Isolation of Campylobacter fetus subsp. jejuni from migratory waterfowl
Abstract:
Since the sources from which humans acquire Campylobacter enteritis are only partially known, we studied the frequency of carriage of Campylobacter fetus subsp. jejuni in migratory waterfowl. Cecal contents of various species of wild ducks were cultured on selective media that contained antibiotics to inhibit normal flora. Thirty-five percent of the 445 ducks cultured harbored C. fetus subsp. jejuni. Migratory waterfowl are yet another reservoir for this enteric pathogen and may be of public health importance for humans in the contamination of water or when used as food.
Insights
Migratory waterfowl carry Campylobacter fetus subsp. jejuni, a cause of human enteritis. This finding highlights a potential public health risk through water or food contamination.
Area of Science:
- Veterinary Microbiology
- Food Safety
- Public Health
Background:
- Human Campylobacter enteritis is a significant public health concern.
- The primary sources of human Campylobacter infections are not fully understood.
- Campylobacter fetus subsp. jejuni is a common cause of bacterial gastroenteritis.
Purpose of the Study:
- To investigate the prevalence of Campylobacter fetus subsp. jejuni in migratory waterfowl.
- To identify migratory birds as a potential reservoir for this enteric pathogen.
Main Methods:
- Culturing of cecal contents from 445 wild ducks using selective antibiotic-containing media.
- Identification of Campylobacter fetus subsp. jejuni in cultured samples.
Main Results:
- Campylobacter fetus subsp. jejuni was detected in 35% of the sampled ducks.
- Migratory waterfowl were confirmed as carriers of the pathogen.
Conclusions:
- Migratory waterfowl represent a significant reservoir for Campylobacter fetus subsp. jejuni.
- Waterfowl may pose a public health risk through environmental contamination (water) or food sources.
