Diagnostic value of the rapid influenza antigen test for novel influenza A (H1N1).

We administered both the rapid antigen test and real-time reverse transcriptase polymerase chain reaction (RT-PCR) test to 2154 patients in order to assess the diagnostic value of the rapid antigen test during Korean pandemics of H1N1 2009. The overall sensitivity was 70.0%, specificity was 97.

The resistance mechanisms of b-lactam antimicrobials in clinical isolates of Acinetobacter baumannii.

Background: Despite increasing importance of Acinetobacter baumannii in nosocomial infections and rapid development of multi-antimicrobial resistance in this strain, the resistance mechanisms of beta-lactam antimicrobials in A. baumannii were not clearly defined. In order to observe the resistance mechanisms against beta-lactams and carbapenem, we characterized the production of beta-lactamases and outermembrane protein (OMP) profiles for the 44 clinical isolates of A.
