Most PCR assays developed for the detection of EHEC target the stx and eae genes and their various alleles. However, because the EHEC group comprises many serotypes that are genotypically and phenotypically diverse, identification of specific strain requires the detection of other putative virulence genes or markers that are unique to O157:H7 or other serotypes. Multiplex

PCR assays, which enable the simultaneous detection 13. of multiple genes, are very useful in the diagnosis of specific EHEC serotypes and the virulence factors carried by these pathogens.

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
