hey everybody dr. Oh here this is part two of the series where I'm just briefly introducing the different types of microbes are going to be exposed to pun intended in microbiology this semester mainly to see you recognize them like we'll talk about specific examples when we need to so I left for this second video all the different eukaryotes so we already talked about viruses which aren't cells and the bacteria and which are your prokaryotes and then your archaea but now we're going to talk about the different types of eukaryotic organisms that are a part of microbiology so we have the protists and the fungi and we'll even go through the pair of multicellular parasites it here at the end so just real quickly like as a group what I find most interesting or something we have to pay the most attention to is if you're trying to kill a pathogen that's a eukaryote it is much more difficult that's because these cells are eukaryotes so are your cells so we have to find chemicals that kind of like using chemotherapy to kill cancer right we have to find chemicals that can kill the pathogen without harming the host it's a lot easier when you're dealing with a bacteria that is so much different than us so that's just kind of important generally so here the first group I want to talk about are the protozoa so these are single-celled eukaryotes they would fall under that category of protist because they're not they're not plants or animals or fungi so they they go around and they actually will absorb and ingest organic chemicals like we do so many of them are parasitic but they can also be free living the ones we care about us give you a few that will come up this semester we have Giardia lamblia so that's a pretty common organism leading to diarrhea getting it from contaminated water is pretty common toxoplasmosis so toxoplasmosis gondii i is is something we'll definitely talk about because it can lead to all interesting things in cats are actually in rodents that are attracted to cats but also can cause problems in some humans and then here we're looking at is Naegleria fowleri hard to say on this is the brain-eating ameba which only slightly more than a hundred americans have ever been infected with it but it's actually in lots of places but it kills almost everyone I believe there's only been three Americans that have been infected with the brain-eating ameba that have survived so all right those are protozoa next you have your fungi often called fungi depends on where your and how you learned it so there they are eukaryotes same thing they're gonna absorb chemical energy from their environment the key thing here is that if they're single-celled organisms that they're unicellular they're gonna be yeast like this here this is Candida albicans which can lead to vaginal yeast infections or oral thrush so this would be a yeast a single-celled fungi if you have multicellular fungi those are gonna be your molds and your mushrooms so we definitely will be talking about mushrooms and in class unless we're talking about how tasty the morel mushrooms are but molds are clearly significant molds can lead to many different types of infections they can lead to chronic inflammatory response since syndrome that can make you a very ill as well so we'll talk about them some so those are your fungi your yeasts and your molds primarily and then we have the algae I like think of algae is just single-celled plants right they they have Salo cell walls just like plants do they're photosynthetic just like plants produce oxygen produced their own carbohydrates so they really really are a single-celled version of a plant if you want to look at it that way if you ever hear about diatoms or diatomaceous earth so diatoms are a type of algae that's kind of interesting I guess more than anything and then the last group is the multicellular animals i'ts that there are eukaryotic there ant they're small animals they are not technically micro organisms right but they have mike-mike rakaat microscopic stages in their lifecycle but you can say that what everything right I was microscopic at one point I guess but that we do company classify we teach about them in microbiology because they are they are they cause infectious diseases so I'm often these are not gotten gotten from pertinent person-to-person they come from water and those types of things so what you're looking at here so we'll cover several interesting examples throughout the semester but then we're looking at here is dracunculus Medan iNSYS which is the which is as you see what it's actually as you can it's the guinea worm is what it's called you can see that's actually a match stick so this this this organism is coming out of this person's foot to lay eggs by the thousands and how you extract them is you slowly wind them around a stick or in this case it look it looks like it's a match but you only do a little bit at a time because you don't want to actually tear it so then you would take this and the next day you try to pull it out some more thankfully the guinea worm is almost gone because of our ability to filter water to remove the guinea worms eggs the guinea guinea worm is hopefully the next disease that may just be completely eradicated we'll see all right so those are the eukaryotic microorganisms that will be covered here in microbiology I hope this helps have wonderful day be blessed
