Infection prevention has been an issue that is getting more and more attention over the last decades, possibly because of the fact that healthcare associated infection (HAI) have great impact on the patients and the healthcare workers involved. For the U.S. it is estimated that 1.7 million patients suffer from an HAI each year and from these, about 99,000 patients will die because of that infection. In the Netherlands, about 27,000 HAI where seen in 2007-2008 and it is estimated that 1500 of these patients did not survive this infection. Because HAIs are diseases that can be mostly prevented by taking appropriate (hygiene) measures, studying these infections in more detail is important.
