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.

Face covering rules expanded

News Story 1
 New rules came into force in England on Saturday (8 August) making it mandatory for clients to wear a face covering in veterinary practices.

The rules, which also apply to cinemas, museums and places of worship, follow a recent spike in coronavirus cases. All clients in England must now wear a face covering when inside a veterinary practice unless they are exempt for age, health or equality reasons.

BSAVA webinars to shine the spotlight on selected journal papers

A free series of webinars that take a closer look at selected papers published in the Journal of Small Animal Practice has been produced by the BSAVA.

In the new BSAVA Science webinar series, authors of the featured papers discuss their results with a panel and how they may impact clinical practice. The authors then answer questions submitted by audience members.

The webinars are available via the BSAVA Webinar Library, covering four different papers. JSAP editor Nicola Di Girolamo, said: "Discussing the research with the authors - experts in their field - really helps to bring the papers to life."
