John was very hesitant to come up with knowledge that could facilitate research on infectious diseases such as malaria.

In this era, except for the United States, malaria is still relatively rare in Europe, but for most tropical countries, malaria is a very serious disease...... This means that for the British and French, the danger of malaria is very staggering, because their colonies are arguably the largest. So in a sense, promoting the research of infectious diseases in the Western powers is also a bit of an abusive one.

Of course, he knows how much impact what he is going to talk about today will have on bacteriology and infectious diseases!

For example, cholera and malaria, which will be discussed next, will have a significant impact on the study of these two infectious diseases, especially the ongoing cholera outbreak in Hamburg. Of course, all of this is premised on other people being able to accept their own theories and results......

However, this entanglement only existed for a few minutes, and John left it behind.

Didn't the great powers get the benefits, but the natives of the colonies didn't? After all, they are the ones who die the most, no matter what time it is. And for John himself, the benefits of this were obvious – the study of infectious diseases at the end of the 19th century was a great way to gain prestige! So although John was not interested in mixing it up before, he also handed over some corresponding theories to the professor of bacteriology at the medical school, hoping that they would use these results to give the school prestige, but the plan could not catch up with the changes, and John completely ignored the cholera epidemic in Hamburg.

So after deciding to go to Hamburg with Ehrlich, John decided to take some of these things out.

“…… Now that we're done talking about malaria, let's talk about cholera. ”

I took a sip of water and waited for the commotion in the audience to subside a little. John then exclaimed: "Everyone must know the dangers of cholera, and now there is a serious outbreak in Hamburg across the Channel. Cholera has long been known as miasma, for example, at the International Health Conference in 1874, when 21 governments voted unanimously that 'the bad stuff that causes cholera is still flying in the air', and for nearly two decades to come. Even if cholera is raging on the European continent, even if Vibrio cholerae has been discovered, even if bacteriology has developed rapidly, the theory of bacteria has not been included in the international health conferences on cholera transmission in successive times...... Hehe, this cruel fact only proves an old saying: the truth may be on the side of the few! ”

"Buzz ......"

When I heard this, there was a stir in the audience.

It's just that this kind of agitation seems to have become accustomed in this auditorium this morning, especially what Huntelaar just said about transmission routes, prevention and control measures, etc. Leave everyone stunned. Except for a very small number of physicists, all of them are physicians, so they can naturally hear that the other party is not talking nonsense, this theoretical system is obviously very mature, and it is obviously not comparable to those theories that rely on the results of primitive epidemiological investigations to speculate!

But......

Even so, is there nothing wrong with such a ridiculing conclusion of European countries?

Of course there is no problem!

John, who was well aware of the development of infectious disease research in Europe in the next ten years, took a deep breath and then said loudly: "Gentlemen, most people know that it was Mr. Koch who discovered Vibrio cholerae. But what I don't think you know is that it was back a few decades. An Italian Mr. Pacini had already discovered this little thing, but alas, bacteriology was just beginning at that time, and the priest-turned-Mr. Pacini could not convince the rest of the scientific elite! ”

Pasini? Italian?

After hearing this name, many doctors in the audience frowned slightly. The name is too unfamiliar to them, and in fact most people only know Robert? Koch discovered Vibrio cholerae a decade ago. But until now, whether cholera was caused by this strange bacterium or not has remained a matter of debate – the infectious disease theories and medical techniques of the era have not yet been able to determine this.

Then the question arises, how is this guy on stage so sure?

"Gentlemen. What I know for sure is that cholera is a virulent infectious disease caused by the bacterium Vibrio cholerae! ”

As if guessing what everyone in the audience was thinking, John opened his mouth without hesitation and sneered: "In this regard, I stand unconditionally with Robert? On Professor Koch's side, and before Professor Koch, Monsieur Pasteur of France also speculated on the relationship between cholera and germs, and completed a series of experiments that could be called great......"

"However, this still does not prove that Vibrio cholerae is the culprit!"

When he heard this, the doctor in his thirties in the audience finally couldn't help but shout. It was clear that he was a staunch supporter of the miasma theory, so it was a little upset to hear John say that it was bacteria that caused cholera, and he had good reason: "Mr. Huntelaar, do you know Mr. Petenkov?" He thought it was a toxin in the soil that caused cholera, and it was the evaporation that caused people to get sick......"

Petenkov?

After hearing this name, John was slightly stunned at first, and then his face quickly darkened!

The name Petenkov is also a famous name in the history of medicine, but John knows that his reason is not a famous medical theory, but his spirit of "dedication to medicine" like many medical scientists. In history, this bull man and Robert? Koch was a sworn enemy because one of them was the inventor of Vibrio cholerae (later changed to Italian) and insisted that Vibrio cholerae was the cause of the disease, while the other believed that people got cholera because of a cholera toxin in the soil that volatilized to make people sick. The academic rivalry between the two lasted for several years, and in order to refute Koch's theory and prove that cholera was not necessarily caused by Vibrio cholerae, this Mr. Petenkov actually asked Koch to prepare some Vibrio cholerae for him, and then dried the cup of Vibrio cholerae in front of the others!

And......

"That guy has to drink Vibrio cholerae like a drink, it seems like this year, right?"

After searching his memories, John soon found an account of Mr. Petenkov. It has been ten years since Vibrio cholerae was found by Koch, but the battle between bacteriology and miasma theory has also reached its peak, for example, this Mr. Petenkov, his so-called soil toxin volatilization theory, is actually a variant of the miasma theory, but even if he holds this theory, because the residual power of the miasma theory still exists, he is now known as the "rightful authority on cholera disease", and the meaning of survival seems to be fighting against Koch!

John never meant to despise such people.

Every era has its own limitations, and John cannot blame a late 19th-century physician for his mistakes, even if his mistakes are enough to be heard as anecdotes and jokes a hundred years later. But again, it is difficult for him to have enough respect for such scientists, just as he did for Koch, Pasteur and Liszt.

So after a moment of silence, John said aloud: "First of all, I want to emphasize again that I will not answer any questions until the end of today's report, so this gentleman ...... But this time is an exception, and I can explain it to you, because in the next period of time, I will explain to you, in detail, my research on Vibrio cholerae, the source and transmission of cholera, the typical clinical manifestations and laboratory results of cholera patients, and of course, more importantly, the ...... of effective treatment" (to be continued). )
