We report the case of a 9-year-old boy who presented with chronic rectal bleeding. On proctosigmoidoscopy, a polypoid elevation in the rectal ampulla measuring 5 x 3 cm was found. Biopsies were reported to show gastric mucosa. The Giemsa stain showed Helicobacter pylori-like organisms. Including our patient, there are now 30 similar cases reported in the medical literature. The usual manifestations of this rare entity are chronic bleeding and rectal pain. In one-half of cases there is chronic rectal ulceration. The recommended treatment is transanal surgical resection unless there is rectal peptic ulceration. H2 receptor blockers are then advised. Surgical excision is carried out after healing has taken place.

This study investigated the role of causative infectious agents in ulceration of the non-glandular part of the porcine stomach (pars oesophagea). In total, 150 stomachs from slaughter pigs were included, 75 from pigs that received a meal feed, 75 from pigs that received an equivalent pelleted feed with a smaller particle size. The pars oesophagea was macroscopically examined after slaughter.

While seven gastric non-Helicobacter pylori Helicobacter (NHPH) species are known to commonly colonize the stomach of cats and dogs, the potential of H. pylori and H. pylori-like organisms to infect animals remains controversial and was investigated in this study using gastric samples of 20 cats and 27 dogs.

Antimicrobial resistance is a major public health concern. The aim of this study was to assess the presence of antibiotic resistance genes, previously reported in in gastric samples of 36 pigs, in which DNA of -like organisms had been detected. Based on PCR and sequencing analysis, two samples were positive for the mutation gene, conferring tetracycline resistance, and one sample was positive for the gene with a single nucleotide polymorphism, conferring metronidazole resistance.

Besides Helicobacter pylori, a Gram-negative bacterium that may cause gastric disorders in humans, non-Helicobacter pylori helicobacters (NHPH) may also colonize the stomach of humans and animals. In pigs, H. suis can induce gastritis and may play a role in gastric ulcer disease, possibly in association with Fusobacterium gastrosuis.
