Antimicrobial properties found in scorpion venom

Compounds kill staph and drug-resistant TB bacteria - study

Scientists have discovered two healing compounds in scorpion venom that can kill staphylococcus and drug-resistant TB bacteria.

The scorpion, Diplocentrus melici (not pictured), is native to eastern Mexico and can only be found in the rainy season - it is buried during the winter and dry seasons. When researchers milked its venom, they noticed they it changed from clear to brownish in colour when exposed to the air.

Two chemical compounds were found to be responsible for the colour change, one of which turned red when exposed to air, the other blue. The compounds are two previously unknown benzoquinones, a class of ring-like molecules known to have antimicrobial properties.

Through much trial and error, the team - which comprised researchers from Stanford and Mexico - managed to synthesise the compounds. The red benzoquinone was particularly effective at killing staphylococcus bacteria, while the blue one was lethal to both normal and multi-drug-resistant strains of TB-causing bacteria.

Researchers said being able to synthesise the venom is highly important, as the amount of venom components that can be obtained from animals is extremely low.

The team are planning to work together in determining why the compounds are present in the venom and whether they can be transformed into drugs. Their findings have been published in the journal Proceedings of the National Academy of Sciences.

Veterinary Evidence Student Awards winners revealed

News Story 1
 The first winners of the RCVS Knowledge Veterinary Evidence Student Awards have been revealed.

Molly Vasanthakumar scooped first prize for her knowledge summary comparing the ecological impact of woven versus disposable drapes. She found that there is not enough evidence that disposable synthetics reduce the risk of surgical site.

Second prize went to Honoria Brown of the University of Cambridge, for her paper: ‘Can hoof wall temperature and digital pulse pressure be used as sensitive non-invasive diagnostic indicators of acute laminitis onset?’

Edinburgh’s Jacqueline Oi Ping Tong won third prize for critically appraising the evidence for whether a daily probiotic improved clinical outcomes in dogs with idiopathic diarrhoea. The papers have all achieved publication in RCVS Knowledge’s peer-reviewed journal, Veterinary Evidence.

Animal Welfare Foundation seeks new trustees

The Animal Welfare Foundation (AWF) seeks three new trustees to help drive the charity’s mission to improve animal welfare through veterinary science, education and debate.

Veterinary and animal welfare professionals from across the UK may apply, particularly those with experience in equine and small animal practice and research management. Trustees must attend at least two meetings a year, as well as the annual AWF Discussion Forum in London.

For more information about the role, visit www.animalwelfarefoundation.org.uk. Applications close at midnight on 13 August 2019.
