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. Streptococcal bacteria are not exclusive to all the types of diseases listed below. For example, endocarditis can also be caused by fungi or other germs. Another example is pneumonia, that may be caused by viruses, parasites, fungi, or noninfectious lung diseases.
