This Bacteria Experiment Shows Us How Scary and Dangerous They Can Get!


If you use antibiotics, especially without a doctor's recommendation or without considering warnings, check out this experiment. 

Let's find out how fast bacteria can become resistant to antibiotics:

Scientists used the intestinal bacteria E.coli for this experiment.

They designed a petri dish called "Mega plate," to observe E.coli's evolution.

Its size is around 120x60 cm. 

For those who aren't familiar: A Petri dish is a container made of plastic or glass with an agar plate added in order to grow microorganism cultures. Agar gives the bacteria an environment to comfortable grow, reproduce and die.

They divided the petri dish into 9 sections and put different, equally increasing levels of antibiotics in each of them starting from each end.

The outermost sections had no antibiotics, and each following section had an amount that is 10 times concentrated. The middle section had the highest antibiotic concentration.

After planting the last bacteria, they recorded the process.

The results show how dangerous the situation could become for humans.

The bacteria reproduces easily in the sections with little to no antibiotics. The problem starts in the following sections.

In the area shown with the arrow, the bacteria that mutated started to reproduce.

In other words; resistant bacteria.

The mutated bacteria transferred their genes to the other generations and kept reproducing despite the amounts of antibiotics.

At the end of the 11th day, we can clearly see how the mutated bacteria is spread across the petri dish.

The fact that resistant bacteria reproduces so fast in such high concentrations shows just how dangerous a threat bacteria pose to our lives.
