AMR occur when antibiotics lost the ability to control the growth of microorganism so that they continue to multiply. Some bacteria are naturally resistant while the other may get this ability of resistance either by the gene mutation (which changes the genetic material of the bacteria) or by acquiring the resistance from other bacterium (by the process of conjugation which transfer the genetic material along with the coding gene resistant to antibiotics).
The discovery of the antibiotics was a significant change in the human history as the antibiotics bring change in the field of medicine in many respects and many lives have been saved. The presence of antibiotics without any negative coefficient has changed the public health and this has been the reason of countless improvement in medical care (Spellberg et al., 2008). The resistance of microorganisms have unfavorable effects on human health and the result includes the infections that may increases the chance of failure of

These samples were diluted in the 0.9% saline solution. Mannitol salt agar (MSA) media was prepared by adding MSA and sufficient distilled water was added to make the media 1 liter. This media was autoclaved at 120 degree centigrade. The media was cooled for some time and then it was ready to make plates. Bacteria soil samples were spread on the prepared cultural plates with the help of cultural swabs. Kept these inoculated cultural plates in the incubator at 38⁰ C for 24 hours. After 24 hours bacterial colonies were seen on the cultural plates. Colour of these colonies was yellow so that indicate the presence of Staphylococus on the
