Chapter 253: Bacteria Under the Microscope [Ask for a monthly pass, ask for a subscription]
Not only Shanhai City, but also the Americas, Europe, Africa, Oceania, and many countries and regions around the world are experiencing outbreaks of this new type of Legionnaires' disease.
This is a global catastrophe.
At this rate of transmission, the global community could collapse within a month if it is not effectively contained.
Even if they have their own minds, the governments of various countries can only stand together for the time being, and scientific researchers and medical personnel from all countries race against time together.
The first PCR results came out in Huaxia, Legionella pneumophila.
It was also first reported that erythromycin had no efficacy.
A new clue has just been given to the secret services of many countries, and the germ is artificially created and spread by humans: the Afterlife, the withered old man, and possibly the Lalleye Order......
The personnel of the Tianji Bureau are at the forefront. The state has also sent a number of ships to the waters near Shanhai City by sea, and the fleet has a complete range of scientific research equipment and scientific research teams, and helicopters transport samples and patients from Shanhai City to conduct various experiments on board.
If there is an epidemic in the fleet, all the people will not be evacuated.
From the moment they set out, they had only two outcomes, success, or death.
A batch of samples and patients have been transported out of Jiangxing Town, and everyone has not given up the fight on the front line of Jiangxing Town Hospital, the first line of the epidemic area.
There was a lot of noise outside, a mess in the small laboratory, new PCR amplification machines and other equipment resting on the lab table, and coughing kept ringing.
He Feng is no longer in isolation, as are his deputy Li Wen and other inspectors, but they are still wearing Level 3 protective clothing, not only to reduce their anxiety, but also to reduce the concentration of bacteria in the air. Although all of them are polluted and they are all infected, the CDC ethics cannot be lost.
Once they lose it, they are afraid that something will collapse in their hearts and they will never be able to pick it up again.
The culture of the bacteria made from the new blood sputum sample of the kingdom is placed in the small constant temperature incubator in the corner.
When they opened it before, He Feng and the others were all shocked, and Uncle Dan who came with them was also surprised.
It's not that they don't smell it because of the smell.
It was the glass disc petri dish that had formed a clump of colonies, round, grayish-white, moist and shiny, slightly raised.
This is precisely the colony characteristic of Legionella pneumophila.
"How long has this been cultivating?" Uncle Egg asked.
"About 34 hours." He Feng coughed and said, "I haven't changed the culture medium in the middle. ”
Looking at the medium in the petri dish that was almost exhausted, Uncle Dan was silent, this reproduction speed, fast, too fast.
There are four phases of microbial growth, retardation, logarithmic phase, stable phase, and decline phase.
The stable phase is also known as the maximum growth phase or the constant phase. In the words of the medical book: due to the consumption of nutrients in the medium and the accumulation of harmful metabolites, the reproduction rate of microorganisms in this period gradually decreases, the number of deaths slowly increases, and the number of bacterial cells that grow and divide and die is in a state of dynamic equilibrium.
It takes a process to get bacteria to this highest point.
But in front of us, it seems that the bacteria in the petri dish have entered a period of decline - the medium does not have enough nutrients, and the bacteria die more than they live. This speed is several times faster than that of ordinary intracellular parasites and ordinary Haemophilus legionella, and it is simply multiplying and growing at a rate visible to the naked eye.
And they die too slowly, and the colonies in the decay phase shouldn't be of this texture, unless they are filled with live bacteria in abundance.
So what do they consume? Are there really "harmful metabolites" for them?
He Feng's chills were even more intense, and it would have taken more than ten days of breeding to complete in one day.
This is why the patient's condition progresses so quickly. Now, every second, in the macrophages of the lung tissues of those who are infected, this new type of Legionella bacteria is multiplying wildly, eroding more lung areas and damaging various systems throughout the body.
Based on the new speed of development of the kingdom's disease, in another ten or so hours, he will be weak all over his body and gradually lose his mind.
For the sake of his daughter, He Feng hopes that he can struggle for a while longer.
Maybe it's the work of this period of time that has changed for a while.
With this in mind, the group quickly isolated the bacteria, put some of the colonies into another culture flask, sealed them, and handed them over to a task force to take away and transport to the fleet.
There are more equipment and drugs out there, and more bacterial antibiotic susceptibility tests, all kinds of tests can be done to look for the weakness of this bacteria.
Then they were busy again, taking the petri dish to the high-precision microscope that had also been brought in to observe the bacteria.
"What the hell ...... this thing," muttered Uncle Egg, "look what it looks like." ”
Uncle Dan leaned towards the eyepiece of the microscope, because he was wearing this airtight protective suit, this was really not an easy thing, and he finally saw some, Uncle Dan's heart tightened, and his spirit seemed to be affected and shook, a little panicked.
Under the microscope, Legionella bacteria is presented as an oblong shape, like a capsule-like thing.
But if you zoom in on the number, you can see that its surface is actually pitted, full of lumps of brain-like and intestine-like stuff crammed together.
It looked like a worm.
And now this new type of Legionella is still oblong, and there seem to be some obvious spots on the surface.
But magnification, magnification, and magnification......
The spots on its surface are all extended, like limbs, constantly kinking and wiggling.
It seems to have taken out all kinds of limbs from the limb warehouse of hell and spliced them together, and then magnified them, and I saw ...... The "palm" of each of its limbs has a hole like a mouth, and other tissues are wriggling in it......
Is this artificially made? Uncle Dan's heart is even heavier, he is really crazy.
"Ahem." He Feng then made an observation, which was the most bizarre and deformed bacteria he had ever seen in his years of disease control work.
At this time, the door of the small laboratory was pushed open, and a group of several young men in airtight protective suits walked in with guns.
The man at the head had a terrifying face, and He Feng and the others were stunned for a while, was it because of severe burns? It's not quite like ......
"Ah Jun!" Uncle Dan suddenly snorted, as if he had just found the backbone, and his fighting spirit was a little higher, "You come to see this thing." ”
He Feng thought about coming over, Gu Jun, Doctor Gu! I have explained it before, Dr. Gu is a hero in that secret department.
"Doctor Gu!" He Feng couldn't help but exclaim, tears almost welled up, save us, save my daughter......
From the moment Gu Jun walked into this laboratory, he had a sense of illusion, he nodded to everyone and said hello, and strode towards the microscope.
