About this practice session

This page turns the YouTube video “An Introduction to Microbiology 🧫” into an English shadowing exercise. The recording is split into 488 short sentences that you can play one at a time, repeat after the speaker and record your own version for automatic pronunciation scoring.

The speaker talks at about 152 words per minute, a fast pace, with an average of 6.4 words per sentence. That makes it best for advanced learners; slow the playback down or loop each sentence at first.

How to practise with this video

Play the first sentence and listen while reading the transcript. Notice the stress, the pauses and where the intonation rises or falls.
Replay it and speak along with the speaker, copying the rhythm rather than reading word by word.
Record yourself straight after the original. ShadowEcho scores each word for accuracy, fluency and completeness.
Compare your recording with the original, retry the words marked in red, then move on to the next sentence.
Practise 10–15 minutes a day. Coming back to the same video after a few days is an easy way to measure progress.

Transcript (English)

0:00 what is going on beautiful people this
0:02 is medical ces perfectionist where
0:04 medicine makes perfect sense today we're
0:06 starting a new playlist microbiology
0:09 step-by-step comprehensive discussion so
0:12 let's dive into the world of microscopic
0:16 organisms the field of microbiology
0:19 deals with bacteria fungi and viruses
0:22 the field of medical parasitology cares
0:25 about parasites this microbiology
0:28 playlist is for the detailed explanation
0:31 if you want quick reviews check out my
0:33 playlist called picmonic medicosis so
0:35 far this playlist has six microbiology
0:39 videos in the first video we talked
0:40 about these bacteria in the second one
0:43 here third one or here and fourth plus
0:46 five and six if you want the quick
0:48 review now let's get started first of
0:51 all there is a big difference between
0:53 microbiology and medical microbiology
0:56 even the textbooks are different this is
0:58 intended more for biology teachers and
1:01 biology students but this is for medical
1:04 students and doctors the difference
1:06 between them is so stark it's not even
1:08 funny microbiology is like learning the
1:11 bernoulli equation medical microbiology
1:14 on the other hand is like learning how
1:17 to fly a freaking airplane this playlist
1:20 is dealing with medical microbiology
1:22 we're concerned with diseases here not
1:25 counting the freaking amino acids okay
1:27 miracles you will talk about medical
1:29 microbiology will you talk about general
1:31 or systemic unfortunately most if not
1:33 all professors start with general
1:35 microbiology and they make their
1:37 students hate themselves they start by
1:40 telling you how to culture bacteria
1:42 without telling you why with the flip
1:44 would you culture them they tell you how
1:46 your immune system can protect you well
1:48 protect me from what they tell you about
1:50 the diagnostic tests before talking to
1:53 you about the disease this is just a
1:55 stupid way of teaching medicals is going
1:57 to start with systemic microbiology the
2:00 first order of business is to make you
2:02 love bacteria learn about disease adore
2:05 these stories and after we finish
2:08 talking about individual bacteria and
2:10 the disease is caused by each one then
2:13 we can review the general and then i'll
2:15 talk to you about the difference between
2:17 endotoxin exotoxin all of this lovely
2:20 stuff so besides the first few videos i
2:23 will start going to steph aureus right
2:24 away but hey miracles uh steph aureus
2:27 can secrete into toxin but you haven't
2:29 told me what enterotoxin is when we go
2:32 to staff and you hear the word
2:34 enterotoxin it's my job to tell you what
2:36 the enterotoxin is and what's the
2:38 difference between hindu and exotics and
2:40 all of this lovely stuff but you have to
2:42 learn them in context not in some ugly
2:45 nonsensical abstract tables that make
2:47 you have watery diarrhea no pun intended
2:50 microbiology is the study of small life
2:54 microscopic organisms what microbes are
2:57 we talking about bacteria fungi viruses
2:59 and parasites technically parasites
3:02 should not belong in the science of
3:04 microbiology because micro means
3:06 microscopic parasites could be huge for
3:09 example the ascaris the ancillustoma
3:12 these are very long worms they are not
3:15 microscopic by any stretch of the
3:17 imagination
3:18 so lumping them together here it's just
3:20 to make it easier for you but if you
3:22 want the technical stuff this belongs to
3:24 a different science known as
3:26 parasitology now please pay attention
