XXXX @entity1944 diagnosed with colonoscopy and analysis of partial 16S rDNA sequences of involved spirochetes.

@entity1 @entity1944 @entity2128
DNA was extracted from colonic biopsies of 33 @entity1 with and three without evidence of @entity1944 ( @entity1944 ) in the large bowel. The biopsies were subjected to PCR. A pair of primers, generating a 207 bp fragment, were designed to detect specifically the 16S rDNA gene of @entity2128 . PCR products of the expected size were obtained from 33 samples with histologic evidence of @entity1944 . The PCR amplicons were used for sequencing. The sequences obtained were aligned to the corresponding 16S rRNA sequences of five type strains of @entity2128 . The sequences of 23 PCR products were 99-100% identical with the corresponding B. aalborgi type strain sequence. Two cases showed 99-100% sequence similarity with the type strain of @entity2128 P43/6/78. Six cases could not be referred to any of the known species of @entity2128 . Two PCR products gave incomplete sequences.
