such as still inthe womb

You heard Toxoplasma gondii? Estimates didn't. For a parasite,not be found by host is the biggest win. From this perspective, toxoplasmagondii is one of the world's most successful human parasites, because more thanhalf of people are its host in the world.
Cats can change a person's character. This change is notbecause the cat very cute, it's also not because cats can cultivate people'sresponsibility, but because the cat will put a parasites name of toxoplasmagondii infect master.
Unless the host immune system is too weak to (such as still inthe womb, or the baby by some) damages (such as AIDS), otherwise will onlytoxoplasma gondii in early stage of infection, triggered a slight cold afterthey no longer attack, so most people won't find themselves has come back.
So, since toxoplasma could infect 30 billion people in theworld, is it not of that most people's thoughts by cat influence? Return truesomeone did the research. August 1, at the university of California Santa Barbara scientists Kevin Ralph mentionpublished a research report, claiming toxoplasma can affect human and culturalchanges. The author of different nationalities statistics toxoplasma gondiiinfections, and some of the character of the national compare rates and foundtoxoplasma gondii is most likely to get the national high neurotic"". Of course, his study also very primitive, still need more data.However, there are many nationalities have similar sayings. Don't believe it?You can raise a cat to have a try.
Actually toxoplasma gondii is one kind of single-celled microbes,size is very small. Its life need two host, the most important host is a cat.It in the cat's intestines ######ual reproduction, once only, can produce hundredsof millions of eggs. These eggs with droppings, can survive a year in the soil.If people eat vegetables that don’t carefully wash will infect. Not only that,the majority of thermostatic animals can be infected, they are the second host fortoxoplasma gondii. So if person eat the boiled meat, it will easy to beinfected.
Mice and men are in mammals, since toxoplasma can change thebehavior of mice, why can't change people's behaviour? This reasoning seemsquite reasonable. In fact, the bacteria or virus infection can really changethe behavior of people’, scientists have accumulated many examples in. Forexample, chronic infections can let the immune system to keep long excited and itwill lead to a blood Serotonincontent decrease. The medical profession knew,serotonin content low can directly lead to depression, and that is why longillness can let a patient moody, depressed the important reasons.
In fact, toxoplasma itself is very weak, cannot resist theimmune system attacks the positive. But they once under attack and will be aplunge into human body cell teachings in the membrane of the cell membrane, letthem in, so that they escaped the immune system's patrol. Toxoplasma gondii cansurvive in this dormant for many years and not be found, so once people infectedtoxoplasma gondii cured thoroughly, it's very hard.
Toxoplasma once enter human body, will spread rapidly throughsystemic, especially like gathered in the brain. Scientists have looked atunder a microscope infected blood, results only found in very small amounts offree activities toxoplasma, and they are special honesty, swimming is slow. Sohow they are transmitted? Scientists haven't understood.
Swedish scientists at decided to look into the problem. Hefound toxoplasma like invasion of dendritic cells, this is a kind of immunecells air jordan 7 high heels red black white , responsible for identifying foreign pathogens. Barak Kennedy found thatdendritic cells once toxoplasma stick on, will become super active buy nike heels , like idiotunder a microscope rampage. He guessed that perhaps dendritic cells weretoxoplasma kidnapped? To prove this conjecture, he put a can produce the genesfluorescent substance toxoplasma gondii in secret, so they could toxoplasmaactivity observed. This exquisite experiment has proved that the suspect, barakKennedy toxoplasma like hiding in the Trojan horse, and hide in the warriorthat dendritic cells inside, not only so and ran so fast, but also escaped thehuman immune system in surveillance.
But the story in recent years has been received challenge, scientistsfound that the host toxoplasma can change the personality! This wonderfulcharacteristic is first discovery in mice. In 2000, scientists at theuniversity of Oxford, UK, published the study confirmed infection of thetoxoplasma gondii mice get no longer timid, usually can't go to the place alsodare to, even the cat also not afraid. This year, Stanford universityscientists further find that toxoplasma not only can let rat"problem", losing timid and will let the mouse form a new disorder -like to smell the cat urine taste! Results it is conceivable that the mice aremore likely to be cat ate. A cat all know, cats don't like to eat dead animals.Toxoplasma want to quickly enter the cat's body, finish her life cycle, notonly should not kill them bodybuilding corset , and the mouse must be quickly let cats catch.
