Antibacterial activity in egg samples from small‐spotted catshark Scyliorhinus canicula and nursehound Scyliorhinus stellaris : A preliminary investigation

Abstract

The study aims to identify antibacterial properties in unfertilized eggs of Scyliorhinus canicula and Scyliorhinus stellaris . Despite challenging marine conditions, these eggs retain their integrity for extended periods and remain unaffected by pathogens. The antibacterial activity was measured using minimum inhibitory and minimum bactericidal concentration analysis. The eggs of S. stellaris exhibited a slight inhibitory effect against Staphylococcus aureus and Listeria monocytogenes , whereas both species' eggs showed no activity against gram‐negative microorganisms.
