Abstract: The present invention relates to a method for enhancing the time of response of an assay for a first bacterium, wherein: a) the first bacterium is exposed to infection by phage particles to which the first bacterium is permissive; b) the infected bacterium is treated to inactivate exogenous phage particles; c) the treated bacterium is cultivated in the presence of a second bacterium which is permissive to infection by the phage or its replicand and which has a doubling rate greater than the effective doubling rate of the first bacterium; and d) assessing the extent of plaque formation and/or of second bacterium growth in the cultivated second bacterium cells.

Abstract: A method of identifying a nucleic acid sequence in a biological sample comprises using a pair of universal oligonucleotide primers to amplify the nucleic acid sequence and characterizing the amplification reaction products. Preferred universal primers are derived from conserved regions of cold shock or Y-box proteins and hybridize to the genes that code for the peptide sequences GXVKWFNXXKGFGFI and GPXAXNVTXX.
