A research effort led by Ōtākou Whakaihu Waka has generated an in-depth structural map of a bacteriophage, offering new insight into how these viruses could be used to counter drug-resistant bacteria.
Published research builds on earlier work and highlights the ancient origins of these viruses.
Unlocking the Secrets of Bacteriophages
Scientists at Ōtākou whakaihu Waka have created a detailed structural map of a bacteriophage – a virus that infects bacteria. This breakthrough, detailed in recent research, provides crucial insights into the evolution of these viruses and their potential as alternatives to conventional antibiotics in the face of growing antimicrobial resistance. The research was led by Dr. James Hodgkinson-Bean, who completed his PhD in the Department of Microbiology and Immunology.
Dr. Hodgkinson-Bean describes bacteriophages as “extremely exciting” for scientists seeking alternatives to antibiotics. Antimicrobial resistance is a critical global health threat, prompting the search for novel therapeutic strategies.
The team’s work demonstrates that the three-dimensional structure of a virus can be more informative about its distant evolutionary relationships than DNA alone. While DNA is a useful marker for recent evolution, viral structure reveals connections stretching back billions of years.
“While DNA generally serves as the best evolutionary marker in humans, the 3-dimensional structure of a virus is more informative of its distant evolutionary relationships with other viruses,” Dr. Hodgkinson-Bean explains.
The research identified previously unseen features linking this bacteriophage to distantly related viruses, uncovering previously undocumented evolutionary connections. Specifically, the study highlights the relationship between bacteriophages and herpes viruses, a connection thought to predate the emergence of multicellular life.
“We certainly know through structural studies that bacteriophages are related to Herpes viruses — this relationship is thought to extend back billions of years to before the emergence of multi-cellular life. For this reason, when we look at bacteriophage structure, we are looking at living fossils, primordial ancient beings,” Dr. Hodgkinson-Bean stated. “There is something truly beautiful about that.”
Building on Previous Research
This latest structural description is the second from the same research group. Their earlier work, published in Nature Communications, focused on pathogens responsible for potato diseases. This demonstrates a continued commitment to understanding viral structures and their implications.
Implications for Combating Antibiotic Resistance
Bacteriophages offer a promising avenue for combating antibiotic resistance. Unlike antibiotics, which kill bacteria indiscriminately, bacteriophages specifically target and destroy bacterial cells. This targeted approach minimizes disruption to the gut microbiome and reduces the selective pressure that drives antibiotic resistance.
Further research is needed to fully explore the therapeutic potential of bacteriophages, including optimizing delivery methods and addressing potential challenges such as bacterial resistance to phages. However, the detailed structural map created by Ōtākou Whakaihu Waka provides a crucial foundation for these future investigations.
