On his blog, Mike the Mad Biologist tries to figure out why some scientists do not use positive and negative controls in their experiments. He points to a 2004 study that found 91.3 percent of Streptococcus pneumoniae had a TEM-1 beta-lactamase resistance gene, but was run without adequate negative controls. In June, Mike continues, a paper in the Journal of Antimicrobial Chemotherapy used only negative controls in their experiments and still got positive results due to rampant contamination.
