DRUG SENSITIVITY TESTING OF 1430
STRAINS OF BACTERIA
Wu Shixiao
Children’s
Hospital, Chongqing Medical University, Chongqing, China
Objective:
To detect the sensitivity of bacteria from patients admitted to Children’s
Hospital in 1999.
Method:
Agar disk diffusion method (Bauer-Kirby method) was used.
Results:
Tienam was the most sensitive drug to 786 strains G -bacteria.
S. Flexner, K.oxytoca, A.lwoffi, were all 100% sensitive, E.coli was 95.5%
sensitive, K.pneumonia was 90.2% sensitive, P.aeurogenosa was 84.2%
sensitive. G -bacteria were also rather sensitive to amikacin,
ciprofloxacin and the third generation of cephlosporins, but the
sensitivity rates to amino-penicillin was <40%. Vancomycin was the most
sensitive drug to 644 strains G +bacteria. S.aureus,
S.epidermidis, E.faecium, S.homonis, S.simulans were All 100% sensitive.
E.facecalis was 97.9% sensitive, S.hemolyticus was 87.5% sensitive. G+
bacteria were also rather sensitive to furadantin, cipro- floxime,
ofoloxacin and SMZ-TMP.
Conclusions:
1430 strains bacteria isolated from patients admitted to Children’s
Hospital in 1999 were detected by Bauer-Kirby method. The most sensitive
drug to 786 strains G -bacteria was tienam and the most
sensitive drug to 644 strains G +bacteria was vancomycin.
