Breakthrough Discovery: Oyster Protein Offers Hope Against Drug-Resistant Bacteria

AUAustralia|

Australian researchers have made a significant discovery regarding a protein in the blood of the Sydney rock oyster, Saccostrea glomerata, which could prove effective in combating drug-resistant bacteria. The protein, found in the oyster's haemolymph, demonstrates the ability to kill various harmful bacteria and enhance the efficacy of certain antibiotics.

In laboratory tests, the oyster protein effectively eliminated strains of Streptococcus pneumoniae and Streptococcus pyogenes, known to cause pneumonia and strep throat, respectively. Additionally, when combined with antibiotics such as ampicillin and gentamicin, the protein augmented their effectiveness significantly against other serious bacterial infections.

The emergence of antimicrobial resistance has been described as a major global health crisis, prompting researchers to explore innovative solutions. According to Prof. Kirsten Benkendorff from Southern Cross University, approximately two dozen oysters would supply enough haemolymph to provide a therapeutic dose of the protein for an individual, though further studies are needed to fully harness its potential.

While the findings are promising, Benkendorff cautioned against relying on oyster consumption for antibiotic treatment, as cooking deactivates the protein's antimicrobial properties. The protein's ability to disrupt bacterial biofilms offers additional advantages, potentially aiding in treatment approaches for infections resistant to standard antibiotics.

Experts express enthusiasm about this discovery, highlighting its potential to contribute to the fight against escalating drug-resistant infections. The study has been published in the journal Plos One.

Australian Scientists Discover Breakthrough Molecule to Combat Neurodegenerative Diseases

A research team from Australia's Walter and Eliza Hall Institute of Medical Research in Melbourne has identified a small molecule that may help prevent cell death associated with neurodegenerative diseases, including Parkinson's and Alzheimer's. According to findings published in *Science Advances* on May 12, 2025, the molecule targets a protein known as BAX, which is responsible for cell damage and death. Professor Guillaume Lessene, a key researcher in the study, expressed excitement about the discovery, stating, "Turning off BAX alone may be sufficient to limit cell death in neurons." After screening more than 100,000 chemical compounds, the team found that the molecule can inhibit BAX's function, effectively preserving cell viability by preventing mitochondrial damage. This breakthrough addresses a critical gap in the treatment of neurodegenerative conditions, as developing drugs to block cell death has proven difficult. The research suggests potential pathways for creating next-generation therapies that could alter the course of diseases such as Alzheimer's and Parkinson's, offering new hope for patients.

Family Member Charged with Manslaughter in Death of Four-Week-Old Baby

A 26-year-old man was charged with manslaughter concerning the death of a four-week-old baby nearly two years after the infant’s passing, as reported by police in Wagga Wagga, New South Wales. The accused, described as a family member, brought the critically ill child to Wagga Wagga Base Hospital in July 2023, presenting with multiple broken bones and other allegedly inflicted injuries. Tragically, the infant succumbed to his injuries three days later at Sydney Children’s Hospital. Detective Inspector Peter Owen noted that the incident has deeply affected the local community, emphasizing the tragic nature of infant deaths, particularly those involving suspected inflicted injuries. The suspect was granted bail on a $10,000 surety following his court appearance on Friday and is scheduled to return to Wagga Wagga Local Court in July. The investigation into the case involved assistance from the NSW Crime Commission, highlighting the significant effort by local detectives over the past two years. The baby is survived by two siblings, according to police statements.

Mother Accused of Murders Lured Victims with Fake Cancer Diagnosis

Erin Patterson, a 50-year-old mother from Leongatha, Victoria, is on trial for allegedly murdering her estranged husband's parents and aunt by serving them poisonous mushrooms during a lunch she hosted under the guise of discussing her supposed cancer diagnosis. Prosecutors claim that Patterson fabricated the illness to bring her victims together, stating, “The accused said that it was important that the children were not present for the lunch,” according to prosecutor Nanette Rogers. In July 2023, Don and Gail Patterson, both 70, and Heather Wilkinson, 66, fell seriously ill after consuming a meal that included beef Wellington allegedly laced with death cap mushrooms. While Patterson’s guests succumbed to the poison, Reverend Ian Wilkinson survived but required weeks of hospitalization. The trial has drawn significant media attention, and evidence presented includes a food dehydrator traced to Patterson, found with traces of the toxic mushrooms. Patterson’s defense attorney, Colin Mandy, argued that the deaths were accidental and that Patterson did not intend to harm her guests. The trial is expected to continue for several weeks, with expert testimonies and additional evidence to be presented.
