Oyster Blood Shows Potential in Combating Antibiotic-Resistant Superbugs

Research reveals proteins in Sydney rock oyster blood can kill bacteria and enhance antibiotic efficacy without toxicity to human cells.

Scientists from Southern Cross University have identified antimicrobial proteins in the hemolymph of Sydney rock oysters that kill bacteria and improve the effectiveness of existing antibiotics.
The proteins disrupt bacterial biofilms, protective layers that shield bacteria from antibiotics and the immune system, making infections more treatable.
The study demonstrated up to a 32-fold increase in the efficacy of antibiotics like ampicillin and gentamicin against bacteria such as Streptococcus pneumoniae and Staphylococcus aureus.
Tests confirmed the proteins are non-toxic to human lung cells, paving the way for potential future development into antimicrobial therapies.
While promising, further research, including animal and human trials, is necessary before these proteins can be developed into clinical treatments.
