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.
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.
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
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
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.
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?
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.
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.
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
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.
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.

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
"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.
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.
No, the coronavirus is airborne-transmitted, this means it spreads through air like the influenza. Yersinia pestis is also a bacterial plague, and unlike the coronaviruses, they are a viral pandemic.

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!

Great info, Professor. Thank you for uploading for the rest of us to learn from.

Using this for my environmental hazards studying. Thank you.
Great Sir your videos help us in every step of microbiology
This video was great!! With diagnosis and treatment it could have been perfect!!!
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

Thanks prof. I wish you all the lucks.
"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.

you missed the 17th century London plague
Thank you Professor Dave!

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.

Omg! My name is Ersinia almost same in this plague. 😂🤣
PEST is your last name
Excellent

Antibiotic drenched blankets would only help...ok then.
only the plague will dislike the video
A bible thumper disliked this video. Too much science not enough praying.

Plagues can decimate the human population; Yersinia Pestis hold my beer I can do 1 in 4 ! 😄

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.
damn I'm glad you weren't my french teacher
Does this apply the same as the Corona Virus?
Could be if the virus mutates further
No, the coronavirus is airborne-transmitted, this means it spreads through air like the influenza. Yersinia pestis is also a bacterial plague, and unlike the coronaviruses, they are a viral pandemic.

Singapore is too clean it does not have any plague-

No sir, it started in Ukraine (Eurasian steppe). Not Central Africa....
