Chromogenic media are being used now-a-days for identification of many microorganisms in the clinical microbiology laboratories. They are being used for screening purposes especially in case of urine cultures, environmental surveillance and also for detection of multidrug-resistant organisms like Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococci (VRE) and Carbapenem-resistant Enterobactericeae (CRE) etc. Organisms produce specific colour due to digestion of chromogenic substrates present in the medium. Thus the Organisms are identified on basis of colour production. These media are specific in detecting common pathogens which are isolated. But they can give different results when uncommon organisms are encountered. In this case report the uncommon organism that is Stenotrophomonas maltophilia produced colour similar to Klebsiella spp. on chromogenic media.
