The snake on the staff comes from Moses. People were saved by looking at it, so it became a sign of salvation, appropriate for the medical field.
Or were you joking?

Scott Westerfeld’s book Peeps is about vampires (though the characters avoid the “v” word). It explains vampirism as a form of parasitism and every other chapter is about real parasites, some of which are included in the preceding blog entry.
It also discusses toxoplasmosis (a parasite found in cat feces) and discusses evidence that it has influence the minds of humans.

The crab parasite’s actually even worse than the description given here - it’s not a slug, it’s a kind of barnacle. A crustacean, like the crab.
http://www.mesa.edu.au/friends/seashores/crab_parasitism.html
The host crab is chemically castrated, and the distended growth at the base of the abdomen is the barnacle’s brood chamber - and how does it breed?
“A male cyprid of the same species of barnacle attaches itself to the opening of this brood chamber, and then grows inside a special chamber within the female barnacle which itself is inside the body of the parasitised crab. This male growth forms into a testis. The female then effectively becomes a hermaphrodyte, which means that it can fertilise itself.”
A parasite of a parasite.

A very readable account of parasites can be found in the book “Parasite Rex” bt Carl Zimmer.
http://carlzimmer.com/parasite_1.html
All six parasites are mentioned in the book.

The ‘Leucochloridium paradoxum’ (LP) pathology is even weirder than the aricle states. I understand that LP will not survive an adult bird’s stomach acid, so the bird cannot eat the LP it plucks from the snail.
The bird must feed LP to its chicks which have much weaker digestive juices, where it will continue to live and spawn in the birds intestinal track.
Rinse - Lather - Repeat.

I thought the snakes on the staff were from ancient Greek mythology. The Staff of Asclepius.
After digging some more I saw that this symbol has been attributed to Moses much alter on. It seems that some people like to attribute everything to the bible.

#1: The caduceus has nothing to do with Moses. It originated as the symbol of the Greek god Hermes. More at wikipedia

Also, another interesting aspect of the ‘Leucochloridium paradoxum’ is that is alters the behavior of the snail. These snails usually stay under leaves to avoid predators, but when infected, they helplessly wander around the tops of leaves, in plain view of the predatory birds.

#16: The Aesculapius staff has only one snake.
#17: Correct. The caduceus is related to Hermes and is a symbol of peace. It’s a Greek badge of honor.When the U.S. Army Medical Corps adopted the Cadeuceus it was because it was similar to the staff of Aesculapius, the Ancient Greek god of medicine. The Aesculapian staff is what the American Medical Association uses.
Personally, I would be more terrified of the Candirú than many of these. This is the one that is the stuff of urban legends. I will leave it to you to read on wikipedia.

I was going to mention pin worms, but that thing in the dude’s foot kicks a pin worm’s ass (if they have asses) any day of the week. For the parents in the crowd, if you weren’t nauseated enough by these little horros go do a search for pin worms.
You can thank me later.

*happy sigh* nice to see somebody else with an appreciation for our little cunning cousins.
I cover various parasites at length in my LJ - starting with parasitic genes, and working thru allograft cancers that are passed as seperate organisms from host to host, thru the viruses, plants, fungi, protozoa, simple animals, and so on - currently about to embark on the Ecydozoa (that should keep me busy for a few months)
anybody interested in learning more about them is encouraged to have a look

good morning too all of my old good friends from old news baby that would not vote for any of my websites
and that is why you have not seen me this year posting on the brand new old news baby website but i do have alot of great brand new websites saved up that i will never post because i know that you will never give me enough points to win and i have been reading about all of your complaints about the brand new old news baby website not working right. so why have none of you emailed me all this year to keep me around and become great friends with all of this brand new free time that we have from not posting on old news baby ? any way these parasites get my vote this morning so keep on sucking hahahaha -

Actually, the last sentence of the piece is correct as written. The comma placement implies that the subject “snail” is connected to the three verbs “shakes,” “shops,” and “vows.” Rewriting “the snail” three times would make the sentence sound ridiculous.
I don’t know why I care enough to tell this to you…I just do.

You forgot about the wasp, Ampulex compressa, that taps into a beetle’s brain and then uses its chemicals to steer it back to the wasp’s nest.
Read about it at Carl Zimmer’s Loom:

I guess if you were really unlucky, you could get a screwworm, filarial worms and Guinea worms, whilst the “crabs” you suffer from thanks to that trip to the shop with no windows last year all get a sacculina carcini. Goodness only knows what they would do to your genitals!

“I thought the snakes on the staff were from ancient Greek mythology.”
Myth, Myth! From ancient Greek myth! Sorry this is a big pet peeve of mine. The stories themselves are myths. Mythology is the corpus of writing that analyzes myths. It’s somewhat similar to the difference between History and Historiography. You wouldn’t say you are a military historiography buff, when what you enjoy reading is John Keegan and Stephan Ambrose.

Well….I have this Biology teacher. He is a unique guy with “special” interests. Don’t get me wrong, I’m greatful because this means exciting essay topics that are easier to write.
Before, the topics ranged from parthenogenisis (asexual reproduction) to chimerism (people who have varying DNA through out their body i.e. their top organs do not match their bottom organs). Now he gave us an article about the Guinea Worm Disease.
Obviously, curiosity got the best of me and here we are…with belly aches.

Quite gross, but also fascinating, in a freaky kind of way.
Animals are not the only ones who succumb to parasitic mind control:
http://www.livescience.com/strangenews/060803_tgondii_culture.htmlAbout half the human population (3 billion people) are infected with T. gondii.
The parasite is thought to have different, and often opposite effects in men versus women, but both genders appear to develop a form of neuroticism called “guilt proneness.”
And I thought that affliction was due to me being raised as a Catholic.

i remember watching videos on parasites, which i think included all of the above, in a biology class…
some guy ate a cyst or something similar from raw cows flesh and grew a tape worm (or some other sort of worm)… i think he had some mental problems, but it was actually, while disgusting, fairly interesting…
there was one part where the worm crawled about an inch or two out of a cut on his arm…
and I’ve lost my appetite just thinking about it again.

To the very first person who posted:
The medicinal staff dates back much farther than Moses. It was originally a Greek symbol stolen by the Christians (as were the majority of Christian symbols) and it DID mean specifically “to heal”.
Take a history class.

I think you’ll find that the Snakes around a staff does not come exclusively from Moses (Numbers 21:4–9). It was from an Ancient Greek legend like much of medicine’s symbolism. The Snakes wrapped around a staff was astrological and is known as “The Rod of Asclepius”. Asclepius was supposed to have been the son of Apollo and was a practitioner of medicine.
