Small intestinal roundworms

And if you think I have toxoplasmosis from my itty-bitty perfect little baby kitties, well, you're wrong, fucko, and I will not hesitate to drag you outside by the dick and show you damn well how much I love my fucking cats and none of your damn busi- We also deal with helminths or worms.

Ascaris are huge and live throughout the intestines and look like Satan.

Pinworms are very common and make your butthole itch like a child with a shaved head.

Hookworms penetrate through the skin like bare feet and find blood at music festivals.

The list goes on and on.

So the first, the first one we're looking at here is the Ascaris.

Uh, it's the roundworm.

And these, uh, come from humans and pigs.

And, uh, the Ascaris lumbricoides is one of the largest and most common parasites found in humans.

The adult females of this species can measure up to 18 inches long.

Males are usually shorter.

The juvenile worm then migrates up the air passages into the pharynx, where it is swallowed.

I mean, there's so many different kinds.

Ascaris is one that loves the lungs.

Liver flukes are ones that are kind of UFO-shaped, kind of triangular-shaped, and then they bury themselves into the liver and they eat everything.

So if you have a weight problem and you don't eat hardly a thing, but you smell food and you gain weight, you've got a liver fluke issue.

The phyco-oral route is the most common globally.

This involves ingesting food or water contaminated with the infectious cysts of protozoa, like Giardia, or the microscopic eggs of helminths, like Ascaris.

But ingestion implies, you know, an accidental consumption on the human's part.

Some of these parasites take a much more aggressive brute force approach, like skin penetration.

The human immune system attacks them, resulting in massive inflammation and the formation of granulomas.

which are basically walls of scar tissue built to contain the eggs.

Or consider migrating larvae, like Ascaris roundworms, which physically tear their way through the delicate capillary walls of the lungs to reach the airways, causing localized internal bleeding and a condition called pneumonitis.

Other times, the damage is simply about real estate, right? Space-occupying lesions.
