My research work has always been focused on identifying new ways to control bacterial pathogens. Over the last few years, I have studied how bacteria grow and divide, how they interact with their host during infection, and the host response to bacterial infection. My aim is to find novel therapies to control bacterial pathogens and to understand what makes us susceptible to infections caused by microorganisms, such as Staphylococcus aureus or Mycobacterium tuberculosis . Hello, my name is Anjishnu and I am in sixth grade. I live in San Diego and I have a passion in writing, reading, math, and science.

I want to be an aeronautical engineer when I grow up and would like to design planes that will make flying safer. Enzo is currently coursing the first year of High School. He is

He is fascinating by the English culture and has visited many places in the United Kingdom. He was aware of Fleming’s discovery, and visited the Fleming museum in London. In 1928, Sir Alexander Fleming observed the bacterial-killing effects of penicillin in his laboratory in London.

This was the first step in the discovery of one of the most important pillars of today’s medicine: the antibiotics.

It took many years to find a way to produce penicillin in large amounts, and large-scale production did not start until 1945.

However, to this day, Fleming is considered the father of the antibiotics, and without his discovery we could not treat many infections caused by bacteria. This means that, without antibiotics, even a small infected wound could become fatal.

In addition, surgery is much safer with antibiotics, and people with weak immune systems (like children or elderly) can now easily recover from bacterial infections. However, bacteria are becoming resistant to antibiotics, which was also predicted by Fleming in 1945, during his acceptance speech for the Nobel Prize. They live on us and inside us, and we use them to obtain certain nutrients from food, among many other things (Read more in this Young Minds article; We Are Never Alone: Living with the Human Microbiota [ 1 ]).

But some bacteria, called pathogens , can also cause infections and some pathogens can be very dangerous. Pathogenic bacteria are one of the main subjects of microbiology [ 2 ], which is the study of microorganisms: tiny forms of life that cannot be seen by the naked eye.

Microbiologists have been facing the same questions since bacteria were discovered.

How do bacteria infect humans, and most importantly, is there anything that can be done to stop them?

An individual bacterium can only be seen with a microscope.

However, most bacteria grow well in an environment with lots of nutrients, and broths very rich in nutrients (also known as liquid medium) can be used to grow bacteria [2]. If a test tube with sterile broth and a tiny number of bacteria in it is incubated at a certain temperature, the liquid will become cloudy in a matter of hours and it may even change in color. If a jelly-like substance is added to the broth, and the mixture is heated to melt the jelly, this substance can then be poured on plates (also known as Petri dishes ) to cool down, you will get a nutrient-rich jelly also known as solid medium.

Bacteria can be cultured on the surface of a solid medium.

If we add enough bacteria, they will cover the entire surface of the nutrient-rich jelly. If the bacteria are diluted and spread out enough on the plate, an individual bacterium will replicate so much that it will eventually produce a large group of bacteria visible by the naked eye, which we call a bacterial colony .

If the original source of bacteria contained more than one type, colonies of different kinds of bacteria might be growing on the solid medium.

When we touch just one of those colonies with a sterile object

and

Routinely, microbiologists work with pure cultures to be able to reach clear conclusions from their experiments with a single type of bacteria. However, if their work is not done in sterile conditions, the tubes and plates may become contaminated by other bacteria or even some microscopic fungi living in the environment.

If that happens, most microbiologists discard that culture and start again.

But Fleming was different from most microbiologists.

An Accident Waiting to Happen… On the morning of Monday, September 3, 1928, Fleming was coming back from a family holiday [ 3 ]. Before he went on holiday, Fleming was working with a very common pathogen: Staphylococcus aureus .

Fleming left some glass Petri dishes on his lab bench, with these bacteria growing on the surface of solid medium. Usually, these plates would be sterilized by a laboratory technician to reuse them in other experiments. However, Fleming always had a final look at all his experiments before discarding them, even if they were kept for weeks on the bench (Figure 1A).
