Abstract:
The role of Helicobacter spp. infection in canine gastrointestinal disease is unclear and routes of transmission are of epidemiological and zoonotic importance. The aim of this study was to identify Helicobacter spp. in the saliva, stomach, duodenum and faeces of dogs using a multiplex PCR, and to evaluate any attendant histopathological changes. Helicobacter canis was the most common species detected in saliva and faeces and no correlation between the presence of Helicobacter spp. and histopathological changes in either the stomach or duodenum was observed. All dogs examined were co-infected with up to four species of the organism. This is the first time these bacteria have been studied at species level at multiple sites within the canine alimentary tract.
