happening since 1960s!

What is Antibiotic?Is drug use for kill microbes drug use for inhibit growth of microbes

Antimicrobial Resistance (AMR)

• គឺជាការដែលអតិសុខុមប្រាណមយួមានភាពសាំនឹងទៅនឹងឱសថ

• ដែលពីមុនមក ឱសថទ ោះអាចមានប្ររសិទ្ធភាពសមាា រអ់តិសុខុមប្រាណទ ោះ

• ភាពសាំទនោះ ានមកពីការវវិតតពីធមមជាតិ (Evolution)

• និងភាពសាំដែលានមកពីមបី្រកុរដសែងរក ភាពសាំទែើមបកីារពាខាួនវា ពីររសិា ន និងសាំពាធ ។

The way of People use Antibiotic !

Present and Future Concern

Keep in Mind

We are doctor, not the god.

We use drug to treat diseases, not the magic.
