Parasites Makes Us Dumber or Sexier

odie_q writes "It has long been known that the Toxoplasma gondii parasite alters its host's behavior, but now it seems the way it alters it depends on the sex of the host. From the article: 'A common parasite can increase a women's attractiveness to the opposite sex but also make men more stupid, an Australian researcher says ... Infected men have lower IQs, achieve a lower level of education and have shorter attention spans. They are also more likely to break rules and take risks, be more independent, more anti-social, suspicious, jealous and morose, and are deemed less attractive to women. On the other hand, infected women tend to be more outgoing, friendly, more promiscuous, and are considered more attractive to men compared with non-infected controls.'"

Your hand touches the couch, picks up some very small toxoplasmosis eggs; you sit there watching TV, eating popcorn, not having washed your hands. You've been pwned by the parasite. Worse, very worse, is that small children can get it by touching the cute kitty then sticking their fingers in their mouth. Cats are a big vector for this.

      I'm sure it makes great common sense to trust Wiki medical notes as always being absolutely correct, accurate, and true, since the Wikipedia has such rigorous tests for truth validity of submitted material.

      1) But aside from that, it's known that for two weeks after infection, cats CAN transmit the parasite in their feces and CAN carry the parasite externally on their fur through contamination with the feces. Hence there is a genuine risk period for physical touch. Now the problem is, when, ever, is that two week period? You can never know. Hence there is always a probability of risk from a cat. I repeat again, children are at risk from handling the animals, as they are far likelier to put fingers in their mouths. People are cautioned to avoid even breathing dust from cat boxes.

      2) I stand behind what I said about having the parasite's cysts in the brain being not generally a really great idea. a) parasite causes brain lesions. NOT healable. I don't care about post-infection treatment, that's locking the barn door after the horse is out. b) I've read a research paper saying the immune system can't effectively get to the parasite in the brain.

      3) the Wiki quotes use the weasel word "seems' quite a bit in regards to treatment. I think I'll stick to preferring 'certain' to 'seems to' when considering medical opinion.

      5) Research finds that the parasite alters behavior in mice, i.e. brain function, and makes me wonder considerably about effects in humans. If it affects aggression in males, and is estimated to affect 10 to 20% of people in North America alone... it's hardly insignificant to be concerned.

      Whaaa? Based on research, undercooked meat is the most common transmission vector for the disease. This isn't a guess, it's a fact. Also a fact: unless you handle cat feces, you have almost no chance of getting the disease from a cat. Let me quote this again: "Although the pathogen has been detected on the fur of cats, it has not been found in an infectious form, and direct infection from handling cats is generally believed to be very rare."

      This has been substantiated by research, testing the fur of infected cats for infectious material both in and out of the infectious stage of the disease. They have found no evidence that cats are infectious outside of their feces.

      So, yes, you are right: it is *possible* to get this disease through contact with cats (specifically through contact with their fecal matter). However, it is much more likely that a person would get the disease through a much more common activity: eating. Not only is undercooked meat a danger (anything under well done), but also potentially vegetables. Rodents, cats and other animals that rummage through a garden could contaminate the soil. If those vegetables aren't fully washed or cooked, it is possible to get it from your garden. Hell, you could get it even if you didn't clean yourself thoroughly after contact with infected soil.

      It all comes down to probability. There are *many* ways to contract this parasite. The most common way has nothing to do with cats. Cats themselves pose almost no risk if their litter is properly handled. Further, indoor cats have almost no chance of contracting the parasite due to a lack of infected prey. It is highly unlikely that you could ever really eliminate all possible causes of the disease, especially if you ever let others prepare your food (IOW: eat out at restaurants--cross-contamination in the kitchen is a bitch, read "Kitchen Confidential" if you don't believe me). Why would you get rid of cats when there are so many other risk factors that you can't eliminate? It is just senseless, or to use your words, invalid logic. If you really wanted to reduce your chances you would give up meat, never garden, wash and cook your produce, and never let others prepare your food. Are you really willing to make such sacrifices for a parasite that *might* effect your behavior but is still pretty treatable? Seems silly to me.

So what happens to a person when the immune system is weakened by a bad case of the flu or anything else? Do infected people see a flareup of the parasite, but never realize that is going on?

      You misunderstand the lifecycle of the parasite. Once past the infectious stage, sometimes the parasite goes into muscle and brain tissue and becomes a cyst. The immune system basically can do nothing about these cysts. The cysts then grow, caused by the parasite reproducing, then burst releasing tachyzoites into the blood and surrounding tissue. Left alone, these tachyzoites would become new cysts. However, the immune system attacks these tachyzoites, eliminating most of them before they can become cysts.

