Chapter 806: parasitic? Symbiosis?

Chapter 806: Parasitic? Symbiosis? "... Yesterday, the United Nations convened an ad hoc meeting in New York to determine the emergency response to the global crisis of Martian invasion. A research team composed of researchers from multiple countries will be stationed on the Lunar Palace space station within a week to jointly Research on this strain. "
"At the same time, according to the research decision of the World Health Organization, the bacteria was officially named X-0172 bacteria."
"Hua Guo News, report for you."
Reports on Martian bacteria are over, and news on TV continues to show.
Sitting at the table and enjoying breakfast quietly, Lu Zhou glanced at the calendar on his phone and said to himself.
"There are 87 days left."
Time is tight ...
I took the remote control and turned off the TV. Lu Zhou took out a paper towel and wiped his mouth, then pushed away the chair and stood up from the table.
小 "Xiao Ai, it will bother you to clean the tableware."
A quad-rotor drone flying a small TV flew over the kitchen staggeringly.
[Good master, leave it to me! 】
After Xun tossed Xiao Ai to clean up the table, Lu Zhou took a coat from the door and put it on his body, and then called Wang Peng.
A black red flag stopped outside the villa soon, and sent him to the Jinling Advanced Institute from his doorstep.
In fact, in a strict sense, research in the biological field is not the strength of Jinling Institute of Advanced Studies.
Especially the up-and-coming branch of the up-and-coming astrobiology, let alone the Jinling Institute of Advanced Studies, who couldn't find a person studying this direction, even if they were placed in the top five national universities in China, they could not find many.
However, sometimes research involving frontier fields does not necessarily have to be done by a professional counterpart. After all, the more cutting-edge things, even professional counterparts, are at least a little more experienced, and everyone's starting line is actually similar.
At present, the Institute of Advanced Studies is considered to be the best in the field of microbiology, and only Professor Liu Zuobing is in charge of the "frozen dormancy" project.
Although his main research direction is cryobiology, because he often studies cell samples collected in extreme environments, in a sense, he has more say for X-0172 bacteria.
After all, X-0172 bacteria are also collected from extreme environments ...
After getting off the bus, Lu Zhou went straight to the building of the Institute of Biology.
他 When he arrived at the laboratory, Professor Liu Zuobing and several of his students were busy observing and recording something in front of the electron microscope.
I did not disturb their research. After quietly waiting for them to finish their work, Lu Zhou stepped forward and looked at Professor Liu and asked.
"Has the sample been delivered?"
"Has been delivered," pointing to the slide specimen placed on the microscope. Professor Liu Zuobing joked and said, "I bet this is probably the most expensive feces in the world."
Lu Zhou also joked and said.
"... probably also the most dangerous in the world."
Professor Liu Zuobing smiled and said, "Don't worry about it. The specimens sent to the earth have been inactivated to the highest level. As long as they are operated strictly in accordance with the provisions of the safety manual, there will be basically no problems."
Although a little sensitive to the word "basic", Lu Zhou still believes that Professor Liu's level should not make such low-level mistakes.
After Xu paused for a moment, Lu Zhou asked what he was most concerned about.
"Has research progressed?"
"There is a little progress," Professor Liu Zuobing pushed down his glasses and continued. "According to the latest research published by Professor Leslie and Professor Zhao Shuxuan, we can confirm that the sleepiness symptoms of Ares plan colonists. "It should be caused by the amino acid-like derivatives secreted by X-0172 bacteria during spore formation."
"Amino acid-like derivatives?" Lu Zhou frowned, and continued to ask, "Is the problem serious?"
"Serious to not serious. This kind of amino acid derivative is very interesting. It will not only harm the host, even ... it will be beneficial to the host."
Lu Luzhou: "... beneficial? Can you elaborate with me?"
"Active dormancy," suddenly thrown out a word unexpected by Lu Zhou, Professor Liu explained in an inferred tone, "assuming that Mars once had the atmosphere, magnetic field, and even a variety of ecosystems, when encountering severe geological When changes in Mars or other external factors cause Mars to become less livable, the pheromone released by this bacterium when producing spores will likely help the host through the period of lack of supplies, just like hibernation. "
Helping the host through the extremely bad weather, on the surface, it is helping the host through the difficulties, and in fact it is the self-rescue of the bacteria. Therefore, compared with the parasitic relationship, the bacteria and the host are more like a mutually beneficial symbiotic relationship.
After talking about this, Professor Liu Zuobing paused for a few seconds, looking at the thoughtful Lu Zhou, and continued.
"At this time, we have not found that in addition to drowsiness symptoms, this bacterium will have other effects on the health of the host. We have reasons to believe that secretion of pheromone belongs to an active defense mechanism of the bacterium. The form helps the host actively dormant ~ EbookFREE.me ~ Under this dormant state, the host's tolerance to extreme environments will be greatly improved, and only a small amount of energy will be consumed to ensure the minimum life characteristics . "
Lu Zhou thought for a moment and then asked, "But what about the mechanism of releasing pheromones?"
"The problem is here, we haven't fully figured out its mechanism for the time being," Professor Liu Zuobing sighed. "There are currently two kinds of speculations. One is when the host itself has an immune response to foreign bacteria. Under the attack, the bacterium was forced to produce spores for its own protection, and the active dormant pheromone was forced to be released. "
"As for one possibility, under the stimulation of certain external physical conditions, the bacteria may determine that the host is in an extremely harsh environment and actively release spores and dormant pheromones to protect the host."
Although drowsiness is not a fatal symptom, if you doze off all day long, it is also a headache for a normal person.
At present, one of the three colonists has found a similar situation, which means that the probability is at least one-third.
If one third of the people on the planet double their sleep time every day, it is hard to say what kind of impact it will have on modern society.
Lu Zhou pondered for a moment and asked, "Which one do you prefer?"
教授 Prof. Liu Zuobing: "I prefer the first one."
Lu Lu immediately responded: "That is, there may be antibodies to X-0172 bacteria in the colonist who has clinical symptoms of drowsiness?"
Professor Liu Zuobing nodded cautiously.
"It's hard to say, but I think it should be like this!"
