Fish slime crock of gold at end of rainbow

07.09.2004


The slippery mucus on the skin of rainbow trout is being studied by scientists as a possible source of new medicines to fight infectious diseases, according to research presented Monday, 06 September 2004 at the Society for General Microbiology’s 155th Meeting at Trinity College Dublin.

“Anglers, cooks and anyone cleaning up mess in their kitchen know how difficult it is to hold onto fresh slippery fish like rainbow trout,” says Dr Vyv Salisbury from the University of the West of England in Bristol. “Trout are tricky to grasp because of the thick mucus they secrete from their skin. This slime helps them in many ways, and contains important chemicals which let them fight off bacteria living in the river.”

The scientists are looking at the possibility that the same chemicals might be used to help people fight off infectious disease-causing bacteria including food poisoning culprits E. coli O157and Salmonella, and Pseudomonas aeruginosa which affects the lungs of vulnerable cystic fibrosis patients. To see if the fish slime has an effect, the team at UWE are using genetically modified disease-causing bacteria, which glow in the dark when they are active and stop glowing when they are killed. The drop in the light given off by these bioluminescent reporter bacteria when they are put on the fish slime is a very effective way of seeing how successful the slime action is, but it does mean that the researchers have to spend hours in a totally darkened lab, peering at the fish.



Extracts from the trout mucus have already been shown to prevent growth and slow down the metabolic activity of some of these types of infectious bacteria. “If we can purify and produce these chemicals commercially, they may give us a new type of antibiotic, badly needed with the growing menace of antibiotic-resistant bacteria,” says Dr Salisbury.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
