Marine Biotoxins as Potential Nematocide: Impact of Cassiopea andromeda Venom Against Acute and Chronic Trichinellosis in Murine model.
Article in Acta parasitologica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundA significant challenge in the treatment of trichinellosis is addressing theencysted larvae. The efficacy of albendazole on larvae appears to be limited, underscoring theurgent necessity for developing effective alternatives. Recently, marine biotoxins have beeninvestigated as possible substitutes for traditional medications. In the present work, we assessedthe nematocidal potential of the jellyfish Cassiopea andromeda’s venom against the enteral andparenteral phases of Trichinella spiralis in mice.
methodsA total of 115 BALB/c mice werecategorized into two phases: acute and chronic. Each was divided into five groups: uninfecteduntreated group, untreated group infected with T. spiralis , uninfected group and treated withjellyfish venom, infected group and administered albendazole, and infected group and treatedwith jellyfish venom. In vitro study exposed adults and larvae of T. spiralis to the Lethalconcentration (LC90) of C. andromeda venom, and ultrastructural changes were observed. Invivo assay included haematological and biochemical analyses. Histopathological andimmunohistochemical assessments evaluated the host tissue’s alterations. ANOVA and post hoctests were used in the statistical analysis.
resultsThe present results showed that the LC90 ofthe venom caused complete mortality of adults. The infected and venom-treated group of micegained weight, achieved a 85.23% reduction in adult worms, and showed verified structural improvement, diminished degenerative changes, and decreased P53 expression. High levels of oxidative stress indicators and liver enzymes were observed.
conclusionsVenom treatmentdecreased inflammation and restored antioxidant levels. C. andromeda venom may be aninteresting alternative for treating T. spiralis' intestinal and muscle phases; however, furtherresearch is needed to clarify its structure, production, molecular targets, and methods ofadministration.
