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.

Gucci pledges to go fur-free

News Story 1
 Italian fashion house Gucci has announced that it will no longer use animal fur in its designs. Gucci’s president & CEO Marco Bizzarri made the announcement on Wednesday (October 11) at The London College of Fashion.

The move follows a long-standing relationship with The Humane Society of the United States and LAV - members of the international Fur Free alliance. Gucci’s fur-free policy includes mink, coyote, raccoon dog, fox, rabbit, karakul and all other species bred or caught for fur.

Avian flu text alert service launched in Northern Ireland

A new text system to alert bird keepers to the threat of avian flu has been launched in Northern Ireland. The service will enable bird keepers to take action to protect their flock at the earliest opportunity.

Keepers who have already provided NI's Department of Agriculture with a valid mobile number have automatically been subscribed to the service and notified by text. Bird keepers who have not yet received a text should text ‘BIRDS’ to 67300 to register.
