Chapter 168 Playing Games And Missing History
"It mainly measures three indicators, the lowest inhibitory concentration MIC and the lowest bactericidal concentration MBC, to see whether it has any effect on super bacteria." Professor Ma strategized, "I have already called the city hospital, and a batch will be sent out at about ten o'clock in the morning. Come over with Bowman, Verdigris, Kreb who are resistant to dozens of antibiotics.”
Song He looked shocked, "Send super bacteria here? Can our laboratory use this kind of thing?"
"The second laboratory can't do it, but the first laboratory can." Professor Ma said, "Students can't operate it, but professors can."
"Professor Tao, Professor Ji and I are responsible for it!" Lu Chengen agreed immediately.
"Is it safe?" Song He was a little scared. When he heard the super bacteria, he subconsciously clamped his crotch. He felt like he was transporting a bomb to the laboratory for disassembly. He was afraid that he would be blown up.
Professor Ma chuckled lightly, did not answer, and rolled his wheelchair to the first laboratory.
"It's safe." Professor Lu explained, "Ultrabacteria are generally only strong in the ICU environment. They are very vulnerable after leaving the ICU."
"Why?" Song He was startled.
"The drug-resistant genes in the super bacteria are huge. These genes are actually burdensome and reduce the survival ability of the super bacteria." Professor Lu was very patient.
"When exposed to the outside environment, super bacteria are killed by ordinary bacteria in minutes. Miscellaneous bacteria eat quickly in the natural environment and can absorb all the nutrients near the super bacteria, causing it to starve to death."
"The reproduction speed is also very different. Miscellaneous bacteria have been breeding for hundreds of generations, while super bacteria have just been living together for four generations, so they are completely uncompetitive."
Song He understood and was thoughtful.
So superbugs mainly threaten critically ill patients in the ICU?
Weak and severely ill patients are like natural petri dishes. Their immune system has collapsed, allowing superbugs to invade.
And other miscellaneous bacteria are eliminated by antibiotics, so the super bacteria loses its opponent and dominates the ICU!
"It sounds like the ICU is really a hellhole! Even half-dead people go in and have to face a bunch of super bacteria!" Song He frowned.
Professor Lu looked at his disciple with admiration, "Most of the superbugs are not very virulent, such as Bowman and drug-resistant Staphylococcus aureus. Patients will have thickened sputum and have a fever. Of course, there are also highly virulent ones, such as drug-resistant Staphylococcus aureus. If the finger is infected, it will eat through the palm of your hand in a day or two.”
"Although most superbugs are not highly toxic, seriously ill patients are already very angry!" Song He worried, "Maybe this is the last straw that breaks the camel's back."
"So new antibiotics are of great significance!" Professor Lu patted him on the shoulder.
"Superbugs occasionally occur in the natural environment, but don't worry, normal people's immunity can deal with it! If you don't have immunity, there will be people everywhere whose hands are bitten by drug-resistant Staphylococcus aureus."
After Professor Lu finished speaking, he hurried to the first laboratory and started working.
Song He's scalp was numb and he subconsciously looked at his hands.
I have to buy some immunity-boosting health products later. These precious hands of mine are priceless. If you withdraw, you can reward yourself. If you advance, you can promote human civilization. There is no room for loss!
More than ten minutes passed.
Graduate students and high school students arrived in the laboratory one after another.
The news that Song He discovered new antibiotic bacteria once again caused a sensation!
The way the high school students looked at Song He today was nothing short of awe!
They didn't even dare to get close to the River God for fear of disturbing him in his experiments. If the biological process was delayed, who could take the responsibility?
Unfortunately, Song He's petri dishes and culture bottles occupied most of the laboratory, so the high school students huddled pitifully at an experimental table in the corner, sitting neatly and reading, and occasionally looking up at the river god in the distance.
Zuo Gaoming came to work with dark circles under his eyes, stomping his feet in regret, "I knew I would stay with you all night last night!"
"Don't you sleep well?" Song He smiled.
"How wonderful is it to witness a historical moment!" Zuo Gaoming sighed repeatedly.
