Host specificity and genetics of host resistance in the "Daphnia-Pasteuria" host-parasite system [PDF]

open access: yes, 2012
Antagonistic coevolution plays an important role in a large number of evolutionary and ecological phenomena. Furthermore, according to the Red Queen Theory coevolution between hosts and their parasites may explain the maintenance of sexual reproduction ...

Metabarcoding of Broad‐Diet Nototheniid Fish Stomachs Reveals Newly Detected Antarctic Parasite Signals and Potential Host Associations

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Using 18S rDNA metabarcoding of stomach contents from two Antarctic nototheniid fishes, we detected 242 parasite OTUs. Protists dominated diversity, metazoans dominated abundance, and depth structured assemblages. Novel parasite–host associations and previously unreported pathogenic protists highlight fish metabarcoding as a tool for biodiversity and ...

Within-Host Dynamics of Multi-Species Infections:Facilitation, Competition and Virulence [PDF]

open access: yes, 2012
Host individuals are often infected with more than one parasite species (parasites defined broadly, to include viruses and bacteria). Yet, research in infection biology is dominated by studies on single-parasite infections.
