As a human biologist and researcher, I think these parasites are highly fascinating as they have complex but interesting ways to evade the immune system. In the video, it was briefly mentioned that plasmodium can change the production of its proteins which are present on the surface of the infected cell after a while to be not recognised by the immune system anymore. This switching is called antigenic variation and it is based on shuffeling genes around the genome and modifying histones (proteins around which DNA is wrapped). Although I am not specialised in parasites, feel free to ask anything about the human body and diseases (or stem cells, since I am conducting research in this field)!
@@Poppacap79 Although the exact causes of narcolepsy are still debated quite a lot of different studies point towards associations between the manifestation of the disease and autoimmune reactions (I'll provide you with some primary literature, it might be a bit difficult to read but it gives you a great overview). In a genome-wide association study (a study where you try to find certain variations of genes in certain groups very often (for example patients)) it was confirmed that certain gene variations which are strongly involved in the immune system (HLA or TCR) are comparatively abundant in narcolepsy patients. This gives us a first hint that the immune system might be involved in the manifestation of narcolepsy. Moreover, it was observed that H1H1 vaccination and infection (!) both might activate T-cell mediated autoimmune reactions leading to narcolepsy. Hope that helps!

Legionella does NOT cause walking pneumonia. Legionella causes Legionnaires disease and the less severe Pontiac Fever (similar to Legionnaires but without the pneumonia). Walking pneumonia is caused by Mycoplasma pneumoniae which causes atypical pneumonia, so named because the x-ray does not show consolidation (white areas where fluid leaks into the alveoli which is how typical pneumonia is caused). Mycoplasms are a genus of bacteria are the smallest known bacteria and completely lack a cell wall. Because of this and they also spend their entire life cycle within the hosts cells they are difficult to treat.
Been subscribed to the micro channel since it came out, it's so great and perfect for me. I have a USB microscope I use to look at that type of stuff but I could never capture stuff as good as what they do on that channel so it's great and they obviously have a far better microscope than me, shows me what I might be able to see if I pay a bit more for the microscope next time.
I think that the parasite that infects sturgeon and paddlefish are some of the most worrysome. The paddlefish is endangered maybe critically and the sturgeon ain't doing as well as it could. It would be nice to throw some money in that direction while we're studying parasites in general. Both species are important to their habitats and it would be a shame to lose them.
That last one is definitely serious nightmare fuel. Now to really ruin your day. Sturgeon eggs are caviar, so people have been eating these things for centuries.
if you were to take some microsporidian and mix with with some of those jellyfish monsters with a touch of plasmodium and size it up a bit and you have what is basically an all in one facehugger + Xenomorph right there.
They're a whole genus of bacteria that infect insects. As a whole they might be the most common reproductive parasite in the world. Many are just your usual bacterial infection -if by 'usual' you take into account that since they can only pass down through eggs rather than sperm, many alter the gender balance of their hosts and in fact it seems that many species of parthenogenic insects are that way because the bacteria has eliminated ALL males from their species. But some remain within the host's cells permanently, acting like a sort of parasitic mitochondria. In some species they have replaced the gender determining chromosome so that the infected insects have become a separate species. The deviousness and variety of these bacteria knows no bounds.
Another great example: Some members of Shigella (genus of bacteria that can cause disentary) enter cells and move through and between cells via motility along the cytoskeleton.
heard somewhere before that originally..the mitochondria in our cells were parasites..but a symbiotic type since it gives out energy to our cell and our cell gives nutrients to it..
Parasites! My nemesis! Give me snakes, spiders, blood, guts, needles etc they don't bother me. Give me an ascaris, tapeworm, and any other internal parasite and I'll freak out! Going through the nematodes section in my Zoo class give me major creeps!!

