00:01
So we have been given the vectors for bacterial diseases and we are asked to find out the organisms morphology and the disease and the system affected.
00:11
So first is xenopsis.
00:15
So we can write us x -ciopsis.
00:18
It is commonly called as oriental ratfly.
00:23
It is a common vector for the bacterium.
00:28
Arsenia pestis.
00:29
You can read it as y pestis also.
00:32
So ercinia pestis is a bacteria which is gram negative in morphology under microscope.
00:40
So this ercinia pestis causes the infection what we call as plague.
00:46
So what the plague does is it infects the lymphatic system.
00:51
We can write it as lymphatics.
00:53
It causes necrosis of extremities and ultimately death.
00:59
So what is the same? second vector.
01:01
It is pedicularis corpus.
01:03
We can write it as p corpus.
01:06
What is the common name for pedicularis corpus? it is body louse.
01:12
So body louse, what does it transmit? mainly transmits three disease.
01:17
We can take one disease for this example, which is rickettsia provosecchi.
01:24
So this rickettsia provisaki causes typhus fever or we can add it as epidermic.
01:35
So epidemic typhus is caused by body louse that is that transmits the rickettsia provosaki.
01:43
So this bacteria is also gram negative.
01:48
So this causes typhus, it is epidemic typhus.
01:52
And the manifestation is they damage the circulatory system...
