MICROORGANISMS -POST -2

GOOD MORNING


IMPORTANT REMINDER-

*We at St Columba's School, are ready to take the next step - and move towards using Google Classroom as a tool to enhance the teaching learning environment.

*This shift involves the school giving each student a unique email address, which he will need to setup ( the teachers will assist him in doing the same). This email will facilitate each student to interact with his teachers.

* The student should use this email ID only for:

-interacting with  teachers on school /subject related matters

-keep the words and expressions as he would- if he  were interacting with us as a Columban student

-use the facilities connected to this email ID only for google meets organised with the permission of a teacher 

-he should have a copy of the permission given ( when and by which teacher and for what purpose)

-do not access any of the other facilities connected with this email address unless he first seeks the permission of a teacher

(He should have a copy of the permission given - when and by which teacher and for what purpose).

*Please note that Google and St Columba's have legal obligations by giving you access to this email address and hence,

you will need to sign an agreement when creating this email ID. 

*Be informed that the history of use of this ID shall have a digital footprint !

        CHILDHOOD MEMORIES ;)      

Welcome back and I really really really hope that you have finished doing your written assignments of the previous post.

You must be clear about certain facts from the previous post:
 Check out this recap video. And then ask yourself the questions that follow.

Do I know?

What are the different types of microorganisms?
Where are microorganisms found?
What is the difference between a bacteria and a virus?
How does  bacteria multiply?
How does a virus multiply?
How do the useful bacteria help us in our lives?

If you know the answers to the above questions, you may proceed. If not, please revisit the previous post, clarify your doubts and then go ahead.

 The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic.

The first antibiotic was penicillin. Penicillin-based antibiotics, such as ampicillin, amoxicillin, and penicillin G, are still available to treat a variety of infections.

A doctor prescribes antibiotics for the treatment of a bacterial infection. It is not effective against viruses.



                  

If people overuse antibiotics or use them incorrectly, the bacteria might become resistant. This means that the antibiotic becomes less effective against that type of bacterium, as the bacterium has been able to improve its defenses.

Antibiotics commonly cause the following side effects:

                                                                          

• diarrhoea
• nausea
• vomiting
• rash
• upset stomach

IMMUNISATION AND VACCINATION

I'm sure that you must have had most your vaccinations by now and gulped down a couple of antibiotics in these last 13 years of your life.

Could you name three of your vaccinations and what were these taken to prevent?

Immunisation  describes the process whereby people are protected against illness caused by infection with micro-organisms (formally called pathogens).

 A vaccines stimulates the body's own immune system to protect the person against subsequent infection or disease.

It is interesting to know that a vaccine is a small dose of weakened or killed disease causing microbe  that is injected into you and is needed to immunise the body against a particular disease.

Have a look at this video.

This second video is for the students who would like to delve a little deeper and know more about how does a vaccine work and about the different types of vaccines they are.

So, when you get a vaccination:

• the body produces antibodies 
• these antibodies kill the weakened or dead disease causing microbes
• these antibodies remain in your blood 
• if your body is attacked by the same disease in future, these antibodies present in the blood recognise the danger and kill the disease causing organism

                                        HOW COOL IS THAT !!!!!!!!!!
