The mode of action of pyrogallol in inducing beneficial effects was tested on Artemia.

Pyrogallol induced protective effects in Artemia against pathogenic Virbio harveyi.

The Vibrio-protective effect was mediated by the prooxidant action of the compound.

The prooxidant effect contributed to the generation of protective immune responses.

The ability of pyrogallol to boost immunity makes it a potential protective agent.