"In the future, when antibiotics are discussed in popular science textbooks on biology, they may mention that the famous biologist Song He and his assistant Zuo Gaoming discovered Song bacteria in the laboratory late at night!"
"I went to bed last night and my name was gone!"
As he talked, Zuo Gaoming felt regretful again and slapped his thigh to pieces!
Song He smiled. He thought to himself, Brother Zuo, you are worrying too much. The book can only write my name and not mention the assistant at all.
Many overlords in the world's academic world are assisted by assistants and students in their work, but after the results are produced, the credit goes to the overlords. The assistants and students are not even considered as backgrounds, they are completely empty.
"Don't be discouraged, I'm still looking for bacteria with antibiotic potential." Song He said, "Try to find another one, and you can witness history."
"How is that possible?" Zuo Gaoming was listless, either because he was depressed or because he hadn't slept well. "Bacteria with antibiotic potential are not Chinese cabbage. How can we find them casually?"
"You said the same thing before, but I found one last night." Song He said calmly.
"Ultra-low probability events cannot occur twice in a row. This is a matter of probability."
Zuo Gaoming had no confidence at all, but since Song He was still working, he had no choice but to serve the petri dishes.
The two of them worked together until ten o'clock.
Professor Lu and Professor Ji suddenly left in a hurry and came back a moment later carrying a metal suitcase, a box used by hospitals to contain expensive reagents.
After returning to the First Laboratory, Professor Lu rarely activated the door lock and locked the First Laboratory.
Song He's eyelids twitched, super bacteria are coming!
He temporarily put down his work and came to the glass wall to watch the professors work through the wall.
The process of measuring MIC and MBC is not complicated. Dilute the drug with liquid culture medium, add it to a 96-well plate, form a concentration gradient in different wells, add some experimental bacteria, and finally use a spectrophotometer to measure the OD600 value of each well.
The old-fashioned process requires a wait of one or two days, but the biology laboratory of Keihai University is quite capable. It relies on rapid machine readings and can get approximate results in a few minutes.
After a while, Lu Chengen suddenly walked to the glass wall, took out a piece of paper and wrote on it, and posted it on the wall for his lover to see.
[The MIC and MBC results are pretty good, and Song bacterium has the possibility of medicinal use! 】
[We will conduct an experiment on super bacteria immediately to see if we can kill super bacteria! 】
Song He nodded repeatedly, and Lu Chengen went back to work.
After a few minutes, it was obvious that the professors were sighing in unison, with disappointment in their eyes.
Lu Chengen came over again and wrote on white paper and pasted it on the wall.
[It has a weak inhibitory effect on Bowman and is completely ineffective on other ultra-bacteria]
[Antibiotics secreted by Songbacteria are of no value in fighting super bacteria]
Song He nodded without showing any emotion. This result was expected by him.
After all, the black technology blueprint also asked him to find another bacteria with antibiotic potential. If Song bacteria were used, the progress bar would have reached 40%.
Song He turned to leave, but Lu Chengen knocked on the glass anxiously.
The gray-haired Professor Lu, like a grandfather who was worried about his child being upset, quickly wrote a few lines on the white paper.
[Killing super bacteria has been a problem for decades, and it’s normal that it can’t be solved! 】
[It’s great to discover a new species of Song fungus! 】
Professor Lu gave a thumbs up and tapped the glass wall solemnly.
Song He smiled and nodded, indicating to the professor that he was not sad.
Return to the lab bench.
Song He continues to be busy, taking care of hundreds of newly made petri dishes, searching carefully with his eyes, like a gold digger looking for gold dust in a river.
Zuo Gaoming was a little passive. After finishing his work, he didn't bother to look at the petri dish and sat next to him playing with his mobile phone.
"Timi!" the mobile game opens.
Half an hour later, Zuo Gaoming knelt down several times and wanted to smash his cell phone in anger.
Song He suddenly said, "Brother Zuo, you will never forget these games you just played."
"Why? Did I lose too hard?" Zuo Gaoming was confused.
"Because you played these games, you missed the opportunity to find new antibiotic bacteria."
Song He said, reaching for a petri dish.
