Is streaking for isolation and streaking for antibiotic sensitivities uses the same technique for streaking?
for isolation parallel method can be used and for antibiotic sensitivity ray method used
What is the purpose of the streak for isolation?
By using streak plate technique to spread a clinical sample out on the surface of a growth medium individual types of bacteria can be isolated
What is the simplest technique for isolating bacteria in growth media is referred to as the?
Streak-plate method
What is Moissan's method for isolation of fluorine?
Fluorine was obtained by the hydrolysis of a mixture of KF2 and HF.
Where do you get the DNA fragments for Gel electrophoresis?
The DNA fragments comes from the method of DNA isolation.

The purpose or objective of streak plating is what?
to under stand the principle of bacterial isolation
What advantage does the streak plate method have over the pour plate method?
A disadvantage of the streak plate technique could be colony isolation problems. If the streaking technique is not done properly or if there is too much of an organism present on the inoculating loop then the cells can cluster and form what looks like one colony but it can actually be a couple colonies (made from a couple cells). This can cause an inaccurate colony forming unit count.

Why is the production of an isolation streak key to the identifcation of a bacterium grown in culture?
Isolation streaking was first introduced by Robert Koch as an improvement on the dilution method of isolation of bacterial cultures. Isolation is achieved by taking a minute sample from within one bacterial colony and putting it in a sterile medium so that only that organism will grow. The assumption here is that a bacterial colony has ways of ensuring that no other bacteria will grow within its colonies, primarily by the use of antibiotic compounds that it produces and secondarily by the fact that it will consume available medium before any other organisms can establish themselves. Contamination of a sample by bacteria other than the one desired can lead to improper identification and poor test results. Good isolation such as that provided by the isolation streak method addresses this concern, is cost-effective, and produces acceptable results.
What is isolation media in microbiology?
The growth media such as nutrient agar or Mckonkey agar is used to isolate microbial cells from the mix culture when inoculate on them. Some time speical media is used which selectivly grow some time of bacteria or a differential media which give different morphology of different bacterial species e.g. blood agar and Mannitol salt agar. It can be done by three ways: the spread plate method, the streak plate method, and the pour plate method.
What is the criteria for a good quality streak plate?
In scientific circles, the streak plate method is considered to be a rapid qualitative isolation method. To be effective, one must reduce the number of organisms in the inoculums by spreading a loop of culture over an agar plate. This ensures that individual cells are properly separated on the surface for the purpose of differentiating various species. The method is as follows: Using a sterile loop, microbes are initially transferred to the plate with one swipe. On the subsequent swipes, the loop is heated in the flame of a Bunsen burner to lessen the population of microbes being transmitted. Streak patterns are also done in via T-streak or by applying the loop to four quadrants of the plate.
Does the streak plate method work better than the pour plate method?
I 4 got
What is An alternate method to universal precautions?
BSI, or Body Substance Isolation.
What advantages does the streak-plate method have over the pour plate method?
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.