      Since the cysts are what is believed to cause altered behavior in mammals a weakened immune system wouldn't let the parasite effect our behavior more. If the timing were bad and a cyst popped when your immune system was down, it could cause more cysts to form. Ho

      That is an invalid model. The immune system does not function as effectively in all parts of the body. The question is how effective the immune system is in the brain. The blood-brain barrier prevents molecules from entering the brain that are injurious to neurons. This can include antiparasitic drugs as well as regular immune system components. The immune system chemical signalling system does not work as effectively because the brain protects against some of its components. Thus it is not reasonable to assume that the immune system can detect or attack tachyzoites within the brain. Indeed in AIDS patients apparently they are more likely to spread. I suspect that even in more commonly immune-weakened patients in the general population, for example having severe flu, that the parasite enjoys growth.

      Toxoplasmosis has only begun to be understood a little in the last five years. Researchers are finding out disquieting things about it that I believe show it is not the insignificant risk you believe, nor as treatable. Damage to the brain is not insignificant.

      To begin, a New York Times article of June 20, 2006 (archive access requires payment though) mentions "Researchers in Sweden report that the parasite fans out through the body by manipulating mobile cells that are part of the immune system. Toxoplasma hijacks these so-called dendritic cells and makes them race around the body and ignore commands from other immune cells to commit suicide. The dendritic cells sneak the parasites into the brain and other organs, acting much like a Trojan horse." I have not yet found publication source for the Swedish results but assume I will eventually.

      This shows the immune system is not as effective against the parasite as you maintain. 50 million Americans are estimated to have toxoplasmosis to one degree or another. There is hardly insignificant risk if the numbers are that large. Do all of them eat uncooked meat? I don't think so. Therefore the cat vector is worth more attention.

      It is clear you picked and chose results to support your conclusions. Because the AIDS study site you quoted contains conflicting results. The quoted,"Wallace found that Toxoplasma IgG antibody positivity did not correlate with cat ownership." becomes meaningless if the parasite disrupts normal immune function, which would hamper antibody formation. The parasite hiding within dendritic cells would block antibody formation. Hence lack of correlation with cat ownership is not proven. This is supported by results quoted in the same article:"Porter and Sande report that the absence of detectable anti-toxoplasma IgG antibodies does not exclude the diagnosis. In their retrospectively reviewed series, 4/18 patients with pathologically proved toxoplasmosis did not have detectable antitoxoplasma antibodies." So how many of the 4 got it from cat contact? Not shown. And Wallace not solid.

      You say "What this *does* show is that certain drug treatments have been successful in attacking brain cysts and significantly reducing their number" but that is not correct. There is a difference between certain drug treatments reducing parasites in the general body, leading to fewer spreading to the brain, versus combination drugs reducing the parasite directly in the brain. The Godolfsky results quotes are interesting, but are for one patient only, and the reported "cerebellar lesions had almost completely resolved by six weeks" is misleading since the brain does not repair lesions as such, the key is what is meant by resolved. Perhaps scar tissue. The paper does not support your extracted conclusion that the drugs combos attack brain-sited parasites, merely that they attack them in the body before spreading. And "decreased brain cyst burdens compared with no treatment" merely says that if you don't treat it, it spreads to the brain. It does not say the combined regimen acts within in the brain. I trust this distinction is clear? The AIDS site research all refers to maintainance therapy, which acts to kill parasites in the body leading to fewer getting to the brain, but does not describe therapy used to kill in the brain itself.

      It's an honor to be labeled 'smug' by someone who arrogantly labeled me a 'troll' in the earlier post that started this. Labeling is a time-tested way to improve the quality of one's arguments, I imagine.

      It would seem we share the same penchant for labeling. From a previous post of yours: "But hopefully the ones with the odd view might end up living longer and healthier than the smug ones." I don't think either of us have exactly taken the higher ground here, do you?

      To counter your arguments here, I'll use the very source you quote from, the New York Times Jun 20th article. From that article:

      An infection with Toxoplasma may feel like nothing more than a mild case of the flu, and the symptoms pass once the parasite has snuggled itself away in its cysts. In later years, cysts occasionally break open, but the immune system quickly destroys most of the free parasites. The few survivors invade new cells.

      This backs up my point about a healthy immune system effectively combating the latent form of the disease. Yes, in earlier stages, it spreads through hijacking immune cells. This does not appear to continue through the entire lifespan of the parasite.

      Also from the article: "It's perfectly safe to keep a cat," [Dr. Milton M. McAllister] said. "Just keep it inside."

      Which comes back to my original point. I've never tried to claim the disease wasn't insidious or not dangerous. In fact, I know of a first hand example of how bad it can be (a friend having contracted it and having it--or his immune system--attack his retinas). My only points are that: a) cat ownership is not dangerous and b) the disease is treatable (though not able to be eliminated). Incidentally, these are the only points you haven't provided evidence to counter (outside of claiming faulty logic and disagreeing with established research).

