Why flaming the loop when streaking for isolation?
Flaming the loop when streaking for isolation helps to sterilize the loop by burning off any remaining bacteria from previous streaking or inoculation. This reduces the chances of cross-contamination and ensures that only the desired bacteria are being streaked onto the plate.
U-shaped glas rod in a petri dish?
The U-shaped glass rod in a petri dish may be used for bacterial inoculation or streaking. The unique shape allows for easy manipulation and streaking of bacterial colonies on agar plates for isolation and identification purposes in microbiology. It helps to spread the inoculum evenly across the surface of the agar without damaging the colonies.
Why is it why important to use a needle rather than an inoculating loop when inoculating for a bacterial motility test?
Using a needle rather than an inoculating loop for a bacterial motility test is important because the needle allows for a more precise and controlled inoculation into the medium. This method minimizes disturbance to the growth medium, enabling clearer observation of bacterial motility. The needle can create a narrow stab or line, which is essential for assessing the diffusion of motile bacteria away from the inoculation site, whereas a loop may disrupt the medium too much and complicate the interpretation of results.
Is streaking for isolation and streaking for antibiotic sensitivities uses the same technique for streaking?
Yes, both streaking for isolation and streaking for antibiotic sensitivities use the same basic streaking technique. However, the purpose and method of interpretation are different. Streaking for isolation is to obtain pure colonies of a microorganism, while streaking for antibiotic sensitivities is to test the susceptibility of the microorganism to specific antibiotics.
What is the difference between stab and streaking surface methods of inoculation?
In stabbing, it means pushing the needle to the bottom part of the tube while streaking, it is having a line in a zig-zag manner over the surface of the agar.

Why the loop must be flamed before streaking a new group of lines?
the inoculation loop must be flamed before streaking a new group of line to avoid any type of contamination. This is said to be one type of sterilization(dry heat sterilization) process called incineration.
Why streak in an agar slant medium in a straight line rather than a back and forth wavy inoculation from side-to-side on the slant?
Streaking in a straight line on an agar slant helps to isolate individual colonies of bacteria as they grow. A back and forth wavy inoculation could result in overlapping colonies, making it difficult to observe and identify individual colonies. Streaking in a straight line also ensures a uniform distribution of bacteria across the medium.
Why must it e flamed after making an inoculation?
We use to flame the inoculating loop after inoculation because during inoculation many bacterial cell get attached to loop which can further contaminate the inoculation of other cells so to destroy the previous sticked celled it is necessary to flame burn the loop
What is the basic knitting needle size recommended for beginners?
The basic knitting needle size recommended for beginners is typically a size 8 (5mm) needle.
Which technique is not recommended for needle recapping?
holding the cap in one hand and inserting the needle in to the cap with the other hand is not recommended
Why is a 21 gauge needle recommended for venipuncture?
The 21 gauge is a smaller needle.

What is inoculation chamber?
inoculation chamber is the place free from microorganism where we transfer medium and inoculation.
Is streaking illegal?
no its legal to go streaking
