2. 10 most common diseases in 2002 Cases Ref: Health statistics year book 2002

3. Objectives To determine the antimicrobial resistance situation of common pathogens for acute respritory tract infections To determine the susceptability of pathogens to antibiotics available in Vietnam

4. Methods Standard microbiology laboratory methods NCCLS (National Center for Control of Laboratory Standards) WHONET

8. Percentage of sensitivity to antibiotics No.AntibioticsH.I. (%) S. Pneu (%) Moraxella (%) 1Ampicilin100 2Ceftriaxone79.397.7 3Cephalothin90.9 4Benzyl-Penicillin58.8 5Chloramphenicol45.580.790.9 6Gentamicine89.7 7Cefotaxime100 8Ciprofloxacin93.588.1

12. Conclusions High resistance to co-trimoxazole Treatment regimen: antibiotics used invivo in line with the results invitro Results of AMR surveillance programme is very useful in preparing treatment guidelines Interventions are needed for the rational use of antibiotics
