If parasites control the actions of animals they infect, how might humans be similarly effected?

Certain strains of Candida infect the digestive systems of humans supposedly creating an urge for the host to consume large quantities of sugars and other simple carbs.\nReadily available food for the yeasts.\nOh yes another example...some parasites (worms) make your butt itchy,  you scratch your butt then you have eggs on your fingers which can then infect another person this helps the parasite pass to another host.  WASH YOUR HANDS!  AND DONT SCRATCH YOUR BUTT!

like others have said parasites are definately living things.  I didn't know there was even a debate as to whether virus are living things, I thought it was pretty much agreed upon that they are.  I guess it depends on your definition of life, which is something that's a hotly debated issue.  I don't think there is a clear cut answer myself as far as what should be considered a life form and what shouldn't.

Animals cannot get the same stds that people get.  Human STDs are specific to us - that includes crabs.  Crabs evolved to hold onto human hair - not fur, which has a different structure.  Things like human herpes, HPV, syphillis, etc. also have evolved to affect only human hosts.  \n\nThere are STDs that affect animals though.  They cannot transmit them to us and we cannot transmit our to them.  \n\nEven plants have diseases that are tranmitted through pollenation - which is one form of plant sexuality!\n\nAnimals can transmit Hepatitis A, salmonella and other infectious diseases - but they are not considered stds.\n\nAnimals cannot get HIV because that is HUMAN immunodeficiency virus.  Some animals (like cats, monkeys, apes, and others) do have immunodeficency viruses, but they are not transmittable to us and we can't get theirs.\n\nAlthough some animals share about 90-95% of the same genes as we do - that 10 to 5% is still a huge amount of genes that we don't share.

definitely humans, no other species is known to cause so many other species go extinct or near extinct and change so large areas to worse. \n\nsome people say that human influence is natural influence because man is part of nature. than we have to face the fact that we are a perfect natural DISASTER, just like a masssive asteroid on collision course

Millions of people are infected by the parasites worms worldwide. Parasites can enter our bodies through food, water, mosquito bites, or through the nose and skin. More than 100 types of parasites worms can be living happily in human bodies. Some are big in size that can be seen by eyes, while the others are microscopic in size. Only about 5 percent of these varieties can be tested positively with only 20 percent accuracy. \n\nParasites worms find a perfectly living environment when the bowel becomes ineffective in the elimination of the waste products due to constipation. \n\nParasites may be categorized into four types: Protozoa, Trematoda, Cestoda, and Nematoda. Nematodes include common roundworm, hookworm, whipworm, pinworm, heart worm, etc.

They dont, birds do. Humans can not catch a virus from birds tho, so there has to be a middleman (well pig). Birds give the virus to hogs, who then with a little twist of the virus give it to humans (hence the first name of swine flew). The best place for this to happen is a place that has both foul & pigs (a farm) so that is why you always hear about chickens & ducks (but it can be any bird).

Some viruses are not specific to animals or to humans and can be passed back and forth.  For example, the avian flu.  \nAlso, horses are susceptible to many human ailments.  These viruses are transferred just like any virus, through ingestion of some sort.  This means you breath it in if it is a virus that can survive while airborne, or you can eat it, drink it or get it into your body through sores or sensitive areas like your eyes or "other areas"(HIV).  Say an animal is sick and you kill it and eat it.  Maybe the virus withstands great heat and cooking the meat of the infected animal doesn't kill it.  Eating the meat will pass the virus.  You could touch the sick animal, get contaminated saliva on your hands and then you touch your mouth or eyes; you will get sick. \n\nMost viruses are specific to certain species though.  An animal virus only affects animals and a human virus only affects humans.  Still these viruses can mutate into a virus that affects humans and animals.  That is what is so scary about viruses.  They multiply quickly and mutations are very common.

No. I'm not sure where you're making the connection with that, but you get intestinal parasites from eating infected foods. You get HIV by coming into contact with the body fluids of an infected person.

A predator- kills its (animal) prey while or before consuming it.\nA parasite-consumes it's host, usually not killing it.\nA pathogen-produces disease.\n\nExamples:\n\nMosquitoes are parasites, but not pathogens (May carry pathogens).\nMalaria is a parasite and a pathogen, though parasites are usually thought of as larger organisms.\nLions are predators.\n\nAlso, life is not biology.  Usually there are some things that don't fit neatly into a classification.  Life is just too complex, and defies categorization!  That's  what I love about biology.

They are both. There are Good ones and Bad ones. Some parasites such as leeches simply suck your blood out and do nothing for you. Other parasites have what is known as "Symbiotic Relationships" where they help one another. For example, there are birds that nest on alligators. The alligators give the bird safe haven from dangerous predators. The Birds in turn feed on particles of food left in the alligators mouth so they dont suffer from dental problems. They help one another out.

There are indeed parasites that can invade the brain, there is another one called the loa loa worm that is called the eye worm. I have a book with a picture of a work being pulled right out of this guys eye. Anyway is will blind you. And for the parasites in the brain, if someone did get this it is fatal. The good news is you have to go to some really third world countries to get these things.

I found this article on parasites and fish.  Hope it helps.\n\nhttp://www.charkbait.com/article/RAPC2.htm

parasite (like intestinal worms or mosquito).

Parasites are creatures that originally could not absorb the nutrients they needed from their natural environment, so they adapted to be able to forcibly extract them from higher animals. It also refers to creatures whose metabolism requires their gestation to take place in a warm space with ample food (i.e. the inside of another animal)

Most of these disorders are common between humans and animals because homo sapiens IS an animal and we therefore share the same basic cellular structure with all other animals. One classic example is diabetes (which can occur in animals besides humans; you don't see it much because it is selected against in nature), caused by improper functioning of the mitochondria through the lack of insulin production. Cyanide causes death by asphyxiation through almost the same process; the mitochondria cannot metabolize, and death results.

Viruses are not pathogenic (harmful) to all organisms, some act as carriers with no ill effects.  Malaria has evolved to be harmful to humans, but certain mosquitos (anopheles in particular) can provide a suitable habitat in their gut for the virus, or pass the virus along from human to human via blood.  However, the virus has never mutated in such a way that it would harm the mosquitos.

Plasmodium parasites also undergo stages of development. There is a certain stage in their life cycle that they will have to go to a female mosquito body part to propagate and become the phase that is transmitted to humans through feeding. The same goes true also that female mosquitoes are the ones that bite and feed especially at night.Hope this helps. God bless