3:28 because this is a very common source of
3:30 confusion there is a difference between
3:33 a parasite that can affect humans
3:36 causing these parasitic infestations
3:38 and
3:39 parasitic behavior because according to
3:42 your work biology professor anything
3:45 that lives in your body taking its
3:47 resources is quote a parasite unquote
3:50 for example the virus can hijack your
3:53 nucleus in this sense the virus is a
3:56 parasite but this is not the same thing
3:58 as parasites from the perspective of
4:01 medical parasitology big difference
4:04 that's why this playlist is about
4:05 medical microbiology therefore we have
4:08 bacteriology phangology or mycology
4:10 virology and parasitology nomenclature
4:13 time kingdom phylum class order family
4:16 genus species when i write steph aureus
4:18 like this staff is the genies aureus is
4:21 the species do not write staff like this
4:25 you should write them in italics right
4:27 staff like this when the name is written
4:30 in italics it could be bacteria fungi or
4:33 parasites viruses are not written in
4:37 italics because the issue of viruses is
4:39 a special situation viruses are not even
4:42 living organisms ergo when i write the
4:45 word hemophilus infill wednesday like
4:48 this it has a totally different meaning
4:50 from writing influenza like this
4:53 the first one is in italics the second
4:56 one is erect it's not italics the first
4:59 one is a bacteria the second one is a
5:01 virus huge difference let's try an
5:03 example we start with the domain in this
5:06 case it's a bacteria after the domain
5:09 there's the kingdom all right after this
5:11 there is the phylum we're talking about
5:14 proteobacterium just as an example after
5:16 this you go to the class are you alpha
5:19 beta or gamma well i'm gamma
5:21 proteobacterium all right now there are
5:24 many of these gamma proteobacterium
5:26 which order we are the enterobacteriales
5:31 and the word enter means gut gi tract
5:34 and then what's the family we are the
5:36 enterobacter
5:39 wow and what's your genus shigella
5:42 what's the species sony so therefore
5:45 from a medical standpoint we only care
5:47 about the last two the genus and the
5:49 species and therefore
5:51 my friend unfortunately you have
5:53 shigella sony what does that cause well
5:56 remember it's part of the entero so it
5:59 causes
6:00 gastrointestinal symptoms what do you
6:02 mean usually diarrhea watery diarrhea or
6:05 bloody diarrhea bloody diarrhea i can
6:08 write shigella sony like this i can
6:11 write s sony like this the first one has
6:14 to be capital the second one is small
6:16 uppercase followed by the lowercase
6:18 uppercase for the genus lowercase for
6:21 the species or if the doctor doesn't
6:23 know that it is sony per se the doctor
6:25 can write it as shigella
6:28 species like this if we do not learn
6:31 from history we are doomed to repeat it
6:34 baby brief history of microbiology first
6:37 mr zacharias janssen first compound
6:40 microscopy i will give you nine times
6:44 magnification as compared to your naked
6:47 eye then circa 1665 robert hook he saw
6:52 cells under the microscope and he called
6:55 these cells boxes because yeah they left
6:58 together like this and they look like a
7:01 bunch of boxes and then my student
7:04 anthony van leeuwenhoek saw the first
7:06 living
7:07 microorganisms and but he did not call
7:10 them microorganisms he just called them
7:12 animacules oh it's like an animal cell
7:15 and a small one it's like the difference
7:17 between node and nodule moon and moonlet
7:21 animal cell versus any molecules next
7:24 miss you louis pasteur said these are
7:28 microorganisms and you can find them in
7:30 the air really yeah really he also
7:34 introduced the concept of pasteurization
7:36 and inoculation and then john tendel and
7:40 ferdinand cohen discovered that some
7:43 microorganisms
7:44 are heat resistant which means you
7:47 cannot kill them by simply cooking the
7:49 food here is my man anthony van
7:51 leeuwenhoek he saw a lumen in the center
7:54 of the cell this is what we now call the
7:57 nucleus of the cell and based on this we
8:00 classify organisms into prokaryotes
8:04 and eukaryotes the word karyo means
8:07 caryon which is the nucleus i have a
8:10 primitive nucleus versus i have the true
8:13 nucleus bacteria are here humans are
8:17 here and then robert discovered that you
8:20 can get anthrax by ingesting
8:23 contaminated animal meat also you can
8:26 inhale a spore from somewhere near the
8:29 animal and you can get anthrax too this
8:32 was followed by joseph lister and his
8:35 antiseptic techniques oh by the way the
8:38 famous mouthwash brand listerine is
8:42 named after joseph lister i bet you the
