Gastric Helicobacter infection in dogs
1Department of Clinical Sciences, College of Veterinary Medicine, Cornell University, Ithaca, New York, USA.
Summary
Canine gastric Helicobacter infections are common but often asymptomatic. Diagnosis is challenging, with noninvasive methods like UBBT and serology showing future potential for detecting these common dog stomach bacteria.
Area of Science:
- Veterinary Medicine
- Microbiology
- Canine Health
Background:
- Gastric Helicobacter spp. infections are prevalent in dogs.
- Most infected dogs remain asymptomatic, complicating diagnosis and management.
- Five distinct Helicobacter species have been identified in canine stomachs.
Purpose of the Study:
- To review the prevalence and diagnostic challenges of gastric Helicobacter infections in dogs.
- To explore potential transmission routes for canine Helicobacter.
- To highlight promising noninvasive diagnostic techniques.
Main Methods:
- Literature review of studies on canine gastric Helicobacter.
- Analysis of identified Helicobacter species in dogs.
- Evaluation of diagnostic methods, including invasive and noninvasive approaches.
Main Results:
- Canine gastric Helicobacter infections are widespread.
- Transmission pathways, including fecal-oral, oral-oral, and waterborne routes, are suspected but not fully understood.
- Current diagnostic methods include invasive biopsy-based tests.
Conclusions:
- Noninvasive diagnostic techniques, such as the urea breath test (UBBT) and serology, offer a promising future for diagnosing canine gastric Helicobacter infections.
- Further research is needed to elucidate transmission routes and improve diagnostic accuracy.
