Bacteria have always been a biggest mystery for researchers as they are sometimes good and sometimes bad for human beings and their living. It is said that their are millions of bacteria in our environment but we managed to find out and identify only few of them.

Bacteria which causes diseases in human beings , what we do to treat that disease. We use antibiotics to treat that and kill microbes but what happens when we continuously expose bacteria to antibiotics.

antibiotic resistance, bacteria, health

They become used to of that and ultimately becomes resistant to that particular antibiotic, which in turn leads to inability of antibiotic to kill that particular bacteria. Then that bacteria will reproduce and further progenies of the bacteria will also be resistant to the antibiotic. So how will a doctor be able to cure a person. This is becoming a major problem now. Everyone is engaged to find out the viable solution for this.

Dan I Andresson said, who is the professor at University of Sweden “The results are interesting because they show that the very low antibiotic concentrations present in many environments, too, can lead to a high degree of resistance and contribute to the problem of resistance,”

In a recent study publish in Journal Nature Communications, it has been stated that exposure of antibiotics on bacteria for a very long time will lead the bacteria to develop the resistance. Even when small amount of Antibiotics are used , the same effect is observed. In the experiment which is done on bacteria to see what effects are there on low level exposure and high level exposure gave results as follows:

  1. The bacteria with prolonged low exposure of antibiotic developed resistance that was about thousand times more than initial one.
  2. Bacteria were having mutated genes.

According to WHO, the antibiotic resistance is one of the major threats in coming time so we need to rectify this problem as soon as possible
