27
the science of investigating small objects using a microscope
Microscopy
28
most common method used for both detection of microorganisms directly in the clinical specimens - and for the characterization of organisms grown in culture
microscopy
29
defined as the use of microscope to magnify objects too small to be visualized with the naked eye so that characteristics are readily observable
microscopy
