Streptococci are a group of gram-positive spherical bacteria, arranged in pairs or chains, have the ability to produce lactic acid as the end result of sugar fermentation. They are widely distributed in nature. Some species are part of the normal human flora, while others can cause disease in both humans and animals. The objective of the following research is to know the classification of bacteria of the streptococcus genus and the pathologies they can cause. The methodology used for the resolution of this case study is descriptive, it was carried out through the review of scientific articles, with which it is concluded that for the classification of these bacteria several systems can be used such as: the groups of serotypes according to Lancefield, the ability to produce hemolysis in blood agar plates, biochemical and molecular tests. Also, the most important pathologies caused by these microorganisms are: tonsillitis, impetigo, scarlet fever, pneumonia, streptococcal shock syndrome, among others.
