18S rRNA gene metabarcoding for investigation of gastrointestinal parasite diversity in great cormorants.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The great cormorant (Phalacrocorax carbo) is a migratory, fish-eating bird that may act as a carrier for various pathogens, raising potential ecological and public health concerns. This study investigated the diversity of gastrointestinal parasites in great cormorants from the Republic of Korea using 18S rRNA gene metabarcoding and conventional diagnostic methods. Fecal samples were collected from 10 great cormorants in Korea, and DNA was extracted for metabarcoding targeting the V4 and V9 regions of the 18S rRNA gene using the MiSeq platform. Conventional PCR and microscopic examination were used for validation. The V4 region of the 18S rRNA gene revealed the presence of Baruscapillaria spiculata, Contracaecum sp., and Isospora lugensae. The V9 region analysis identified the following parasites: Tetratrichomonas sp., Histomonas meleagridis, Trichomitus sp., Tetratrichomonas prowazekii, B. obsignata, Monosiga ovata, and Fasciola gigantica. Furthermore, conventional PCR confirmed the presence of Contracaecum sp., Isospora sp., and unspecified trichomonads, and microscopic examination identified eggs of capillarid, Contracaecum, and Eustrongylides and trophozoites of flagellated protozoa in the collected cormorant fecal samples. The findings underscored the potential ecological role of great cormorants as hosts for diverse gastrointestinal parasites and the utility of 18S rRNA gene metabarcoding for screening the diversity of gastrointestinal parasites in great cormorants.
