ISOLATION OF INDIVIDUAL BACTERIAL COLONIES ON SOLID MEDIA Robert Koch developed a method for isolating pure cultures on solid media in 1883. To this end he added agar (a solidifying agent) to liquid nutrient broth; the nutrient broth supports the growth of a wide variety of microorganisms while the agar provides a solid substrate on which bacteria can be mechanically diluted and therefore isolated as independent colonies representing different bacterial species. The isolation of independent bacterial

Summary The article “NIST Weighs in on EHR Copy-and-Paste Safety‚” discusses the dangers of providers using the copy-and-paste function within the electronic medical records. It also states ways in which the dangers can be avoided or happen less frequently. Many providers use copy and paste when completing their paper work within EHRs but it can cause some significant damage to the patients. The article stated that many times the provider doesn’t proof read the information after it has been inserted
