An. Suvorov et Jj. Ferretti, PHYSICAL AND GENETIC CHROMOSOMAL MAP OF AN M-TYPE-1 STRAIN OF STREPTOCOCCUS-PYOGENES, Journal of bacteriology, 178(18), 1996, pp. 5546-5549
A physical map of the chromosome of an hi type I strain of Streptococc
us pyogenes was constructed following digestion with three different r
estriction enzymes, SmaI, SfiI, and SgrAI, and separation and analysis
of fragments by pulsed-field gel electrophoresis. The genome size of
this strain was estimated to he 1,920 lih. By employing Southern hybri
dization and PCR analysis, 36 genes were located on the map.
