I thought it would be difficult to enter the laboratory, but I didn't expect Li Bai to agree very happily.

"Yes, I happen to have a project in progress, usually I have to go to the site during the day, I don't have time to do it, and I often catch up in the laboratory at night, you can go in with me. ”

With Li Bai's consent, Lin Xiaoxiao stayed alone to observe the experiment.

After reading catching fleas for mice, I looked at the sample and took nucleic acid, and waited for the results on the machine.

By the time the endemic typhus detection experiment was over, it was already past 10 o'clock in the evening.

Lin Xiaoxiao found Li Bai's laboratory from this laboratory, and he was still busy inside.

On the glass door of the laboratory are a few large words "Sequencing Center" and the logo of the Yunhai Center for Disease Control and Prevention.

"Director Li, what are you doing? Do you want me to help......? I want to learn, to be exact. Lin Xiaoxiao stood at the door of the laboratory and asked.

Li Bai glanced at the time, "I'm doing sequencing, today's work is basically over, if you want to learn, I'll bring you over next time." ”

Li Bai tidied up the laboratory and walked out of the experimental building with Lin Xiaoxiao.

Lin Xiaoxiao hurriedly ran to the bus stop at the door.

Li Bai called out to her, "It's too late, I'll send you back to school." ”

Lin Xiaoxiao waved his hand as she ran, "No need, there is still the last bus, it is convenient for me to take the bus." ”

Looking at Lin Xiaoxiao's back, Li Bai was not at ease, drove her out of the CDC compound, watched her get on the bus from a distance, and then drove the bus to the gate of Yunhai University.

——

Early in the morning of the second day.

Lin Xiaoxiao arrived at the emergency office half an hour early.

Li Bai arrived earlier.

"Director Li, the results of yesterday's experiment are out, right?"

The results of the experiment should have come out at ten o'clock last night.

The laboratory will not tell Lin Xiaoxiao the results, but will give feedback to Li Bai in time.

"Well, it has come out, the second batch of patients have detected corresponding antibodies in their serum, proving that they are infected with Rickettsia Moschi, and the nucleic acid of Rickettsia Mochii was detected in the peanuts and sesame seeds at the breakfast stall of Chen Kee Grocery Store, and the flea nucleic acid found in Aunt Li's cat was negative. ”

Lin Xiaoxiao felt a little excited, it seems that yesterday's speculation was correct, Aunt Li was indeed infected because she ate the contaminated breakfast at Chen Kee's grocery store.

Hearing the results of the experiment, Lin Xiaoxiao was full of enthusiasm, and the sticky mouse board arranged yesterday caught a total of more than a dozen mice, and he gained a lot.

In the following two days, a large-scale chemical and physical rodent eradication operation was carried out in cooperation with the sub-district to the entire urban village.

——

A few days later.

Yunhai Center for Disease Control and Prevention, Emergency Office.

Li Bai is writing a summary report on the epidemic.

Xingfu Sixth Village, Lianyun District, Yunhai City, is an urban village with dirty and poor sanitary conditions.

Rats were rampant in the village, carrying Rickettsia Mossi in their bodies, and infected Chen Jiaming, the owner of Chan Kee Grocery Store, and his wife through rat flea bites.

The peanuts and white sesame seeds at the breakfast stall of Chen Kee Grocery Store were contaminated with the feces and urine of rats infected with Rickettsial Mossi soil, and Aunt Li and some customers who had eaten breakfast were infected.

Six other villagers and tenants in the urban village were bitten by rat fleas and contracted with Rickettsia mocheli, showing symptoms of endemic typhus.

After rodent and flea eradication, the transmission route was cut off and the epidemic was controlled.

After treatment, the infected people were discharged from the hospital one after another, with no deaths and no serious sequelae.

——

After the epidemic ended, Lin Xiaoxiao finally had time to discuss this matter with Angel Xiaobai on the Internet.

Xiao Linzi: "Xiaobai, there is an outbreak of endemic typhus cluster cases in Yunhai City, do you know about this?"

