Isolation of Pure Populations of Helicobacter heilmannii-like Bacteria
Large spiral bacteria similar in morphology to Helicobacter felis are common in the stomachs of many animal species including cats, dogs, pigs, non-human primates, and a variety of wild carnivores.1, 3–5, 8 These bacteria, first referred to as spirilla,5, 10 and later as Gastrospirillum sp,6 are most likely members of the helicobacter genus. Several isolates have been given the provisional name, H. heilmannii. 9 They are not culturable in vitro, however, and speciation has been limited to PCR amplification and sequencing of bacterial 16S rRNA genes in infected gastric scrapings.9 Thus, study of these bacteria is hindered by the lack of pure populations free from contaminating bacteria and other debris.
