Laboratory Studies with a Selective Enterococcus Medium 1

摘要: Lancefield group D streptococci are involved with appreciable frequency in a variety of infectious processes. The presumptive recognition these bacteria on initial culturing clinical specimens is an objective not attained readily by selective media available the laboratory. Selective Enterococcus agar was evaluated emphasis its ability to sequester enterococci from many microbial components. In addition, sensitivity this new compared Trypticase Soy containing sheep blood and Mitis Salivarius agar. All isolated material were classified accordance accepted biochemical immunochemical criteria. grew medium as distinctive colonies surrounded black zone. Only Listeria monocytogenes presented similar colonial morphology after 48 hr. Most other did grow at all or appeared markedly different. same order magnitude Mitis-Salivarius agars, but selectivity superior.
