Oyster blood proteins show promise in fighting antibiotic-resistant bacteria

Researchers have found that proteins from oyster blood may help combat antibiotic-resistant bacteria. A study published in PLOS ONE shows these proteins can kill certain harmful bacteria and enhance the effectiveness of existing antibiotics. Oyster hemolymph, which contains antimicrobial proteins, was tested against various bacterial pathogens. The proteins significantly improved antibiotic effectiveness, particularly against Streptococcus and Staphylococcus species, without harming healthy human cells. Further research is needed, including animal and human trials, to explore the potential of these proteins as new antimicrobial therapies. The availability of Sydney rock oysters may support sustainable research and development efforts.
