We need more video about bacteria 🙏
I am a Microbiologist. and I have learnt so much from this amazing video. 🙏 😊 thanks 🤗👏👍
Best videos ever... I can't even express this enough. I hope you know how good you are and how many people you help.. thank you...
Can't thank you enough for this I was about to start this topic today so happy to see this video posted
I tested positive for HSV after having a horrible outbreak, and felt the same way you described in your interview. Listening to you share your overcoming experience gave me the glimmer of hope I needed to hear. I am glad that there are people like you out there who just want to help other people who are struggling with the same issues. Your words gave me the courage I needed to hear today to know that it's ok. I can still be myself and now I'm enjoying my life the way I am supposed to. it is a blessing i came across you drotue channel
These lectures are so high quality,. They are great supplemental material for -paid- third party companies who teach STEP1. I will always be a Ninja Nerd. Thanks Zach
This video was released on my birthday😍 you did amazing as usual! we appreciate you so much
Im currently in Pharmacy School learning about antibiotics/bacterial resistance. THIS HELPED SO MUCH. THANK YOU
This video is fascinating to me both as a nursing student and someone who suffers from mast cell activation syndrome. thank you so much for this amazing channel!
pleaseeeeeeeeeeeeeee, continue this playlist for other bacteria🙏🙏
you're my life savior
Thank You so much ninja nerd team 🙏♥️ you have no idea how many students you are helping around the world ,and you do that effortlessly
Very good explanation and thank you for making this video , such a big help to understand clearly about Exotoxin and Endotoxins.❤️
Beautiful!! I have been reading lots of studies utilizing endotoxin lately!!
Oh man!! To say thank you simply doesn't seem enough!! Deep into my MLT program and as a hybrid student (in person only for labs) this particular course has been a bit of a struggle. Loving this so much! I swear by my near straight A's in my biology and hematology classes because of Ninja Nerd! Thank you!! I agree with below, media lesson (though I have that down) and biochemical testing?? I make my own color coded picture page notes for immunology because of these.
This was so good but I think I'm gonna have to watch it multiple times to actually properly understand and retain it!
I randomely stumbled onto your video sir. I have no microbiology background whatsoever ( i actually study business) but let me tell you that I loved every single minute of your video and learned a lot from it. It took me some time understanding the concepts you explained ( been on the video for over 3h, had to look up definitions that you probably thought were already understood by your viewers but weren't to me ) but you made all of it very clear. You are very eloquent, smily and invested and I thank you enormously for this video. Looking forward to watching more of Ninja Nerd. (not right now though bc it's 2am and I'm exhausted). Keep it up
thank u , i wish u could continue this playlist soon
What a timing, I just finished reading this topic 😍
This is an amazing journey through the human body. 👏👏👍👌🙏
Its really comprehensive and amazing video about toxins.
Thank you Master Ninja! 💓💓🥺🔥
You are feeling the mechanism of bacteria Professor, we just study it(
Thank You very much
This is awesome. Thanks so much!
Thanks my dear lecturer i like how u explain
Very interested in this course so please try to put more videos about microbiology
Amazing explanation😍😍
Thank you💙
Badly needed ❤️
Thank you
Please add more videos🙏🙏
Wonderful lecture 👏👏👏
YOUR ARE THE BEST DOCTOR EVER
AMAZING, THANK YOU VERY MUCH!!!
BEST TEACHER EVER
THANKYOU ZACH❤❤❤❤❤❤
Lol... I'm not even in school. Just love your teaching! You really rock!
You are just too perfect 💖
Very nice explanation.
Can you kindly make a video on LAL test.
Still waiting for the whole series on individual bacteria, viruses, and so on. :)
Sir please make vedios on immune response in tissue damage....or injuries to muscle, nerves etc
THAT was GREAT. Thank uuu!!!!
Thank you so much , you are the best , we are looking for more vid.s about bacteria ❤
Just in time 😍
Podrías hacer un vídeo acerca de temblor neurológico?
fascinating
please sir make all topics video's...i need it so much.
