Abstract: The present invention relates to the field of biosensors useful for detecting bacteria. More particularly, the present invention relates to an electrochemical cell or biosensor and its use in a phage-based method and kit for the detection of bacteria.

Abstract: The present invention is concerned with genetically labeled bacteriophages, and with methods for preparing and using the same. Genetically labeled phages may easily be distinguished from non-labeled phages. The present invention also relates to methods for selecting therapeutic bacteriophages lysing pathogenic bacteria without cross-reacting with non-pathogenic bacteria. This method permits the selection of phages which are highly specific to given pathogenic bacteria. The present invention is also concerned with methods for evaluating bacteriophage susceptibility to external genetic modifications in order to provide bacteriophages that are safe and highly specific for use in the prevention, treatment and/or control of bacterial infections or contamination in plants, animals, and humans, as well as environmental cleanup and sanitation.
