New Genomic Toolkit Offers Hope Against Superbugs

Amid rising concerns over antibiotic-resistant infections, an international team of microbial experts has introduced a powerful and versatile online genomic toolkit designed to accelerate the development of phage therapy.

After decades of research, bacteriophages, or phages—viruses that specifically target and destroy bacteria—are emerging as a promising solution to combat the growing threat of antibiotic-resistant "superbugs."

Researchers at Flinders University have unveiled a new platform called Sphae, which can determine whether a phage is suitable for targeted therapy in less than 10 minutes. This represents a significant advancement in the rapid evaluation of phage safety and effectiveness, as highlighted by the Flinders Accelerator for Microbiome Exploration (FAME) team and their collaborators in a study recently published in Bioinformatics Advances.

Sphae integrates high-throughput sequencing technologies with advanced computational pipelines, allowing researchers to analyze vast and complex datasets efficiently. The platform prioritizes safety, flagging genes associated with toxins or undesirable traits to ensure only the safest candidates are selected for therapeutic use.

"Adaptability and scalability set Sphae apart," says Bhavya Papudeshi, the study’s corresponding author and a member of the FAME research group. "The workflow supports a wide range of sequencing technologies, and the toolkit is designed to handle massive datasets typical of high-performance computing environments, making it an invaluable resource for labs tackling large-scale projects."

Beyond its applications in therapeutic research, Sphae also enhances the broader understanding of microbial ecosystems and their impact on global health and climate, notes FAME group Co-Director Professor Robert Edwards from Flinders University’s College of Science and Engineering.

"Sphae processes multiple phage genomes simultaneously, saving time and efficiently handling large datasets. It performs effectively even in mixed or challenging datasets, providing consistent and accurate results to help identify phages capable of combating resistant bacterial strains. The platform offers a comprehensive view of phage genomes, summarizing key features such as resistance and virulence markers for better insight into phage safety and functionality," says Edwards.

The rising prevalence of antibiotic-resistant infections has prompted warnings from both the United Nations and the World Health Organization, particularly regarding their impact on older adults and vulnerable populations. A recent global study published in The Lancet predicts that deaths from antibiotic resistance could more than double to 2 million annually, with the cumulative death toll exceeding 39 million by 2050 unless urgent action is taken to develop alternatives. Another 2022 study estimated that nearly 5 million deaths per year are linked to drug-resistant bacteria, disproportionately affecting low- and middle-income countries.

Professor Edwards emphasizes that global initiatives, such as efforts to establish phage banks for common pathogens like Achromobacter, Acinetobacter, and Stenotrophomonas, are crucial to expanding research into alternative antibacterial treatments.

"When conventional antibiotics fail, personalized phage therapy could become a standard medical approach by streamlining and accelerating the discovery of therapeutic phages suited to individual infections. With initiatives like Phage Australia and innovations such as Sphae, researchers are moving closer to unlocking the full potential of these microbial marvels," Edwards explains.

"The future of medicine lies in the precise, efficient, and safe use of phages to combat bacterial infections and restore hope to patients worldwide."
