Researchers at Southern Cross University have identified a promising source for new antibiotics: oyster blood. The study reveals that antimicrobial proteins found in the blood of Sydney rock oysters (Saccostrea glomerata) effectively combat specific bacteria responsible for infections.
Notably, these proteins demonstrate strong effects against resistant bacteria such as Streptococcus pneumoniae and Staphylococcus aureus. Tests indicate that proteins derived from oyster blood can enhance the efficacy of existing antibiotics by 2 to 32 times, with no toxic effects on healthy human cells.
Additionally, the proteins not only kill bacteria but also prevent the formation of biofilms, structures that bacteria create for protection, which are known to complicate infection treatment.
This research highlights the potential of oysters as not just seafood but also as a valuable resource for public health. The findings were published in the journal PLOS ONE.
