Superbugs could be untreatable, experts warn 11 April 2008 By Carolyn Tucker Antibiotic resistant infections are becoming increasingly common with experts fearing some could become untreatable unless new antibiotics are developed. That was the grim prognosis presented to The Australasian Society of Infectious Diseases conference on the Sunshine Coast last weekend. The director of microbiology for Pathology Queensland, Dr Graeme Nimmo conducted a seven-year study into the prevalence of methicillin-resistant staphylococcus (MRSA) among outpatients at Queensland hospitals. The results showed there had been a steady increase in the numbers presenting with MRSA. Director of Infectious Diseases at Nambour General Hospital and one of the conference convenors, Dr David Sowden, said these infections were once rarely seen outside hospital wards but numerous studies indicated they were on the march. "There are other studies that show this is happening country-wide and it's becoming a problem in other countries such as North America, with this particular infection being found in the community. "One of the early theories was that people who had been in hospitals were taking it out into the community but it now looks like it's a strain that has evolved by itself." Dr Sowden said he had some seen some limited examples of this occurring the Sunshine Coast. He said it could lead to people developing soft tissue infections such as boils, which were a nuisance but not particularly harmful to a patient's health. At the other end of the spectrum, he said some patients with staphylococcus infections could develop septicemia or pneumonia, which could be life-threatening. Dr Sowden said hospitals could institute isolation procedures when these bacterial infections were detected, but it was more difficult to tackle in the broader community. He said medical practitioners were having to turn to different antibiotics, as strains became resistant to once effective treatments and it was a matter of considerable concern that no new antibiotics were being development. "Once we've gone through what's currently available there's nothing new on the horizon," he said. "Pharmaceutical companies are not spending a lot on the development of antibiotics - presumably because it is time consuming and are very expensive to develop and get the product out there." thedaily.com.au
