Abstract

Background

, the most abundant species of jellyfish along the southern coast of Brazil, frequently stings bathers during the summer months, when the occurrence of this species usually reaches a peak.

Objective

As jellyfish are rich in protein and carbohydrates, and as these biomolecules could provide a natural defense against stings, this study investigates whether any of the components present in the umbrella of jellyfish species occurring in the south of Brazil can inhibit the nematocyst discharge of the tentacles of .

Methods

Sting tests were conducted in humans, with live tentacles of , to evaluate different lyophilized extracts of different exumbrellar jellyfish tissues obtained at different times of the year to determine their capacity to reduce pain and alter skin color.

Results

Of all the species of jellyfish used in this study ( and ), only the lyophilized extract of the cubozoa umbrella showed the capacity to inhibit the pain associated with nematocyst stings.

Conclusion

Tests on a lyophilized extract obtained from organisms caught in summer and winter suggested that the biomolecule responsible for the biological activity is carbohydrate since this biomolecule would signal the recognition of the species. Jellyfish are rich in protein and carbohydrates, and as these biomolecules could provide a natural defense against stings. This study investigates whether any of the components present in the umbrella of jellyfish species occurring in the south of Brazil can inhibit the nematocyst discharge. Of all the species of jellyfish used in this study, only the lyophilized extract of the cubozoa umbrella showed the capacity to inhibit the pain associated with nematocyst stings of the It is suggested that the biomolecule responsible for the biological activity is carbohydrates.
