BACKGROUND AND PURPOSE In order to reduce the turnaround time for laboratory diagnosis of bacteremia, the efficacy of identification and antimicrobial susceptibility testing using samples taken directly from positive BacT/ALERT standard aerobic and standard anaerobic blood culture bottles was evaluated. METHODS 160 positive blood culture bottles were examined and incubated at 35 degrees C in ...

Injection of endotoxin of Gram-negative bacilli into NCS mice caused an immediate reduction or interruption of water intake by these animals, with a resultant loss of body weight. Endotoxins prepared by three different techniques from four different cultures of Gram-negative bacilli yielded products having approximately the same activity in inhibiting water intake. The minimum effective dose wa...

181 patients undergoing resection of the oesophagus for carcinoma were randomised to receive selective decontamination (test group) or conventional perioperative antibiotic prophylaxis (controls). 114 patients were finally included in the study: 12 of 56 test patients had 18 infections, whereas 32 of 58 controls acquired 51 infections. Colonisation with aerobic gram-negative microorganisms, and...
