Researchers discover new antibiotic in African ant

Tests show antibiotic is highly-effective against MRSA

Researchers have discovered a new species of antibiotic, produced by the bacteria of an African ant, that is highly effective against MRSA.

The finding, published in the journal Chemical Science, was made by scientists at the University of East Anglia and the John Innes Centre.

The new species is a member of the Streptomycin bacteria family and was discovered on the African fungus-growing plant-ant, Tertraponera penzigi.

Tests show that the antibiotic is potent against antibiotic-resistant 'superbugs' such as methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-Resistant Enterococci (VRE).

Professor Wilkinson from the John Innes Centre commented: “Our finding highlights the importance of searching as-yet under-expired environments, which, when combined with recent advances in genome sequencing and editing, enables the discovery of new species making natural product antibiotics which could prove invaluable in the fight against AMR.”

Currently, nearly all of the antibiotics in use originate from a group of bacteria called actinomycetes. This bacteria was isolated from soil between 40 and 80 years ago, in what is known as the ‘golden age’ of antibiotic discovery.

Since then, inappropriate use of these antibiotics has led to widespread antimicrobial resistance where disease-causing bacteria have become resistant to some of these antibiotics.

“We have been exploring the chemical ecology of protective symbioses formed between antibiotic-producing bacteria and fungus-growing insects to better understand how these associations are formed and explore them as a new source of anti-infective drugs,” said Prof Matt Hutchings from the University of East Anglia.

“Kenyan plant-ants live in symbiosis with thorny acacia trees. They live and breed in domatia - which are hollowed out structures which the plant evolved to house them - and grow fungus in them for food. In return, they protect the plants from large herbivores including elephants, which won't eat plants covered in ants.”

The antibiotic has been named ‘streptomyces formicae,’ and the antibiotics formicamycins, after the latin formica, meaning ant.

Nominations for 2019 RSPCA Honours Awards now open

News Story 1
 People across the UK are being urged to nominate a standout animal champion for the 2019 RSPCA Honours Awards.

The awards recognise those who have worked tirelessly to improve animal welfare, campaigned on behalf of animals, or shown true bravery. Previous winners include comedian John Bishop, who was awarded Celebrity Animal Champion of the Year, and 11-year-old Lobby Cantwell, who raised more than £1,000 for the charity through mountain climbs and bike rides.

To submit a nomination or find out more about the awards visit the RSPCA website. Nominations will remain open until 4 pm on Friday, March 15.

New £1m project to investigate dairy cow lameness

Scotland’s Rural College (SRUC) is leading a new £1 million research project to investigate the causes of lameness in dairy cows.

One in three dairy cows are affected by lameness every day in the UK, costing the industry an estimated £250 milion annually.

The project will take three years to complete and is due to finish by November 2021.

Professor Georgios Banos of SRUC commented: “In addition to pain and discomfort to the animal, lameness is associated with decreased milk production and inflated farm costs.

“Among cows raised in the same environment, some become lame while others do not. Understanding the reasons behind this will help us develop targeted preventive practices contributing to enhanced animal welfare and farm profitability.”
