Objectives To evaluate mini/VITAL and BacT/Alert, two fully automated blood culture systems. Methods Standard mini/VITAL AER and ANA bottles (bioM′erieux, Marcy 1′Etoile, France) and BacT/Alert FAN aerobic and FAN anerobic bottles (organon Netherlands) were used. The bottles were analysed over a period of 7 days. A total of 600 samples of blood, 108 samples of body fluid, and 100 strains of imitation were detected by mini/VITAL and BacT/Alert parallelly. The bottles of flagged positive were smeared and Gram stained before being examined under a microscope. Subcultures were performed in parallel on fresh blood agar and chocolate agar incubated in microaerophilic Conditions with 5% CO 2. All the bottles flagged negative were examined in the same conditions as the positive bottles. Results mini/VITAL: The positive rate for aerobic and anaerobic blood cultures was 10% and 5% respectively, for aerobic body fluid culture was 26 9%. No contaminants were detected. 0.5% false positive and 0.8% false negative were detected. 90% of positive sample were detected in 48 h. The shortest time of report of positive bottles was 1.5 h for blood culture. BacT/Alert: The rate of positive of aerobic and anaerobic blood culture was 9.8% and 5% respectively. The positive rate of body fluid culturs was 26.9%. There were used 3 bottles contaminated. The false positive and false negative rate were 0.5% and 0 98% respective. 95.5% of positive bottles were detected in 48 h. The shortest time of flagged positive was 2.5 h. Conclusion mini/VITAL and BacT/Alert were accurate automated blood culture systems for the detection of bacteremia. There was no significant difference on the speed of detection between BacT/Alert FAN bottles and mini/VITAL standard bottles.

OBJECTIVE To investigate the variation of in vitro activity,the ?-lactamases,type diversity and the homology of multiple resistances in Acinetobacter isolated.METHODS The multiple resistant Acinetobacter were selected to detect susceptibility test by K-B antimicrobial agents.The resistant rates were analyzed by WHONET 5.4,the isolates ?-lactamases phenotype was detected by three-dimensional test,genomic types were measured by PFGE.The ?-lactamases genotype was determined by PCR assay with specific-primer,and DNA sequencing was also used to analyze resistance-related gene.RESULTS Twenty-eight of 45 strains were OXA producing strains(68.3%),10 strains were IMP producing strains(24.4%),13 strains were TEM producing strains(31.7%),18 strains were CTX-M producing strains(43.9%),6 strains were PER producing strains(14.6%),and 7 strains were AmpC producing strains(17.1%).None produced SHV ?-lactamases.Twenty-four strains were produced 2 or more than 2 kinds of ?-lactamases.CONCLUSIONS The multiple resistance of Acinetobacter can produce kinds of ?-lactamases,but producing ?-lactamases are not the only one mechanism.
