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: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