Angel Xiaobai: "I know, all the official accounts of disease control and control are pushing this news, and the epidemic has been introduced very little, and most of them are popular science news on how to prevent this disease." ”

Kobayashi: "I have been involved in handling this epidemic. ”

Lin Xiaoxiao's voiceover - come and praise me.

Sure enough, Angel Xiaobai sent an admiring expression, "It's been a long time since I sent you a love letter, the 5th letter, receive." ”

Accept, click, it's still the same as before.

Endemic typhus: small fleas, so cute, bouncing, biting, spreading diseases, the most proficient.

AIDS: Typhoid fever has been heard, endemic typhus has not been heard.

Typhoid fever: My pathogen is typhoid bacillus, which has nothing to do with endemic typhus.

Endemic typhus: My pathogen is Rickettsia Moschi.

Epidemic typhus: My pathogen is Rickettsia przewalskii.

AIDS: It's complicated, it's confused by your names.

Endemic typhus reverts to AIDS: Actually, we all have similar symptoms, but the pathogens are different. I and epidemic typhus belong to rickettsial disease.

Scrub typhus: I also have a rickettsial disease.

Cat's claw disease: Rickettsial disease +1

Q fever: rickettsial disease +1

Heilongjiang tick-borne spotted fever: +1

North Asian tick-borne spotted fever: +1

Inner Mongolia tick-borne spotted fever: +1

Human granulocytic anaplasmosis: +1

Human monocytic ehrlichiosis: +1

AIDS: OH! MY GOD...... Queue up to brush up on the sense of existence, there are many members of the rickettsial disease family, but I want to read Xiaodi's autobiography.

Endemic typhus: Here is my autobiography.

I am endemic typhus.

I spread it through rat fleas, so it is also called rat typhus and flea-borne typhus.

My pathogen is Rickettsia Mozeri and my nickname: Little Mo.

Xiao Mo belongs to the order Rickettsia, Rickettsia, Rickettsia, typhus.

Xiao Mo usually lives in the body of rat fleas.

The rat flea lives on the rats.

When the rat flea leaves the rat and goes to other animals and bites other hosts, it will infect Xiao Mo to the new host.

Mo can also be transmitted through the host's feces and urine.

Therefore, when the feces and urine of infected rats contaminate food and the environment, other animals can also become infected if they eat the contaminated food or come into contact with the contaminated environment.

Xiao Mo infects humans, and the disease that humans suffer from is me - endemic typhus.

After humans are infected, Xiao Mo will now reproduce locally.

It then enters the bloodstream, producing rickettsial emia.

Then it reaches the organs and tissues of the body, and toxemia appears.

Corresponding pathological changes occur in human tissues, mainly cardiovascular inflammation.

In humans, high fever, headache, rash, hepatosplenomegaly, gastrointestinal bleeding, pneumonia, ...... and other symptoms.

Although my symptoms seem ferocious, my lethality is low.

A lot of antibiotics can kill my pathogen, Xiao Mo.

doxycycline, macrolide antibiotics......

Antibiotics, make me shiver.

AIDS: Wow, endemic typhus is also afraid of antibiotics.

Endemic typhus: Are there bacteria that are not afraid of antibiotics?

Typhoid fever reverts to endemic typhus: Are you a germ?

Endemic typhus reverts to typhoid fever: Broadly speaking, rickettsial is also a member of the large family of bacteria.

Clostridium difficile: I've made it through the antibiotic maze and evolved into a superbug.

Endemic typhus reverts to Clostridium difficile: You're an example.

Clostridium difficile returns to endemic typhus: If humans use too many antibiotics, we all have the potential to become superbugs.

❤❤❤❤❤❤

Xiao Linzi: "This kind of love letter is really special, I like it very much, how long do you plan to write it?"

Angel Xiaobai: "Keep writing until there is no more disease and pain in the world, or you don't want to watch it anymore." ”

Xiao Linzi: "Oh, that's forever. ”
