Per the article, these bleach (sodium hypochlorite) resistant spores are a HUGE problem. At my office, we clean surfaces with quaternary ammonium compounds, and those are supposed to be superior against spores. But still, if the required contact times to disinfect surfaces keep increasing in healthcare settings, we are going to have a major issue where only the most resistant spore-forming bacterial strains survive (basically, we'll be selecting for the strongest... you know, evolution).
