Serious disease in pet lizards caused by new bacteria

22.09.2008
Skin infections are common in pet lizards and can lead to fatal organ disease and septicaemia.

Infections are particularly risky in lizards that are bred in captivity for release into the wild, as they can spread into the wild population. The cause of these diseases has been unclear but now researchers in Belgium have discovered a new bacterium responsible for dermatitis in desert lizards.

According to research published in the September issue of the International Journal of Systematic and Evolutionary Microbiology, the discovery could help control the disease and protect endangered species.

Desert-dwelling lizards belonging to the genera Agama and Uromastyx that live in the arid and desert areas of North Africa are now bred in captivity in Europe. "The establishment of healthy captive populations is an important tool for the conservation of threatened species," said Professor An Martel from Ghent University, Belgium. "On the other hand, restocking of wild populations with captive bred animals carrying pathogens might compromise the survival of these wild populations. Skin diseases are highly prevalent in captive lizards."

Dermatitis is the most important known bacterial disease of desert lizards that prevents successful captive populations from being established. One example is the captive breeding programme of the rare Oman dab lizard (Uromastyx thomasi) a joint project between Germany and Oman, to which pathogens like this may pose a real threat.

"We isolated bacteria from five different desert lizards suffering from dermatitis, two agama lizards (Agama impalearis) and three spiny-tailed lizards (Uromastyx geyri and U. acanthinura)," said Professor Martel. "We could not identify the bacterium that was causing the disease, but the pathogen was the same in all five lizards."

The researchers looked at the genetic sequence of the bacterium and discovered it represents a new taxon and species. They have named the bacterium Devriesea agamarum (Devriesea referring to the veterinary microbiologist L.A. Devriese and agamarum after Agama, an Old World reptile). "We have demonstrated a causal relationship between this bacterium and skin lesions in desert-dwelling lizards," said Professor Martel. "This microbe is also related to bacteria that cause skin infections in humans."

The cases of dermatitis and septicaemia from which the new bacterium Devriesea agamarum was isolated are highly prevalent, especially in captive lizards. The researchers hope the identification of this species will contribute to our understanding of lizard skin disease and help develop control measures. "In the future we would like to study host-pathogen interactions, design treatments and investigate the use of a vaccination to prevent the development of disease caused by Devriesea agamarum," said Professor Martel.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
