Bacteriometry
Definition
A method or body of laboratory techniques utilized for counting, measuring dimensions, or determining the density of bacterial colonies within a given volume of a liquid, solid, or gaseous sample. Biochemically and industrially, bacteriometry includes direct methods (microscopic or culture plate counting) and indirect methods (nephelometry, turbidimetry, or flow cytometry) necessary for quality control.
