Streptococcal Infections

Streptococcus types:

	Group A streptococci Group A streptococci (Streptococcus pyogenes ) cause a wide-range of disease in humans, from mild sore throats to life-threatening invasive disease such as necrotising fasciitis. Information on Group A streptococci
	Group B streptococci Group B streptococci (Streptococcus agalactiae ) can form part of the normal human flora, but under certain conditions they may act as opportunistic pathogens causing severe disease, especially in infants. Information on Group B streptococci
	Group C and G streptococci Group C and G streptococci encompass several different species that can cause severe disease in man such as meningitis and septicaemia, as well as ear, eye and throat infections. Information on Group C and G streptococci
	Non-pyogenic streptococci Non-pyogenic streptococci are a diverse group of bacteria, normal inhabitants of the mouth, throat and occasionally the gastrointestinal tract. 'Silent bacteraemia' can be caused by these organisms especially in individuals with poor dental hygiene or gum disease. Information on non-pyogenic streptococci
	Streptococcus pneumoniae Streptococcus pneumoniae (pneumococcus) can cause invasive and non-invasive pneumococcal disease. Invasive pneumococcal disease (IPD) includes septicaemia, pneumonia and meningitis. Information on Streptococcus pneumoniae
