Pure culture can be prepared from a mixture of cultures by using the streak plate method. This enables the bacterial cells to be diluted to obtain a pure culture after many-folds dilution.
Pure culture is the one in which only one species, strain or clone of bacteria are grown. The pure culture enables to scientists to study in detail about its anatomy, lifestyle and potential uses or harms, without the interference of any other microbe.
Streak-plate method is the most commonly used technique in microbiology labs to isolate a single type of bacteria. It is performed by creating the smears of bacteria in zig-zag motion to dilute its concentration.

<h3>What is tested for during an amniocentesis?</h3>
Amniocentesis is a test that may be recommended to you during pregnancy to determine whether your unborn child has a chromosomal or genetic disorder like Down syndrome, Edwards syndrome, or Patau's syndrome.
<h3>What exactly does an amniocentesis entail?</h3>
A little sample of amniotic fluid is removed during an amniocentesis operation for testing. This is the fluid that a pregnant woman's fetus is enclosed in. The amniotic fluid shields the fetus from harm and is transparent and pale yellow in color. provides infection protection.
<h3>What takes place after a positive amniocentesis test?</h3>
If the test yields a positive result, the fetus may have the genetic disorder. To confirm this, more testing are sometimes required.
