The Petrifilm plate method is a widely used technique for microbial testing in food and beverage industries. It involves placing a sample on a pre-sterilized thin film that contains a growth medium, allowing for the detection and enumeration of specific bacteria or molds present in the sample. The results are typically seen as visible colonies on the film, making it a convenient and efficient method for quality control purposes.
Rober Kock developed the culture plate method to identify pathogens.
It is necessary to make the colonies well-isolated from each other so that each appears distinct, large and shows characteristic growth forms.Most bacteria, many other microfungi, and unicellular microalgae, may be most commonly obtained by plating methods such as streak plate method, pour plate method and spread plate method.
Satellites are used to measure the movement of plate by radiation.
American microbiologist Robert Koch is credited with discovering the streaking method in the late 1800s. This method involves spreading a bacterial sample on an agar plate to isolate individual colonies for further study.
Previous answer: "because of infection" This person is obviously trying to be funny, the right word should be "Contamination", as for spread plate, the bacteria is more exposed to air as it is spread over the agar plate. Therefore, the result might not be accurate, as it might be contaminated. As for the pour plate method, the bacteria is in the agar itself, it is not exposed to air, thus, less risk of getting contaminated.

In the pour plate, the microorganisms will grow within the gel that has been set, and in the spread-plate technique, growth will be on top of the agar gel where it has been spread.
The streak plate method makes it easier for colonies of bacteria to grow. It also generally leads to individual colonies that look like small dots, rather then simply a mat of bacterial growth.

Both Spread-plate and pour plate method don't give the same results. Because in the case of spread plate method the inoculmn used for inoculation can't be spread in a exact volume. A little inoculmn remains stick with the spreader after spreading. On the other hand, in pour plate method it doesn't happen. So mostly, through comparing the counts by both methods, less counts are obtained in spread plate method. I am Working as a Sr. Microbiologist in a Biotech company
Pour plate method
When bacteria is grown in an Agar plate, one quantitative method to measure growth is using a counting chamber. Another method is using viable plate counts.

Replica plating method.
Linear patterns of earthquakes is one method of detecting them.
