Salmonella in Garden Birds Responsive to Antibiotics

03.06.2008
Scientists at the University of Liverpool have found that Salmonella bacteria found in garden birds are sensitive to antibiotics, suggesting that the infection is unlike the bacteria found in livestock and humans.

Salmonella is increasingly resistant to antibiotics and can sometimes go undetected in animals, which increases the risk of the infection being spread to humans. The team tested the strains found in birds in the laboratory and found that antibiotics were able to kill off the bacteria.

Scientists believed that wild birds carried a variety of Salmonella strains and passed the infection on to livestock through their faeces. Scientists at Liverpool, however, have found that only two Salmonella strains are common in garden birds, neither of which is prevalent in livestock or humans.

Research showed that these strains were a fairly distinct population of bacteria and well adapted in garden birds. They were particularly common in finches - such as greenfinch, siskins and goldfinches - as well as house sparrows.

Dr Paul Wigley, from the National Centre for Zoonosis at the University of Liverpool, said: “Salmonella is a bacterium that causes intestinal infection in humans and can cause illness such as vomiting and diarrhoea - usually through contaminated food like meat or eggs. Symptoms in birds include weight loss, feather ruffling and lethargy. We have witnessed a number of deaths due to Salmonella infection in garden birds and so it was important that we investigated how the disease was being spread.

“We thought that wild birds were incubators for Salmonella but have now found that garden birds carry two strains of a group of Salmonella microorganisms, called Salmonella Typhimurium, itself only one of over 2,500 types of Salmonella. We screened Salmonella genes we knew to be involved in causing disease and found that they lacked a gene normally found in the human form of the infection.

“The work suggests that the infection will keep circulating in the same species, increasing the risk of further disease outbreaks. We now know that these Salmonella strains are not resistant to antibiotics but it would be inadvisable to use antibiotics in garden birds as this would inevitably lead to the development of antibiotic resistant bacteria within these populations. We also now need to explore other possible sources to understand the infection in livestock and humans.”

The research, conducted as part of the Garden Bird Health Initiative led by the Institute of Zoology and in conjunction with the Health Protection Agency, is published in BMC Veterinary Research.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
