PDE: Let's get into some Plague-
WHO: Wait, that's illegal.
I thought black death killed 200million
cruise ships are our modern version of those wooden boats that reached shore in 1347
i just started reading a book called Between Two Fires set during the black death (1348). it's fiction, "medieval horror," it's awesome so far highly recommend. But that's how I ended up here. I already love prof. dave and I was on the wikipedia page for the black plague, and i ran across Yersinia Pestis and wondered what youtube results there'd be for specifically "yersinia pestis." was quite happy that professor dave was the first result, awesome video. I like that it is both casual but also informative like a lecture. great combo.
Talking about plague when subscribers hits 666K?
Priceless...
Great info, Professor. Thank you for uploading for the rest of us to learn from.
Untreated pneumonic plague is not 90% but almost 100%. In the Manchurian outbreak (1911) out of 60 000 patients that were infected, it is said only 2 survived the disease.
Great Sir your videos help us in every step of microbiology
Hey professor Dave, can you make videos about the s block, p block, d block and f block elements, like their general properties and the important compounds?
Thanks prof. I wish you all the lucks.
Great video. Thanks.
Thank you Professor Dave!
I have learned. Thank You
not necessarily just 3 outbreaks. It is very possible that there was a similar plague that hit the Bronze Age at the beginning of the13th Centure BC ie 1300 to 1280, it devastated the Hittite Empire and perhaps set the stage for the downfall of all Eastern Mediterranean Bronze Age empires over the next 100 years
Well explained
Using this for my environmental hazards studying. Thank you.
This video was great!! With diagnosis and treatment it could have been perfect!!!
Interesting...Although i have to mention that in the distant past [before 1850] tuberculosis and the pnumeric were basically indistinguishable..They didn't know much back then.
May I ask some question, Professor?
As we known Yersinia pestis infected human via Rat flea, Is there has a case report about Yersinia plague infect cat? or cat cannot infected by Yersinia pestis?
I dont know, if you will respond, but I would like to ask if you could show me the source of the information about the bacteria, since I'm writing a project, and I'm kind of struggling to find information about how the bacteria is built.
Wow!!
That’s amazing
Thank you!!
5:00 Insects ARE animals
Decimating comes from the latin word for 10th and it means to destroy or kill one tenth of something, so the plague actually did technically decimate us
I think it means to reduce to only one tenth, no? So actually it almost literally did.
Wait actually I think you were right, so it was an understatement!
The new antibiotic resistant yersinia pestis in Madagascar enters the chat..
This should be required viewing for all science-denying types. Great video!
This aged like a fine white wine
@@thanoscube8573 I don't get it.
@@MisterItchy covid denyers
@@MisterItchy it wasn't a good joke
@@thanoscube8573 Oh yeah ... I didn't notice how long ago I posted that.
Excellent
Very educational
"Almost one quarter of all people alive". Well that puts it into perspective. I've never heard of plague in Australia.
Science fact: koalas actually eat and destroy the plague bacillus.
The first case of bubonic plague in Australia was reported in January 1900. But it is extremely rare in Australia, that's right. Wild rodent plague mostly exists in rural parts of the Americas, the former Soviet Union, Africa and Asia.
This sounds like the worst disease you could possibly get without immediate access to modern medical facilities
Ebola and rabies.
Corona without treatment is fatal, since plague is bacteria and corona is virus
@@ponalvsiki2254I had corona and did no treatment and that was 2 years ago and now I’m commenting to you so
I haven’t been this early since the black death
you missed the 17th century London plague
It's so sad one have to point out the necessity of science.
Need one asap
Wtf
@@indiagaming3618 Didn't get what i ordered. 1 star!!! LOL
Nerd pet peeve. The improper use of the word decimation. The word originally referenced the Roman legions form of punishment of killing every tenth man. So in actual terms the plague didn't "almost" decimate humanity. At least a couple of times it more than decimated humanity.
Beyond that, really enjoyed your show.
fun fact!