      May I also point out that you've done an awful lot of hand waving and trying to discredit my sources (don't trust wikis!!) and logic, but have provided precious little evidence to back up any of your points. This argument is a exercise in futility. Which is exactly why I called it un-winnable. You aren't forming arguments in good faith and neither of our positions have changed (the only possible way to "win"--and I use that term loosely--an argument).

      Finally, let me say how unbelievably creepy it is to have a complete stranger looking up info about you and using that in a random online argument. From your posts:

      Don't assume understanding of computer technology conveys authority in reasoning in a different field in which one has no background...

      My background (which is development for the financial industry--thanks for checking) has nothing to do with the topic at hand. Bringing it up in an attempt to discredit my logic and arguments is a very low form of debate. Grow up.

      I'm done. I only hope that others reading this thread (how likely is that, anyway?) will see the evidence I've posted and see the truth (as it is currently understood) about this strange parasite. Good day, sir. You can have the final word if you want it.

  27. Ahh Toxoplasma gondii by GrumpySimon · · Score: 5, Insightful

    I believe this is one of those news stories that sits around waiting for a slow news day. The original paper was released in November. It's written by Kevin Lafferty and was published in Proc. Roy. Soc. B.

    It's a really quite fascinating paper - I recommend tracking it down if you can get access. Here's how it goes: Toxoplasmia gondii is adapated to live in cats and reproduces in felid intestinal cells & is shed, encysted, in their feaces. Then it can directly infect cats who come into contact with the cysts, or it encysts in brains of smaller mammals, and moves up the food chain as they get eaten until it hits a cat, and can reproduce again.

    Fascinatingly, T.g. appears to affect rodent behavior to increase predation risk - i.e. the rodents become more active, less fearful of cat/cat smells, and have increased dopamine levels (which supposedly leads to novelty seeking behavior and neuroticism-type behaviors, or at least, they do in humans).

    Despite humans not having any major cat predators, it could still affect us as a byproduct type of thing. Particularly that whole dopamine increase - this is should increase neuroticism levels.

    So - the big question - does prevalence of T.g. correlate with cultural variation in neuroticism in humans? Lafferty finds a fairly strong correlation ( r2 of 0.38 ) between population aggregate neuroticism (as measured by the fairly standard NEO PI-R personality inventory ).

    Unfortunately I think the populations he uses for his stats are a little bit suspect (always the problem with worldwide analyses though), but it's definitely worth a read. You should also keep in mind that so far it's only an interesting correlation and not a direct demonstration that T.g. causes large scale cultural differences.

    Acute toxoplasmosis

    During acute toxoplasmosis, symptoms are often flu-like: swollen lymph nodes, or muscle aches and pains that last for a month or more. Rarely, a patient with a fully functioning immune system may develop eye damage from toxoplasmosis. Young children and immunocompromised patients, such as those with HIV/AIDS, those taking certain types of chemotherapy, or those who have recently received an organ transplant, may develop severe toxoplasmosis. This can cause damage to the brain or the eyes. Only a small percentage of infected newborns have serious eye or brain damage at birth.

    Treatment

    The vast majority of patients with a normal immune system require no treatment.

    Patients with HIV/AIDS or patients who are immunosuppressed should be given sulfadiazine and pyrimethamine. Pregnant women who become ill with acute toxoplasmosis should be treated with spiramycin. Folinic acid (leucovorin) is administered in all cases to reduce the bone marrow suppression caused by pyrimethamine (ref: Montoya JG, Liesenfeld O. Toxoplasmosis. Lancet. 2004 Jun 12;363(9425):1965-76. )

    Latent toxoplasmosis

    Most patients who become infected with Toxoplasma gondii and develop toxoplasmosis do not know it. In most non-immunodeficient patients, the infection enters a latent phase, during which only bradyzoites are present, forming cysts in nervous and muscle tissue. Most infants who are infected while in the womb have no symptoms at birth but may develop symptoms later in life.

    Treatment

    The cysts are immune to the standard acute treatments as the antibiotics do not reach the bradyzoites in sufficient concentration.

    The antibiotic atovaquone has been used to kill Toxoplasma cysts in situ in AIDS patients.[3] In mice, a combination of atovaquone with clindamycin seemed to optimally kill cysts.

    I so hoped that George W. Bush would win the 2004 elections to make sure he is still president when the failure of his presidency becomes more clear. So no one can blame the ongoing breakdown in Iraq and the reappearing Taliban in Afghanistan to a liberal and weak Democrat administration which messes anything up the Bush Administration has started.