As a biology teacher, these kind of videos are great but would be better made more specific according to classification. For example, in my curriculum we don't study parasites in general, we study them specifically within the taxa of study at that time. So separate videos of bacterial parasites, protistan parasites, fungal parasites, and animal parasites would be more useful.
As a biology teacher, do you have a general definition of a parasite? Because this one is woefully lacking. On top of that, I usually hear that parasites have to be eukaryotes but not everyone defines it that way, they are definitely not here. This has bugged (pun partially intended) me for basically ever and I have yet to find an answer.
@@Tinyvalkyrie410 I define parasite is a form of symbiosis where one species in the relationship benefits at the other's expense. I would include prokaryotes in this definition and even describe viruses as obligate intracellular parasites.
James Zagray So you would define all infectious diseases as a parasite? It seems like there are dramatic differences in the way these things are described. I think I would define it as “a eukaryote predator that eats prey in units of less than one without immediately killing the prey, while also causing damage to the host.” But that’s something I compiled myself from many definitions, and biology is definitely not my area of expertise. Plus it’s really not simple and still has some holes in it. It just seems like there is no consensus on this. But thanks for your definition! It’s always good to hear from someone actually teaching the subject.
James Zagray I think it comes from medical science. They refer to malaria as a parasite and bacteria as an infection. Nobody at a hospital would refer to step throat as a parasite. It’s probably more about how you treat those conditions than anything else. I definitely have found that people restrict it to eukaryotes more often than not, but again, I am not a biologist. It might be that there are simply different definitions depending on your field of study.
What happened to Mycobacterium, I’d have thought those nasty critters would be on that list, though arguably their mode of operation is very similar to others on the list, Tuberculosis is by no means a ‘lightweight’ disease.
Went to the doctor and they said I have a sinus infection and respiratory infection, so I've been using 2 humidifiers and a inhaler. I don't wanna plug them in now. D:
With advancements in nanotechnology, I think that one day we'll be able to develop machines that kill these parasites before they can penetrate the cellular wall. It'll likely be mankind's destiny to become cyborgs.
This was a bad definition of parasite. It would include all infections and most predators. Although I must admit I don’t think I’ve ever seen a legitimately good definition.
Taihus The definition I hear most often says that parasites are eukaryotes, which would rule out things like bacterial infections, and I don’t think anyone would consider a virus a parasite. But this definition would definitely also include things like wolves and all fetuses, and I don’t think anyone would call them a parasite. The point I was trying to make is that almost every time I hear a definition of a parasite it has giant holes in it, and those holes vary drastically depending on who is doing the defining. Edit: and this list DEFINITELY includes bacteria, which I think puts them in the minority, but who the heck really knows. This seems like something people would be able to nail down. The definition I like the most is “a eukaryote predator that eats prey in units of less than one, without causing the prey’s immediate death” but that is a conglomeration of several definitions and still includes and excludes some organisms that most people would or wouldn’t consider parasites.
I'd almost trade my uniquely evolved brain for a uniquely evolved ability to live in and eat caviar all day. I only have this brain so I can do lots of sex, food, and computer games. I think the polypodium has the advantage on two of those activities.
The Clamydia bacteria’s life cycle is very similar to a virus’ “life” cycle. What makes these bacteria different? They can’t reproduce without the host cell either, yet they are still considered life. Viruses are also inert until they reach a host cell. I am genuinely curious.
These things are both fascinating & terrifying. I mean, just look at the truly shocking numbers of humans have been killed by the *Malaria Plasmodium* ( *_Plasmodium falciparum / Plasmodium vivax_* ), alone: *_An estimated Ten Percent (10%) of every human who has ever lived!_* Then you get the shudderingly _creepy_ parasites: like those long, long worms that live in human leg veins, or the tiny creature that lives in a cyst just under the skin & pokes out spiky breathing tubes. The very worst - for the *ICK!* factor - are those things that live inside _human eyeballs_ & can create ulcers at the site of their burrow opening - you can be looking in the mirror and see one stretching out to wave back... ~ ~ ~ It's not quite the same thing, but I also know of *viruses* that take up _permanent_ residence in human cells. One example I actually have in _my own body_ (it's fairly common), is *The Epstein-Barr Virus* , which causes *Glandular Fever/Mononucleosis* by invading the cells of the human immune system (specifically *The "B" Type Cells* ) & residing there (in a neutral state) for decades. I'd appreciate you doing a video about either this specific virus, or these permanent types of infection.

Loving the microbiology theme
With advancements in nanotechnology, I think that one day we'll be able to develop machines that kill these parasites before they can penetrate the cellular wall.
It'll likely be mankind's destiny to become cyborgs.

This was a bad definition of parasite. It would include all infections and most predators. Although I must admit I don’t think I’ve ever seen a legitimately good definition.
infections are caused by parasites
Taihus The definition I hear most often says that parasites are eukaryotes, which would rule out things like bacterial infections, and I don’t think anyone would consider a virus a parasite. But this definition would definitely also include things like wolves and all fetuses, and I don’t think anyone would call them a parasite. The point I was trying to make is that almost every time I hear a definition of a parasite it has giant holes in it, and those holes vary drastically depending on who is doing the defining.
Edit: and this list DEFINITELY includes bacteria, which I think puts them in the minority, but who the heck really knows. This seems like something people would be able to nail down. The definition I like the most is “a eukaryote predator that eats prey in units of less than one, without causing the prey’s immediate death” but that is a conglomeration of several definitions and still includes and excludes some organisms that most people would or wouldn’t consider parasites.
Parasites: it's free real estate 😏
Well done science show 👏
No, this is the most relaxing channel ever... Mmmmm Chlamydia. way to go
And you didn't even mention lawyers.
I'd almost trade my uniquely evolved brain for a uniquely evolved ability to live in and eat caviar all day. I only have this brain so I can do lots of sex, food, and computer games. I think the polypodium has the advantage on two of those activities.
The Clamydia bacteria’s life cycle is very similar to a virus’ “life” cycle. What makes these bacteria different? They can’t reproduce without the host cell either, yet they are still considered life. Viruses are also inert until they reach a host cell. I am genuinely curious.
Little did they know I’m already a parasite 🦠
These things are both fascinating & terrifying. I mean, just look at the truly shocking numbers of humans have been killed by the *Malaria Plasmodium* ( *_Plasmodium falciparum / Plasmodium vivax_* ), alone:
*_An estimated Ten Percent (10%) of every human who has ever lived!_*
Then you get the shudderingly _creepy_ parasites: like those long, long worms that live in human leg veins, or the tiny creature that lives in a cyst just under the skin & pokes out spiky breathing tubes. The very worst - for the *ICK!* factor - are those things that live inside _human eyeballs_ & can create ulcers at the site of their burrow opening - you can be looking in the mirror and see one stretching out to wave back...

It's not quite the same thing, but I also know of *viruses* that take up _permanent_ residence in human cells. One example I actually have in _my own body_ (it's fairly common), is *The Epstein-Barr Virus* , which causes *Glandular Fever/Mononucleosis* by invading the cells of the human immune system (specifically *The "B" Type Cells* ) & residing there (in a neutral state) for decades.
I'd appreciate you doing a video about either this specific virus, or these permanent types of infection.
That video would be Creepy and Cool at the same time. 😅

Be warned, their re-creations of parasitic events are quite graphic!
Can do a whole video on just the worms. There's so many
Waiter, there's a jellyfish in my caviar!
Great video for me to be watching as I eat dinner ...
Same dude
Is there a scientific term for organisms that use other organisms as their home? To be clear, I mean a term that encompasses tapeworms AND gut bacteria, but NOT Mosquitoes or Leeches, as the latter two do not use their mark as a shelter

First pools and now this? I'm staying in a vacuum.
