Good Parasites, Bad Parasites, Weird Parasites
Uninvited guests, but they too have a conscience!

What kinds of parasites can inhabit our bodies? Which ones are so harmful that even a single one can cause significant harm, and which ones are harmless enough to survive in a few? While they may seem harmless, are there also parasites that are beneficial? Can we avoid parasite infection as long as we're careful about what we eat?

Here are the answers to those questions.
This book introduces parasites that infect humans and cause disease, and provides an interesting explanation of how parasites are born and grow, where they move, what route they take to become infected, what symptoms they cause, how to detect infection, and how to treat them.
Most parasites try to live quietly without causing harm to their hosts in order to live comfortably.
But not all parasites are docile and kind.
It can also cause fatal damage to intermediate hosts, which are only passing through the process, rather than the definitive host, which is the host in which the virus will continue to live.
The scary thing is that we are not the final host for all parasites.
Malaria, toxoplasma gondii, sparganum, and lymphatic filariasis, of which humans are intermediate hosts, are 'bad parasites' that we must be careful of.
There are scary parasites that move towards the legs when it's time to give birth, causing hot, painful blisters that force the offspring to jump into the water, breaking through the skin to achieve their goal of reproduction, and there are also nasty parasites that cause one leg or one testicle to become extremely large, and even with treatment, they never return to their original shape, requiring plastic surgery.
Dangerous parasites are mainly transmitted through stimulant foods such as snakes and frogs, and common parasites are also transmitted through uncooked foods such as raw fish or raw liver, so there is not much worry about being infected with parasites as long as you are careful about what you eat.
However, since notorious parasites such as Streptococcus gambiae and Lymphatic Filariasis are mainly transmitted through mosquitoes, you will only get infected if you are really unlucky.
The good news is that in our country, there is virtually no risk of being infected with such parasites.
However, we must not let our guard down. Malaria, a parasitic disease that was thought to have been eradicated and is transmitted through mosquitoes, began infecting soldiers on the front lines and is now affecting more than 1,000 people every year, regardless of whether they are soldiers or civilians.
And parasites that increase the rate of infection are also quite a problem.
Although pinworms do not cause serious symptoms, they are especially worrisome because they have a high infection rate in children. This guy can infect family members or classmates in large numbers through snacks given to them or by holding hands, and the rate of reinfection is also high. In addition, any place touched by an infected person becomes a source of infection, so not only group treatment but also steam cleaning and sterilization of bedding are required, so treating the infected person alone is not the solution.

"A mean but not greedy parasite" If I had to describe parasites in one word, it would be this.
Parasites do not survive on their own but depend on their hosts, but even if they live in an obese host with plenty of food, they only consume as much as they need, so they maintain a slim body.
In other words, since there is no greed, there are no obesity parasites.
And I try to be as quiet as possible and not cause trouble.
Going one step further, there are parasites that are beneficial to humans.
Among the parasites, the safest one is the pig whipworm, which is the 'good parasite'.
Many patients have seen improvement in their condition after the introduction of a treatment method that uses pig whipworms, which live for only two to three months and then die, instead of medication for allergies or Crohn's disease. There has also been a successful experiment using schistosome eggs to prevent diabetes.
This is good news that parasites can be symbiotic rather than parasitic.
That is why good parasites are important.
And let me introduce another role of parasites. It is the work of parasite eggs in a field called paleositology, which studies parasite eggs such as roundworm eggs and whipworm eggs that were inside mummies or icemen (it is difficult to find traces of parasites, but parasite eggs are found in most mummies) to correct historical misconceptions.
Parasites do many things we never thought of.


The Unusual Survival of Strange Parasites

Among parasites, there are many cases where they wander around the human body and die while needlessly exploring it.
Since they broke through the egg shell in the duodenum, they should have gone down to the factory a little below where they were born and settled there, but the 'strange parasite' roundworm is one of them that goes through the heart and lungs, reaches the end of the trachea, and jumps into the esophagus.
Going up against the prayer is quite difficult, so there are many cases where one fails here, and as one continues to go up, one unexpectedly comes out of a person's mouth, startling the host and surprising oneself.
Fortunately, it goes down the esophagus and settles in the factory, but the reason why it goes around in circles and almost dies when it could have just gone down a little is not known.

This book, which entertainingly unravels the mysterious and unique stories surrounding these good, bad, and strange parasites, is a must-read when considering the current high infection rate (over 1.5 million infected people), which is by no means low, with 2.6 to 3 out of 100 people infected, and the Korean food culture that favors raw fish and stamina-boosting foods.


Netizen Praise (Comments on Navercast Serial)

I read all of the Navercast articles written by the professor.
This is really crazy writing.
It's amazing how you can write about these strange, jingling, twisted creatures in such a fun and engaging way...
I'm learning good information and laughing at the same time.
- Shihu

Professor Seo's writing is truly alive, unlike other casts that are formulaic, dry, and sometimes insincere, as if reciting a dictionary.
One person who will become a fan of Professor Seo in the future - Reeves

I'm a huge fan of Professor Seomin!! I think you write really well and in a fun way.
I'm an engineering student, but biology was my weak point. I can understand your writing very well.
- The wind is dreaming

As expected of a down-to-earth professor! Whenever parasites are mentioned on Navercast, I click on them.
Your handwriting is amazing.
