I wish I'd had access to this channel in 1962 when I was 8 and my grandfather bequeathed my most valued gift ever... a beautiful Bosch&Lomb microscrope. Changed my life. for the better :)
My Uncle in his 90s had blood poisoning when he was around 5, he was bitten by a dirty South Boston Crab and he told me he watched a line form that went from the cut on his foot up his leg, he didn’t remember how he got home or how he got to the hospital. He also told me they had no penicillin and they were injecting him with a black fluid. He said he almost died. It surprised me that they didn’t use penicillin. It’s something we take for granted but many of us wouldn’t be alive today without the help of antibiotics.
Microbiology was hard work in med school and you needed to be well caffeinated for the lectures , this is just great, well presented, historically accurate and entertaining. Excellent work.
Well, my dad was a pharmacist apprentice in the 1930'ies and he handed over Salvarsan to regulars from the navy - that had been in Danish colonies in their youth - and naturally caught syphilis - which in practice meant that they for the rest of their days had to take antibiotics (Salversan). The problem was: a) The side effects of Salversan was no joke. b) Salvarsan had a notoriusly low toxic index - meaning that the differnce between effective terapeutic dose and toxic dose was low - just about a factor of 10. The contrast to penicillin is staggering. The point being that with increasing bacterial resistance to penicillin - the remidy is simple: Ooumph up the dose - penicillin is incredibly non-toxic. It has allway been a mystery to me, that sulphonamides have not stayed on the repertoire: Simply because the working mechanism of sulphonamides and penicillin is so totally different. The point being: A combination treatment gives the bacteria not one, but two problems which they have to evolve away from simultaneously. It also shows that "difficult" diseases from mycobateria like tuberculosis and Hansens diseasy do need a combination terapy with more than one weapon. Same thing for HIV (though it is not a bacteria). How incredibly effective penicillin is shown by the temperature raise at the start of treatment - the bacteria are blown up by the aminoacids having a chiral - which creates a weak point the cellular wall of the bacteria - which is like a nail in car tyre. As soon as the pressure goes up the organism explodes and its enzymes float around - and as enzymes are VERY temperature specific in their working the immunesystem ups the temperature - known colloqualy as fever.
I had an unfortunate episode in my life, long story short my fridge was a mess. Anyway, I could witness how Camembert mould on half a cantaloupe would prohibit any other mould nearby. That was kind of cool.
12:03 “Aspirin 5 grs.each” scared me for a second, thinking those tablets were _5 grams_ each! That would be more than 16× the strength of modern 300 mg tablets here in the UK, and 5.5× the maximum recommended dose (900 mg). _Per tablet._ Yikes! 😮 … But then I remembered that drugs used to be measured in _grains_ 😅 So those tablets are only 8% stronger than those I buy today - assuming my calculator's “1 grain = 64.79891 mg” is accurate and definitions haven't been changed in the intervening decades. That makes 5 grains = 324 mg. … and that probably explains why the aspirin tablets my housemate brought back from the USA were 325 mg instead of 300 mg. What a fun rabbit hole that single image sent me down! 😹 And yes, great work as always!
Yes, grains are an old measurement, so many in an apothecary pound (the sole surviving measurement of that is the Troy ounce), and so many more in a flesh pound (the measurement still of the US, and understood 'round the English speaking world). They are the same grain. Aspirin (in the US) is primarily, that is most often, dosed at 325 mg. Also, that is the dose doctors recommend for those suffering a heart attack. If you are having a heart attack, i.e., take that much aspirin.
Interestingly though, we still have some medications formulated in grains over in Europe. I'm not sure US. They're being phazed out overall, for better alternatives. But they're still out there. It's always fun to see them Tbh. @@PatKellyTeaches
I love love love that you went so deep on the dye innovation that was happening. Staining is such an important and ubiquitous part for any kind of microscopy and has only grown more sophisticated over time that by now with a great number of methods we can design system that very specifically delivers a dye to any part of the cell that we want and thus confirm the presence and precise location of a target. The general public might not know this but cells really aren't that colorful. Even a very vibrant orange carrot only has a very tiny amount of orange carotenoid in each cell that is mostly clear.
With Jenner, Pasteur, and Fleming as my heroes, this channel is golden. I studied biology in school only but, this topic comes off to me as a culmination and the highest goal of both chemistry and biology. Indeed it takes a lot of creativity which is why I love it even though I am from the engineering background with a touch of design.
A little note. Semmelweiz didn't just use soap, they washed their hands with a kind of bleach knowing that more than simple mechanical removal was needed.
@@PatKellyTeacheshis story is also incredibly sad - his peers did not listen to him and it eventually led to a nervous breakdown and he died from an infection in the asylum he was admitted to - allegedly due to beatings from the guards there. Only after Lister and Pasteur his work was appreciated.
RUclips just showed me your videos/channel a few days ago, and I'm thoroughly enjoying your content. Extremely interesting. I'll have to watch more as time allows. Keep up the great work.
