can we use streaking around the surface of slective media as selective media use only or qualitative Examination?
Fig. BD Bactec Tryptone Soy Broth bottles freshly inoculated blood specimens for tradition ahead of incubation in BD BACTEC It is crucial to notice that certain formulations or versions during the recipe may well exist based on diverse protocols or laboratory demands.
