The differences in colonic mucosal microbiota between normal individual and colon cancer patients by polymerase chain reaction-denaturing gradient gel electrophoresis.OBJECTIVE
 Thereafter, a comparison of the microbiota structure by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) was carried out. 
polymerase chain reaction-denaturing gradient gel electrophoresis
Thereafter, a comparison of the microbiota structure by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) was carried out.  With PCR-DGGE, we have discovered that the diversity and richness of the bacterial community from colon cancer patient's colonic mucosa were lower than that of the normal individual's sample.
