One way of identifying and categorizing multiple bacterial organisms in a sample is to use ribotyping. In ribotyping, differing lengths of chromosomal DNA are isolated from samples containing bacterial species, and digested into fragments. Similar types of fragments from differing organisms are visualized and their lengths compared to each other by Southern blotting or by the much faster method of polymerase chain reaction (PCR). Fragments can then be matched with … Web23 de set. de 2016 · After isolation, genus and species level identification is carried out, for which commercially available panels of biochemical tests are frequently employed; these …
