Performance evaluation of the βLACTA™ Test for rapid detection of ceftazidime resistance in Pseudomonas aeruginosa isolates from cystic fibrosis patients.

The chromogenic βLACTA™ test was evaluated to detect ceftazidime resistance in P. aeruginosa isolates from patients with cystic fibrosis. Best results were obtained after one hour of incubation with low sensitivity (64.

Multiplex PCR performed of bronchoalveolar lavage fluid increases pathogen identification rate in critically ill patients with pneumonia: a pilot study.

Background: In critically ill patients with pneumonia, accurate microorganism identification allows appropriate antibiotic treatment. In patients undergoing bronchoalveolar lavage (BAL), direct examination of the fluid using Gram staining provides prompt information but pathogen identification accuracy is low. Culture of BAL fluid is actually the reference, but it is not available before 24 to 48 h.
