- Environmental monitoring involves sampling from various surfaces for microbiological quality. For example, laboratory surfaces, product contact surfaces, floors, walls, and equipment should be tested on a regular basis. Swab Technique has been commonly used for such tests. This technique is very important for microbiological laboratories and food & drug production units. This video explained the detailed procedure of swab techniques.

thanks a lot. all these videos were very helpful.🥰🥰
Hi can you show how to do and intepret/read contact plates for environmental surface sampling? Thanks
I love you for your work ❤❤
Thank you. Stay with us
Thanks
Please make a video on detection of campylobacter
Is that right (9x10x10)/100cm2
Cause you have diluted twice
Thanks for the video! May I know is there ant reason for using 2 cotton stick to swab 2 directions ? Can I use the same stick for both direction. And, do you know what type of bacterial is on the plate? I often saw similar bacterial colony on my agar plate but I am not sure what type of bacterial it is.
Yes. You can use same stick.
Type of bacteria depends what we used for the broth culture preparation. We must know the bacteria name and identity. If you work with unknown bacteria then you could know by the bacterial identification tests (biochemical, immunological and molecular tests).
Plz make an video on salmonella, shegilla and s. aureus species testing by swab method
Noted.
Thanks you
You are welcome
Base on which u done in this procedure?
Please, create a video on Shigella species detection.
Noted
For hand swab same procedure shld followed??
Yes
Instead of TSA can I use plate count agar
You can
What is procedure if swabbed area is not possible to measure...in food industry many areas where is not possible to measure by using template like tubes, bends etc....at this situation what we can do...
Swab the whole surface and calculate using the surface name, as CFU/tube, CFU/bends
Based on which standard u have done this?
FDA
Can we use PBS buffer for swab test?
Yes. You can use
I am Microbiologist help full video
Do you have any article that supports this formula?
Please find from journal websites
Could you please refer any article using same formula? @@MicroChemsExperiments
mam, can you create video about how to autoclaf your media ?

How to check talcum powder surface?
You need different mechanical device or instrument
@@MicroChemsExperimentsNo sir i don't have any equipments. Iam working at soap industry . so that iam asking how to check talcum powder surface using chemicals titaration method or any other options
Why saline solution is used
Culture suspensions are prepared in saline solution because 0.85 % sodium chloride solution is isotonic in nature. Normal saline solution is routinely used as a diluent to adjust the turbidity of bacterial cell suspensions to help maintain cell integrity and viability.
please describe the reference document.
This is a FDA method
Can you told us where can find the method. I can find it. Please cited..@@MicroChemsExperiments
@@MicroChemsExperimentswhat number in FDA
9×10×0.1=9 /100= 0.09 right
Can you explain ur calculation
Sorry, we can't explain here. We will develop a video later for chemical reactions and calculations. Stay with us.
Can i get reference of this method please

Thank you for the clarification ♥️♥️
@@wesleychebii5684 you are most welcome
9×10×0.1 =9 /100= 0.09
can u explain this calculation
Hello, what to do if the surface i will swab is in the gym equipments. Like how many hrs it will take for the swabbed samples to tranpsort in the laboratory? Fyi i am the researcher
Please write us in details at mail.mic.chem@gmail.com
How could plastic vials survived in 121 degree temp. 😮
Those plastics are autoclavable in quality to survive 121 degree Celsius moist heat
Wrong calculation formula, 0 .1 will be on denominator, Rest video is good.,
Superb. You are right. We did mistake here. Sorry
Hi, so may I know what is the correct equation and right answer?
