Unformatted text preview: METHODS OF CLASSIFYING AND IDENTIFYING MICROORGANISMS SEROLOGY--- his is the science that studies blood serum and immune responses that can be measured in serum. When microorganisms enter the body, one of the responses is the formation of proteins called antibodies. Antibodies circulate in the blood. When they come in contact with the microbe that stimulated their production, they combine with it and inactivate it in some way. This can be used for identification. Solutions containing known antibodies can be prepared--- they are called antisera (antiserum = one). Samples of an unknown bacterium can be placed on slides and mixed with several likely antisera. If there is a match, the bacteria will clump together (agglutinate). This is a slide agglutination test. Serological testing can even distinguish between strains of the same species. Strains with different antigens are called serotypes, serovars, or biovars. Streptocccci were originally sorted different antigens are called serotypes, serovars, or biovars....
