When Koch told his guess, everyone was dumbfounded.

The only one who was not surprised was John, after all, he had known about the hygienist's strange behavior. And he was not too worried about Petenkov's comfort, because after guessing the other party's thoughts, Koch would definitely give the other party his Vibrio cholerae that had been attenuated countless times, as in history. In this way, although the old man's body will inevitably be impacted, there is still no danger to his life in a short period of time.

However, John was even more determined to leave Hamburg as soon as possible.

Although he decided to come to Hamburg with Ehrlich to try to influence the cholera epidemic, John's original goal was achieved. His knowledge of infectious diseases was limited to the book of infectious diseases in his previous life, and all about cholera had been told to Koch and others. Next, John was not interested in continuing his research with Koch, Ehrlich and others, and certainly not interested in getting involved in the battle between Koch and Petenkov, knowing that a gentleman does not stand under a dangerous wall......

Well, the above is pure.

A gentleman or something, John was never one. In fact, he never forgot that this was the great age of colonization, and that one of the greatest enemies of the Europeans in the colonies of Southeast Asia, South Asia, and Africa was these ferocious infectious diseases, so the more infectious diseases developed, the more they were in these colonies. John came to Hamburg mostly psychologically, partly because of Anna and Ehrlich, and partly because of a doctor's sense of responsibility, otherwise he would have been hiding as far as he could......

Two days later.

Carrying a thick suitcase, John walked out the door. Behind him, Ehrlich followed, standing quietly beside the deserted street. Today was the day John left Hamburg, and Koch and the others were supposed to see him off, but the attempts to control cholera had just begun. The two of them were so busy that they could only say hello to John and say goodbye in advance.

In the Aurora parked at the door, a young man immediately got down.

Henry, who had rushed back to Hamburg from Berlin, hurriedly took the owner's luggage, put it in the car, and then stood respectfully and waited for John to get into the car. It's just that John turned his head and whispered to Ehrlich with a solemn face, "You...... Are you sure you don't want to leave with me? "Nope. I stay. “

Shaking his head, Ehrlich's voice was low and firm. As a native German and an expert in his field, Ehrlich took his choice to stay as a matter of course. And the reason why he followed John to Europe this time was because of Koch's invitation, and Ehrlich also hoped that he could stay with Koch and learn more.

John understood this too, and he was only one last confirmation.

After quietly glancing at Ehrlich, John sighed secretly in his heart, and then stepped forward to hug his right-hand man, patted him on the shoulder and whispered, "Remember." Every time you come back from going out, you must strictly disinfect it, the water must be boiled before drinking, the food must be fully cooked before eating, and there are ......"

In a few years, even a stone has become emotional.

Listening to John's admonition, Ehrlich's heart instantly swelled with warmth, but he smiled: "Don't worry, I will definitely protect myself." Hehe, I'm still waiting for the day when our school will become the best medical school in the world......"

……

The first half of 1892. There is an epidemic of cholera in the city of Hamburg.

The cholera epidemic will leave a very painful memory in the history of the city of Hamburg, with more than 8,000 people killed, tens of thousands of people becoming ill, hundreds of thousands of people fleeing their homes, and the city of Hamburg once an empty city. And in the course of the year. The controversy between Petenkov and Koch also became the focus of the European medical community, and the theory of bacterial pathogenesis and the theory of soil toxin volatile pathogenesis collided fiercely.

In the long run, of course, the bacteriological theory has triumphed, but in the short term, it is difficult to distinguish between the two.

In the original historical trajectory, in this polemic, Koch further refined his theories of infectious diseases, such as the Koch principle, and Petenkov took out the attenuated cholera bacillus that Koch specially prepared for him in one go. In the end, although he survived, his aging body withstood a great test, and left a "good story" for future generations of doctors to talk about in the history of medicine.

But in this life, everything has changed because of the appearance of one person.

John? Huntelaar, a German-American, came to London from New York to present his knowledge of cholera and a well-established theory of infectious diseases in the auditorium of the Royal Society. Although this theory is basically a continuation of Robert? Koch's system, but it is undoubtedly more complete and more precise, and at the same time it puts forward many concepts and systems that Koch did not touch, which naturally attracted very wide attention. Then, after successfully igniting the academic debate among British physicians, this Mr. Huntelaar came to Hamburg at great risk and bravely intervened in the war between Koch and Petenkov!

All the theories that were put forward in London are perfectly presented in Hamburg!

In May 1892, just a few days after arriving in Hamburg, with the assistance of Koch and Kitasato Shibazaburo and others, Johann? Huntelaar diagnosed and treated a group of patients infected with cholera. Rehydration therapy, which has a preliminary theoretical foundation, has officially become the key means of treating cholera patients from this day, and there has been no long exploration and attempt. Huntelaar directly gave accurate indications and dosages for oral and intravenous patches, and abandoned the traditional syringe injection to invent an intravenous infusion device that can control the flow rate!

The application of rehydration therapy was quickly and very successful.

Identifying effective treatments gave Koch a shot in the arm, especially when the collaborator was John? Huntelaar, a physician who was also of great repute in Europe, soon received a right from the Hamburg city government: the right to fully enforce strict prevention and control measures in some areas: to isolate the sick, disinfect water, remove garbage, eliminate flies, maintain public health, and of course, intensively prevent propaganda - boiling water, cooking food, disinfecting the home, etc., so that the incidence of cholera in the area under Koch's control dropped dramatically!

So even if Petenkov survived after drinking Vibrio cholerae, Koch's theory still succeeded!

Just a month later, the Hamburg city government made the decision to expand the Koch-controlled area, appointing a large number of physicians to study with Koch, Beili and Ehrlich, and purchasing a large number of sulfonamides from Heinz Pharmaceutical Company and intravenous infusion devices from Heinz Medical Devices.

In the meantime, John? Huntelaar left Hamburg and moved to Berlin after a few years of absence.
