Slide 3

Today's Agenda: Introduction Safety The Life and Death of Bacteria Basic Practice Techniques Surveying Different Kinds of Media Closing

Slide 4

Introduction: All living things contain cells Eukaryotes: more than one cell Prokaryotes: one cell life forms

Slide 5

The Boring (Yawn!!) Eukaryotic Plant and Animal Cells…

Slide 6

The Exciting Bacterial Cell…

Slide 7

What are Bacteria? Microscopic organisms are prokaryotes, which means they are just a single celled living beings. They are little and can be hurtful or helpful.

Slide 8

Follow along… You have a photo of a bacterial cell at your work area. Take after alongside the accompanying graph, ensuring you comprehend what each structure is and how it functions.

Slide 9

Bacterial Cell Components…

Slide 10

Bacteria come in a wide range of shapes and sizes… investigate…

Slide 11

what number microscopic organisms will fit on the leader of a pencil, similar to the one you utilize each day?? How huge are microscopic organisms?

Slide 12

1 MILLION microscopic organisms could fit onto the tip of that one pencil!!

Slide 13

Bacteria can reproduce effortlessly… To develop, microscopic organisms partition and gap and gap once more. Issue: If you began with just 1 microorganisms cell, and it separated 10 times, what number of microscopic organisms would you then have??

Slide 14

Bacteria are all over the place… Don't freeze!! This is something to be thankful for. Microscopic organisms are a piece of our lives, our biological community and our natural surroundings!

Slide 15

Bacteria can bring about illnesses, similar to we as a whole know…

Slide 16

Bacteria can have gainful utilizations…

Slide 17

As well as those useful uses… There are numerous microscopic organisms which people require each day. They live on us and in us and we NEED them!!! They are called our "Ordinary FLORA"

Slide 18

Normal "verdure" Flora – microorganisms that are generally discovered related with solid body tissue What does that mean? Ordinary verdure are microorganisms which our body needs and play a "decent" role to help us remain sound.

Slide 19

Let's take a gander at the distinctive regions "greenery" live… and after that we will test them!!

Slide 20

Normal vegetation of the Skin is viewed as a "brutal" situation for microorganisms, why? Microorganisms like the regions of the skin which are clammy; underarms, sweat organs and so forth. Most are not destructive, but rather Acne… Ie: Staphylococcus, Propionibacterium acnes,

Slide 21

Normal verdure of the oral pit Streptococcus is a typical microorganisms in your mouth Other microbes are additionally present that transform sugars into acids and cause dental plaque, depressions and rot Brushing our teeth permits the ordinary greenery to develop without develop of other microscopic organisms!!

Slide 22

Normal greenery of the GI tract The GI tract is the stomach, small digestive tract and internal organ. A few distinct sorts of microorganisms live in the GI tract and help in assimilation, development of waste and retention. Ie: E. coli, Clostridium, Enterococcus faecalis,

Slide 23

Normal vegetation of the Urogenital Tract Urethra (tube from which you urinate) have typical microorganisms exhibit, yet they can get to be "pioneering" when there is an adjustment in the earth and bringing about disease Bladder and conceptive organs ought to dependably be sterile

Slide 24

Normal verdure of the Respiratory Tract Upper: oral hole and throat microorganisms live in the territories around mucous films Ie: Staph, Strept, and some gram negative Lower: trachea, bronchi and lungs ought to ALWAYS be sterile, if not – pneumonia

Slide 25

Lab Information… Pay Attention The accompanying is a prologue to a portion of the media we will utilize today… Pay consideration!!

Slide 26

Different Kinds of Media We "develop" microscopic organisms on various sorts of media. "Media" implies a situation inside a Petri dish that has certain attributes We will go over the sorts of media we are utilizing today

Slide 27

MacConkey Agar Media MacConkey is particularly intended to help microbes that live on the skin to develop "Gram Positive" microscopic organisms Grows pink, purple and white hued states

Slide 28

Mannitol Salt Media Mannitol Salt is particularly intended to help "gut" living beings develop. "Gram Negative" microscopic organisms Yellow = gut life forms exhibit No change = no gut living beings show

Slide 29

Nutrient Agar Media Nutrient media is NOT specific (G+ and G-) This implies most all microorganisms LOVE to eat supplement agar It is the most widely recognized media, and we will utilize it A LOT!!

Slide 30

Now, we should proceed onward to our lab convention. We will review better places where the distinctive "skin" and "gut" microscopic organisms develop Where might be some great spots to discover either? Where are a few spots to discover them, where they truly SHOULDN'T be?

Slide 31

Anti-Microbial Testing Goal: To perceive how the items we use in our homes influence the diverse microscopic organisms we know are around. What sorts of items are out there?

Slide 32

Disinfectants are substances that hinder bacterial development THEY ARE ALSO HARMFUL TO HUMAN TISSUES!!

Slide 33

Disinfectants are substances that hinder bacterial development THEY ARE ALSO HARMFUL TO HUMAN TISSUES!!

Slide 34

Disinfectants are substances that restrain bacterial development THEY ARE ALSO HARMFUL TO HUMAN TISSUES!!

Slide 35

Antiseptics are concoction substances that repress bacterial development THEY ARE NOT HARMFUL TO HUMAN TISSUES

Slide 36

Antiseptics are compound substances that restrain bacterial development THEY ARE NOT HARMFUL TO HUMAN TISSUES

Slide 37

Antiseptics are synthetic substances that hinder bacterial development THEY ARE NOT HARMFUL TO HUMAN TISSUES

Slide 38

What do you think? Will germ-killers, which we use on our bodies, be more viable on Gram pos. on the other hand Gram neg. microbes? Shouldn't something be said about disinfectants? How do each do against the microorganisms on our plates?
