Hello students, in this question we have been told that when two bacterial strains are orally ingested by mice, bacterium a has an id 50 of 10 ,000 and b has an id 50 of where infection is indicated by recovery of significant number of bacterias from feces.
00:31
However, when the two bacterial strains are intraperitoneally injected, the ld50 for a is equals to 10, whereas ld50 for b is equals to 10 ,000 based on morbidity.
00:57
So we have to draw the ida 50 and ld50 curves for each bacteria.
01:05
To draw this, we need to plot percentage of infected mice, number of bacterias or the number of bacterias that were recovered against the dose.
01:19
That too in the log scale.
01:24
So the x -axis represents dose and y -axis represents percentage of infected mice.
01:37
So the curve will start at a low percentage and gradually increase as the dose of bacterium a increases.
01:44
At the dose of 10 ,000, the curve will reach 50%.
01:51
For bacterium a in the ip model, the x -axis represents the dose of bacterium a.
01:57
The curve will start at a low percentage again and at the dose of 10, it will reach 50%...