I just watched all of your videos in one go. So much information, but so very interesting! Thank you so much for all of your research and knowledge. Keep up the great work!❤
Great video, Patrick! I love your work on the history of medicine and I'm anxious to see your development! As a pharmacist that graduated recently I must say that the context that you give was missed during my time studying(haha)!
Methylene blue mentioned around 15:25 is a dye which i use at my work in a brewery regularly to check for yeast viability (a.k.a. see how much of the yeast is still alive (dead yeast=blue)).. from what i know methylene blue still has some medical aplications to this day.. Treating methemoglobinemia.. which is a misfolding of hemoglobine in blood causes the skin to appear blue and debilitating the oxygen transport... always found it funny that theyre fighting blue with more blue.... also methyleneblue is an antidote to cyanide posioning.. but people tend to die rather quickly from that. I dont think it gets used much for this last purpose... alright, enough trivia
It is also the end product (tested colorimetrically for light absorption) in some forms of analytical sulfide testing (to monitor the poison H2S, common in wastewater and anaerobic systems)
It's used in aquaculture and aquarium keeping too, not a fish keeper myself but I've seen goldfish owners use methylene blue used to disinfect goldfish and get rid of tumours and masses that grew on them
I’m enjoying my last few days of unemployment by bingeing this channel. Thank you for the incredible research, presentation, delivery, and editing. This is how I felt when I found Tasting History with Max Miller 😊😊😊
When I was young, I had to use coal tar to treat my psoriasis. I hated it. It made my elbows look dirty. Eventually, they came out with a version that was yellowish and didn't stain. It still smelled like hot asphalt. 😂 I was so happy when they came out with something besides tar.
Great video, antibiotics and how they work was something I was always interested in but only whenever I had to take them and wasn't usually in the mood to find out how at the time. The concept of the magic bullet for a subfield of medicine seems common, last night I heard the phrase in regards to when chemo was first developed and similar hopes about it.
Soap doesn't kill bacteria? Detergents go to town on membranes as far as I know, leading to the collapse of the cell. I'm really confused on why half the links on google just say it washes off cells (even a Harvard link). I work with bacteria and if soap would just allow them to not stick to plastics and glasswear it would be great.
Very interesting video! This year I had a chance to attend a microbiology class and this video was a great summary of the subject of antibiotics! On 8:15 probably the right word would be cytotoxic instead of antiseptic that is the name of the antimicrobial products we can apply on a living tissue =D
Watched a few of your videos now and im impressed by the quality and how easy the videos are to follow. How in the world do you not have more subscriptions! Anyways you got 1more, keep going .
I had Strep Throat once and Bronchitis 4 times and needed to take antibiotics each time (one time of Bronchitis it took 3 or 4 rounds of antibiotics to get rid of it).
I’ve read of ancient cavalry using the mould off the leather on the underside of their saddles to pack into wounds to cure infection. I’ve also heard of a “broth” made from old bread (mouldy bread) being used in some medieval medicine (that was not controlled by the Church). Of course, use of cobwebs was a common anti coagulant and, in my youth, my Father “doctored” us using poultices he packed with various things from the bush, including stuff from the forest floor.
Recently discovered this channel and I'm absolutely loving the accessible way you explain this info! Love listening to your vids while working, keep up the good work 👏 😊
Exceptionally interesting and high quality content. Hello from a new sub and patron. Im looking forward to adding you into my watch on release rotation. Your presentation style in particular is excellent, well paced and the right amount of information to inform but not overwhelm.
I love how often different people are mentioned by name, and you can remember their last name from some random medical term. It's like watching a video about the history of trade, and suddenly some guy named Jonathan Money is mentioned
😊love your style of learninng and i really want to learn more virology and biochemistry and you present the technical parts into laymans terms😊 great channel
You dude are awesome. I’m fascinated with the history of medicine and I’m a student of forensic science so all this is really interesting. Earned a subscriber!
Has anyone here ever had c.diff?? I had it while in the hospital. It dam near blew out the blanket and put a splatter on the wall a couple feet away. You'd think i just got done mud wrestling because due to the sedatives, by the time i woke up everything was well underway 😂. I even let a few blasts go while they were washing me off in the shower. I felt bad for the tech, but he was a trooper, if he was bothered, he didn't show it. I will never forget the smell it is unmistakable
There is an antibiotic effect from most soaps even if they don't claim to be antibacterial. It deals with how the molecules of the soap are so aggressively polar that they will burrow into and even though the cell wall of bacteria. No it's not as effective as other things but it is true.
I'm not really convinced that the "made by microbes" criteria is still relevant. Whether it's originally synthesized through artificial chemistry, naturally by microbes, or synthesized to copy something made by microbes, it's the selective function of the compound that determines its application to bacterial infection, not the manufacturing process.
I love the trailer for Dr. Ehrlich's Magic Bullet! ("Forged in the white fires of one man's courage!") Has anyone watched the whole thing? Do they actually mention the word "syphilis"? Did the Hays Office allow that?
7:58 It was sodium hypochlorite, not soap. Soap might have been good enough but it didn't remove dead body stench and the stench itself was thought to cause childbed fever.
