The Streptococcal Genome

The advent of recombinant DNA technology and recent deciphering of the genomes of S. pyogenes serotypes M1,[9] M3,[10] and M18[11] have taught much about the organism's virulence and pathogenicity mediated by both cell-associated and extracellular products. They have also allowed the discovery of a number of strep-tococcal superantigens.

The sizes of these three genomes are ca. 1.85, 1.90, 1.89 bp, respectively, and open reading frames (ORF) range between 1752 and 1895. Approximately, 1500 ORF are conserved between the three serotypes. Four to six bacteriophage genomes were identified per bacterial chromosome confirming that many cell-associated and extracellular factors are encoded by phage genome.

Getting Started With Dumbbells

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.
