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.

Regional Representatives nominations sought

News Story 1
 Seven new regional representatives are being sought by the British Veterinary Association (BVA) to speak for vets from those regions and to represent their views to BVA Council.

The opportunities are available in in the North-East, Yorkshire & Humber, East Midlands, West Midlands, London, Wales, and Northern Ireland. Representatives from all sectors of the veterinary profession are urged to apply.

BVA president Daniella Dos Santos, said: "Our regional representatives are integral to that mission and to the activities of Council - contributing to effective horizon scanning on matters of veterinary policy and providing an informed steer to BVA’s Policy Committee.”

Livestock Antibody Hub receives funding boost

The Pirbright Institute has received US $5.5 million from the Bill and Melinda Gates Foundation to form a Livestock Antibody Hub aimed at supporting animal and human health. The work will bring together researchers from across the UK utilise research outcomes in livestock disease and immunology.

Dr Doug Brown, chief executive of the British Society for Immunology, commented: “The UK is a world leader in veterinary immunology research, and this transformative investment from the Bill & Melinda Gates Foundation will drive the next chapter of innovation in developing new treatments and prevention options against livestock diseases".
