With antibiotics now over-prescribed for treatments of bacterial infections, and patients failing to complete their courses of treatment properly, many bacteria are able to pick up an entire array of antibiotic resistance genes easily by swapping genetic material with each other. MRSA – the multiple drug resistant strain of Staphylococcus aureus - and newly emerging strains of the superbug Clostridium difficile have forced medical researchers to realise that an entirely different approach is required to combat these bacteria. “By using a virus that only attacks bacteria, called a phage – and some phages only attack specific types of bacteria – we can treat infections by targeting the exact strain of bacteria causing the disease”, says Ana Toribio from the Wellcome Trust Sanger Institute in Hinxton, Cambridgeshire, UK. “This is much more targeted than conventional antibiotic therapy”.
