2020-11-12 · The various strains of group A streptococcus (GAS) all belong to one species— Streptococcus pyogenes. Strains are slightly different members of a species. As in the case of group A streptococci, the different strains of group B streptococcus (GBS) all belong to one species—in this case, Streptococcus agalactiae. Streptococcus pyogenes, also known as the Group A Streptococcus (GAS), is a remarkable human pathogen that causes a diverse spectrum of disease [ 1 ]. The majority of GAS diseases are relatively mild, superficial infections of the throat (pharyngitis, or ‘Strep throat’) and skin (impetigo, or ‘skin sores’). Streptococcus pyogenes (or Group A Streptococcus, GAS) is a Gram-positive human pathogen responsible for a diverse array of superficial, invasive and immune-related diseases. GAS infections have historically been diseases of poverty and overcrowding, and remain a significant problem in the developing world and in disadvantaged populations within developed countries.

Cell wall of Streptococcus pyogenes is made up of an outer layer of protein (fimbria containing protein) and lipoteichoic acid, middle layer of group-specific carbohydrate and an inner layer of peptidoglycan. Group A Streptococcus (GAS) is the etiologic agent of numerous high-morbidity and high-mortality diseases. Infections are typically highly proinflammatory. During the invasive infection necrotizing fasciitis, this is in part due to the GAS protease SpeB directly activating interleukin-1β (IL-1β) independent of the canonical inflammasome pathway.
