Bacterial Identification Tests: Motility Test (Hanging drop method)

[@renish1531]

This video is very helpful i will recommend it to my friends . The motility test was my weakness but not anymore.

[@the_bioway]

I'm glad that this was helpful for you🙏🏼

[@SatyamKumar-tn4nt]

Excellent explanation
Now my concept is clear and I can give viva without any fear
Thank you sir 😊

[@the_bioway]

I'm glad that this was helpful for you🙏🏼
Best of luck for your Viva👍🏼

[@ghaidaghaida3742]

Very helpful. In college we use the play dough instead of cavity slide. I did this experiment 4 times and I couldn’t observe any motility. So my teacher couldn’t give me the mark. I think that’s because we fix the lens on 100x power , I will try again with 40x power. Thanx

Hi direct second year students

[@pavadaiarumugam9723]

Very clear explanation sir. Thank you so much

Sir.. You have to off the bunsen burner flame

[@Youngpharmacist007]

But sir why the video procedure are not displayed?

[@kalanidhih749]

Sir , why we focuse the edge of the drop in this method ? 🤔🤔

[@the_bioway]

There is higher probability of finding motile bacteria due to oxygen concentration at edge

[@kalanidhih749]

@@the_bioway Thanks a lot sir 😊

[@roshangaikwad7962]

“I like your video!”

[@the_bioway]

Thanks

[@vishaltelange8995]

I have a doubt
When we have to observe slide under microscope .from
Which side we can observe
From cover slip or cover slip below the slide

[@the_bioway]

You need to observe from the side where the cover slip is placed.

[@sanarahim782]

Wgat if there isnt any cavity , will we be able to observe bacteria mobility.

[@BalogunRoseline-oj3zn]

Thanks for this wonderful teaching

[@the_bioway]

Glad it was helpful!

Superb sir

[@subhdrasahu3273]

Wow ❤ Sir this was so interesting and helpful🎉thank you so much

Glad you liked it!

[@sethambrose7583]

Sir is there any need of adding safranin in this procedure?

[@the_bioway]

No. Not required

[@rekhashinde7015]

Sir you took another cover slip but didn't applied on slide na 😕

[@ammarsayyed1635]

Awesome video sir

[@akankshamadavi8919]

Plz tell the principle of hanging drop method.

[@ritwikghosh7743]

Thank u Sir. Great explanation. One question, can plasticine be used in place of petroleum jelly?

[@the_bioway]

I'm glad that this was helpful for you🙏🏼
Coming to your question... Yeah you can use Plasticine provided it should hold cavity slide and cover slip properly.

[@ritwikghosh7743]

@@the_bioway Alright Sir, thanks😄

[@rithikmodi4468]

Hi malhari how are u

[@rithikmodi4468]

I love microbiology

[@ritashreebasu9806]

If you open the cover slip with sample of bacteria in air for a long time that u do now then bacteria could be change their character and started to reaction with environmental organisms...how can do u this process... sir??

[@eleven9701]

Sir Do we need to use the fresh broth for viewing motility assay ...or can we use the refrigerated broth also

[@the_bioway]

Freshly prepared one.

[@sumaiyyahashmi6623]

But we are not dropping any thing than why its called as hanging drop method

[@the_bioway]

Because bacterial sample we have taken on coverslip is now in inverted position against the cavity side.... when we we observe it under microscope ... Which results into drop hanging from coverslip

[@Mr_humerus462]

Excellent.. Thank you🙏💕

[@pharmed6914]

Hlo is it possible to view the border in 40x too or in just 10x.. My teacher keeps asking for that in observation.. I'm not really able to get it.

[@the_bioway]

At 40x or 10x you can see only the border but to see bacteria you need to go for higher magnification power

[@ab21234]

Sir we can see any type of bacterial movement through this procedure?

[@the_bioway]

Yes

[@babluyadavbabluyadav8536]

Thanks

[@zahraa6475]

Sir please can Answer me the heating of loop donot kill bacteria ?

[@the_bioway]

Heating the loop kills unwanted bacteria... So it becomes sterile (free from bacteria) and after cooling it...then it can be used to transfer bacteria of our choice....

[@zahraa6475]

Thank you sir god bless you

[@the_bioway]

I'm glad that this was helpful for you🙏🏼

[@priyakotian1264]

No.. We have ro sterilize the loop.. We are doing many cultures and and we have to transfer many of the culture to cover slip.. So we have to sterilize it

[@msdohni9369]

Heating of loop kya huta hai mam

[@arivusaravanan7327]

I have a question
Why do bacteria move in edged

[@the_bioway]

Bacteria move towards edge due to high oxygen concentration at edge

[@arivusaravanan7327]

Tq so much for your certain help.

[@the_bioway]

I'm glad that this was helpful for you🙏🏼

[@anushreekor1648]

Why did u use petroleum jelly only to coverslip?

[@the_bioway]

To make sure only corners of coverslip getting attached

[@abhijeetgome4930]

Blie broth video link send Karo

[@fathielzahra]

How to do this experiment with solid media

[@the_bioway]

You can refer following article for Motility Test using Semi-solid Media
microbeonline.com/tests-bacterial-motility-procedure-results/

[@fathielzahra]

@@the_bioway Tomorrow is our microbiology lab exam. But I'm still confused about making hanging drop from a solid media.

[@the_bioway]

Hanging drop method doesn't use Solid Media.