Is the oligiodynamic effect still controversial? Like I assumed literally throughout my life that was how mercury was effective, due to the oligiodynamic effect. Silver is another more commonly demonized oligiodynamic effect heavy metal, albeit safest seems of the useful bunch outside of the human nutrients that still cane be dangerous in higher dosages. Yet during my questioning of and tenure at Perrigo and later, silver became more available on the market outside of burn dressings. I also assumed that is why the door and rail materials were made from the specific metals. Maybe a Wiki search for oligiodynamic effect and go from there maybe? Now I'm wondering about the research, or lack there of, in regards to USP NF treatments active ingredients that were pre WW2.
I would find a weird coincidence that the ancient doctors used mold if it had no effect. Where would they have gotten the idea? Now the effect may have been small.
The reason most life needs cell walls but animals don't is that we incorporate cholesterol in the cell membrane which increases its stiffness & strength.
I think you mixed up fox gloves (digitalis) and belladonna (atropine) when you said the heart effects of belladonna and the anti inflammatory effects of fox gloves. Of course maybe I’m missing something.
Totally fair comment. I'm oversimplifying a bunch, but digitalis was used for a condition old-timey doctors called dropsy (swelling now more commonly associated with heart failure, not general inflammation) while atropine is used to *increase* heart rate
Mhmm, I call him Alexander after the discoverer of the plague bacillus, Alexandre Yersin. It's this one here: www.amazon.com/Squishable-Mini-Plague-Doctor-Plush/dp/B08F5KQFXJ?&_encoding=UTF8&tag=corporis-20&linkCode=ur2&linkId=1a30387aeac44d700145d7321f3aef7f&camp=1789&creative=9325">Plague Doctor squish mallow
I mentioned this in another comment, but foxglove's primary use (before digitalis was isolated and used in Digoxin) was against an old-timey condition called dropsy, which was edema, probably associated with heart failure. And belladonna's main active ingredient is atropine which raises heart rate.
To be an antibiotic the idea of microbes must exist. I know Arabs and some Indigenous nations of the US knew how cure infections using antibiotics but I don't know if they knew about microbiology. BTW, there's a book called "The Secret Of Our Success" by a Harvard evolutionary biologist that talks about that - and much more! NOTE: it's not a self help book.

I was taught A level biology by Alexander Fleming's granddaughter. Awesome teacher.
After 45 years of no problems, I'm now allergic to penicillin.
See my comment.
Given penicillin many times as a child. 20 years later an abscess tooth, penicillin gave me hives.

I also assumed that is why the door and rail materials were made from the specific metals. Maybe a Wiki search for oligiodynamic effect and go from there maybe? Now I'm wondering about the research, or lack there of, in regards to USP NF treatments active ingredients that were pre WW2.
Great videos by the way! Looking forward to seeing your channel growth.
Why is the 4th video on this series hidden??
I'm not sure. I originally had a Patreon exclusive video in there, but have since deleted it
I would find a weird coincidence that the ancient doctors used mold if it had no effect. Where would they have gotten the idea? Now the effect may have been small.
The reason most life needs cell walls but animals don't is that we incorporate cholesterol in the cell membrane which increases its stiffness & strength.
I think you mixed up fox gloves (digitalis) and belladonna (atropine) when you said the heart effects of belladonna and the anti inflammatory effects of fox gloves.
Of course maybe I’m missing something.
Totally fair comment. I'm oversimplifying a bunch, but digitalis was used for a condition old-timey doctors called dropsy (swelling now more commonly associated with heart failure, not general inflammation) while atropine is used to *increase* heart rate
What’s the adorable plague doctor stuffies name? I notice he’s ever present there behind you on the table.
Mhmm, I call him Alexander after the discoverer of the plague bacillus, Alexandre Yersin. It's this one here: www.amazon.com/Squishable-Mini-Plague-Doctor-Plush/dp/B08F5KQFXJ?&_encoding=UTF8&tag=corporis-20&linkCode=ur2&linkId=1a30387aeac44d700145d7321f3aef7f&camp=1789&creative=9325">Plague Doctor squish mallow
It would have been something unknown to science at the time probably. A traditional medicine of one type or another from somewhere or other.
Always assumed Gram stain was related to the size or weight of the bacteria, no one ever explained its just named after a guy.
That’s what I thought at first too! I always have to remind myself to capitalize Gram when I spell it out
Didn’t u mix up foxglove and belladonna effects?
I mentioned this in another comment, but foxglove's primary use (before digitalis was isolated and used in Digoxin) was against an old-timey condition called dropsy, which was edema, probably associated with heart failure. And belladonna's main active ingredient is atropine which raises heart rate.

big guy, you didnt link the campy trailer
Thanks for the shout. I fixed the end card and it ought to show up now: ruclips.net/video/jEQmqugPiTw/видео.html
To be an antibiotic the idea of microbes must exist. I know Arabs and some Indigenous nations of the US knew how cure infections using antibiotics but I don't know if they knew about microbiology. BTW, there's a book called "The Secret Of Our Success" by a Harvard evolutionary biologist that talks about that - and much more! NOTE: it's not a self help book.
