The papers that Pasteur published regarding the germ theory of disease and disproving the theory of spontaneous generation were read by his contemporary Joseph Lister, a surgeon battling high post-surgical mortality in his patients. Lister had studied inflammation and suspected that wound sepsis was caused by an infectious agent in the air. Pasteur's work solidified his hypotheses so he began to use phenol before performing an operation, drastically reducing the number of deaths in patients following surgery. disease phenol infection Reset

Transcript

00:01 Hello students, so today's first question is which of the following is not aspect of the pastures experiment to disprove the spontaneous generation.

00:12 So to disprove the spontaneous generation, we know that the loose pasture did the experiment.

00:18 And out of the following options, which was not the part of the pastures experiment.

00:24 So first was the boiled infusion to kill any microbes.

00:27 So yes, the broth.

00:28 The broth he used, broth he used, he boiled it.

00:35 He boiled it to kill any microbe.

00:40 Kill any microbes.

00:41 So this is correct.

00:43 So this is correct option.

00:45 So we can eliminate it.

00:47 Eliminate it.

00:48 Now that was flask were incubated for long time.

00:52 So this is true.

00:53 This is true also.

00:54 So this can eliminated.

00:56 Flask were free of microbes until they opened.

01:00 Yes, flasks were free of microbes until they opened.

01:05 So, so pasture, what he did, so pasture broke the, broke the flask and the microbe entered through the ear.

01:17 Microbes entered through air, through air.

01:24 So this option is also true and we can eliminate it.

01:28 Now next is neck of flask he used were bent into s shape.

01:32 This is also true and we can eliminate.

01:34 So flask were sealed with cock.

01:37 No, this is not true.

01:39 He never sealed.

01:40 He never sealed any flask.

01:42 So the flask experiment was like this.

01:45 He used the broth.

01:47 He used the broth and in various flask to sterilize it.

01:52 Then let it cool.

01:53 Then the flask was cool.

01:56 Down and when as the broth and the air in the container cooled the fresh room here then the air was drawn into the containers into the into the flask but none of the flask were none of the flask were sealed so this happened when he broke off the flask when he broke the flask so and the microbes entered through the air microbes entered through the air next is major drive for the microbiology.

02:33 Microbial classification, food preparation, etiology of infectious diseases, genetics and the industrial microbiology.

02:42 So microbiology is very important where we can study the many microorganisms.

02:48 So studying about microorganisms, we can study the kind of diseases they cause.

02:55 They can cause and also we can study the origin behind the origin behind the diseases and we can study the microorganism behavior and we can stop the we can prevent the diseases so it is very important for the etiology of the infectious diseases ideology of the infectious diseases ideology means the origin next is chemicals that would kill the microbes and not human was foundation for the chemotherapy.

03:29 And out of the following scientist who thought about this.

03:33 So second, erlich is the correct answer.

03:37 It was the correct answer.

03:39 So paul erlich was the german scientist who did, who discovered the para -rosanilin to treat the, to treat the, tri -penosoma effect...
