What is the major disadvantage of microbial counts performed by methods other than the serial dilution-agar plate procedure?

The total count includes dead cells as well as living cells.


What is the difference between standard plate count and total plate count?

The white blood cell count and differential determine the number of white blood cells and the percentage of each type of white blood cell in a person's blood. These tests are included in general health examinations and help investigate a variety of illnesses, including infection, allergy, and leukemia. The white blood cell count provides a clue to the presence of illness. White cells protect the body by fighting infection and attacking foreign material. When extra white cells are needed, the bone marrow increases production. There are five types of white cells, each with different functions: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. The differential reveals if these cells are present in a normal distribution, or if one cell type is increased or decreased. This information helps diagnose specific types of illness. Conditions or medications that weaken the immune system, such as AIDS or chemotherapy, cause a decrease in white cells. The white cell count detects dangerously low numbers of white cells. Recovery from illness can be monitored by the white cell count. Counts continuing to rise or fall to abnormal levels indicate a worsening condition; counts returning to normal indicate improvement.


Why Plate Count Agar is used?

it is used to count the colonies


Do both the spread-plate and pour-plate method in a experiment produce similar bacterial counts or are they vastly different?

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

How do you compute colony forming unit per plate?

1.Direct Microscopic Counts (DMC) for both viable and nonviable cells


How do you measure bacteria in a petri dish?

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.

What if your instructor asks you to determine the number of organisms in a water sample observation of your dilution plates reveals?

I think you would eliminate plate counts that are not between 30-300 colonies. <30, because its too few to count, >300 too numerous to count.

What is considered a high plate count?

A high plate count in microbiology typically refers to the presence of a large number of bacterial colonies on a culture plate. The specific threshold for what is considered "high" can depend on the type of sample being tested and the laboratory's protocols. In general, a plate with more than 300 colonies may be indicative of contamination or a high bacterial load.