Informative
Thank you 💖
Pleaseeee We need more videos for microbiology about viruses and fungi 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
we Ethiopian love you so much! you are really number one lecturer for us! my lord God bless you to eternity! once in your life we beg you to come to Ethiopia and see you while you are giving lecture face to face!!!! let God give you 1000 years to live on earth
just love it .İ wish you woluld have a fungi video also
Thank you so much
thankyou bro...
GEM OF MEDICINE LEARNING.
Thanks a million
Great ❤️👍
What about techioc/lipoteichoic acids in the cell wall of Gram positives? Granted they are not LPS but they do produce a similar cytokine cascade that can result in shock
Sir,i eagerly need ur notes
You are the best.....
Thank you very much
Thank you ❤❤❤❤❤❤
thanks a bunch.
will you please name a textbook you have read to prepare this video i want to know more about the mechanisms of pathogenicity
Sir can you please share the videos about making solutions * molarity * ppm *
8:50 Does the stimulation of the hypothalamus leading to fever also have something to do with thyroid hormone release, since they are responsable for thermogenesis and are stimulated by the hypothalamus?
Thanx very much NINJA NERD
Can U make videos about general pathology please.
🌸
Thank you
I have a naive question. Can endotoxin tolerance be caused by a sublethal bacterial dose?
Thank you in advance
U r the most aaaaaaawesome teacher everr!!!!
Thank you son much
Hi there! Just out of curiosity, wanted to clear something. At 31:58 you mentioned that a couple of these cytokines increase the production of the prostacyclin PGE2 and so on so forth. My doubt is that (based on a cursory research) is that PGE2 and prostacyclin are different substances so am I misinterpreting something? Thank you! As always, love your videos. My need for them for medical school is absolutely essential.
prostacyclin (PGI2) has a regulatory role within the cardiovascular system, where it promotes vasodilatation and also inhibits platelet aggregation (anti-thrombotic), Also being an important inflammatory mediator.
PGE2 is a direct vasodilator as it acts on smooth muscle to cause dilation of blood vessels. Also inhibits platelet aggregation and suppresses T cell receptor signaling and proliferation, and may play a role in resolution of inflammation.
PGI2 exerts its actions on renal function by inducing vasodilatation whereas PGE2 also has a direct action on tubular function.
Though it's been an year since you asked, hope it helps 🙃
The best
thank you thank you thank you
King in medical sciences
The way you say beautiful :D Gorgeous mind!
Thank you maaaannnnnnn
Beautiful ❤️🥰
I'm confused with Lipid A and polysacharides component of lipopolysacharides. lipid A is pathogenic not immunogenic but polysacharides are immunogenic but not pathogenic
You are too good!😪
Thanks much,from 🇪🇹 Ethiopian
Thanks
great🥰
Genius
Microbiology. Is the basic of Human equipment in the front line of defence.
Should learn, practice you will be in the front line human defence line.
I wish that younger generations concentrate in learning.
please follow-up the scholarship of this field and physiology.
WE LOVE YOU ... ❤❤❤❤❤❤
Please cover the solutions in chemistry 😔
We wait more videos in microbiolog
Tnx Me zach and robbbb🙏🌹
This is wow
type 2 exotoxin just flew through my head
Do cytokines cause fever and vasodilation the same way histamines do?
MORE MICROBIOLOGY VIEOES WILL BE SO GOOD FOR SPECIES OF THE COMMON FAMILES
Wow thanx
Is streptolysin leukocidin from Strep pyogenes or S. aureus?
Your literally so cool
🔥🔥🔥🔥🔥cool
I love u 😭😭❤️
Lipid A-- is that the same thing as Lp(a)??
sir we need mycotoxin video in complete explain
Why Chlorine goes out from the enterocyte to the lumen?
I knew that the concentration of chlorine is Lower in the enterocyte and Higher in the lumen
cholera toxin phospholirases its channels
Should you learn Microbiology deeply
shall lead to becoming , you shall the frontline of all possibilities to control many Microbes in diseases controls.
Amazing explanation love from india 🇮🇳❤️
