Streptococcus bacteria cause infections such as strep throat, cellulitis, meningitis, bacterial pneumonia, endocarditis, scarlet fever, and rheumatic fever. They grow in chains or pairs. There are various types or species of Streptococci (strep) bacteria.The two groups briefly discussed here are from group A Streptococcus pyogenes GAS and group B Streptococcus agalactiae GBS. Nonpathogenic forms of strep bacteria normally live on the skin, inside the mouth, nose, throat, and inside the intestines.treptococcal bacteria are not always the culprit.
