On the hunt for deadly frog disease

04.04.2005


CSIRO is working on new methods of detecting a frog fungus which has killed frogs in the United States, Panama, Ecuador, Venezuela, Spain, Australia and New Zealand.



A workshop on new methods of detecting and controlling the spread of one of the world’s most deadly frog diseases – chytridiomycosis – will be held from 4-7 April at CSIRO Livestock Industries’ Australian Animal Health Laboratory (AAHL) in Geelong, Victoria.
CSIRO Livestock Industries’ Dr Alex Hyatt says the disease, caused by the chytrid fungus, has been associated with frog declines in eastern Australia, New Zealand, the United States, Panama, Ecuador, Venezuela and Spain.

"At least one Australian frog species has been wiped out by the chytrid fungus and it is thought that the fungus was a major contributing factor in the extinction of at least another seven species world-wide," Dr Hyatt says.



"In response to this major threat, AAHL has developed diagnostic assays and sampling techniques that enable the rapid detection of the fungus.

"We’ve developed immunohistochemical, molecular and electron microscopy tests for the fungus, along with a range of sampling assays. Using wash water or swabs, tadpoles and frogs can be tested for infection, with the sampling assays detecting even low levels of fungus zoospores," Dr Hyatt says.

Many of the workshop sessions will be held within the microbiologically secure section of AAHL, where biosecurity is stringent. Not only must the participants take a compulsory shower before leaving the high-biocontainment facility, but they will not be allowed to be in contact with livestock and amphibians for seven days after completing the workshop.

Dr Hyatt says an important reason for holding the workshop is to attempt to standardise the diagnostic procedures used throughout the world.

"If labs world-wide are using standardised assays in the same way then we can realistically compare data and work together to develop effective management programs.

"The challenge is to determine where the fungus is in the environment and which species are susceptible. Once we know that, we can implement procedures to protect animals and the environment," Dr Hyatt says.

The workshop’s presenters include: Dr Joyce Longcore from the University of Maine, Associate Professor Rick Speare and Dr Lee Berger from James Cook University and Dr Hyatt.

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...
