FDA approves first rapid MRSA test

The U.S. Food and Drug Administration (FDA) has cleared a quick test that within five hours can determine whether a patient is infected by methicillin-resistant Staphylococcus aureus (MRSA) or methicillin-susceptible Staphylococcus aureus (MSSA). The test uses bacteriophages that selectively infect particular bacterial species. Some of these viruses specific for bacteria can differentiate MRSA from MSSA. In the laboratory, the samples are mixed with special phages that within a few hours grow inside the bacteria and are released in large quantities. MSSA and MRSA can then be detected and differentiated by special reagents. The results are available within five hours only, as the bacteria do not have to undergo time-consuming cultivation. The FDA’s approval is based on a clinical study of 1,116 blood samples from four major U.S. hospital centres. In this study, the MRSA determination was 98.9% accurate (178 out of 180 blood samples), for MSSA the determination was 99.4% accurate (153 out of 154 blood samples).
