Presence of potentially novel Helicobacter pylori-like organisms in gastric samples from cats and dogs.
Article in Veterinary research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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. A Helicobacter genus-specific 16 S rRNA PCR assay, H. pylori-specific ureAB and glmM PCR assays and a nested PCR detecting 23 S rRNA in a Helicobacter genus-specific manner in a first round of PCR and a H. pylori-specific manner in a second round, were performed in combination with sequencing. Histopathological and anti-Helicobacter immunohistochemical evaluations were also performed. Based on 16 S rRNA sequence analysis, 39/47 animals (83%) appeared infected with canine/feline gastric NHPHs in the corpus and/or antrum. H. pylori-specific ureAB amplicons were obtained in samples of 22 stomachs (47%). One canine antrum sample positive in the ureAB assay was also positive in the H. pylori-specific glmM assay. While 36/47 (77%) animals had a positive sample in the first round of the nested 23 S rRNA PCR assay, all samples were negative in the second round. Sequence analysis of obtained amplicons and immunohistochemistry point towards the presence of unidentified H. pylori-like organisms in cats and dogs. Histopathological examination suggests a low pathogenic significance of the gastric Helicobacter spp. present in these animals. In conclusion, cats and dogs may be (co-)infected with gastric Helicobacter organisms other than the known gastric NHPHs. Culture and isolation should be performed to confirm this hypothesis.
