A simple, sensitive method of analyzing bacterial ribosomal DNA polymorphism

Electrophoresis. 1989 Mar;10(3):186-9. doi: 10.1002/elps.1150100306.


A rapid DNA extraction procedure and random primer labelling of Escherichia coli ribosomal RNA with cloned reverse transcriptase have been used to establish a simple and highly sensitive method for studying ribosomal DNA polymorphism in bacteria. Examples of inter- and intraspecies differentiation of bacteria are given and potential applications in bacterial epidemiology and taxonomy are discussed.
