[Quantitative microbiological diagnostic method of intravascular catheters infection using the BacT/Alert SA bottles].

Objective: The study describes a method of quantitatively examining vascular catheters with the aid of hemocultural devices BacT/Alert.

Material And Methods: The amount of bacteria present on the surface of the vascular catheters was determined based on the time to detection (TTD) in hemocultural vials inoculated with bacterial suspension stirred off the catheter surface.

Results: A total number of 348 vascular catheters was examined with this new method.

[Growth and detection of aerobic bacterial pathogens in BacT/Alert FA, BacT/Alert SA, Bactec Plus Aerobic/F and Bactec Standard Aerobic/F].

The article compares the ability of detection and detection times (TTD) of aerobic bacteria in the BacT/Alert FA, BacT/Alert SA, Bactec Plus Aerobic/F and Bactec Standard Aerobic/F bottles. Compared bottles were inoculated at the same time with the identical suspension of bacterial strain. All bottles detected bacterial pathogens even in the case of very low number of inoculated bacteria.

Simultaneous determination of nitrendipine and one of its metabolites in plasma samples by gas chromatography with electron-capture detection.

A sensitive method for GC-ECD simultaneous determination of nitrendipine and its pyridine metabolite M1 in human plasma is described. Felodipine was used as the internal standard. The plasma samples were extracted with toluene.
