counter. Two of the most common procedures used in microbiology are discussed below. Direct Count Using a Counting Chamber Direct microscopic counts are performed by spreading a measured volume of sample over a known area of a slide, counting representative microscopic fields, and relating the averages back to the appropriate volume-area factors.

The number of bacteria in a small sample can be startling; for example, there are approximately 107 10to 10 bacteria in every gram of human feces! (That’s 10,000,000 to 10,000,000,000 bacteria per g) Direct microscopic counts of bacteria are impossible when the concentration is so high, therefore, dilution of the sample is necessary.
