Parasites. They’re all around us, from birds’ nests to litter boxes to our brains, and while plenty of them are harmful to the health of animals like us, some of them can actually be good!

Swelling of the genitals, you say?
How would one aquire one of these parasites? Asking for a friend.
The friend is my penis.
aww yay!! 2012 Hank is just as fun to watch as 2021 Hank
I love seeing presenters/artists at different times in their career, and I love earlier work just as much as later work, they all have their charms 
They forgot the ultimate parasites: Embryos
Toxoplasmosis explains why we are all so fking obsessed with cats.
Actually, Toxoplasmosis doesn't say to a rat, "Look at the beautiful kitty. Wouldn't you like to snuggle up to it? Don't be afraid, it's just a nice friendly cat". The parasite is much trickier than that. Rats know the scent of cat pee and will avoid places that smell of it. They can even sometimes smell whatever few drops remain on the cat's fur after it pees. Naturally they will run away from this scent which is one reason cats have to sneak up on rats and then pounce. However, toxo makes the rats LOVE the smell of cat pee and they will run towards it and even seek it our thereby giving the cat a nice tasty treat and continuing their life cycle. I don't know what category of parasitism this comes under but probably the mutualistic kind since both the cat and the toxo benefit from the arrangement.
Xenomorph has entered the chat and your body.
Bacteria are not animals
come on, Scishow 
I wonder if Hank learned how to spell "malaria", NOT "marlaria".
I have tried many times to watch this series of videos, but the speakers just kill it.
4:56 everyone who touch fresh water bodiew:-well guess ill die
You are actually so much more likely to get toxoplasmosis from uncooked pork than from cats.
I've been wanting to ask this question for years

PICKLE RICK!!!
It's hard to believe that you're the same person
They had learned about fecal transplants and now my life is slightly dimmer
Just about to eat my breakfast and clicked on this video…
As always my timing is just weird!!
Yes ! it going on one month that I got rid of the three parasite all the wanted it place to live, beer, smokes , food and somebody to pay all bills. My life is moving forward with out them.
Can you train or manipulate a parasite to eat cancer cells?
every cell in your body has developed with rna and dna from the serpent worm..
there is no such thing as a good parasite.
THE human being is this planets most deadly and dangerous parasite.
thanks to madcow, and cwd being made avalible for human parasites to consume.
human parasite numbers will reduce to 500 million before 2040 arrives.
I am Ego, the Living Biome!
Okay so within the first 2 minutes I have noticed the following errors: bacteria are not animals, and symbiotes are not parasites. Animals are any member of the kingdom known as animalia or the animal kingdom. Bacteria on the other hand are members of the kingdom known as prokaryotae.
The answer to the question in the title is inside of me. I have never had a parasitic infection in my life.
They won’t go where even ppl won’t go:
Arby’s.
That parasite on the thumbnail looks like Charley from we bare bears!
So let me get this straight. You're trying to tell me it's that we don't have worms that makes autoimmune disorders more prevalent? Not the fact that we're injected with 50 odd immune system tampering injections whilst our immune system is forming? Riiight…
That is the longest thumb, in the thumbnail, I've ever seen
kind of wondering how repeated alcahol use effects the gut biom
Moral of the story, don't eat poop.
Ah Toxoplasmosis! The reason why the internet is obsessed with cats!
Toxoplasma Gondii: "Pet them filthy humans!"
