Helicobacter pullorum sp. nov.-genotype and phenotype of a new species isolated from poultry and from human patients with gastroenteritis

Nucleotide sequence analysis, DNA studies and electrophoretic analysis confirm that the organisms resembling Campylobacter, isolated from gastroenteritis-affected humans belong to a class of species of Helicobacter genus. These species, named Helicobacter pullorum sp. nov. do not have a sheathed flagellum. Specific PCR assays enable further studies of these organisms.
