“…This is consistent with preliminary data reported in ferrets surveyed in both Canada and England (J. A. Hollingsworth, unpublished data) (13). There was a much lower isolation rate (3 of 17 [18%]) from neonatal and juvenile ferrets, implying that colonization probably occurs after weaning (age, -6 weeks).…”

Gastric colonization by Campylobacter pylori subsp. mustelae in ferrets

et al. 1988

Campylobacter pylori subsp. mustelae was cultured from both normal and inflamed gastric mucosa of ferrets. Examination of neonatal, juvenile, and adult ferrets established that the gastric mucosa in the majority of preweanling (age, less than 6 weeks) ferrets sampled were not colonized with C. pylori subsp. mustelae, whereas the gastric mucosa of 100% of adult ferrets were colonized with this gastric organism. C. pylori subsp. mustelae was isolated from the gastric mucosa on a sequential basis from nine ferrets during a several-month period, inferring either persistent colonization or frequent reinfection with C. pylori subsp. mustelae.

“…Shortly after the publication in 1984 of the seminal observations of Marshall and Warren, a Campylobacter-like organism was isolated by Fox et al from gastric tissue of one ferret with a gastric ulcer and from two others with normal gastric mucosa (148). This observation was quickly confirmed by others (331,396). The ferret organism was morphologically and biochemically very similar to what was then called C. pylori, and it was originally designated C. pylori subsp.…”

“…Like H. pylori, infection with H. mustelae is apparently persistent. H. mustelae is widespread among colonies of laboratory ferrets (180,331,396) and has also been seen in ferrets kept as pets (156). Although examination of adult ferrets from one New Zealand pelt farm failed to find any evidence of infection (290), more recently H. mustelae has been isolated from captive and wild ferrets in New Zealand (131).…”

Emergence of DiverseHelicobacterSpecies in the Pathogenesis of Gastric and Enterohepatic Diseases

2001

Since Helicobacter pylori was first cultivated from human gastric biopsy specimens in 1982, it has become apparent that many related species can often be found colonizing the mucosal surfaces of humans and other animals. These other Helicobacter species can be broadly grouped according to whether they colonize the gastric or enterohepatic niche. Gastric Helicobacter species are widely distributed in mammalian hosts and are often nearly universally prevalent. In many cases they cause an inflammatory response resembling that seen with H. pylori in humans. Although usually not pathogenic in their natural host, these organisms serve as models of human disease. Enterohepatic Helicobacter species are an equally diverse group of organisms that have been identified in the intestinal tract and the liver of humans, other mammals, and birds. In many cases they have been linked with inflammation or malignant transformation in immunocompetent hosts and with more severe clinical disease in immunocompromised humans and animals. The purpose of this review is to describe these other Helicobacter species, characterize their role in the pathogenesis of gastrointestinal and enterohepatic disease, and discuss their implications for our understanding of H. pylori infection in humans
