Helicobacter pylori is a gram-negative, microaerophilic bacterium that infects the gastrointestinal system of animals and humans causing peptic ulcers and other gastroenterological distress. Although H. pylori does not natural infect rodents, infections can be common among research animals due to its use as a research model.
Most cases of H. pylori infection do not display any signs or symptoms, however, this may be a result of the individual’s resistance to H. pylori’s painful effects. In many species, signs or symptoms do occur with H. pylori infection, which may include:
- Poor appetite.
- Bowel sounds.
- Abdominal pain.
- Weight loss.
