Streptococcus pyogenes

An evaluation of the relative importance of host and pathogen factors on the survival rate of patients with invasive streptococcus pyogenes infection found a number of clinical and demographic factors to be associated with risk for death some evidence suggested a seasonal pattern to patient survival rate. Abstract streptococcus pyogenes can cause a variety of diseases in immunocompetent individuals, from pharyngotonsillitis to life-threatening invasive diseases, such as streptococcal toxic shock syndrome, and rapidly progressing deep-tissue infections, such as necrotizing fasciitis necrotizing fasciitis is often seen in combination with streptococcal toxic shock syndrome, which further. Introduction life-threatening infections caused by streptococcus pyogenes (group a streptococcus) include scarlet fever, bacteremia, pneumonia, necrotizing fasciitis, myonecrosis and streptococcal toxic shock syndrome (streptss) this chapter focuses on the clinical and epidemiological features of these infections, as well as treatment options and bacterial pathogenesis.
