High-level genetic diversity in the vapD chromosomal region of Helicobacter pylori.

Journal of bacteriology - 1 May 1997

Cao P, Cover T L

Abstract excerpt

Helicobacter pylori isolates from different patients are characterized by diversity in the nucleotide sequences of individual genes, variation in genome size, and variation in gene order. Genetic diversity is particularly striking in vacuolating cytotoxin (vacA) alleles. In this study, five open reading frames (ORFs) were identified within a 4.2-kb region downstream from vacA in H. pylori 60190. One of these ORFs...
