Biological control potential of red-tide marine dinoflagellate blooms by an Amoebophrya parasitic killer.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Despite the widespread prevalence of the genus Karenia, a notorious contributor to harmful algal blooms (HABs) worldwide, there are no reported instances of Amoebophrya spp. infecting Karenia. In 2020, we isolated infected Karenia mikimotoi cells, performed repeated inoculations of these infected cells to uninfected host cultures, and isolated a parasite strain of Amoebophrya from Osaka Bay, Japan. This strain exhibited infectivity toward K. mikimotoi and Karenia papilionacea but not Karenia selliformis or 14 other dinoflagellate species, highlighting its remarkable host specificity. Laboratory coculture experiments revealed pronounced host growth suppression upon introducing the parasite. The prevalence of infection surged rapidly, reaching a peak of 97% at 60 h post addition of the parasite, underscoring its potent infectivity. Our findings suggest that Amoebophrya sp. OSK2020 strain can inhibit K. mikimotoi, making them a promising natural biological control agent for HABs with a minimal impact on marine microbial ecosystems.
