Group A streptococcus (GAS) is synonymous with Streptococcus pyogenes, the only species within this group of β-hemolytic streptococci. GAS is one of the leading pathogenic bacteria that infects children and adolescents, and is associated with a wide spectrum of infections and disease states. Worldwide, there are estimated to be >600 million cases of GAS pharyngitis (“strep throat”) and >100 mil...

Studies on Streptococcus Pyogenes

Electron microscopic observations of Streptococcus pyogenes (strain S43, type 6) treated with trypsin and cetyltrimethylammonium bromide (Cetab) are presented. The concentration of trypsin necessary to remove the M protein antigen was shown to bring about a partial digestion of the cells. The cell protoplasm and protoplasmic membrane were affected. No microscopic changes appeared in the cell wa...

Neonatal Sepsis: An Update

Sepsis is the most common cause of neonatal mortality. As per National Neonatal-Perinatal Database (NNPD), 2002-2003, the incidence of neonatal sepsis in India was 30 per 1000 live births. Signs and symptoms of sepsis are nonspecific; therefore empirical antimicrobial therapy is promptly initiated after obtaining appropriate cultures. The early manifestations of neonatal sepsis are vague and il...