    I was starting to wonder if the strategies of the Bush administration might just be based on complete incompetence and ignorance after them closing in on Iraq in connection to 9/11. I had a teacher who was in Iraq on a development project in the 1970ies with still some connections there, and according to her Iraq had a mainly agnostic government based on arabic-nationalist and socialist ideas (e.g. arabic nationalsocialism). Tariq Aziz, the former second man in Iraq, is a maronite christian, not a muslim after all. So all alleged connections to a fundamentalist muslim group were doubtfull at best. Saddam Hussein was trying to play the muslim card after the fall of the Berlin Wall and the demise of the Soviet Union, because Socialism was no longer fashionable, but with the Gulf War in 1992 the Muslim Card also failed because all neighboring states (both baathist/fascist like Syria and fundamentally islamic as Saudi Arabia and the Gulf Sheikdoms) were telling him off.

    In the end Saddam Hussein seemed to me just a dictator which tried to cling on power with all means, and I guess he was completely unideologic except for the ideology that he was not to be toppled.

    A big hint to the complete misinterpretation of the situation in Iraq was to me that the development of the war was so different from the predictions. The South, which was considered pro-intervention and expected to greet the U.S. troups with flowers and celebration, was fighting hard, and the Sunni Triangle, which was suspected to be strongly defended and determined for a last stand, was taken within the matter of days. When the toppling of Saddam's statue in Bagdad was mainly watched with lethargy by the people (compare the video footage with that of the Berlin Wall in 1989!) and only a U.S. tank managed to pull it down finally I knew: The invasion was utterly botched, and the Iraqi population was at best waiting how it would work out in the end. The plundering and looting in the following weeks might have finally tilted the balance against the U.S., and at this very moment I was sure that the cause of "bringing democracy to the Arab world" was lost.

    It just took two hundred thousands dead Iraqis, the Abu Guraib scandal, the Guantanamo disaster and another three years of ongoing insurgence in Iraq to let the U.S. electorate figure out the same thing. And the Bush administration seems only to have changed course to avoid a complete election catastrophe in November 2006. So this movement seems not to be not based in a thinking process within the administation, but just a tactic maneuver to stay in power.

Apparently, it is claimed that new research has confirmed this. This is of personal interest to me because my 14 year-old son was infected by Toxoplasmosis a couple years ago during a vist to Trinidad. Physicians suspect that the most likely source was my wife's aunt's home-made yogurt, which my kids love. My wife's aunt is an animal lover, and keeps numerous dogs and cats, as well as feeding hosts of wild birds that descend on the house every morning.

    If you replace "brought to justice" with "was executed very fast after only a single aspect of his dictatorship was slightly touched", then I agree.

    Yet commandeering someone to kill 148 people was surely already forbidden in the old iraqi law. Why not take the old laws and sentence Saddam Hussein according to them? Why artificially create new laws and enact them retroactively? If you want to prove that someone is bad and does illegal things, then start with looking at the laws in place when the suspected crime was done. He was a dictator after all, I am pretty sure that he didn't care if his actions were backed by a fresh law overriding the old ones.

    Getting the Shiites to cheer for Saddam Husseins execution was easy. They would also have cheered for him being executed for stealing candy. Getting the Sunnites to agree that he was a criminal is the hard part, and the way the process was done this chance was completely flundered. In the end Saddam Hussein was executed, but not brought to justice.

    I don't think it's "justice" if you create new laws afterwards and then tell people that they have run afoul of them. I know that this is very en vogue after 9/11, and suddenly "helping or being trained as a terrorist" is a criminal act, and it's up to the government to define case by case, what that means.

    What was until 2001 some kind of strange adventure vacation with some preaching, some training in a shooting range and lots of comraderie, completely has changed, and now you get indefinitely hold in detention without access to a lawyer, even though you might have been there decades ago and maybe even left soon after arrival because the camp looked too suspicious to you.

    What was an act of charity to some social organisations in the land of your roots, where you still have family ties now is "financing international terrorism" and also gets you in jail, even though you only wanted to help the creation of an elementary school in the village of your ancestors. And again it may be that it also puts you in jail retroactively for money you spend years ago.

    There's no basic services, and peace and self-sufficiency seem decades away. But there are some things that have been achieved. To the US taxpayer, or family member of those serving, it may not look like a victory. But for some people, the war is a massive success:

    -Increased military spending
    -Real life operations practice for US forces and test ground for new weapons technology
    -Re-building and resource extraction contracts handed out to US firms.

    As far as I see stopping Iraq selling oil for Euros (which Iraq only announced and never did) didn't help the U.S. dollar if you just look at the exchange ratios. From the heydays of 2002, when the Euro traded for about 0.90 US$ we have a steep decline to today's ~1.30 US$. The whole US economy was devalued 30% during the last five years. To offset that you would need a yearly gross economy growth of about 6%, but the US economy achieved a maximum of about 4%. Calculated in Euros the US economy shrunk 2% a year.

    Basicly what you are saying is that spending half a trillion of US$ a year to a very small part of the U.S. economy and the U.S. people is somehow a success.
