Using Streptococcus pneumoniae as an example, this solution describes how serological tests can distinguish between multiple different serotypes of a bacterial species. S. pneumoniae has over 80 different serotypes; however, serological reactions are sensitive enough to differentiate the various serotypes.© BrainMass Inc. brainmass.com October 2, 2022, 11:16 am ad1c9bdddf

Each serotype of Streptococcus pneumoniae has differences in the identity of the surface proteins, some of which may only be a small number of amino acids. Antibodies bind very specifically to a given serotype of bacteria, and the binding can be abrogated by as little as one amino acid change. Therefore antibodies against one serotype do not cross-react with other serotypes.© BrainMass Inc. brainmass.com October 2, 2022, 11:16 am ad1c9bdddf>
