To answer this question, we have to be able to identify what each particular parasite is responsible for causing and what kind of infection that would be.
00:11
So when we look at severe dysentery, we know that the protozoan associated with this would be entomoeba histolytica.
00:24
So entomoeba histolytica.
00:32
Now, the real question is, how did we arrive at this answer? and unfortunately, the answer is that we simply had to memorize this.
00:39
Now, we can go through our answer choices and eliminate particular protozoans, but at the end, we are still going to have to differentiate between each one and know what kind of infection it will cause.
00:58
So in this case, we know that the correct answer is entomibut histolytica, because it is is an anaerobic parasite.
01:08
It's a protozoan.
01:11
And it is going to infect humans.
01:15
And actually, it infects other primates as well.
01:20
And if we look at how many people it infects per year, it is just a stunning number.
01:27
It's something around 35 to 50 million people per year worldwide...
