Komodo dragon blood shows promising antimicrobial properties
Komodo dragons eat the decaying flesh of dead animals and live in bacteria-rich environments. 
Scientists create synthetic peptide that helps to heal wounds

A novel way to kill antibiotic-resistant bacteria, inspired by the germ-fighting abilities of Komodo dragons, has been created by scientists in the US.

According to research published in the journal NPJ Biofilms and Microbiomes, the method kills antibiotic resistant bacteria whilst spurring the body’s cells to heal cuts faster.

The work is the result of a $7.57 million government contract to discover new bacterial infection-defeating compounds in the blood of Komodo dragons and crocodiles.

These reptiles eat the decaying flesh of dead animals and live in bacteria-rich environments, suggesting they have strong natural immunity.

“Synthetic germ-fighting peptides are a new approach to potentially defeat bacteria that have grown resistant to conventional antibiotics,” said microbiologist Monique van Hoek from George Mason University, Virginia.

“The antimicrobial peptides we’re tapping into represents millions of years of evolution in protecting immune systems from dangerous infections.”

The research is initially designed to help soldiers heal faster and protect them from biological weapons. Eventually, it could also be available in bandages sold in drug stores to help heal more mundane cuts and scrapes.

In the study, scientists analysed hundreds of peptides in the blood of a single Komodo dragon and discovered one that showed a promising combination of antimicrobial and anti-biofilm properties.

The researchers rearranged the peptide’s amino acids to create a modified, synthetic version. Named “DRAGN-1” in honour of the Komodo dragon, the peptide is the first Komodo-inspired peptide the team created in the lab from this research.

“The synthesised peptide DRGN-1 is not a Komodo dragon’s natural peptide,” Van Hoek said. “it’s been already to be stronger in terms of both potency and stability.”

The peptide is able to attack the sticky biofilm that protects the bacteria and helps them grow in wounds. After breaking down the biofilm barrier, the synthetic peptide kills the bacteria whilst simultaneously stimulating the patient’s cells to heal the wound.

“The next steps for DRGN-1 are to develop it into wound-healing products for veterinary medicine before moving to products designed for humans,” the researchers said.

Vets to run marathon for World Animal Protection

News Story 1
 Two recently graduated veterinary surgeons will be running the London Marathon in April to raise money for the charity World Animal Protection.

Alex Bartlett and Maeve O'Neill plan to run the race together if they are given the same start times.

Dr O'Neill said: "You're always limited in what you can do to help animals, so it is nice to raise money for a charity that helps animals around the world."

Dr Bartlett added: "I have never run a marathon before and am excited to run my first one for such a good cause!"

Both Dr Bartlett and Dr O'Neill have fundraising pages online.

BSAVA releases new Guide to Procedures

The British Small Animal Veterinary Association (BSAVA) has published a new edition of its Guide to Procedures for Small Animal Practice.

It has added four new procedures; cystostomy tube placement, endotracheal intubation, point-of-care ultrasound and wet-to-dry dressings.

BSAVA says that it is an essential step-by-step guide to diagnostic and therapeutic procedures performed in practice. The textbook includes new images and illustrations, as well as high-definition videos for use prior to procedures.

Nick Bexfield and Julia Riggs, editors of the new edition, said: "We have built upon the success of the previous editions by responding to the feedback received from the BSAVA readership, and hope this new guide helps to further increase the confidence and accuracy with which these procedures are performed."

Print copies are available in the BSAVA store, with a digital version in the BSAVA library.
