Abstract

Samples of gastric tissue from the cardiac, fundic and pyloric region of 30 carnivores comprising 12 tigers (Panthera tigris), 10 lions (Panthera leo), three pumas (Felis concolor), two leopards (Panthera pardus), one serval (Felis serval), one wolf (Canis lupus) and one hyena (Crocuta crocuta) kept at German zoological gardens were subjected to histopathological and immunohistochemical examination. Selected tissue specimens of 12 animals were examined also by electron microscopy. The purpose of this study was to determine the prevalence of Helicobacter-like organisms in carnivores and to record infection rates, degree of colonization and associated histopathological changes. Three morphologically different types of spiral-shaped bacteria were demonstrated. A Helicobacter pylori-like organism (HPLO) was found in 42% of the tigers and 90% of the lions examined. Large Helicobacter-like organisms (HLOs) were identified in three pumas, one serval, one hyena and in three lions (in the latter, in coexistence with HPLOs). A third organism with a spiral periplasmic fibril (Helicobacter felis-like) was demonstrated in a wolf. The most striking histopathological finding associated with HPLO and HLO colonization was the formation of lymphoid follicles in the mucosa. Additional lymphoplasmacytic and neutrophilic infiltrates in the gastric mucosa were found in a number of tigers and lions infected with HPLOs, but none in the other carnivores infected with HLOs. From these results it is co…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
