Campylobacter jejuni abortion in a heifer.
Journal of the American Veterinary Medical Association
|September 1, 1984
Summary
Campylobacter jejuni was identified in an aborted bovine fetus, distinct from common causes of bovine campylobacteriosis. Accurate identification is crucial for herd health and public health due to C. jejuni
Area of Science:
- Veterinary Microbiology
- Bovine Infectious Diseases
- Foodborne Pathogens
Background:
- Campylobacter species are significant causes of abortion in cattle.
- Distinguishing between different Campylobacter species is essential for effective disease management.
- Campylobacter jejuni is a common cause of human gastroenteritis.
Purpose of the Study:
- To identify and characterize a Campylobacter isolate from an aborted bovine fetus.
- To differentiate the isolate from common bovine Campylobacter pathogens.
- To highlight the public health implications of identifying Campylobacter jejuni in cattle.
Main Methods:
- Isolation of bacteria from fetal lung and stomach contents.
- Morphologic, biochemical, and thermotolerance characterization.
- Antibiotic sensitivity testing and serotyping.
Main Results:
- The isolate was identified as Campylobacter jejuni.
- Serotyping excluded the isolate from Campylobacter fetus subsp. venerealis and Campylobacter fetus subsp. fetus.
- The isolate exhibited specific antibiotic sensitivity patterns.
Conclusions:
- Campylobacter jejuni can cause abortion in cattle, necessitating careful speciation.
- Accurate identification of Campylobacter species is vital for herd health management, especially when abortion rates remain high despite vaccination.
- Public health awareness is important as C. jejuni is a frequent cause of human infections.
