Strept-ppt

They are spherical, Gram-positive cocci arrange in long or short chain, also form pairs diplococcic (Streptococcus pnumoniae) lancet shape (head to head), due to cell division in one plane only. They are non-motile, non-spore forming, catalase negative (help to distinguish them from Staphylococcus). Some species are encapsulated.
Streptococcus species are widely distributed in nature. Some are members of the normal human flora mostly residents in mouth, throat and intestine, also may act as opportunistic pathogens and few species (Streptococcus pyogenes and Streptococcus agalactiae) as primary pathogens.