I've never been on this channel before and I'm two minutes in and I'm loving this guy lol I can't tell who the intended demographic is but I plan to stay
Wait, you just skipped the Great Plague of London that was in shakespear's time!
He only mentioned pandemics.
@@BPEREZRobertJamesL oooooohh.
Yes this is where ring a ring of roses a pocket full of poses atishoo atishoo we all fall down comes from. I couldn't watch all your video against hovind sorry Dave Hovind kept on saying strawberries 🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓🍓it was really annoying. But I'm giving you a big thumbs up 👍🤗😎🌏🌎🌍your Brilliant Dave thanks for educating myself. Keep up with the good work
Hold up ! Give the corona virus a chance
Dave sir actually here in India where I live we learn about
- Major events of history which took place in Europe
- Major events in China and south east ....
And obviously Indian
And it is compulsory for all students
@@ra_alf9467 accha
Omg! My name is Ersinia almost same in this plague. 😂🤣
PEST is your last name
Por favor al menos a sub español
Anyone here because of the coronavirus outbreak?
Still here
Coronavirus and black death are friends
Still here
@Joseph Joseph COVID-19, y'know, the thing that forced us to stay at home for 1 year.
I'm here because I smoked pot 🥸
The haircut looks a lot better.
Hypothetically speaking, if an antigenic shift occurred with covid-19 and yersinia pestis. How bad would it be or good?
It's always a trade off between deadliness and contagious. If it kills ppl off too fast, no host will remain well enough or alive to spread it. Covid is contagious but not super deadly.
A hybrid between both will probably look more like current covid
Good question i also want the answer
One is a virus and one is a bacterium...so..... nothing.
"Antigenic shift is the process by which two or more different strains of a virus, or strains of two or more different viruses, combine to form a new subtype having a mixture of the surface antigens of the two or more original strains."
Since the pestis is a bacterium I dare to say the chances are very slim to that happen.
@@Limpi43 glad you said "slim" because it's not impossible for a virus to rewrite a bacterial genome, granted covid is not a retrovirus, but it has already merged with other retrovirus types. Yes hypotheticals just being tossed out there.
1.99m :/
👍🏻
Cool
Good video, though I would say part of why the plague could spread like this included poverty. People die from the plague? Just give their blankets/clothes (unwashed and all) to families in need.
Antibiotic drenched blankets would only help...ok then.
💙💙💙
*NEEEEERRRRRRROOOO*
Plagues can decimate the human population; Yersinia Pestis hold my beer I can do 1 in 4 ! 😄
Scientists our first line of defence ...... scientists in Wuhan , our first line of defence..... scientists at Pfizer, Moderna, Oxford etc, our first line of defence...... get your memory checked!!!!
damn I'm glad you weren't my french teacher
666k subs bro
667 now, one day later.
Denis Daly jesus its 668k now
I am assuming that “The Black Plague “ was named as such because of where the vessel’s came from 🤯
buboes turn black and skin turns black
The Black Death came from the Black sea, yes.
Does this apply the same as the Corona Virus?
Could be if the virus mutates further
wrr
for me:
2:35
3:48
only the plague will dislike the video
A bible thumper disliked this video. Too much science not enough praying.
@@williamking951 Plus, the whole 666 thousand subscribers thing. This channel is the 👹
5:04 zoonotic infections are passed from an animal OR an insect? huh?
Ok, redundant, point taken.
@@ProfessorDaveExplains happens to everybody. nonetheless, great content as always!
What kind of drugs are you on
none at the moment
hey prof, time to clean up the mug rug bro . . . just letting ya know.
what's a mug rug?
He means your face, he wants you to shave.
Singapore is too clean it does not have any plague-
Hi boyfriend 🖐🏼
I blame one....
THANOS!!!!!
First!
apparently not
No sir, it started in Ukraine (Eurasian steppe). Not Central Africa....
You lost me when you said it was biblical
You deny that there are plagues in the Bible?
i came here watch parallel-world-pharmacy ep 9
