Okay, so the first question is asking about which of the following epidemiological routes of infection applies to cox postulates to study a disease.
00:11
So if we recall, cox postulates is essentially isolating the microbe, or rather we have a diseased population.
00:24
From this disease population, we are able to isolate a microbe.
00:31
We're able to then take this microbe and isolate it, culture it.
00:43
We can then take this microbe and put it in a healthy organism.
00:58
And then after doing so, that healthy organism then becomes sick.
01:18
And then from this newly sick person, we have the same kind of bacteria that is being isolated.
01:28
That's coax postulate in a nutshell.
01:30
And the best answer, rather what really follows this pathway, is b, the fecal oral route.
01:46
Okay? sick person has gastrointestinal disease of some sort, gets it on his or her hands.
01:56
This bacteria then is transferred to a newly healthy patient.
02:00
This healthy patient then gets sick.
02:01
And then this cycle just starts over and over again.
02:05
Okay? so to answer one, it is the fecal oral route.
02:15
All right, let's get to question two.
02:18
Which of the following is transmitted by the parentarial routes? parenteral literally means beyond par, beyond enteral, beyond the enteric system.
02:30
But that's just a fancy way of essentially saying injection.
02:33
So, parental route, injection...
