Your videos are so thorough. You mention lots of extra information that is really useful and you explain the whys and wherefores. It makes life less stressful in the lab when you have an idea of what to do, beforehand (especially for visual learners like me). Thank you for sharing your knowledge!
Better than my micro bio professor. Maybe because she's a woman and seems nicer. My professor is some hot shot with 3 degrees 2 doctorates (young genius) who isn't arrogant at all and is nice but you can just feel the pressure he pushes on you and he purposely makes you feel uncomfortable because he wants to see us lose our cool or see us handle tough pressure. He answers my questions but I feel stupid asking him because he's fast paced and is ridiculously smart. So I like this lady and her vids
If I'm not mistaken, an inoculating needle is for inserting a microbe sample into solid medium. She is taking a sample from the medium, not inserting it.
Hi Rafael1 Well, if you don't allow it to air dry, you are basically boiling the bacteria which can cause the cell walls to distort. This may affect the morphology when viewed under the microscope.
after i do a gram stain on bird droppings and find neg bacteria, how do i determine what kind of bacteria it is? I read that cultures can be done but how exactly do you do that? do i smear a small amount of the same droppings used to do the gram stain on an agar dish and let it grow? and then take a small sample of what was grown to view under the microscope? maybe you can help me even though im sure you have never done this on bird droppings but i bet its all the same steps.
The Heat from Bunsen burner. Its not perfectly clear in this example but you should work close to bunsen burner, the heat/flame creates a sterile zone eliminating contaminants from the air
you'd have to do different cultures in different mediums, because not all bacteria can grow in the same conditions, so you should first have to determinate what bacterias could possibly be and you make cultures based on that, using selective mediums, an example would be that if you had a sample from a sick person's throat and you suspected it to be S. aureus you could do a culture in manitol salt agar
Many Universities do not require you to have one. Like mine, I have 4 labs and in none of them we wear coats. It's kind of awkward, but its just how it is.
You mention even the minutest points, which are critical for success. Thank you.

thank you, my class is doing this tomorrow and I needed a visual to really understand what the words in the book meant.
Have my practical tomorrow. This helped so much, my only regret it not watching these sooner when we were practicing!!
I'm so thrilled my videos helped! Good Luck!!
😭❤️
U a great teacher thanks alot for making me to understand better

she is a great teacher
Thanks so much teacher your videos are helping me so much...my microbiology exam is on monday wish me a good luck ;)
that fly wants to study! it keeps trying to participate.
Excellent useful video thank you,

LMAO at the friggin' fly. What a fantastic teacher.

very helpful lecture
Nice presentation 👍
Thank you so much for helping us
I have microbiology exam on Monday
And professor u saved me
Where can I easily get bacteria at home? Also, I take it the flame is what stains the bacteria?
I need to re-evaluate my life, I've been doing everything wrong........
thank you very very very much prof. :)
I wish you were my teacher...
Thank you very much. It is really helpful for my micro. lab test next week.
Hi! Great video. Why do we air-dry before heat-fixing?
Hi Rafael1 Well, if you don't allow it to air dry, you are basically boiling the bacteria which can cause the cell walls to distort. This may affect the morphology when viewed under the microscope.
@@bioprofaz thank you so much! I’m trying to survive pandemic microbiology lab
@@Recp888 How exactly does that work? Is it online?
@@bioprofaz yes, sadly. Very autodidactic, and we watch videos of procedures.
Tldr; A lot less fun.
very thorough, excellent

very helpful tutorial, thank you
Watching now at 1 21am for first exam in 8hrs later in the morning.
Wait... Aren't you supposed to use an inoculating needle for a solid medium?
Thanks, this is a big help!
2020 - you are amazing!!
Watching from Israel
You are the BEST!!!!!!
thanks for the info, i guess its much more difficult than i thought. there are so many types of agar, and my research continues lol ")
why doesn't the surrounding air contaminate the smear?
The Heat from Bunsen burner. Its not perfectly clear in this example but you should work close to bunsen burner, the heat/flame creates a sterile zone eliminating contaminants from the air
...made me wanna bunsen burn that fly!

she just suddenly walked away.
@SecretCommie nono, bad!
Thanxxxxxxxxx its verey good smear
Thank you .. GOD bless you 😍
She's professional.
very effective, thanks
You. are. great.
when your cleanroom has a fly in it
Is there a way I can get live bacteria on the slide?
Micros cope
this is good thanks alot dia
What if the bacteria is in a Petri dish, how would you do it?
At least you didn't wind up in the weird part of youtube.
Try using chopsticks to catch the fly and smear it on a plate. :)
where is your lab coat
Where is your lab coat?

how did i get from minecraft to this?
Wow ❤
nice
Where's the coverslip at the end?
No cover slip for gram staining.

You don't have to
I promise not to tell any smear about you !

you look mean
This is so long winded. Just do it. Stop talking and just DO IT! 7 minutes in and you've still not actually done anything omg
