Heat damage them so you need to be careful already you can dry it on the flame but with keeping a good distamce in order to prevent it from getting hot
Hi, I'm a microbiology student in my second year. If the sample isn't dry first you are likely to boil the bacteria instantly and all your cells may lyse destroying them.
@@CynicalDuty yes but your contaminating the results so thats wrong. Your also a threat to your health. I have got my youtube money hun x there is a protocol and h&s coshh for a reason if you work for any creditied lab or school and see you doing this, you will get reprimanded.

@@zuluzero4659 I'm not too sure which school you are referring to but at Curtin in Perth, in second-year Microbiology we don't use gloves. It is optional. As for the Lab coat yes it is standard PPE and we all need one. The results are not contaminated by bacteria on our hands nor can the bacteria on the stain infect us as it has been made bacteriostatic from use of the gram staining reagents. The bacteria on the slide are in too significant number to be contaminated by our own natural flora. Note also how they have been heat fixed first so our natural flora would just be washed off the slide if it was present.
Why aren’t you using any gloves ? Is it PPE not required ?
why didn't you have on gloves?
I guess it's not necessary
you don't need them
Not necessary because culture is created so no contamination chances in sile by hand
youre dealing with fire, glove is not necessary
Could cause a burn if the glove melts on your hand
why do we heat the mouth of the tube
What do you think would be easier to prepare bacterial smear from, liquid or solid culture?
Send your whattsapp number

It's easier to obtain colonies separately from solid media. It's also more likely to carry unnecessary parts from the liquid media.
I'm confused , is the first drop of water compulsory???
Water is required only if its a solid culture from a plate but not for broth cultures

Great video!
What is the purpose of air drying before heat fixing? Can't the heat fix do that as well as to dry the slide quicker?
The water will boil out and the bacteria will be destroyed.

Air drying preserves the morphology of the cell but heating distorts it.
Why it’s important to air dry the smear before heat fixing?

Why the alcohol is used to clean the slide and not water?
Thank you ❤️😊💯
Thankyou. Doc
Good ❤
इस there bacteria in water and air will not affect it
Vedasi mam ki aaesi ki tasi . 😁😁👍
good
Good video
NO GLOVES ?! OH NO
good job susan
What she took from test tube??
Where is ur lab coat where is your gloves?
chase the bag, don't worry about what i'm doing
