Happy to hear that!

[@Nurse4Life255]

Same here

[@taylorcarnes5486]

Thank you this helped greatly!

[@hannaholubaiye2148]

Thank you

[@obieroruth9077]

Perfect 👌. Thanks

[@chingfeng5136]

awesome explaination. Thank you

[@CatalystUniversity]

Glad this helped you!

[@ayat4522]

thanks a lot..its so helpful✨but what is the actual color of macConkey agar ?

[@flavaa9494]

can we grow neisseria lactamica in a maccokney agar or any neisseria?

[@halkerable]

very clear explanation, thanks.
Except staph aureus is a common gram-positive organism and routinely grows on MacConkey agar

[@lmtrevino7]

LB-Amp plate has both blue and white colonies. This is good because you are using a "blue/white" selection. What does this mean and which colonies do you want to pick to grow cultures of?

[@jeffsinko14]

You did a great job with this video and it is good for a basic level. However, please keep in mind fastidious Gram-negative organisms will also not grow on MAC. Therefore no growth on MAC does not automatically mean Gram-positive. An example of some Gram-negative organisms that do not grow on MAC is Neisseria gonorrhoeae and Haemophilus influenzae.

[@iris2874]

Thank you for this video! I feel like I will do great on my exam because of your thorough explanation on MacConkey Agar.

[@IsabelRodriguez-nv2ue]

Very well explained and presented. Easy to understand. Reinforced the concepts with definitions and images. Thanks!

[@williamross5308]

I love how much you repeated yourself in this video. Not being sarcastic, it is my favorite when insructors repeat themselves a few times, it really helps drive home the point and I don't have to rewind or rewatch the video a bunch of times. Thank you, great video.

[@moussamohammed8849]

Very gooood👌🏿👌🏿😁😁

[@mustaphamouallif2767]

great videos. Thanks. Would you tell me please why we are talking about Fermentation "and not respiration" when we describe the Macconkey utilisation of lactose ? especially because of its occuring in an aerobic enviroment which is the surface of the agar.
Thanks so much in advance for your reply

[@moezsuli2782]

Fabulous observations !.
Enterobacteriaceae
Are Aerobes or facultative anaerobes. They prefer fermentation . Rather than respiratorion

[@honeybunchesb23]

So helpful. Thank you ! Keep up the great work of helping students pass micro!

[@sadiatrisha9797]

reviving my knowledges to spread towards my students and this video just made me clear.thank you so much

[@bacteriaxxx19775]

Thank you, excellent explanation, there is Chocolate Agar?

[@Wanis_diary]

Thank you🌹

[@sleverlight]

EMB and MacConkey are selective and differential for coliforms, so we can use both of them for the same purpose right?

[@ryanbrianmbanga3562]

For classifcation, for the (-) lactose, the bacteria is gram negative, but it's still (+) for growth right?

[@otuokwulillian9092]

❤❤❤

[@dinoraf1441]

thank you!

[@ايهاببيانو]

You are amazing, you have helped me alot the best part that I enjoyed when I learned the reason behind the changing of color to pink ♥️ thank you for sharing this information.

[@Scarlett-gq2ln]

I am confused about the uncultured plate color. In my lab it was pinkish. I want to know is it pink or that tan yellow color?

[@monanaveed4687]

S aureus can grow on mac conkey nd its GRAM POSITIVE

[@terriwiley7302]

I have a question that i have problem with, "why would you see only the outer edge of colonies turning red on McConkey Agar? a) the plate has bad neutral red, b) the plate was not incubated for long enough, c) the bacteria have capsules, d) the bacteria don not ferment lactose. I cant find the answer but I think it is the bacteria have capsules

[@SPJ-lm5nq]

Well done

[@amalomer7466]

Simple and sooooo clear.. god bless you really, thank you teacher 🌷🌷🌷

[@LRotter42]

Doesn't MacC agar inhibit G- coccus, but not G- rods?

[@desislavamarinova5902]

How can we distinguish enteric pathogens from normal flora on the MacConkey agar?

[@alijafari4528]

thanks alotof

[@MdEmamHasan]

Could you please upload the media effecacy test/ Growth promotion test procedure.

Very, very helpful!

[@CatalystUniversity]

Thank you, Madison!

[@brentenniss8433]

Very useful, but too long. You repeat yourself too much and all of this could have been covered in less than 2 minutes. If we need repeat, video can be replayed.

[@daniboii3449]

Maybe don´t say the same thing five times in a row next video.

[@mduduziphiri3912]

Extremely helpful. Thanks
