Antimicrobial Resistance (AMR)

• គឺជាការដែលអតិសុខុមប្រាណមយួមានភាពសាំនឹងទៅនឹងឱសថ

• ដែលពីមុនមក ឱសថទ ោះអាចមានប្ររសិទ្ធភាពសមាា រអ់តិសុខុមប្រាណទ ោះ

• ភាពសាំទនោះ ានមកពីការវវិតតពីធមមជាតិ (Evolution)

• និងភាពសាំដែលានមកពីមបី្រកុរដសែងរក ភាពសាំទែើមបកីារពាខាួនវា ពីររសិា ន និងសាំពាធ ។

various biological entities are tested on whole, living organisms, usually animals, including humans, and .

• ២. In vitro: In vitro studies are performed with microorganisms, cells, or biological molecules outside their normal biological context

Keep in Mind

We are doctor, not the god.

We use drug to treat diseases, not the magic.
