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...
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
Can't thank you enough for this I was about to start this topic today so happy to see this video posted
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
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!
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
pleaseeeeeeeeeeeeeee, continue this playlist for other bacteria🙏🙏
you're my life savior
This video was released on my birthday😍 you did amazing as usual! we appreciate you so much
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.
Beautiful!! I have been reading lots of studies utilizing endotoxin lately!!
Very good explanation and thank you for making this video , such a big help to understand clearly about Exotoxin and Endotoxins.❤️
What a timing, I just finished reading this topic 😍
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
This was so good but I think I'm gonna have to watch it multiple times to actually properly understand and retain it!
This is an amazing journey through the human body. 👏👏👍👌🙏
thank u , i wish u could continue this playlist soon
Badly needed ❤️
Thank you Master Ninja! 💓💓🥺🔥
You are feeling the mechanism of bacteria Professor, we just study it(
Thank You very much
Lol... I'm not even in school. Just love your teaching! You really rock!
Its really comprehensive and amazing video about toxins.
This is awesome. Thanks so much!
Thanks my dear lecturer i like how u explain
YOUR ARE THE BEST DOCTOR EVER
Very interested in this course so please try to put more videos about microbiology
GEM OF MEDICINE LEARNING.
AMAZING, THANK YOU VERY MUCH!!!
BEST TEACHER EVER
THANKYOU ZACH❤❤❤❤❤❤
You are just too perfect 💖
Love you ,man!
Amazing explanation😍😍
Thank you💙
Thank you so much , you are the best , we are looking for more vid.s about bacteria ❤
will you please name a textbook you have read to prepare this video i want to know more about the mechanisms of pathogenicity
THAT was GREAT. Thank uuu!!!!
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
Still waiting for the whole series on individual bacteria, viruses, and so on. :)
Just in time 😍
You are the guy!!!!!!!!!!!!!!!!!!!!!!!
Thank you.
Thank you 💖
Thank you
Please add more videos🙏🙏
You are the best.....
just love it .İ wish you woluld have a fungi video also
King in medical sciences
I have a naive question. Can endotoxin tolerance be caused by a sublethal bacterial dose?
Thank you in advance
Thank you so much
Thank you very much
This was very helpful. till waiting on thar Streptococcus pyogenes individual video though.
thanks a bunch.
Wonderful lecture 👏👏👏
please sir make all topics video's...i need it so much.
U r the most aaaaaaawesome teacher everr!!!!
Pleaseeee We need more videos for microbiology about viruses and fungi 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
Sir please make vedios on immune response in tissue damage....or injuries to muscle, nerves etc
Thanx very much NINJA NERD
Great ❤️👍
Thank you
Thanks a million
Thank you ❤❤❤❤❤❤
Very nice explanation.
Can you kindly make a video on LAL test.
Podrías hacer un vídeo acerca de temblor neurológico?
thankyou bro...
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?
fascinating
Thank you son much
I'm confused with Lipid A and polysacharides component of lipopolysacharides. lipid A is pathogenic not immunogenic but polysacharides are immunogenic but not pathogenic
thank uu so much sir
Informative
thank you thank you thank you
We wait more videos in microbiolog
Sir,i eagerly need ur notes
Thanks
Sir can you please share the videos about making solutions * molarity * ppm *
The best
You are too good!😪
MORE MICROBIOLOGY VIEOES WILL BE SO GOOD FOR SPECIES OF THE COMMON FAMILES
Thank you maaaannnnnnn
Thanks much,from 🇪🇹 Ethiopian
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
This is wow
WE LOVE YOU ... ❤❤❤❤❤❤
Do cytokines cause fever and vasodilation the same way histamines do?
Lipid A-- is that the same thing as Lp(a)??
Wow thanx
great🥰
Is streptolysin leukocidin from Strep pyogenes or S. aureus?
type 2 exotoxin just flew through my head
Genius
I love u 😭😭❤️
Beautiful ❤️🥰
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 way you say beautiful :D Gorgeous mind!
Tnx Me zach and robbbb🙏🌹
Can U make videos about general pathology please.
🌸
Please cover the solutions in chemistry 😔
Your literally so cool
Amazing explanation love from india 🇮🇳❤️
🔥🔥🔥🔥🔥cool
